10 Ways to E-Boost Your Brain
In this era of modern technological advances, it’s
easy to put your brain on pause and let computers, PDAs
or televisions do the thinking for you, but there are
ways to let technology work for your brain, to keep
it fresh and build it stronger. You may never become
the bionic man, but with recent research showing that
the brain continues to grow late in life, it’s
never too late for an e-boost. ~Photo Here
1. Surf the Web: A recent study hinted at the possibility
that using an
online search engine for an hour a day can boost your
overall brain activity. (Keep it in moderation, though,
lest you develop Attention Deficit Disorder or severe
social ineptitude.)
2. Use a Wii: If the evidence that exercise increases
brain growth
doesn’t get you up and moving, consider the fact
that obese people have an elevated risk of developing
Alzheimer’s. Abdominal fat in particular secretes
inflammatory chemicals that affect the brain, so get
a Wii Fit and start doing some crunches!
3. Listen to iTunes: There is evidence that certain
music can increase your
learning and retention ability, as well as your concentration
and alertness. The bad news: that music is in High School
Musical 3.
4. Play Games: Recent studies have shown that puzzles
and word games can
improve your ability to focus, and there are dozens
of free crossword and suduko websites online, in addition
to newspaper sites that regularly feature such puzzles.
Even video games can increase cognitive abilities, even
if you don’t play ones targeted at your brain,
like Big Brain Academy, Mega Brain Boost or Brain Age.
5. Watch TV Shows: What?!? There is a God! Yes, there
is evidence that
contradicts popular belief that TV turns viewers into
drooling zombies, and one study found that kids who
watched more TV early in life did slightly better on
standardized tests. Of course, it largely depends on
what is being watched, so don’t expect those hours
of Knight Rider reruns to turn you into a genius. The
good news is that nowadays, you don’t even have
to have a TV to watch TV, as networks put more and more
content on their websites and on general sites like
the Internet Movie Database.
6. Read an E-Book: This is a no-brainer (pun intended),
but reading is good
for your brain. Reading not only helps you learn and
boosts your vocabulary, but it also trains your brain
to become more focused, increasing your memory and ability
to reason. You can download free books at sites like
Project Gutenberg, the Internet Archive and Google,
or you can use e-book readers like Amazon.com’s
Kindle if you’re on the go. (I hear Oprah loves
it.)
7. Be Optimistic: According to recent studies, the
power of positive
thought could be the real deal, with optimistic people
suffering fewer strokes and recovering more quickly
than pessimists. Browse the myriad of motivational,
inspirational and self-improvement sites on the Web
and find one that strikes a chord with you.
8. Laugh: Laughing stimulates the brain and other organs
(insert joke
here), so do it more by frequenting sites like The Onion,
Funny or Die or C-SPAN (Funny is in the eye of the beholder.).
9. Take a Quiz: It’s a fact: nerds live longer.
Have you ever seen a
burly, athletic 90-year-old? Tap into your inner nerd
by acing online trivia quizzes on sites like triviaplaza.com
and funtrivia.com, then laugh at all the jocks who will
die young.
10. Stimulate Yourself: It all comes down to stimulation.
Practically
anything that stimulates the brain is a good thing,
and Lord knows there’s plenty of stimulation on
the Internet. One of the keys is to avoid a stagnant
routine. Learn a new language, visit new sites, pick
up new hobbies, study new topics. Just don’t limit
yourself to your usual bookmarked sites (Sorry, Stuff
On My Cat.).

Can Thinking Too Much Make You Fat?
Online students beware: a new study conducted by researchers
at Universite Laval in Quebec, Canada, indicates that
heavy thought might contribute to obesity. The limited
study — apparently, there are only 14 obese people
in Quebec — suggests that intellectual activity
causes increased fluctuations in glucose and insulin levels
in your body. Since glucose is the only fuel used by brain
cells, the brain may in turn tell the body to replenish
the burned glucose by eating more.
In the study, the subjects were given food after three
separate activities: relaxing in a chair, writing a 350-word
summary of a document and engaging in a comprehensive
battery of tests on a computer. Compared to the feeding
time after the relaxation period, the subjects ate an
average of 203 more calories after writing the summary
and 253 more calories after taking the computerized tests.
As icing on the fattening cake, they burned only THREE
more calories during the “brainy” events than
they did while relaxing, resulting in a net 200 and 250
caloric increase after the intellectual activities. Online
students, of course, get the double whammy of not only
craving more food due to increased brain function, but
also experiencing the decreased physical activity of spending
all their time in front of a computer. Linked with other
studies that suggest that obesity decreases your brain
function, it’s not hard to come up with this bleak
equation: studying = weight gain = stupidity. Ergo, studying
makes you stupid. (Having drawn that equation, I suddenly
need a sandwich.) Of course, it’s not that simple.
