The effects exercise can have on your weight, body composition, and sense of confidence might have a lot to do with it, too. Dr Justin Lehmiller, director of the social psychology program at Ball State University and author of the blog Sex and Psychology, cites one study out of Duke University linking obesity with sexual difficulties and a lowered sex drive.
And even if you don't take antidepressants or struggle with your weight, exercise could still boost your sex drive. A 2010 study out of the University of Texas measured women’s physical reactions to erotic films following a run on a treadmill. Women who hit the treadmill showed a greater genital response than a control group that didn’t run. “Findings like this suggest that exercise has a direct impact on how aroused women become in response to sexual stimuli,” adds Lemiller.
The effects of that "runner's high" so many exercisers rave about might yield bedroom benefits, too, adds Dr Jennifer R. Berman, a practicing urologist and women’s sexual health expert.
“[Exercise] can be responsible blood flow increases to your brain and your genital area," she says. The increase of endorphins from your workout helps create a sense of euphoria for the entire body, she adds. "Anything that improves health in any way has antioxidant and anti-inflammatory elements, and it’s working all over."
