Good for a Woman’s Heart

May Cure Your Headache
Say goodbye to the old standby “Not tonight, Dear. I have a headache.” It turns out sex can help with pain, and that includes some kinds of headaches, such as migraines. Not feeling frisky? Try: “Not tonight, Honey. I have a highly contagious stomach bug.” Works every time.

Sharpens Your Mind
Sex has been linked to the making of new brain cells, and that’s a good thing. People over 50 who had more sex were better able to recall numbers and do basic math, and the difference was pretty big. It seemed to help men more than women, but both did better than those who had less sex.

Makes You Happy
You don’t have to overdo it -- once a week is plenty. More than that, and the effect fades. But scientists only studied couples in committed relationships, so if you’re trying to meet your quota by picking up strangers at your local bar, all bets are off.

Helps You Sleep
Orgasm triggers a surge of endorphins and oxytocin in both men and women, and that dulls pain and relaxes you. Both of those can help you sleep more easily, though according to scientists -- and many women -- the effect is more pronounced in men.

You Could Make a Baby
If you’re trying to have a baby, the more sex you have, the more likely you are to hit the right time of the month. But more sex may also prime women for pregnancy and improve sperm quality in men, which can speed things along.

Helps Your Future Self
People who have more sex may have better quality of life -- and not just now, but in the future, too. If you have an active sex life in middle age, you’re more likely to keep it up as you get older, which is linked to better health and happiness.