There are many other factors that contribute to weight
gain — diet, physical activity, heredity —
and even if you do find your cravings increase while studying,
you can counter them by eating healthy foods and by taking
time out to exercise a few minutes a day.

Supplements for Food Cravings
Here are some supplements to help with food cravings.
Some of these are backed by scientific studies and some
are not.
§ Try amino acids: Tyrosine, phenylalanine, gamma-aminobutyric
acid
(GABA), tryptophan, and glutamine all seem to help with
cravings. These amino acids do two things: first they
provide the body with needed nutrients and secondly,
they are building blocks of brain chemicals (like
serotonin) that help modulate both mood and cravings.
§ B-complex: B-vitamins are also important co-factors
in building brain
chemicals and are generally lacking in our diets.
§ Minerals: Chromium, magnesium and calcium have
all been shown to help
with food cravings.
§ Balance blood sugar: Many herbs such as Gymnema
and supplements such as
chromium, vanadium have been shown to help stabilize
blood sugar, which is also thought to play a role in
food cravings.
§ A good multi-vitamin: Multi-vitamins can help
quell cravings. Many
include the B-vitamins and minerals (as mentioned above).
§ Exercise: Exercise reduced chocolate urges and
there was a trend
towards attenuated urges in response to the chocolate
cue.

Brain Myths—Busted
Five examples of neurological nonsense you can forget
about for good. ~Photo here By Rich Maloof for MSN Health
& Fitness The human brain has received unprecedented
press coverage in the past few years, thanks in large
part to big leaps in science's understanding of what goes
on in the space between our ears. Yet, some stubborn myths
remain.
For this special installment of Brain & Body, we're
offering insights into which commonly held beliefs stem
from reliable studies in neuroscience—and which
are just plain mindless. For further information on these
fallacies, we've consulted our favorite research neuroscientist
and go-to brain guy, Istvan Molnar-Szakacs, Ph.D., of
the Semel Institute's Tennenbaum Center for the Biology
of Creativity at UCLA.
Myth: Listening to Mozart makes
you smarter.
Reality: It may make you
feel superior, but listening to Mozart won't make you
any smarter than bumping along to the latest cut by Lil'
Wayne. The Mozart idea first took hold following a 1993
study published in Nature that showed that 12 students
scored higher on a spatial IQ test after listening to
a Mozart sonata. Author Don Campbell ran with the notion
in his pop-psychology book The Mozart Effect, and a multi-million–dollar
industry arose selling CDs and videos to parents holding
out hope their little ones would harness the intellectual
power of Amadeus. However, subsequent research failed
to replicate the (small) study's results. And the original
researchers later re-emphasized the qualifications in
their findings; notably, that the effect was temporary,
not extending beyond 10 or 15 minutes. "The myth
does bring attention to the value of music as a tool for
stimulating the brain," says Molnar-Szakacs. "We
know that playing a musical instrument in childhood improves
performance in academic areas other than music. But just
listening to Mozart while cramming for a test is no reliable
way to improve your score, let alone your IQ."
Myth: People with autism have
genius talents.
Reality: There's not a great deal known about savant
syndrome, the very curious condition in which people with
developmental disorders such as autism show astonishing
skills in music, art, or math. But we do know that the
widespread misconception about its prominence is traceable
to the 1988 film "Rain Man," and that the movie's
hero would be exceptionally skilled, and exceptionally
rare, even among savants. According to Darold A. Treffert,
M.D., of the Wisconsin Medical Society—a recognized
expert on savant syndrome— approximately one in
10 people with autism spectrum disorder has some savant
skills. (Among those with other developmental disabilities,
fewer than 1 in 100 are savants.) Treffert estimates that
no more than 50 people in the world are "prodigious
savants" like the toothpick-counting character portrayed
by Dustin Hoffman.
Beware the characterization of genius, too. The famous
"calculating twins" written about by Oliver
Sacks, M.D., in The Man Who Mistook His Wife for a Hatcould
see prime numbers in a fallen stack of matches or tell
you which day of the week July 4 would fall on in the
year 3024, but they couldn't do simple multiplication.
Myth: Smarter animals have bigger
brains.
