How Good Sleep Improves Your Mental Health

Sleep and mental health are deeply connected. During deep sleep the brain processes emotions, consolidates memory and clears metabolic waste, which is why a run of poor nights quickly shows up as irritability, anxiety and low mood. Adults need seven to nine hours of quality sleep. Keeping a fixed bedtime, dimming screens an hour before bed, avoiding late caffeine and keeping the bedroom cool and dark are simple habits that measurably improve sleep quality within two weeks. If insomnia persists for more than a month, or you snore heavily and wake up unrefreshed, speak to a doctor — treating the underlying sleep issue often lifts mood and focus more than any productivity trick.
