Regular exercise is a wonderful approach to relieving stress. When we exercise we burn off excess adrenaline that often triggers anxiety.
Exercise also stimulates production of endorphins.
Our own endorphins are considered to be 200 times more potent than morphine. Regular exercise helps a person to regain their sense of control. Emotional well being is often reported as a by-product from folks who exercise regularly. Increased self-esteem and a sense of success often accompany consistent physical activity, which then extends to other areas of life. So during the day, try to take deep breaths and follow your breath.
