How does exercise help to reduce stress

Exercise stimulates the production of neurohormones, such as norepinephrine, which have been linked to improvements in cognitive function, mood, and learning.

Explanation:

Exercise also encourages the development of a physiological body system; precisely, this system is responsible for the proper coping of the body and mind with stress. The cardiovascular system begins to accelerate during exercise, sends signals to the nerves and muscles, and in return, the body copes with anxiety every time. Sitting and no activity does not create coordination between organs, which also affects the psychophysical health of humans. Many studies have shown that constant exercise raises the level of energy in a person, which results in elevating mood in a person and thus reducing stress.