Reality: A sperm whale's brain is more than five
times the weight of a human's—yet the animal with
the world's largest brain still can't play a decent game
of chess. What gives? "The relationship isn't directly
between brain size and smarts, but rather in the ratio
of brain weight to body weight and smarts," explains
Molnar-Szakacs. "In a human, whose brain weighs around
3 pounds, the ratio is about 1:50. But in other mammals
it's closer to 1:80 or 1:200. So, the smaller the ratio,
the more intelligent the animal." Molnar-Szakacs
adds that, even beyond the brain-to-body weight ratio,
it is what's inside the cranium that counts. "The
parts of the human brain that control higher cognitive
functions are the cerebral cortices," he says. "These
are the areas responsible for the uniquely [high-functioning]
human abilities of language, memory, and planning for
the future. The cerebral cortices enable us to learn and
adapt our responses to our environment in much more sophisticated
ways than other animals. For example, we have the capability
to override predominant, stimulus-driven responses, so
that we can say 'no' to chocolate cake if it'll break
our diet even if we are still hungry and know it would
taste really good."
Myth: Drink enough alcohol and
you'll start killing brain cells.
Reality: Drunken frat boys head-butting one another
in a bar may give you pause to consider this one, but
alcohol does not kill neurons or create holes in the brain.
However, there's no denying that alcohol and other drugs
of abuse impact brain systems. It's their effect on the
neurotransmitters dopamine and serotonin that goose the
brain's reward system, leading to feelings of euphoria—and,
when more of the drug is needed to create the same effect,
to tolerance and addiction. "Over the short-term,
alcohol and drugs alter brain function rather than affecting
brain structure," Molnar-Szakacs clarifies. "Slurred
speech, impaired motor response, and impaired judgment
are all symptomatic of compromised frontal lobes, the
centers of the brain that direct higher-level decision
making." Rarely, a chronic drinker may develop Wernicke-Korsakoff's
Syndrome, a condition characterized by atrophy or shrinking
of the thalamus and hypothalamus and the inability to
recall or form memories. This syndrome's not a direct
effect of drinking, but rather a secondary result of alcohol
abuse so severe that absorption of vitamin B-1 is prevented,
leaving the brain malnourished.
Myth: Most people use only 10
percent of their brain.
Reality: A quote from William James that's been
mangled, misinterpreted, and misused may explain the myth's
origins. In making a general point about human potential,
the philosophical psychologist said that people "make
use of a very small portion of their possible consciousness,
and of their soul's resources in general." Anecdotal
evidence of individuals suffering physical damage to the
brain and continuing to function, such as the famous story
of Phineas Gage, may also have contributed over the years.
Thanks to the development of neuroimaging technologies—machines
that allow us to view not only structures but functions
of the brain at work—this myth is handily debunked.
While we may not use all of our brain all of time, multiple
areas are simultaneously recruited for every task we undertake.
For example, all the different parts of the brain responsible
for vision, sensation, planning, motor coordination, muscle
activity, and homeostasis are required to play a game
of tennis or write words on a page. In fact, new studies
examining the brain at rest reveal that an entire network
of regions is active even when a person is "doing
nothing," notes Molnar-Szakacs.

Yoga
Statue of Shiva performing Yogic meditation in the
Padmasana posture.
Statue of Tirthankara Parsva performing Yogic meditation
in the Padmasana posture. Yoga (Sanskrit, P?li: ???
yóga) refers to traditional physical and mental
disciplines originating in India.[1] The word is associated
with meditative practices in Indian religions like Buddhism,
Hinduism and Jainism. In Hinduism, it also refers to
one of the six orthodox (?stika) schools of Hindu philosophy,
and to the goal toward which that school directs its
practices. In Jainism it refers to the sum total of
all activities—mental, verbal and physical. Major
branches of yoga in Hindu philosophy include Raja Yoga,
Karma Yoga, Jnana Yoga, Bhakti Yoga, and Hatha Yoga.
Raja Yoga, compiled in the Yoga Sutras of Patanjali,
and known simply as yoga in the context of Hindu philosophy,
is part of the Samkhya tradition. Many other Hindu texts
discuss aspects of yoga, including Upanishads, the Bhagavad
Gita, the Hatha Yoga Pradipika, the Shiva Samhita and
various Tantras. The Sanskrit word yoga has many meanings,
and is derived from the Sanskrit root yuj, meaning "to
control", "to yoke" or "to unite"
Translations include "joining", "uniting",
"union", "conjunction", and "means".
Outside India, the term yoga is typically associated
with Hatha Yoga and its asanas
(postures) or as a form of exercise. Someone who practices
yoga or follows the yoga philosophy is called a Yogi
Guide: If you want to try a trendy exercise these days,
why not have a go at yoga. You will be in the company
of host of celebrity converts who may be seen curling
up in pretzel-like positions - Madonna, Sting, and Geri
Halliwell leading the ranks. Yoga has experienced such
a surge in popularity that certain classes are now so
crammed with mats that it can be hard to do a basic
sun salutation without head-butting a fellow practitioner.

