When we think about the pillars of longevity, we usually focus on exercise, nutrition, sleep, stress management, and metabolic health. These are unquestionably important, but there is another aspect of human health that is often overlooked: sexual wellness.
Many people think of sex as simply a quality-of-life issue. However, emerging research suggests it may also reflect overall health and longevity. A recent study involving more than 17,000 American adults followed for nearly nine years found that sexual frequency was associated with both cardiovascular health and all-cause mortality. While the study does not prove that sex itself extends life, it reinforces something I have believed throughout my career: our intimate relationships and sexual health are powerful indicators of our overall well-being.
A Landmark Study
Researchers analyzed data from 17,243 adults participating in the National Health and Nutrition Examination Survey (NHANES). Participants were followed for a median of 106 months, or approximately 8.8 years, while researchers tracked cardiovascular disease and all-cause mortality.
After adjusting for age, smoking, obesity, diabetes, hypertension, and numerous other health factors, individuals reporting regular sexual activity experienced lower rates of cardiovascular disease and lower overall mortality than those reporting very infrequent sexual activity.
Perhaps the most interesting finding was that the relationship followed a U-shaped curve, meaning more was not necessarily better.
The Sweet Spot
The study found that individuals reporting approximately 52 to 103 sexual encounters per year experienced the lowest mortality risk. This translates to roughly one to two sexual encounters per week.
Those reporting sexual activity less than once per month had the highest rates of cardiovascular disease and all-cause mortality, while increasing frequency beyond about two times per week did not appear to provide additional measurable benefit.
For many couples, this is encouraging. It suggests that maintaining a consistent, satisfying intimate relationship may be one characteristic of healthy aging rather than striving for unrealistic expectations.
Why Might This Matter?
Sexual activity is one of the most integrated expressions of human physiology. It depends on healthy blood vessels, balanced hormones, cardiovascular fitness, nervous system function, restorative sleep, emotional well-being, and meaningful interpersonal connection.
When these systems function well together, sexual health often follows naturally. Conversely, declining sexual function is frequently one of the earliest signs that something else is beginning to change.
For men, erectile dysfunction often precedes cardiovascular disease because the small penile arteries become diseased before the larger coronary arteries. Women experiencing declining libido, vaginal discomfort, or reduced sexual satisfaction may be demonstrating early signs of hormonal changes, endothelial dysfunction, chronic inflammation, or metabolic disease.
Rather than viewing these symptoms in isolation, I believe they should prompt us to ask a much bigger question:
What is the body trying to tell us?
Sexual Health Is a Biomarker
One reason I find this study so compelling is that it reinforces a philosophy I have incorporated into my practice for years.
I do not consider sexual health to be a luxury—I consider it a biomarker.
Along with body composition, inflammatory markers, insulin sensitivity, hormone levels, and cardiovascular testing, I routinely discuss libido and sexual function with my patients. These conversations often reveal issues that laboratory testing alone cannot identify.
Loss of sexual interest may indicate testosterone deficiency, estrogen deficiency, thyroid dysfunction, chronic stress, depression, medication side effects, poor sleep, or relationship strain. Addressing these underlying causes frequently improves not only sexual wellness but overall health and vitality.
A Comprehensive Approach
Hormones are only one piece of the puzzle.
Healthy blood flow, regular exercise, strength training, restorative sleep, proper nutrition, stress management, and meaningful relationships all contribute to sexual wellness. Improvements in these areas often enhance both quality of life and long-term health.
This is why sexual health should never be treated as an isolated symptom. Instead, it should be viewed as one of the body’s most meaningful indicators of overall physiological resilience.
The Well-Lived Life
One reason my wife, Dr. Cristina Romero-Bosch, and I created The Longevity Protocol™ was to move beyond simply preventing disease.
Living longer has little value if we lose the experiences that make life meaningful. Our philosophy has always centered on the art and science of living the well-lived life. That includes maintaining the energy, strength, cognitive function, and vitality to fully enjoy meaningful relationships—including physical intimacy—with the person you love.
Sexual wellness is not separate from longevity. It is one expression of a healthy body and a fulfilling life.
The Take-Home Message
This study should not be interpreted to mean that increasing sexual frequency alone will extend lifespan. Observational research cannot prove cause and effect, and healthier individuals may naturally be more sexually active.
Nevertheless, the findings are compelling. Regular sexual activity was associated with lower cardiovascular risk and lower all-cause mortality, with the greatest observed benefit occurring at approximately one to two times per week.
For me, the most important lesson is that sexual health is an integrated reflection of hormonal balance, cardiovascular fitness, metabolic health, emotional well-being, and relationship quality. If libido declines or sexual function changes, don’t simply accept it as part of aging. Instead, view it as valuable clinical information and an opportunity to evaluate your overall health.
True longevity is not simply about adding years to life. It is about preserving the vitality, connection, and purpose that make those years worth living. Sexual wellness is one important part of that larger picture.
