Neurologist Dr. Sudhir Kumar has outlined how much sleep the human body needs at different ages, stressing that sleep is vital for brain health, immunity, and overall well-being. From newborns needing up to 17 hours to adults requiring 7–9 hours, the recommendations highlight age-specific sleep needs for optimal functioning.
Sleep is not just rest—it is an active biological process where the body repairs tissues, balances hormones, and clears toxins. Dr. Sudhir Kumar, a Hyderabad-based neurologist, recently shared a detailed breakdown of age-wise sleep requirements, emphasizing that insufficient sleep can impair memory, immunity, and long-term health.
According to his guidance, newborns (up to 3 months) need 14–17 hours daily, while infants (4–11 months) require 12–15 hours. Toddlers (1–2 years) should get 11–14 hours, and school-age children (6–13 years) need 9–11 hours. Teenagers benefit from 8–10 hours, while adults (18–64 years) should aim for 7–9 hours. Seniors (65+) generally need 7–8 hours.
Experts caution that treating sleep as optional—often sacrificed for work or lifestyle—can lead to chronic fatigue, weakened immunity, and higher risk of neurological disorders.