Pilates
Pilates (pronounced /p??l??ti?z/) is a physical fitness
system developed in the early 20th century by Joseph Pilates
in Germany.[1] As of 2005 there are 11 million people
who practice the discipline regularly and 14,000 instructors
in the United States.
Pilates called his method Contrology (from control and
Greek -?????, -logia), because he believed his method
uses the mind to control the muscles. The program focuses
on the core postural muscles which help keep the body
balanced and which are essential to providing support
for the spine. In particular, Pilates exercises teach
awareness of breath and alignment of the spine, and aim
to strengthen the deep torso muscles.
Guide: Pilates (pronounced: puh-lah-teez) improves
your mental and physical well-being, increases flexibility,
and strengthens muscles. Pilates uses controlled movements
in the form of mat exercises or equipment to tone and
strengthen the body. For decades, it's been the exercise
of choice for dancers and gymnasts (and now Hollywood
actors), but it was originally used to rehabilitate
bedridden or immobile patients during World War I.
Pilates is designed to strengthen the body's core by
developing pelvic stability and abdominal control. The
body will redevelop its natural foundation, which is
often hindered by poor posture and motor control issues
resulting from modern day living, injury, illness or
heredity. This concentration of work within the core
(abdominals, lower back, and hip
musculature) results in more fluid, efficient movements.
Pilates builds co-ordination, strength and improves
flexibility and joint mobility through slow, controlled
movements and proper breathing. By combining elements
of yoga, breath work, weight training and gymnastics,
Pilates is a truly holistic form of exercise, producing
amazing results.

Hiking
Hiking is an outdoor activity which consists of walking
in natural environments, often on hiking trails. It is
such a popular activity that there are numerous hiking
organizations worldwide. The health benefits of different
types of hiking have been confirmed in studies. The word
hiking is understood in all English-speaking countries,
but there are differences in usage.
Guides:
Go Early: One key to
a successful long and satisfying day hike is to start
in the night. (Hey, DayHiker) I thought you said it
was a "day" hike?
Lose some sleep. Deal with it. It’s OK. Think
about it. Would you rather start out in the dark or
end in the dark. You can always sleep after the hike
is over. Getting on the trail at 3 or 4 in the morning
sounds extreme, but it really makes sense. High altitude
hikes can be prone to afternoon thunderstorms. It’s
much better to reach the summit by 10-11am and be
well on the way back down during vulnerable afternoon
hours. Another
benefit of heading out at or before dawn is cooler weather.
Less heat means less sweating, therefore less water
needed and a lighter load.
One of the classic "day" hikes begins around
midnight ascending Mt Whitney to watch the sunrise.
Hiking on a trail at night during a full moon is an
adventure everyone should experience. A flashlight is
hardly needed. Go Light: It’s simple: carry less,
go further. A minimalist approach is suggested to food,
clothing, and other items. Each hike should be planned
considering the risks involved. One advantage to extreme
day hiking on well-established trails is the reduced
need for survival items since its harder to get lost
or hurt yourself.
No one is suggesting you should not bring your single
lens reflex camera with tripod, arctic parka for that
summer blizzard, first aid kit capable of heart bypass
surgery, enough food to feed everyone on the trail,
and enough rain gear for the 100 year flood. However,
every pound you carry will decrease the probability
of your success. Of course, the tricky part is, the
extra one pound you do carry could save your life.
Go Fast: Actually don’t
go fast. The goal is to minimize time on the trail by
developing a consistent pace with a minimum of rest
stops. One can usually spot a novice hiker by bursts
of speed, followed by many rest stops. The net effect
is usually a slower trip.
Go Far and Go High:
Early+Light+Fast enables one to go Far+High in one day
and return to the creature comforts of a roof and indoor
plumbing. A marathon-like distance with large elevation
changes are made possible by this thinking. The personal
challenge is to go as far and high as you can ... what
someone else does is not the point.
Food: Trail Mix may
not be the best food on the trail for a hike that has
high levels of aerobic and anaerobic exercise. Nuts
and other oily, fatty foods are harder to digest when
your body is using your oxygen elsewhere.
Also, fruit in excess can cause digestive distress.
DayHiker has found the best foods on the trail are sport
bars like Clif Bar, Promax, Balance Bar, etc ... and,
for a sandwich that travels well and always seems to
taste
good: PB&J. Please post your favorite trail food
on the DayHiker forum.
Water: By studying the
weather, the water sources, the trail, one can carry
the minimum amount of water, which is probably the heaviest
thing one carries on a day hike. An interesting idea
is to stash water bottles on the way up, to be retrieved
on the way down. A water filter may be an efficient
way to go to minimize weight of carried water. The disadvantage
is the time it takes to find water, stop and pump.
