Yoga has been shown to directly impact happiness in several ways: 1) Practicing yoga lowers levels of depression and anxiety even after a single session by improving mood and changing brain chemistry. 2) Regular yoga practice creates long-term changes in the body and mind, leaving people feeling happier and healthier as they become less tired and prone to negative emotions. 3) When the body and mind are healthy from yoga, people are better able to deal with situations in a calm and patient manner.
