HEALTH
Mental Benefits of Working Out
A regular regimen can improve more than just the body
ALLY ACKOUREY
HEALTH EDITOR
For years exercising has been regarded as the number one way to lose weight and keep it off. However, exercise not only has the obvious benefits to the body, but also
many other relatively unknown effects that reduce stress
and can contribute to overall mental and physical health.
Exercise can improve one’s mood and often reduces
stress and depression. This is mostly attributed to the release of endorphins, norepinephrine, dopamine, and seratonin which are produced in the brain during long, continuous periods of exercise. All four substances are natural
neurotransmitters; endorphins and dopamine are opiates.
The stimulation provided by these chemicals can
have a relaxing effect that also leaves one feeling happier
than before. Hence, the more exercise the body gets, the
better a person looks and feels, leading to higher self-esteem and reduced stress and anxiety.
Obviously exercising helps manage weight by burning calories, but it can also prevent chronic diseases. According to MayoClinic.com, exercise can contribute to the
prevention and management of high blood pressure, as
well as increasing “good” cholesterol while lowering the
“bad.”
Exercise can also strengthen the heart and lungs by
delivering oxygen and nutrients to the tissues and causing blood circulation to be more efficient, leaving the body
feeling energized. In addition to having more energy to
get through a busy schedule and do more things one enjoys, this can prevent heart disease.

How

More
Exercise
It is common knowledge that exercise means
burning calories, and that more exercise burns more
calories. Exercise not only helps one lose weight but
also improves mood. When a person feels better, he
or she looks better.
Here are a few simple ways to fit some extra
physical activity into a busy schedule, with no major lifestyle change:
1. Sure that elevator might be tempting, but taking
the stairs is an easy way to burn off a few of those
unwanted calories.
2. Grab either a friend or a dog and take a walk. A
20 minute walk every day can make that cookie disappear!
3. Not ready to give up that valuable TV time? Try
doing jumping jacks during commercials.
4. Go back to those elementary school days and
jump rope outside for as long as possible. Not only
will jumping rope burn calories, but getting fresh air
will also improve your mood.
5. As if anyone needed another reason to take a trip
to the mall, walking briskly around the shopping
center for a few hours burns hundreds of calories.
6. As daunting a task as it may seem, washing your
own car burns a lot more calories than having someone else do it.

Teenagers and adults often turn to fad diets to lose
about five to ten pounds in the first few weeks, eliminating
all of the calorie supply and most of their energy source,
which increases appetite and causes immune difficulties.
As soon as old eating habits return, weight is gained
more quickly and it is possible to actually gain more
weight than was lost. Because people often come together
to eat at social gatherings such as restaurants and religious
dinners, one may develop a sense of alienation from close
family and friends or simply ‘non dieters,’ as well as an
unhappy relationship with dietary foods.
Eventually cravings become unstoppable, and most
dieters start cheating on their diets by consuming the ‘Forbidden Foods.’ While the cheats are small, one may still
continue to lose some weight, though it will take longer as
the immune system weakens and the cravings increase.
No exercise while on a diet can cause the loss of lean
muscle mass, water and essential fats. Lost muscle slows
down metabolism and prolongs the diet as the body burns
fewer calories per day just to keep the body functioning.
Since the metabolism (energy) is slowed it takes a conscious effort to exercise while dieting. Also, losing weight
at a very rapid rate may increase the risk for developing
gallstones (clusters of solid material in the gallbladder).
Daily exercise improves appearance and health altogether. Clients of Bariatric (fat removal) surgery clinics are
prescribed an hour of exercise a day before they can undergo surgery. Some lose large amount of weight and decide to skip the surgery after all.
Research suggests that losing one half to two pounds
each week by eating moderate portions, and exercising
daily is the best way to lose weight and keep it off.
A reduced-calorie eating plan that includes carbohydrate, protein, and fat will also allow you to lose weight
without missing out on the key nutrients, such as: whole
grains, fruits, and vegetables.
Eating fewer than 130 grams of carbohydrates a day
can lead to the buildup of Ketones (partially broken-down
fats) in the blood, which is a risk factor for gout (a swelling of the joints) and kidney stones because of the production of uric acid.
Many diets use natural ingredients and herbal products that are as natural food supplements, yet these products are mostly not scientifically tested to prove safety.
For example, herbal products containing ephedrine have
caused serious health problems and even death.
When dieting to look better on a TV show, they may
be an appropriate solution, but if the plan is to lose twenty
pounds or more, you are better off eliminating foods step
by step and still consuming enough to gain muscle.
According to the American Heart Association,
73,000,000 Americans live with heart disease. That exercise can prevent one less American from suffering a very
life threatening condition should be motivation enough to
attempt to get at least a little more exercise every day.
Another motivating benefit of daily exercise is that
it can promote better sleep, which, from experience, is a
very important aspect of any high school student’s – or
anyone’s, for that matter – life and well-being. It can help a
person fall asleep faster and sleep deeper, improving concentration, productivity, and mood.
Since results are best seen after exercising in the afternoon, no significant change is necessary in a student’s
busy lifestyle since the majority of classes end before three
pm. Just think – a little sweat can help bring not only refreshing sleep, but also acts as a natural stimulant to the
brain, providing motivation to work harder and apply
oneself to everyday tasks.
So how much is enough? According to the American Heart Association and the American College of Sports
Medicine, healthy individuals under 65 years of age
should get at least 30 minutes of moderate-intensity aerobic activity five days a week, or at least 20 minutes of highintensity aerobic activity three days a week.
Examples of moderate-intensity activities include
brisk walking and swimming, while exercises like running and bicycling is considered high-intensity.
So whether one chooses to go on a run a few times
a week, or to swim every day, he or she is bound to reap
from the multitude of benefits exercise provides, both
physically and mentally.
