Although personal choreography may make some sex workouts more intense, despite what might feel like a sweaty, heart-thumping time, on average, heart rates at the peak of sexual intensity don’t go as high as some people might assume.

Q. I know that regular exercise is good for you, but does the vigorous nature of sex make it harder on the heart?
A. The classic tale of a guy having a heart attack during sex is a pretty rare event. A 2010 study in the Lancet reported that only 2.2% of heart attacks happen during sex. Still, sexual exercise is physical activity and, at times, can feel quite intense. This has led several researchers to study the heart-rate and blood pressure response to sexual activity.
Although personal choreography may make some sex workouts more intense, despite what might feel like a sweaty, heart-thumping time, on average, heart rates at the peak of sexual intensity don’t go as high as some people might assume. A 1976 study in the American Heart Journal rigged 10 healthy men (from 24 to 40 years old) to heart-rate monitors and automatic blood pressure cuffs. The men were told to wear the devices during five occasions when they had sex in the privacy of their homes with their wives. The average maximal heart rate reached was 114 to 117, depending upon whether the man was on top or not. Heart rates fell quickly back to resting rates within two minutes after the man reached an orgasm. (Interestingly, being on top or on bottom elicited similar heart rates.) For younger people, this works out to be an average of 60 to 65% of maximum heart rate, which is considered a moderate, not intense level—about the intensity of a brisk walk.