Clothing: If you have
cotton or wool clothes don’t even think about
hiking with them. Burn them, or give them to homeless
street people who are cold and don’t move fast.
This may be tax deductible. Consult your tax attorney.
There are many high tech fibers that wick (transport
your sweat into the
air) and are warm (since not wet it feels warmer) and
are incredibly light. Some of these trademarked fibers
are coolmax, utralight mircrofeece, microfiber (microprocessors
in these?), capilene, polartec, ultrawick, tactel, spandex,
supplex, gortex, and lycra. By layering these materials
it is possible to hike with incredibly light clothing,
even in freezing weather. Try it. It works. There is
a company, GoLite, that has adopted Jardines philosophy
about light weight hiking.
Check them both out.
Hats: This is easy.
Wear the largest, lightest brim hat you can stomach.
Yes, it’s dorky looking but do it anyway. It keeps
you cooler and lessens the chance for wrinkles and skin
cancer.
Sunscreen: See the
part of the last sentence on hats. High altitude and
summer time are brutal to the skin. Low altitude and
any sun are brutal to the skin. Put sunscreen on all
days, cloudy or not. Consult your local dermatologist.
Shoes: The success
or failure of an extreme day hike is tied to shoe selection.
Heavy, stiff hiking boots are at a decided disadvantage
to a light, flexible, comfortable shoe. Every pound
of shoe is equivalent to carrying 7-9 pounds on your
back. Minimize shoe weight by selecting a cross-trainer
with ankle support, a trail-running shoe, or one of
the
lighter hiking shoes that are readily available.
When you go to buy a "hiking" shoe you will
almost always be encouraged to buy one with "great
ankle support" and a steel shank so you won’t
"feel the rocks." This makes sense if you
are carrying a 60 pounds pack and are going through
scree (small rocks) and other rugged cross-country terrain.
This also makes sense if you are the shoe salesman trying
to make a $225 sale as opposed to a $85 lighter shoe.
If you are hiking on a trail these are not a priority.
Go for comfort and the cheaper price. "But I have
weak ankles," is the lament. Fine: see Trekking
Poles article. DayHiker suggests walking on a very hard
surface with a full hiking boot for a whole day is not
comfortable for a lot of people. The bottoms of your
feet are in pain and blisters are usually not far behind.
Comfort rules on a trail.
Regarding weak ankles - Consult your physician first,
then consider this
possibility: Rigorous exercise may correct your perceived
impediment.
Light jogging down hill or over a dry river bed full
of smooth rocks may be just what the doctor ordered
to get those ankles in shape.
Socks: It’s amazing how important sock selection
is when engaged in an
long day hike of many hours. The coarse threads of hiking
socks will
eventually begin to dig into your skin causing much
discomfort and blisters. Avoid this by wearing a thin
nylon sock, a liner, as a first layer, or just on pair
of light ones. Bring an extra pair for replacement half
way. There is something really refreshing about putting
on a pair of socks half-way through a killer hike. One
more thought: Before undertaking that marathon hike
consider this - new socks, old shoes. It's not a good
time to see if those new shoes work.
Trekking Poles: This
is the best-kept secret for success on the extreme day
hike. Common in Europe, and mandatory equipment for
mountain climbers, trekking poles give an advantage,
which most people don’t understand until they
try them. The uninformed usually comment or think, "Where’s
the snow?" "Aren’t they heavy?"
"Do they help? "Are you really a wimp?"
It is estimated the use of trekking poles can add up
to 20% efficiency to the body by transferring some of
the load to your arms. Even more significant is the
stability the poles provide, greatly reducing the need
for leg muscles to continually provide balance. The
chances of a sprained or broken ankle, the bane of a
hiker a long way from help, is greatly reduced by the
use of poles. Stream crossings, wet rocks or logs, ice,
loose rocks, and steep areas are made safer. Using a
very light shoe that does not have much ankle support
is made possible with poles.
A single walking stick is better than nothing, but is
more awkward than two lightweight trekking poles. Additionally,
telescoping poles can be stowed in your daypack at times
when they are not needed. Some models have shock absorbers
built in which allows less stress on the wrists when
stroking hard with the poles. Another feature is a slight
taper on the hand grips which make for a more ergonomical
grasp.
Turn Around Time: A
carefully planned long day trip must have an estimated
time that you stop and go back to civilization no matter
what. Since you have no overnight equipment, food and
water are minimal, and you are dressed lightly, it’s
imperative to stick to a deadline for reaching your
goal. In most cases you should be on your way back by
noon, at the latest- especially when at high altitudes
and/or when thunderstorms are probable.
