Mood, Health & Wellness Benefits

  • 24% Lower Depression Odds: Regular weekly activity is linked to a significant reduction in the odds of depression.
  • Hormone Boost: Each orgasm can trigger a spike in oxytocin (the "bonding hormone") and endorphins (natural mood lifters).
  • Stress Reset: It helps reset your stress response by suppressing or stabilizing cortisol levels.
  • Better Sleep: Orgasm-released prolactin can promote deeper, more restorative sleep.
  • Immune Support: Regular intimacy is correlated with higher levels of protective antibodies.
  • 10% Lower Heart-Disease Risk: For some patient groups, weekly activity has been linked to a lower risk of cardiovascular disease.

The Science Behind It

This calculator translates your activity into key health and wellness benefits based on findings from peer-reviewed medical literature. It provides a positive, holistic view of your sex life, highlighting metrics for calories, mood, immunity, and long-term health.

1. Calorie & Energy Expenditure

Sexual activity is a form of moderate-intensity exercise, with an energy expenditure of about 3.5 METs (Metabolic Equivalent of Task). Our calculations are based on studies showing that men burn approximately 4.2 kcal/minute and women burn 3.1 kcal/minute during partnered sex.

2. Hormonal & Mood Benefits

Orgasm triggers a surge in plasma oxytocin, the "bonding hormone," which promotes relaxation and social connection. Simultaneously, the brain releases endorphins, the body's natural pain-relievers and mood-lifters. This hormonal cascade also helps reset the stress response by stabilizing or decreasing cortisol levels.

3. Mental & Physical Health

Regular sexual activity is associated with significant health benefits. A large-scale spline model found that having sex at least once a week is linked to a 24% reduction in the odds of depression. Furthermore, studies on post-myocardial infarction patients show a 10% lower risk of heart disease for those engaging in weekly sexual activity.

4. Sleep & Immunity

The release of prolactin after orgasm can lead to deeper, more restorative sleep. On the immunity front, regular intimacy is correlated with higher levels of protective antibodies, which may result in fewer common colds.
