It has been shown to enhance social well being through a sense of belonging to others, and improve the symptoms of depression, attention deficit and hyperactivity, and sleep disorders. Also, yoga can improve symptoms of schizophrenia when it is done alongside drug therapy (Yoga and Mental Health, Huffington Post 2013).
Also, yoga has been shown to increase the level of gamma-aminobutyric acid, or GABA, a chemical in the brain that helps to regulate nerve activity. This is especially relevant to people who have anxiety disorders in which GABA activity is low (Yoga and Your Mood, the Ultimate Yogi).
Yoga also improves the mood, behavior, and mindfulness of high school students taking yoga classes in addition to PE than students taking PE alone (yoga classes helps highschool students). It has been shown to improve workplace well being and resilience (The Effectiveness of Yoga for Well Being in the Workplace).
But, let’s not stop here. Yoga’s benefits extend to adult caregivers who experience lower life satisfaction, depression, and stress and high levels of biological markers for inflammation. One study found that practicing a 12-minute daily eight week program of yoga exercise resulted in reducing markers of inflammation in adults taking care of loved ones stricken with Alzheimer’s and other forms of dementia (UCLA’s Late-Life Depress, Stress and Wellness Research Program).
Clearly, mind and body practices, like yoga, meditation, deep breathing and prayer help to reduce stress and improves stress-related nervous system imbalances (Psychological Benefits of Yoga). But, how do they do this? Is there one main mechanism at play here?
Researchers say it is the relaxation response that accompanies these mind and body practices that lead to the many improvements to physical and mental health. A new study from investigators at the Benson-Henry Institute for Mind/Body Medicine at Massachusetts General Hospital (MGH) and Beth Israel Deaconess Medical Center (BIDMC) finds that the deep, physiological state of restinduced by such practices produces immediate positive change in the expression of genes involved in immune function, energy metabolism and insulin secretion (Genes and Physiological Pathways Altered in the Relaxation Response, Science Daily, May 2013).
What is a deep state of physiological relaxation? It is a change in calm and relaxation that takes place on a neurobiological level. Even having a good time out with friends or family is not enough to relax your biology on a cellular level. It takes a certain amount of brain and body stimulation to laugh, animatedly move our faces and bodies, and to listen and respond effectively to social cues. We need enough adrenaline pumping to our brain, heart and muscles to do this. So, you see, even socializing, playing an enjoyable game of tennis or golf, or shopping with a friend is actually a state of biochemical tension. For the body to relax at the nerve and cellular level, we need to alter body processes that shift us biochemically from a state of excitement and tension to a state of calm, deep rest and relaxation. Only deep breathing that accompanies mind-body practices like yoga can do this.