If you don't do this, you might be the subject of a
newspaper article chronicling the pros and cons of your
survival techniques.

Body Fat Percentage
As recommended, try to manage body fat as a regular mind
maintenance to avoid those extra inches.
A person's total body fat percentage is the total weight
of the person's fat divided by the person's weight and
reflects both essential fat and storage fat. Essential
fat is that amount necessary for maintenance of life
and reproductive functions. The percentage for women
is greater than that for men, due to the demands of
childbearing and other hormonal functions. Essential
fat is 2–5% in men, and 10–13% in women.
Storage fat consists of fat accumulation in adipose
tissue, part of which protects internal organs in the
chest and abdomen. The minimum recommended total body
fat percentage exceeds the essential fat percentage
value reported above. A number of online tools are available
for calculating estimated body fat percentage.

Don’t Forget The Warm Up and Cooling Down Process
Appropriate warm-up and cool-down periods are an important
part of any exercise programme that aims to develop
and maintain fitness.
THE WARM-UP
Why warm up?
A pre-exercise warm-up:
• warms your muscles by increasing the movement
of blood through your tissues, making the muscles more
supple;
• increases delivery of oxygen and nutrients to
your muscles by increasing the blood flow to them;
• prepares your muscles for stretching;
• prepares your heart for an increase in activity;
• prepares you mentally for the upcoming exercise;
and
• primes your nerve-to-muscle pathways to be ready
for exercise.
The warm-up is widely viewed as a simple measure to
help prevent injury during exercise. While scientific
studies are ongoing to define the best warm-up techniques
to gain this injury-prevention advantage, the warm-up
in general is firmly established as a key to exercising
safely and effectively.
Ensuring an effective warm
up
To make your warm up effective, you need to do movements
that increase your heart rate and breathing, and slightly
increase the temperature of your muscle tissue. A good
indication is warming up to the point where you have
raised a light sweat.
If you’re exercising for general fitness, allow
5 to 10 minutes for your pre-exercise warm-up (or slightly
longer in cold weather).
If you are exercising at a higher level than for general
fitness, or have a particular sporting goal in mind,
you may need a longer warm-up, and one that is designed
specifically for your sport.
Warm-up options
Follow these options in the order listed.
1. General warm-up. To begin your warm-up do 5 minutes
of light (low intensity) physical activity such as walking,
jogging on the spot or on a trampoline. Pump your arms
or make large but controlled circular movements with
your arms to help warm the muscles of your upper body.
2. Sport-specific warm-up. One of the best ways to warm
up is to perform the upcoming exercise at a slow pace.
This will allow you to simulate at low intensity the
movements you are about to perform at higher intensity
during your chosen activity. Examples include a few
minutes of easy catching practice for cricketers or
baseball players, going through the motion of bowling
a ball for lawn bowlers, shoulder rolls, side-stepping
and slow-paced practice hits for tennis players, or
jogging for runners. Sport-specific warm-ups are often
designed by a qualified trainer in that sport.
3. Stretching. Any stretching is best performed after
your muscles are warm, so only stretch after your general
warm-up. Stretching muscles when they are cold may lead
to a tear. Static stretching (stretching a muscle and
holding it in this position without discomfort for 10-30
seconds) is considered the safest method of stretching.
Perform a light static stretching routine at the end
of your warm up by stretching each of the muscle groups
you will be using in your chosen activity. A static
stretch should be held at the point where you can feel
the stretch but do not experience any discomfort. If
you feel discomfort, ease back on the stretch. Remember
not to bounce when holding the stretch. Don’t
spend so long doing your stretches that your muscles
cool down and your heart rate returns to normal. It
is better to keep most of your static stretching for
after your exercise session, that is, after your cool-down.
Recent studies comparing a warm-up that includes static
stretching with a warm-up that does not include static
stretching have shown that, although pre-exercise static
stretching does improve flexibility, it does not appear
to prevent injury during exercise.
Apart from static stretching, other methods of stretching
include ballistic, dynamic and PNF (proprioceptive neuromuscular
facilitation) stretching, each of which is best done
under instruction from a qualified fitness instructor
or sports coach.
THE COOL-DOWN
Why cool down?
The practice of cooling down after exercise means slowing
down your level of activity gradually. Cooling down:
• helps your heart rate and breathing to return
towards normal gradually;
• helps avoid fainting or dizziness, which can
result from blood pooling in the large muscles of the
legs when vigorous activity is stopped suddenly;
• helps prepare your muscles for the next exercise
session, whether it's the next day or in a few days'
time; and
• helps to remove waste products from your muscles,
such as lactic acid, which can build up during vigorous
activity.
