A recent study has found that maintaining a regular sex life could be a significant factor in supporting mental health and lowering the risk of depression. Published in the Journal of Affective Disorders in April 2025, the research explored the relationship between sexual activity and mental well-being across a diverse group of over 14,000 adults in the U.S., aged 20 to 59.
The findings revealed that individuals who engaged in sexual activity at least once per week were about 24% less likely to show symptoms of moderate to severe depression compared to those who had no sex in the preceding month. Interestingly, the optimal frequency appeared to be between one and two times per week. Beyond this range, the benefits appeared to level off, suggesting that more frequent sex didn’t necessarily lead to further improvement in mental health.
What makes this study compelling is its broad demographic base, confirming that the association between sex and reduced depression risk holds true regardless of age, physical health, marital status, or income. The mental health benefits were found to be most pronounced in younger adults, particularly among Mexican American and non-Hispanic White participants.
Although the research does not claim that sex directly prevents depression, it highlights the mutual influence between emotional well-being and sexual activity. Physical intimacy can trigger the release of endorphins—natural mood enhancers—and foster emotional bonding, which in turn may help ease anxiety and stress. In essence, a healthy sex life may not be a cure for depression, but it certainly plays a positive role in promoting emotional stability and overall well-being.
