Most adults need between 7 and 9 hours of sleep per night for optimal health.
Sleep needs vary by age: teenagers typically need 8-10 hours, adults 7-9 hours, and seniors (65 and older) usually do well with 7-8 hours. Individual needs can vary, but consistently getting less than 7 hours has been linked to various health issues.
Beyond just the number of hours, maintaining a consistent sleep schedule—going to bed and waking up at roughly the same times each day—is important for good sleep quality.
