New findings published in the Journal of Affective Disorders indicate that engaging in sexual activity one to two times per week can cut the risk of moderate to severe depression by nearly 24%. Analyzing data from over 14,700 U.S. adults aged 20–59, scientists found that this “sweet spot” of intimacy triggers the release of mood-boosting hormones—oxytocin, dopamine and endorphins—offering powerful protection against depressive symptoms. PsyPost details the landmark study.

The large-scale Shantou University Medical College study—summarized by The Sun—confirmed that those reporting at least weekly intimacy were 24% less likely to score high on depression scales compared to those with less frequent encounters. Remarkably, extra sessions beyond two per week offered no further mood boost, suggesting a plateau effect at roughly 103 annual encounters.
Research highlighted by the Hindustan Times underscores how consistency matters: couples maintaining one to two intimate moments weekly saw the greatest jump in reported life satisfaction, while those with more sporadic patterns showed no clear advantage.

Scientists caution that the cross-sectional design cannot prove causation—depressed individuals may simply engage in less sex—but the robust correlation survived adjustments for age, health status, income and relationship length. Future longitudinal trials are planned to decode cause and effect.
Beyond mental well-being, the study echoes broader research on sex’s health perks: lower heart-disease risk, stronger immune response and improved sleep quality. As Dr. Li Chen, lead author, notes, “Regular, moderate intimacy may serve as an accessible, low-cost complement to traditional depression therapies.”
While prescription antidepressants help roughly half of patients, these new insights invite a more holistic approach: fostering healthy relationships, prioritizing physical connection and acknowledging sex as a vital pillar of mental health.
