Sleep hygiene refers to habits that support quality rest. Practices like keeping a consistent bedtime, limiting caffeine, reducing screen time, and creating a calm environment improve sleep quality. Adequate rest restores brain function, regulates mood, and boosts concentration. Poor sleep, however, increases irritability, stress, and risk of depression. By prioritizing healthy sleep routines, individuals build resilience and emotional stability, strengthening overall mental health. https://www.delhimindclinic.com/
