“Multiple studies point to the positive effects of yoga on mental and physical health, as well as on personal development. Yoga alleviates chronic pain. It helps manage coronary artery disease, asthma, diabetes, lymphoma, and breast cancer. Yoga helps individuals suffering from mental health problems, such as depression, anxiety, obsessive-compulsive disorder, post traumatic stress disorder, and schizophrenia.
Regular yoga practice also benefits healthy individuals, improving psychological well-being, satisfaction with life, and self-esteem, and reducing stress and performance anxiety. Studies have also found that yoga reduces fatigue and negative affect, while increasing positive affect and giving a feeling of being energised.”
