Yoga improves breathing. The basis of yogic breathing practices lie in pranayama, or yogic breathing techniques. These techniques, which are integrated into the vast majority of yoga classes, can be amazing for restoring balance and vitality to the body and mind. Controlled breathing can increase energy levels and relax the muscles, while reducing stress, anxiety and depression. On a physiological level, regular yoga practice has been found to improve lung capacity and breathing both in healthy adults and those who suffer from asthma.
