The science-backed reason to get frisky tonight.

Have you heard? Sex isn’t all fun and games; science says there are plenty of incredible health benefits from getting frisky, too. Everything from your mood to your waistline can get a boost from your bedroom activity. And thanks to new research, the good news doesn’t stop there. Having sex at least once a week can also help you live longer, scientists say.

In the study, researchers at the University of California in San Francisco tracked the sexual lives of 129 mothers in relationships for one week. The participants provided a daily report of their overall relationship satisfaction, as well as instances of conflict, support, and intimacy with their partners.

When the researchers compared the women’s reports to their blood samples, they found a fascinating pattern. Mothers who had sexy time with their partners at least once during that week had significantly longer telomeres — or the part of a cell responsible for aging — than those who did not.

What do telomeres have to do with a longer life?

Over time, the telomeres found in your cells break down as a result of aging, poor diet, and high alcohol use, the researchers said. But these results show that regular sex can repair and lengthen them, keeping your cells healthy and young.

Such a small study warrants further research, of course. And there are plenty of other science-backed ways to extend your life — so don’t feel pressured to get frisky.

But considering what happens to your body when you stop having sexy time, this research might be on to something. Plus, previous studies have also suggested that couples should have sex at least once a week to reap the most rewards. Translation: It can’t hurt to fool around with your partner tonight.
