Self-reported insomnia in young men is a significant predictor of clinical depression and psychiatric distress decades later, independent of other risk factors.
If you struggle with insomnia, treat it as a serious warning sign for future mental health, not just a nuisance. The risk for depression persists for decades. Prioritize sleep hygiene and seek professional help for sleep disturbances early, as they are a strong predictor of future psychiatric distress.
GoodSupportsHIGH confidence
These findings suggest that insomnia in young men is indicative of a greater risk for subsequent clinical depression and psychiatric distress that persists for at least 30 years.
