Sleep and Mental Health

← Back to Toolkit

Sleep is one of the strongest predictors of mental well-being. Poor sleep is linked to higher risk of depression, anxiety, and relapse.


Why Sleep Matters

  • Regulates mood and emotional stability
  • Supports learning, memory, and concentration
  • Restores immune and metabolic systems

Even a single night of poor sleep can increase irritability and stress reactivity. Chronic disruption raises the risk of depression, anxiety, and burnout.


Practical Tips

  • Aim for 7–9 hours per night
  • Keep a consistent sleep schedule, even on weekends
  • Make the bedroom cool, dark, and quiet
  • Limit caffeine and screens in the evening

When to Seek Help

Persistent insomnia can often be improved with cognitive behavioral therapy for insomnia (CBT-I) — the gold standard, more effective long term than sleeping pills.

If poor sleep is worsening mental health, ask a clinician about targeted treatment.
