The Short Version
Weekly sexual activity is associated with some better mental health markers in certain populations, but the claim overstates the evidence by using causal language ("produces") when the research is largely observational and correlational. A major systematic review flags contradictory findings, confounding bias, and population-specific effects. Physical health benefits are inconsistently supported — some longitudinal data actually links higher sexual frequency to increased cardiovascular risk in older men. The evidence does not support a blanket causal claim across both physical and mental health.
