Yoga
is among the oldest known systems of health practiced in the world
today, and research into yoga practices has had a strong impact
on the fields of stress reduction, mind/body medicine and energy
medicine. They physical postures, breathing exercises, and meditation
practices of yoga have been proven to reduce stress, lower blood
pressure, regulate heart rate, and even retard the ageing process.
Uses
The age-old
set of exercises known in the West as 'yoga' offers a significant
variety of proven health benefits. It increases the efficiency of
the heart and slows the respiratory rate, improves fitness, lower
blood pressure, promotes relaxation, reduces stress and allays anxiety.
It also serves to improve coordination, posture, flexibility, range
of motion, concentration, sleep, and digestion. It can be used as
supplementary therapy for conditions as diverse as cancer, diabetes,
arthritis, asthma, migraine and AIDS, and helps to combat addictions
such as smoking. It is not, in itself, a cure for any medical ailment.
But as part of the well-known Dean Ornish programme of diet and
exercise, it has contributed to the reversal of heart disease.
Procedure
of Treatment
Yoga exercises
are usually conducted in group classes, although private instruction
is also available in many areas. You should wear loose, comfortable
clothing to the class, and you should bring a 'sticky' mat
with you to prevent slipping during the exercises. No equipment
needed, although advanced students often use a strap to assist in
leg stretches. Wall-mounted devices sometimes available to help
you maintain balance during difficult exercises. The exercises are
almost always performed in bare feet. A typical session includes
three disciplines: breathing exercises, body postures, and meditation.
You may also be given advice on nutrition and lifestyle. Many proponents
feel morning is the best time to practice yoga, but classes are
offered throughout the day and evening. It is advisable to avoid
eating for one hour before class. Each session usually begins with
a set of gentle warm-up exercises. The teacher will then ask you
to focus on your breathing, and may take you through several breathing
exercises. At the very least, you will be asked to breathe through
your nose, evenly through both nostrils. Then it is on to the yoga
postures, a series of poses that typically must be held for periods
of a few seconds to several minutes. Unlike the routine in calisthenics
or weight training, you will not be asked to repeat postures more
than three times, and some will be done only once. Some of the postures,
such as shoulder rolls or neck stretches, will probably be familiar
or even contorted. Despite the difficulty of such postures, however,
contortion for its own sake is never the point. Instead, the goal
is to mildly stretch all the muscle groups in the body, while gently
squeezing the internal organs. To balance the muscle groups, the
postures follow a specific order. As you assume the various postures,
you will be asked to move gently, without jerking or bouncing. Breathing
techniques remain important. You will need to focus on exhaling
during certain movements and inhaling during others. Likewise, as
you hold certain postures, you may be instructed to inhale through
one nostril and exhale through the other. You will be allowed to
rest after every three or four postures, and at the conclusion of
the exercises, there is usually a period of rest or meditation.
You should remain comfortable throughout the session, and should
leave with both body and mind relaxed.
Treatment Time: Classes usually last 45 minutes to an hour,
but experts stress that even short sessions can be beneficial if
you make them a regular routine.
Treatment Frequency: Classes may be taken once a week, or
more often, as desired. Your teacher will probably ask you to practice
new positions at home, and will encourage you to run through at
least a portion of the yoga routine each day. Regular practice,
even if brief, is recommended for the best results.
Benefits
Although the
yoga we know today is practiced mainly for its health benefits,
it is rooted in Hindu religious principles some 5,000 years old.
Derived from the Sanskrit word for 'union', the term yoga
refers to far more than exercise. In fact, it encompasses a variety
of disciplines designed to ultimately bring its practitioners closer
to God. Dynana yoga, for instance, seeks union through meditation,
while jnana yoga entails the study of scriptures and karma
yoga calls for selfless service to God and mankind. The exercises
we now call simply 'yoga' are actually hatha yoga,
a discipline intended to prepare the body for the pursuit of union
with the divine while raising the practitioner's awareness of creation
to a higher, keener state. Through controlled breathing, prescribed
postures (called asanas), and meditation, hatha yoga
seeks to enhance the prana, or life force, that resides in
the body and achieve a state of balance and harmony between body
and mind. Each of these three disciplines contributes to the search
for union in its own unique way.
Breathing: The life force prana is believed to enter the
body through the breath, and much of hatha yoga is concerned with
helping you control your breathing properly. Shallow, hurried breathing
is believed to inhibit the life force, and affect mind and body
adversely. Deep, slow breathing is encouraged.
Postures: Some yoga postures are intended to stretch and
strengthen muscles, others to improve posture and work the skeletal
system, while still others aim to compress and relax the organs
and nerves. The underlying purpose is to perfect the body, making
it a worthy host for the soul.
Meditation: Meditation supplements and reinforces the disciplines
of hatha yoga, focusing the mind and relaxing the body. Closely
linked with focused breathing, it aims to produce a quiet, calm
frame of mind. Many people find that it reduces stress and increases
energy. The interplay of this and the other two facets of hatha
yoga, and the quiet, considered repetition of each, is considered
key to achieving yoga's benefits. Despite its use of physical exercises,
yoga is perhaps most closely related to the mind-body family of
therapies, which includes meditation and biofeedback. Research shows
that, like other mind-body practices, yoga produces measurable physiological
changes in the body, including a decrease in the respiratory rate
and blood pressure, and an alteration in brainwave activity reflecting
increased relaxation. Yoga has been shown to reduce stress and anxiety,
both immediately and over time, and is often recommended to relive
the pain and anxiety of chronic illness. When practiced regularly,
it promotes relaxation and enhances the sense of wellbeing. It also
improves physical fitness and circulation, and some advocates say
it improves memory. When combined with a low-fat diet and moderate
aerobic exercise, it has been found to reverse the build-up of plaque
in the coronary arteries-and the more it is practiced, the greater
the improvement. Although yoga's effects are unquestionable, scientists
still do not know exactly how it produces them. Some speculate that,
like other mind-body therapies, it works largely by relieving stress.
Others suggest that it promotes the release of endorphins, the brain's
natural painkillers. The Office of Alternative Medicine at the National
Institutes of Health has several studies underway to clarify the
matter. In the meantime, yoga continues to be practiced by some
six million people in the United States.
Who Should
Avoid This Therapy?
Avoid yoga completely
if you have had a recent back injury or surgery. Check with your
doctor first if you have arthritis, a slipped disk, heart disease,
or high blood pressure. (Although yoga tends to relieve high blood
pressure, certain postures must be avoided. Be sure to alert your
instructor to the problem if you decide to proceed.) Although some
postures are not recommended during pregnancy, special classes are
available for expectant mothers. Some experts also warn against
strenuous postures during menstruation, and when you are ill with
a cold or infection.
Side-effects
At the outset,
you may suffer some stiffness while your body adapts to the postures.
When done properly, however, yoga is not stressful or tiring, and
any stiffness should be short-lived and minor.
