The adrenaline is often called "pain hormones." Whenever we get angry or are intimidated, adrenaline is released. There is also a hormone called melatonin, which is released before bedtime and at night, so that people can sleep better. Researchers believe that if a person deliberately to increase the "happy hormone" and discharge "pain hormones" from the body, that person will become happier. The secretion of adrenaline is often associated with stress, for example, caused by anger when arguing with family members.
