Regular ejaculation appears to be linked with better heart health and longer life, though the relationship is more nuanced than a simple cause-and-effect. A 10-year study of 918 men in South Wales found that men who ejaculated twice or more per week had a 50% lower risk of death compared to men who ejaculated less than once a month. Larger studies have found similar patterns, with sexually active adults showing lower rates of heart disease mortality and death from all causes.
What the Research Shows
The most compelling data comes from a 2020 analysis of over 15,600 U.S. adults. People who had sex more than 52 times per year (roughly once a week) had 49% lower overall mortality compared to those who had sex zero to one times per year. Heart disease mortality specifically was 21% lower in the more sexually active group, though that particular number wasn’t statistically strong enough to rule out chance. The drop in cancer mortality (69% lower) and death from other causes was more robust.
A separate study of 495 heart attack survivors found that weekly sexual activity was associated with a 10% reduction in heart disease mortality and a striking 44% drop in non-heart-disease mortality. Taken together, these studies consistently point in the same direction: people who ejaculate regularly tend to live longer and have fewer cardiovascular events.
There’s an important caveat. These are observational studies, meaning they can’t prove ejaculation itself is the reason for better outcomes. People who are sexually active more often also tend to be healthier overall, more physically fit, less stressed, and in stable relationships. All of those factors independently protect the heart. The benefit is real in the data, but untangling how much comes from ejaculation itself versus the lifestyle that surrounds it is difficult.
How Ejaculation Affects Your Heart in the Moment
During orgasm, your heart rate climbs to an average peak of about 114 to 117 beats per minute, and blood pressure rises to roughly 163/81. That’s comparable to climbing two or three flights of stairs briskly. The American Heart Association classifies sexual activity at about 3 to 5 METs of exertion (a MET is a unit measuring energy expenditure), putting it on par with a moderate walk or light cycling.
This brief cardiovascular spike is actually part of why sex may benefit the heart. Like any moderate physical activity, it temporarily raises your heart rate, increases blood flow, and gives your cardiovascular system a mild workout. The body also releases a cascade of hormones during orgasm, including ones that reduce stress, lower the stress hormone cortisol, and promote relaxation afterward. Chronic stress is a well-established risk factor for heart disease, so anything that reliably counters it has potential protective value.
Ejaculation Without a Partner
Most of the large studies measure sexual frequency with a partner rather than masturbation specifically. The South Wales study did track ejaculation frequency directly, regardless of how it happened, and still found the protective association. The physiological response during orgasm is similar whether it occurs during partnered sex or solo: heart rate rises, blood pressure spikes briefly, and the same hormonal release follows. However, partnered sex involves more overall physical exertion and may carry additional psychological benefits like bonding and emotional connection, which also support cardiovascular health.
When Ejaculation Could Be Risky
For the vast majority of people, the physical demands of sexual activity and orgasm are modest and safe. But for people with existing heart conditions, there are specific situations where the exertion matters. The American Heart Association considers sexual activity reasonable for cardiac patients at low risk of complications, specifically those who can handle moderate exercise (the equivalent of a brisk walk) without chest pain, shortness of breath, or abnormal heart rhythms.
The risk goes up in certain categories. People with Class III or IV heart failure, meaning symptoms appear even with mild physical activity, face a higher chance of complications during sex. Anyone who has had heart surgery within the past one to two weeks should also wait. And if sexual activity itself triggers cardiovascular symptoms like chest pain, dizziness, or severe breathlessness, that’s a signal to hold off until the underlying condition is better controlled.
For people recovering from a heart event, cardiac rehabilitation and regular exercise can lower the risk that sexual activity poses. Building back general fitness makes the heart more resilient to the brief spike in demand that orgasm creates.
The Bigger Picture
Ejaculating regularly is associated with meaningful reductions in mortality, and the physical and hormonal effects of orgasm offer plausible reasons why. But it works best understood as one piece of a larger cardiovascular puzzle. The people in these studies who had sex frequently were also more likely to exercise, maintain healthy weight, and manage stress effectively. Ejaculation alone isn’t a substitute for those habits, but the evidence strongly suggests it’s a healthy addition to them. A consistent frequency of once or twice a week is the threshold where benefits tend to appear in the research.
