The health benefits of sex

Insomnia: sex reduces tension thanks to the release of endorphins, which helps you sleep more deeply and restfully.
Anxiety and low mood: sex calms anxiety and eases frustration, and orgasm helps against depression, because of its effect on dopamine and serotonin in the brain. A balance between these two neurotransmitters is essential for mental health.
Period problems: regular sex helps regulate oestrogen and progesterone, and so the menstrual cycle, and reduces period pain.
Skin: sex gives the skin a glow and reduces skin inflammation and freckles, for two reasons. Oestrogen, sometimes called the beauty hormone, is better regulated, which also improves the shape of the breasts and greatly reduces excess hair. And sweating during sex (especially when the woman is not dehydrated) helps the body get rid of accumulated toxins.
Hair: regular sex improves oestrogen release and so helps prevent hair loss caused by low oestrogen; hair loss caused by poor nutrition, however, cannot be treated with sex.
Fertility: regular intercourse raises progesterone and increases fertility in women, so it helps women with weak ovaries or long cycles (more than a month).
Muscle pain: especially back pain, which is often psychological in origin, is eased by the better mood that comes with sex, as are migraines and headaches, thanks to the endorphins the body releases. Regular sex also helps with some stress-related conditions such as ulcers and indigestion.
Circulation and muscles: sex is a form of exercise, especially for men, and it needs fitness from both partners, so a sex life is also a motive to exercise, which in turn improves your sex life.
Immunity: sex may help protect against colds and flu, because it stimulates immune cells, especially T cells, which protect the body from disease.
Bones and ageing: oestrogen helps prevent osteoporosis and gives skin and hair a healthy look, delaying the signs of ageing.
Creativity: sex clears the mind and helps you relax and work well, while a lack of sex increases aggression and tension, which reduces creativity.
Teeth: sex before bed increases saliva, which makes the mouth a poor place for bacteria to grow, and having a partner is an incentive to look after your mouth and teeth.
