Poor sleep also impairs attention, concentration, and problem-solving abilities. Quality sleep helps restore the brain’s chemical balance, essential for mental clarity. Ensuring good sleep hygiene is vital for mental resilience, emotional balance, and reducing the risk of developing mental health disorders.
