Answer: Endorphins

Explanation:

Endorphins are chemicals produced naturally by the nervous system to cope with pain or stress. They are often called "feel-good" chemicals because they can act as a pain reliever and happiness booster.

Endorphins are primarily made in the hypothalamus and pituitary glands, though they may come from other parts of the body as well. The well-known "runner's high" that is felt after lengthy, vigorous exercise is due to an increase in endorphin levels.
