Is Sex Actually Good for Your Health? What the Evidence Shows (and What It Doesn't)

Most data is observational — healthier people may have more sex, not the reverse. Few long-term trials exist. Definitions of “sexual activity” vary widely across studies.

• Mild exertion

  Sex raises heart rate similarly to moderate activity — usually safe if cleared for exercise.

Small studies link weekly activity to IgA levels; effect sizes are modest. No credible claim that sex prevents colds. Vaccines and handwashing still win.

• Hypertension, diabetes, obesity — manage medically
• Low desire from trauma, hormones, or medications — needs targeted care
• Avoiding sex due to pain or shame — that is the health issue to treat
