Sleep is essential for overall health and well-being. It plays a crucial role in physical health, cognitive function, and emotional stability. During sleep, the body repairs tissues, strengthens the immune system, and consolidates memories. Adequate sleep helps improve concentration, productivity, and mood, while insufficient sleep is linked to increased risks of chronic conditions such as heart disease, diabetes, obesity, and mental health disorders.
Adults typically need 7-9 hours of quality sleep each night, while children and teenagers require more. Maintaining good sleep hygiene—such as keeping a consistent sleep schedule, creating a comfortable sleep environment, and limiting exposure to screens before bedtime—can promote better sleep health.
