Here is a another excerpt from 77 Surprising Benefits of Yoga by Meredith Walker.
Disease Prevention
Doctors and nurses love yoga because studies indicate that it can help prevent the following diseases:
58. Heart disease. Yoga reduces stress, lowers blood pressure, keeps off weight, and improves cardiovascular health, all of which lead to reducing your risk of heart disease.
59. Osteoporosis. It is well documented that weight-bearing exercise strengthens bones and helps prevent osteoporosis. Additionally, yoga’s ability to lower levels of cortisol may help keep calcium in the bones.
60. Alzheimer’s. A new study indicates that yoga can help elevate brain gamma-aminobutyric (GABA) levels. Low GABA levels are associated with the onset of Alzheimer’s. Meditation like that practiced in yoga has also been shown to slow the progression of Alzheimer’s.
61. Type II diabetes. In addition to the glucose reducing capabilities of yoga, it is also an excellent source of physical exercise and stress reduction that, along with the potential for yoga to encourage insulin production in the pancreas, can serve as an excellent preventative for type II diabetes.
Symptom Reduction or Alleviation
Medical professionals have learned that the following diseases or disorders can all be helped by maintaining a yoga practice.
62. Carpal tunnel syndrome. Individuals with carpal tunnel syndrome who practiced yoga showed greater improvement than those who wore a splint or received no treatment at all. Researchers saw improved grip strength and reduction of pain in the study participants.
63. Asthma. There is some evidence to show that reducing symptoms of asthma and even reduction in asthma medication are the result of regular yoga.
64. Arthritis. The slow, deliberate movement of yoga poses coupled with the gentle pressure exerted on the joints provides an excellent exercise to relieve arthritis symptoms. Also, the stress relief associated with yoga loosens muscles that tighten joints.
65. Multiple sclerosis. According to this article, “yoga is now recognized as an excellent means of MS management.” Additionally, National Center for Complementary and Alternative Medicine is funding a clinical trial of yoga for treating multiple sclerosis.
66. Cancer. Those fighting or recovering from cancer frequently take advantage of the benefits that yoga provides. Cancer patients who practice yoga gain strength, raise red blood cells, experience less nausea during chemotherapy, and have a better overall well-being.
67. Muscular dystrophy. Using yoga in the early stages of muscular dystrophy can help return some physical functions. The practice of Pranayam yoga helped one teen regain many of his abilities lost to muscular dystrophy.
68. Migraines. Regular yoga practice has been shown to reduce the number of migraines in chronic migraine sufferers.
69. Scoliosis. Yoga can straighten the curvature of the spine associated with scoliosis.
70. Chronic bronchitis. Exercise that does not elevate respiration, yet increase oxygen levels in the body is ideal for treating chronic bronchitis. Luckily, yoga can do this, as well as aerate the lungs and provide energy.
71. Epilepsy. Focusing on stress reduction, breathing, and restoring overall balance in the body are the focus of how yoga can help prevent epileptic seizures.
72. Sciatica. The intense pain associated with sciatica can be alleviated with specific yoga poses.
73. Obsessive Compulsive Disorder. Studies of people with OCD have shown that practicing yoga has lead to a reduction in symptoms–resulting in less medication or medication no longer needed.
74. Constipation. Due to the practice of yoga and overall better posture, the digestive and elimination systems work more efficiently. If the practitioner also has a healthy diet, any constipation will be eliminated through yoga.
75. Allergies. Using a neti pot to clear the sinuses is an ancient form of yoga to help reduce or eliminate allergy symptoms. Certain types of breathing can also help clear the nasal passages.
76. Menopause. Yoga practice can help control some of the side effects of menopause.
77. Back pain. Yoga reduces spinal compression and helps overall body alignment to reduce back pain.”
