Staying active is essential for long-term wellness, but scientists now say one form of physical activity may offer surprising heart-health benefits: sex. A new analysis suggests that men who maintain a regular sexual routine may significantly reduce their risk of heart disease as they age.

Researchers from Qingdao University in China reviewed data from multiple U.S. studies involving more than 17,000 adults. Their findings, published in Scientific Reports, show a clear trend—men who had sex less than 12 times per year faced a higher risk of heart disease and early mortality. In contrast, men who engaged in sexual activity roughly 100 times per year—about twice a week—had much lower cardiovascular risks. Even moderate activity, around once a week, was associated with measurable benefits.

Experts say the explanation is simple. Sexual activity increases heart rate, improves circulation, and reduces stress, all of which play key roles in cardiovascular health. Dr. Alexis Missick of UK Meds noted that sex supports both emotional well-being and physical fitness, calling it “literally good for your heart.”

However, researchers also cautioned that balance matters. Extremely high frequency—more than once daily—may reduce some of the health advantages, echoing the well-known principle that excessive physical exertion can outweigh benefits.

The study’s authors stress that sexual activity can serve as a helpful indicator of overall health. Men experiencing very low or unusually high frequency may want to discuss their situation with a medical professional.

As with most wellness habits, the message is clear: moderation supports a healthier heart.
