Sexual intercourse is not only a pleasant and exciting activity, but it also provides several health benefits. In women, sex triggers the production of oxytocin, which in turn causes feelings of affection and nurturing instinct. In men, on the other hand, sex increases the testosterone levels, strengthening muscles and bones and promoting the transport of a hormone called DHEA, which plays an important part in the immune system.
In addition, sex promotes cardiovascular health, as shown in a study by Queens University. They have found that men who had sex three or more times a week had two times less chance of heart attack or stroke.
Physiological benefits of sex
Sex can help with different types of pain. It is a known fact that sexual intercourse helps against menstrual cramps because the orgasm causes the uterine muscles to contract and use up extra prostaglandines, hormones responsible for menstrual cramps.
Sex also helps against headache, because it stimulates the production of endorphins, which act as mild, natural morphine.
Sexual activity can also be used to lose weight and to keep in good shape. During sex, some muscles are built and strengthened, and the blood flow through the entire body is increased, providing more oxygen to the muscles.
In addition, it is estimated that 30 minutes of sex burns 150 calories, which, of course, promotes weight loss.
People suffering from flu or a common cold could benefit greatly from sex. This is because during sex the body releases antibodies that search and destroy the viruses. Not only that, sex can reduce fever also, by causing intensive sweating, which cools the body down and reduces the temperature.
Finally, sex promotes good skin. During sexual intercourse the body releases hormones that clear the skin from the inside, making it smooth and naturally glowing.
Benefits of sex for the brain and mental state
It has been proven many times that sex is a great way to reduce stress and anxiety. This is due to the endorphins that are released during intercourse. After sex, a person feels relaxed, and those who have sex on a regular basis are generally less stressed and anxious.
Men falling asleep immediately after having sex is not a stereotype, but it is a natural reaction to endorphin release that gives complete body relaxation. This happens to women too, although many of them would never admit it. In fact, some scientists claim that sex can be used as an all-natural remedy against insomnia, with no side effects.
Finally, sex improves mental function and brain power. This is a result of increased blood flow that occurs during and immediately after sex. More blood means more oxygen to the brain, and thus the improved brain function.