You may see conflicting advice as to whether cooling
down prevents post-exercise muscle soreness, also known
as delayed-onset muscle soreness (DOMS). However, even
if cooling down doesn’t prevent DOMS, the other
benefits of cooling down mean that you should always
make it a part of your exercise session.
Ensuring an effective cool-down
For an effective cool-down:
• perform low intensity exercise for a minimum
of 5 to 10 minutes; and
• follow this with a stretching routine.
Cool-down options
1. Continuing your chosen exercise while gradually slowing
its intensity. Gradually slowing down the pace and exertion
of your activity over several minutes can seem a natural
progression, as well as fulfilling the need to include
a cool-down period at the end of your exercise.
2. Slow jogging or brisk walking. Another option is
to jog or walk briskly for a few minutes after your
exercise,
making sure that this activity is lower in intensity
than the exercise you have just performed.
Stretching after your cool-down
The best time to stretch is after your cool-down, as
at this time your muscles are still warm and most likely
to respond favourably and there is a low risk of injury.
Stretching helps to relax your muscles and restore them
to their resting length, and improve flexibility (the
range of movement about your joints).
As a guide, allow 10 minutes of post-exercise stretching
for every one hour of exercise. Make these post-exercise
stretches more thorough than your pre-exercise stretches.
Ensure that you stretch all the major muscle groups
that you have used during your exercise. Stretch each
muscle group for 20 to 30 seconds, 2 to 3 times.

Hair Scares
Excessive hair shedding
Each individual strand of hair has its own cycle, growing
for six to eight years, resting for a few months, and
then shedding. "About 10 percent of your hair is
shedding at any one given time," Mirmirani says,
pointing out that many things can interrupt the cycle
and cause more hairs to shed earlier, including stress,
fever, weight loss (even 10 pounds) or low iron levels.
If you're noticing more shedding than usual, examine your
lifestyle to see what might have changed or consult your
dermatologist for tests.

Supplemental Knowledge
It seems impossible to turn around these days without another
"expert" prodding us to get enough Calcium or
Vitamin C. And, we've all seen the commercials that espouse
the need to enhance our daily diets with a supplement or
multi-vitamin that promises to do everything from strengthen
our bones to protect us from cancer. So, here's a guide
that sorts through all of the hype and gives you the 10
must-have minerals and vitamins that promote healthy living. |

How to Sleep Better
'Sleep Hygiene' Solutions for Better Sleep
By Michael J. Breus, PhD
From having occasional difficulty sleeping to insomnia,
there is a lot you can do to get a better night's sleep,
feel refreshed when you awake, and remain alert throughout
the day. It's called "sleep hygiene" and refers
to those practices, habits, and environmental factors that
are critically important for sound sleep. And most of it
is under your control. There are four general areas important
to sleep hygiene:
• Our circadian rhythm, or 24-hour cycle
• Aging
• Psychological stressors -- those factors can cause
difficulty falling asleep and disturb the quality of your
sleep
• Common social or recreational drugs like nicotine,
caffeine, and alcohol
Circadian Rhythm
We all have a day-night cycle of about 24 hours called
the circadian rhythm. It greatly influences when we sleep
and the quantity and the quality of our sleep. The more
stable and consistent our circadian rhythm is, the better
our sleep. This cycle may be altered by the timing of
various factors, including naps, bedtime, exercise, and
especially exposure to light (from traveling across time
zones to staring at that laptop in bed at night). Aging
Aging also plays a role in sleep and sleep hygiene. After
the age of 40 our sleep patterns change, and we have many
more nocturnal awakenings than in our younger years. These
awakenings not only directly affect the quality of our
sleep, but they also interact with any other condition
that may cause arousals or awakenings, like the withdrawal
syndrome that occurs after drinking alcohol close to bedtime.
The more awakenings we have at night, the more likely
we will awaken feeling unrefreshed and unrestored. Psychological
Stressors
Psychological stressors like deadlines, exams, marital
conflict, and job crises may prevent us from falling asleep
or wake us from sleep throughout the night. It takes time
to "turn off" all the noise from the day. No
way around it. If you work right up to the time you turn
out the lights, or are reviewing all the day's events
and planning tomorrow (sound familiar?), you simply cannot
just "flip a switch" and drop off to a blissful
night's sleep.
One must develop some kind of pre-sleep ritual to break
the connection between all the stress and bedtime. This
is perhaps even more important for children. These rituals
can be as short as 10 minutes or as long as an hour. Some
find relief in making a list of all the stressors of the
day, along with a plan to deal with them, as it serves
to end the day. Combining this with a period of relaxation,
perhaps by reading something light, meditating, or taking
a hot bath can also help you get better sleep. And don't
look at that clock! That tick-tock will tick you off.
