Definition
The term yoga comes from a Sanskrit word that
means yoke or union. Traditionally, yoga is a method
joining the individual self with the Divine, Universal
Spirit, or Cosmic Consciousness. Physical and mental
exercises are designed to help achieve this goal, also
called self-transcendence or enlightenment. On the physical
level, yoga postures, called asanas, are designed to
tone, strengthen, and align the body. These postures are
performed to make the spine supple and healthy and to
promote blood flow to all the organs, glands, and tissues,
keeping all the bodily systems healthy. On the mental
level, yoga uses breathing techniques (pranayama) and
meditation (dyana) to quiet, clarify, and discipline the
mind. However, experts are quick to point out that yoga
is not a religion, but a way of living with health and
peace of mind as its aims.
Origins
Yoga originated in ancient India and is one of the
longest surviving philosophical systems in the world.
Some scholars have estimated that yoga is as old as
5,000 years; artifacts detailing yoga postures have been
found in India from over 3000 B.C.Yoga masters (yogis)
claim that it is a highly developed science of healthy living
that has been tested and perfected for all these years.
Yoga was first brought to America in the late 1800s
when Swami Vivekananda, an Indian teacher and yogi,
presented a lecture on meditation in Chicago. Yoga slowly
began gaining followers, and flourished during the
1960s when there was a surge of interest in Eastern philosophy.
There has since been a vast exchange of yoga
knowledge in America, with many students going to
India to study and many Indian experts coming here to
teach, resulting in the establishment of a wide variety of
schools. Today, yoga is thriving, and it has become easy
to find teachers and practitioners throughout America. A
recent Roper poll, commissioned by Yoga Journal, found
that 11 million Americans do yoga at least occasionally
and six million perform it regularly. Yoga stretches are
used by physical therapists and professional sports
teams, and the benefits of yoga are being touted by
movie stars and Fortune 500 executives. Many prestigious
schools of medicine have studied and introduced
yoga techniques as proven therapies for illness and
stress. Some medical schools, like UCLA, even offer
yoga classes as part of their physician training program.
Benefits
Yoga has been used to alleviate problems associated
with high blood pressure, high cholesterol, migraine
headaches, asthma, shallow breathing, backaches, constipation,
diabetes, menopause, multiple sclerosis,
varicose veins, and many chronic illnesses. It also has
been studied and approved for its ability to promote relaxation
and reduce stress. On the other hand, some researchers
are now questioning claims that yoga is beneficial
for such conditions as carpal tunnel syndrome.
As of late 2002, yoga is increasingly recommended
for dysmenorrhea, premenstrual syndrome, and other
disorders in premenopausal women, in Europe as well as
in the United States.
Yoga can also provide the same benefits as any welldesigned
exercise program, increasing general health
and stamina, reducing stress, and improving those conditions
brought about by sedentary lifestyles. Yoga has the
added advantage of being a low-impact activity that uses
only gravity as resistance, which makes it an excellent
physical therapy routine; certain yoga postures can be
safely used to strengthen and balance all parts of the
body. A study published in late 2002 summarized recent
findings about the benefits of yoga for the cardiovascular
and musculoskeletal systems. The review noted that
yoga is still viewed as a “trendy” form of exercise rather
than one with documented medical benefits.
Meditation has been much studied and approved for
its benefits in reducing stress-related conditions. The landmark
book, The Relaxation Response, by Harvard cardiologist
Herbert Benson, showed that meditation and breathing
techniques for relaxation could have the opposite effect
of stress, reducing blood pressure and other indicators.
Since then, much research has reiterated the benefits
of meditation for stress reduction and general health. Currently,
the American Medical Association recommends
meditation techniques as a first step before medication for
borderline hypertension cases. Some 2002 studies indicate
that yogic meditation by itself is effective in lowering
serum cholesterol as well as blood pressure.
Modern psychological studies have shown that even
slight facial expressions can cause changes in the involuntary
nervous system; yoga utilizes the mind/body connection.
That is, yoga practice contains the central ideas that
physical posture and alignment can influence a person’s
mood and self-esteem, and also that the mind can be used
to shape and heal the body. Yoga practitioners claim that
the strengthening of mind/body awareness can bring eventual
improvements in all facets of a person’s life.
Description
Classical yoga is separated into eight limbs, each a
part of the complete system for mental, physical, and
spiritual well-being. Four of the limbs deal with mental
and physical exercises designed to bring the mind in
tune with the body. The other four deal with different
stages of meditation. There are six major types of yoga,
all with the same goals of health and harmony but with
varying techniques: hatha, raja, karma, bhakti, jnana,
and tantra yoga. Hatha yoga is the most commonly
practiced branch of yoga in America, and it is a highly
developed system of nearly 200 physical postures,
movements, and breathing techniques designed to tune
the body to its optimal health. The yoga philosophy believes
the breath to be the most important facet of
health, as the breath is the largest source of prana, or
life force, and hatha yoga utilizes pranayama, which literally
means the science or control of breathing. Hatha
yoga was originally developed as a system to make the
body strong and healthy enough to enable mental awareness
and spiritual enlightenment.
There are several different schools of hatha yoga in
America; the two most prevalent ones are Iyengar and
ashtanga yoga. Iyengar yoga was founded by B.K.S.
Iyengar, who is widely considered as one of the great living
innovators of yoga. Iyengar yoga puts strict emphasis
on form and alignment, and uses traditional hatha yoga
techniques in new manners and sequences. Iyengar yoga
can be good for physical therapy because it allows the
use of props like straps and blocks to make it easier for
some people to get into the yoga postures. Ashtanga
yoga can be a more vigorous routine, using a flowing
and dance-like sequence of hatha postures to generate
body heat, which purifies the body through sweating and
deep breathing.
