American physiologists have done a lot of surveys and found that imperfect sex life is an important reason for some people's insomnia. When a person is in a period of strong sexual desire and cannot get physiological outlet for a long time, the nervous system will be in a highly excited state, anxious and irritable, and insomnia will follow one after another.

This is more prominent in women. This is because there is a big gap in the moment between men and women's sexual desire, orgasm and sexual desire subsidence. Men's sexual desire can be stimulated quickly, and they can reach orgasm quickly during the entire sexual intercourse. After orgasm, sexual desire can quickly subside. Therefore, men can fall asleep quickly as soon as they reach orgasm (even after masturbating).

But women are different. Women’s sexual desire has a longer activation process, and the “platform” period is also longer. Even after reaching orgasm, the sexual desire subsides slowly, so during sexual intercourse, women It is more difficult for women to achieve perfect harmony than for men, so women are more likely to suffer from insomnia. Therefore, American psychologists have proposed that the lack of normal sex life or the disharmony and imperfection of sex life are important reasons for women's insomnia.

Therefore, a perfect and harmonious sex life can promote sleep. Because after passionate sexual intercourse, the nervous and excited body can relax, the muscles can stretch out from the tiredness after satisfaction, and the mind can relax after the joyful drifting. Therefore, the couple needs to enjoy the wonderful experience of sexual life together, and then sleep together in the quilt and fall asleep together.

For women, breasts are not only lactation organs, but also sexual organs. During sexual life, the breasts will undergo cyclic changes: during the sexual excitement period, the breast veins are congested, and the breasts become enlarged and plump; during the sexual duration period, the areolas are congested and the nipples are erect; during orgasm, these changes also reach their peak; orgasm Afterwards, the areolar congestion subsided quickly, and the enlarged breasts gradually returned to their original shape after a quarter of an hour.

These reactions of the breasts regulate breast function. If there is a long-term lack of sexual activity, this physiological regulation will be lacking, which will easily induce breast lobule hyperplasia and breast cancer. Therefore, couples should have regular sex life.
