Endorphin, also known as endorphin or endorphin, is an endogenous (pituitary gland secreted) morphine-like biochemical synthetic hormone.

It is an amino compound (peptide) secreted by the pituitary gland and the hypothalamus of vertebrates.

Endorphins are usually secreted in the following ways: 1. A person’s sense of accomplishment can stimulate the secretion of endorphins. 2. When people's body and mind are in a relaxed and happy state, it can promote brain secretion. 3. Exercise for more than 30 minutes can also stimulate the secretion of endorphins. Running, Tai Chi and other exercises can increase the secretion of endorphins. 4. Deep breathing is also a condition for producing endorphins. When we are nervous, taking a deep breath can relieve our tension and increase the secretion of endorphins.

Endorphins are a type of endogenous peptide substance produced by the body itself and have morphine-like effects. In addition to their analgesic function, these peptides also have many other physiological functions, such as regulating body temperature, cardiovascular, and respiratory functions. Endorphins are a general term for neuropeptides with morphine-like activity.
