Sleep is essential for physical and mental health, helping with body recovery, strengthening the immune system, and memory consolidation.

Most adults need 7-9 hours of sleep per night to function properly. Teenagers need 8-10 hours, and children need 9-11 hours.

Maintain a regular sleep routine, avoid caffeine and screens before bed, create a dark and quiet environment, and exercise regularly.

Sleep hygiene refers to habits and practices that help improve sleep quality, such as maintaining regular schedules, avoiding stimulation before bed, and creating an environment conducive to sleep.

Fatigue, irritability, difficulty concentrating, daytime sleepiness, and mood changes are common signs of sleep deprivation.
