Exercise triggers the release of several chemicals in the body, including hormones. Many of these chemicals are released during cardiorespiratory exercises, such as walking, running, or cycling. Exercise releases a variety of chemicals in the body, including epinephrine (adrenaline), which raises cardiac output. Other chemicals, such as norepinephrine, constrict blood vessels in the non-exercise areas of the body.

Researchers have hypothesized that aerobic exercise releases chemicals in the brain that lower levels of stress hormones. Additionally, aerobic exercise releases endorphins, which are the body’s natural mood elevators. Endorphins are responsible for the runner’s high and other euphoric effects associated with exercise. These chemicals also help us cope with stress. Exercise also boosts our self-esteem, which is another benefit of physical activity.

Endorphins are a hormone released in the brain during physical activity. Exercise enhances mood by producing dopamine, which improves feelings of pleasure and happiness. Studies have also shown that exercise reduces levels of cortisol and adrenaline, two important stress hormones. However, exercise is not to be overdone, as the body needs time to heal. Exercise should be a part of a balanced diet and lifestyle.