Social or Recreational Drugs Social or recreational drugs
like caffeine, nicotine, and alcohol may have a larger
impact on your sleep than you realize. Caffeine, which
can stay in your system as long as 14 hours, increases
the number of times you awaken at night and decreases
the total amount of sleep time. This may subsequently
affect daytime anxiety and performance. The effects of
nicotine are similar to those of caffeine, with a difference
being that at low doses, nicotine tends to act as a sedative,
while at high doses it causes arousals during sleep. Alcohol
may initially sedate you, making it easier to fall asleep;
however, as it is metabolized and cleared from your system
during sleep, it causes arousals that can last as long
as two to three hours after it has been eliminated. These
arousals disturb sleep, often causing intense dreaming,
sweating, and headache. Smoking while drinking caffeine
and alcohol can interact to affect your sleep dramatically.
These sleep disturbances may be most apparent upon awakening,
feeling unrefreshed, groggy, or hungover. It is important
to realize that not getting the proper amount of and the
best quality sleep may have serious short-term and long-term
consequences. Many studies have shown that sleep deprivation
adversely affects performance and alertness. Reducing
sleep by as little as one and a half hours for just one
night reduces daytime alertness by about one-third. Excessive
daytime sleepiness impairs memory and the ability to think
and process information, and carries a substantially increased
risk of sustaining an occupational injury. Long-term sleep
deprivation from sleep disorders like apnea have recently
been implicated in high blood pressure, heart attack,
and stroke. All that said, here are some sleep hygiene
tips to help you relax, fall asleep, stay asleep, and
get better sleep so that you wake up refreshed and alert.
1. Avoid watching TV, eating, and discussing emotional
issues in bed. The bed should be used for sleep and sex
only. If not, we can associate the bed with other activities
and it often becomes difficult to fall asleep.
2. Minimize noise, light, and temperature extremes during
sleep with ear plugs, window blinds, or an electric blanket
or air conditioner. Even the slightest nighttime noises
or luminescent lights can disrupt the quality of your
sleep. Try to keep your bedroom at a comfortable temperature
-- not too hot (above 75 degrees) or too cold (below 54
degrees).
3. Try not to drink fluids after 8 p.m. This may reduce
awakenings due to urination.
4. Avoid naps, but if you do nap, make it no more than
about 25 minutes about eight hours after you awake. But
if you have problems falling asleep, then no naps for
you.
5. Do not expose your self to bright light if you need
to get up at night. Use a small night-light instead.
6. Nicotine is a stimulant and should be avoided particularly
near bedtime and upon night awakenings. Having a smoke
before bed, although it may feel relaxing, is actually
putting a stimulant into your bloodstream.
7. Caffeine is also a stimulant and is present in coffee
(100-200 mg), soda (50-75 mg), tea (50-75 mg), and various
over-the-counter medications. Caffeine should be discontinued
at least four to six hours before bedtime. If you consume
large amounts of caffeine and you cut your self off too
quickly, beware; you may get headaches that could keep
you awake.
8. Although alcohol is a depressant and may help you fall
asleep, the subsequent metabolism that clears it from
your body when you are sleeping causes a withdrawal syndrome.
This withdrawal causes awakenings and is often associated
with nightmares and sweats.
9. A light snack may be sleep-inducing, but a heavy meal
too close to bedtime interferes with sleep. Stay away
from protein and stick to carbohydrates or dairy products.
Milk contains the amino acid L-tryptophan, which has been
shown in research to help people go to sleep. So milk
and cookies or crackers (without chocolate) may be useful
and taste good as well.
10. Do not exercise vigorously just before bed, if you
are the type of person who is aroused by exercise. If
this is the case, it may be best to exercise in the morning
or afternoon (preferably an aerobic workout, like running
or walking).
11. Does your pet sleep with you? This, too, may cause
arousals from either allergies or their movements in the
bed. Thus, Fido and Kitty may be better off on the floor
than on your sheets.
Good sleep hygiene can have a tremendous impact upon getting
better sleep. You should wake-up feeling refreshed and
alert, and you should generally not feel sleepy during
the day. If this is not the case, poor sleep hygiene may
be the culprit, but it is very important to consider that
you may have an unrecognized sleep disorder. Many, many
sleep disorders go unrecognized for years, leading to
unnecessary suffering, poor quality of life, accidents,
and great expense. Since it is clear how critical sound
sleep is to your health and well-being, if you are not
sleeping well, see your doctor or a sleep specialist.