The other types of yoga show some of the remaining
ideas that permeate yoga. Raja yoga strives to bring
about mental clarity and discipline through meditation,
simplicity, and non-attachment to worldly things and desires.
Karma yoga emphasizes charity, service to others,
non-aggression and non-harming as means to awareness
and peace. Bhakti yoga is the path of devotion and love
of God, or Universal Spirit. Jnana yoga is the practice
and development of knowledge and wisdom. Finally,
tantra yoga is the path of self-awareness through religious
rituals, including awareness of sexuality as sacred
and vital.
A typical hatha yoga routine consists of a sequence
of physical poses, or asanas, and the sequence is designed
to work all parts of the body, with particular emphasis
on making the spine supple and healthy and increasing
circulation. Hatha yoga asanas utilize three
basic movements: forward bends, backward bends, and
twisting motions. Each asana is named for a common
thing it resembles, like the sun salutation, cobra, locust,
plough, bow, eagle, and tree, to name a few. Each pose
has steps for entering and exiting it, and each posture requires
proper form and alignment. A pose is held for
some time, depending on its level of difficulty and one’s
strength and stamina, and the practitioner is also usually
aware of when to inhale and exhale at certain points in
each posture, as breathing properly is another fundamental
aspect of yoga. Breathing should be deep and through
the nose. Mental concentration in each position is also
very important, which improves awareness, poise, and
posture. During a yoga routine there is often a position in
which to perform meditation, if deep relaxation is one of
the goals of the sequence.
Yoga routines can take anywhere from 20 minutes to
two or more hours, with one hour being a good time investment
to perform a sequence of postures and a meditation.
Some yoga routines, depending on the teacher
and school, can be as strenuous as the most difficult
workout, and some routines merely stretch and align the
body while the breath and heart rate are kept slow and
steady. Yoga achieves its best results when it is practiced
as a daily discipline, and yoga can be a life-long exercise
routine, offering deeper and more challenging positions
as a practitioner becomes more adept. The basic positions
can increase a person’s strength, flexibility, and
sense of well-being almost immediately, but it can take
years to perfect and deepen them, which is an appealing
and stimulating aspect of yoga for many.
Yoga is usually best learned from a yoga teacher or
physical therapist, but yoga is simple enough that one
can learn the basics from good books on the subject,
which are plentiful. Yoga classes are generally inexpensive,
averaging around 10 dollars per class, and students
can learn basic postures in just a few classes. Many
YMCAs, colleges, and community health organizations
offer beginning yoga classes as well, often for nominal
fees. If yoga is part of a physical therapy program, its
cost can be reimbursed by insurance.
Preparations
Yoga can be performed by those of any age and condition,
although not all poses should be attempted by
everyone. Yoga is also a very accessible form of exercise;
all that is needed is a flat floor surface large enough
to stretch out on, a mat or towel, and enough overhead
space to fully raise the arms. It is a good activity for
those who cannot go to gyms, who do not like other
forms of exercise, or have very busy schedules. Yoga
should be done on an empty stomach, and teachers recommend
waiting three or more hours after meals. Loose
and comfortable clothing should be worn.
Precautions
People with injuries, medical conditions, or spinal
problems should consult a doctor before beginning yoga.
Those with medical conditions should find a yoga teacher
who is familiar with their type of problem and who is willing
to give them individual attention. Pregnant women can
benefit from yoga, but should always be guided by an experienced
teacher. Certain yoga positions should not be
performed with a fever, or during menstruation.
Beginners should exercise care and concentration
when performing yoga postures, and not try to stretch
too much too quickly, as injury could result. Some advanced
yoga postures, like the headstand and full lotus
position, can be difficult and require strength, flexibility,
and gradual preparation, so beginners should get the help
of a teacher before attempting them.
Yoga is not a competitive sport; it does not matter
how a person does in comparison with others, but how
aware and disciplined one becomes with one’s own body
and limitations. Proper form and alignment should always
be maintained during a stretch or posture, and the
stretch or posture should be stopped when there is pain,
dizziness, or fatigue. The mental component of yoga is
just as important as the physical postures. Concentration
and awareness of breath should not be neglected. Yoga
should be done with an open, gentle, and non-critical
mind; when one stretches into a yoga position, it can be
thought of as accepting and working on one’s limits. Impatience,
self-criticism, and comparing oneself to others
will not help in this process of self-knowledge. While
performing the yoga of breathing (pranayama) and meditation
(dyana), it is best to have an experienced teacher,
as these powerful techniques can cause dizziness and
discomfort when done improperly.
Side effects
Some people have reported injuries by performing
yoga postures without proper form or concentration, or
by attempting difficult positions without working up to
them gradually or having appropriate supervision. Beginners
sometimes report muscle soreness and fatigue
after performing yoga, but these side effects diminish
with practice.
Research & general acceptance
Although yoga originated in a culture very different
from modern America, it has been accepted and its practice
has spread relatively quickly. Many yogis are
amazed at how rapidly yoga’s popularity has spread in
America, considering the legend that it was passed down
secretly by handfuls of followers for many centuries.
There can still be found some resistance to yoga, for
active and busy Americans sometimes find it hard to believe
that an exercise program that requires them to slow
down, concentrate, and breathe deeply can be more effective
than lifting weights or running. However, ongoing
research in top medical schools is showing yoga’s effectiveness
for overall health and for specific problems,
making it an increasingly acceptable health practice.
