1. Sex relieves headaches One of the health benefits of sex is its pain-relieving effect. The hormone oxytocin is released in our body every time we have sex. Due to this secretion, endorphins are released, which are called “hormones of happiness”. Higher levels of endorphins are associated with experiencing positive emotions, but also with reducing the sensation of pain. During sexual arousal, the levels of oxytocin in the body increase, but they are also the reason for obtaining an orgasm. Studies show that increasing oxytocin levels can relieve headaches, cramps, and body aches. 2. Reduces stress and improves sleep People who have regular sex feel calmer, happier and cope better with stress than those who have an irregular sex life, a new study shows. After having an orgasm, we feel a strong wave of calmness, release from tension and relaxation, which is why men usually fall asleep after sex. Many with a regular sex life report that they sleep much better at night and feel much more energetic and fresh the next day. And improving sleep also contributes to effective coping with stress and tension. NEWS_MORE_BOX 3. Boosts Immunity The frequency of having sex is related to the function of the immune system.
