It is generally believed that human beings have sex either for pleasure or reproduction. However, the number of people driven with these motivations has been reducing steadily during the recent years. The majority of humans use sex as the most pleasant and available remedy for a whole bouquet of problems.

It is an open secret that a person gets into a cheerful mood during an act of love. In addition to purely psychological satisfaction, the human body produces endorphin - the hormone in charge of elevated spirits and positive perception of the environment. Researchers say that such inspiration comes from the activity of certain brain centers, which change the hormonal status of the body. Good quality sex produces a spiritually elevating effect on the chemical level, which does not require any additional efforts.

Prior to the culminating moment of an act of love, orgasm, the brain emits a dose of oxytocin - the hormone of the posterior lobe of pituitary. Oxytocin results in the production of sedative endorphins - natural analogues of morphine. Sex spurs the production of estrogen with women - the substance, which eases premenstrual pains. Therefore, sex is the best painkiller.
