A daily health search — CDC-style ranges, not a one-night rule. This page has 50 important questions and answers. Original explainer for daily search — not a government login or live tracker.
Sleep need changes with age. Public-health ranges (such as those summarised by CDC / AASM) are bands, not exam marks: teens often 8–10 hours, most adults 7 or more, older adults still need about 7–8 but may sleep lighter. Newborns sleep many more hours in chunks.
One short night is not a disease. Weeks of 5-hour nights, loud snoring with gasping, or falling asleep at the wheel need a clinician, not only a quiz. Caffeine late, screens in bed, and shift work all shift the clock.
This is general education. Your doctor may set different goals if you have sleep apnea, depression, or a baby at home.
