Exercise is an important means to improve health and prolong life. However, the more exercise, the better. Excessive exercise damages the immune function of the body and affects health.
This is because people will produce more hormones such as adrenaline and cortisol during strenuous exercise. When these hormones are increased to a certain amount, the ability of immune organ spleen to produce white blood cells will be greatly reduced, and the activities of A cells, B cells and natural killer cells (NK cells) in lymphocytes will be greatly reduced, among which natural killer cells can be reduced by 35%.
