Sleep Across Ages: Teen Routines, Adult Needs & Aging
Sleep questions change when the person asking is a teenager, a working adult, or someone noticing changes with age. This collection separates those settings rather than presenting a single routine as a solution for everyone. Use the adult-needs guide for the general hours-and-quality question, the teen article for school and schedule context, and the aging article for questions worth discussing with a clinician. An age category cannot explain every symptom or establish that a persistent change is harmless. The full articles preserve the difference between general sleep information and an assessment of a particular person's health and circumstances.

Key distinctions
- Adult guidance should not automatically become a teen sleep prescription.
- Time asleep and sleep quality are related but different questions.
- A change associated with aging is not an explanation for every new symptom.
How should adults think about sleep hours and sleep quality?
CDC lists 7 or more hours each day for adults ages 18 to 60, 7 to 9 hours for ages 61 to 64, and 7 to 8 hours for adults 65 and older. These are population-level recommendations, not a score that can diagnose a sleep disorder or determine exactly what one person needs.
Sleep health is not only the number of hours. CDC describes quality sleep as uninterrupted and refreshing, and suggests noticing patterns such as waking during the night, trouble getting up, or relying on naps. Daytime energy and function can also help you describe what is happening.

What sleep-routine issues arise around school and screens for teens?
Adolescents aged 13 to 18 need about 8 to 10 hours of sleep each night, according to the American Academy of Sleep Medicine guidance summarized by CDC. Sleep supports physical and mental health, attention, learning, and safety. Yet school start times, homework, work, activities, and later bedtimes can make a sufficient sleep window difficult.

Which sleep changes with age are worth discussing with a clinician?
The Sleep Medicine Clinics review describes age-related changes that can include earlier sleep timing. Sleep can also become lighter or include more awakenings. These changes do not mean that ongoing exhaustion or severe insomnia should simply be accepted as inevitable.
Adults still generally need a similar amount of sleep as they age. Individual needs vary, and sleep quality matters alongside time in bed.
