11 Things That Happen To You When You Stop Having Sex

5. You May Have Trouble Sleeping

Laura Berman, the director of the Berman Center for Women’s Sexual Health, says the power of sex can actually cure insomnia. Sex releases feel-good endorphins as well as boosting a woman’s estrogen levels, which can “enhance a woman’s REM cycle for a deeper sleep” all while inhibiting the release of stress-inducing hormone cortisol.

Men have their own sleepy anatomical responses after orgasm. Their bodies release a biochemical called prolactin, which is directly responsible for feelings of fatigue. Sex, it seems, has an overall tiring effect on the human body.

Furthermore, the inverse seems to be true as well! Those of us who get more sleep also have the highest level of sexual desire. You’re either in a good loop or a bad one.
