Yoga

 

Definition

The term "yoga" comes from a Sanskrit word meaning "union." Yoga combines physical exercises, mental meditation, and breathing techniques to strengthen the muscles and relieve stress.

Purpose

Yoga has been practiced for thousands of years as a life philosophy to join the individual self with what practitioners call the Divine, Universal Spirit, or Cosmic Consciousness. However, very few individuals in the United States as of 2004 practiced yoga in this way; rather, yoga is performed as part of an exercise program to increase general health, reduce stress, improve flexibility and muscle strength, and alleviate certain physical symptoms, such as chronic pain. Because yoga is a low-impact activity and can include gentle movements, it is commonly used as part of physical therapy and rehabilitation of injuries.
Clinical and psychological studies have demonstrated that performing yoga has the following benefits:
  • Physical postures strengthen and tone muscles, and when performed in rapid succession, can provide cardiovascular conditioning.
  • Meditation and deep breathing can reduce stress, thereby lowering blood pressure and inducing relaxation.
  • Mind/body awareness can influence mood and self-esteem to improve quality of life.
In addition to exercise and stress reduction, yoga is also used therapeutically to help children and adolescents with medical conditions. Yoga instructors experienced in adapting yoga postures for individuals with special needs teach yoga to children and adolescents with Down syndrome, cerebral palsy, seizure disorders, spinal cord injury, multiple sclerosis, cancer,
autism, Asperger's syndrome, attention deficit hyperactivity disorder (ADHD), psychiatric disorders, learning disabilities, and other disabilities to help improve physical and mental functioning. Many physicians may recommend yoga for patients with hypertension, asthma, stress-related disorders, and depression. Growing interest in alternative and complementary medicine has increased the popularity of yoga in the United States and spurred research into its medical benefits. Many hospitals offer alternative or integrative medicine centers that include yoga classes.
Some yoga instructors have even pioneered yoga for infants and toddlers, practiced with one or both parents. Yoga for infants and toddlers can improve sleep, ease digestive problems, facilitate neuromuscular development, strengthen the immune system, deepen parent-child bonds, serve as an outlet for creative play and self-expression, and reduce stress and anxiety for both parents and children.

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 well-designed 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.

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.

Training & certification

Many different schools of yoga have developed in America, and beginners should experiment with them to find the best-suited routine. Hatha yoga schools emphasize classical yoga postures, and raja yoga schools concentrate on mental discipline and meditation techniques. In America, there are no generally accepted standards for the certification of yoga teachers. Some schools certify teachers in a few intensive days and some require years of study before certifying teachers. Beginners should search for teachers who show respect and are careful in their teaching, and should beware of instructors who push them into poses before they are ready.
