Sleep and Mental Health Are Intertwined

Does sleep quality affect psychological health and longevity?

Yes. Poor sleep increases risk of depression, anxiety, and dementia, while healthy sleep protects mental resilience and lifespan.

Explanation

Sleep deprivation raises cortisol, reduces serotonin, and impairs emotional regulation. Chronic insomnia is strongly linked to depression, anxiety, and cognitive decline. Conversely, restorative sleep supports brain plasticity, memory consolidation, and stress resilience.

Studies show that poor sleepers have higher mortality risk, even when controlling for other lifestyle factors. Cognitive behavioral therapy for insomnia (CBT-I) is highly effective in restoring sleep and improving psychological outcomes.

Practical Emphasis: Prioritize sleep hygiene — regular bedtimes, dark environments, and reduced evening screen exposure. Treat sleep as a cornerstone of both mental and physical longevity.

Takeaway (Action Tip)

Protect 7–9 hours of quality sleep to safeguard both brain and body.
