Answer:
the hormones produce a happy feeling.
Explanation:
The hormone the testosterone and endorphins are hormones that are produced by the endocrine system as a result of exercise and intense physical activities. These hormones are known as the happy hormones. They have the same effect as morphine would do on the body - they diminish the effect of pain and stress. The hormones do so by counteracting the effect of the stress hormone, cortsoids, that are produced in stressful situations. These hormones wear down the person emotionally and the person will be stressed. A person who exercises produces a happy feeling and healthy emotions. In addition, the hormone provides overall feelings of well-being and contribute to the manufacture of the T-lymphocytes thereby strengthening the immune system.
