Answer:
D. endorphins
Explanation:
Endorphins, also called happiness hormones, are chemicals produced by the body itself structurally very similar to opioids (opium, morphine, heroin) but without their negative effects. It is estimated that there are about 20 different types of endorphins distributed throughout the body, some of them are located in the pituitary gland and are responsible for making communication between neurons possible. These natural chemicals produce strong analgesia, stimulate the pleasure centers of the brain creating satisfactory situations that contribute to eliminate discomfort and reduce painful sensations. When we feel pain, the endorphins act as endogenous analgesics, inhibiting the transmission of pain to the brain.
There are numerous formulas to put into action the production of endorphins, without using medications and thus be able to fully enjoy each day, such as the exercise of physical exercises. Keep in mind that our body releases small doses of endorphins that in turn, in a short time, are eliminated by enzymes, also made by our body. This is because if the endorphins circulated freely through our body, we would not feel the pain and this is the only way to realize that there is a physical problem, nor could we value happiness when we achieve it. While it is not possible or convenient to eliminate these enzymes, there are different ways to make the production of this hormone constant. The method is simple, we must strengthen the situations that are pleasing to us thus increasing our mood and as a consequence the production of this hormone will be stimulated. One of the first steps is to enjoy the little things that happen to us daily.
