A Gottman Institute report says teenagers ages 13 to 18 should regularly get eight to ten hours of sleep and describes research linking sleep with adolescent brain development. Evidence about how sleep affects long-term outcomes in humans is still developing, so the report recommends families plan schedules around adequate rest without presenting the research as proof of specific future effects.
The Gottman Institute has published guidance urging families to plan teenagers’ schedules around adequate sleep, citing recommendations that 13- to 18-year-olds regularly get eight to ten hours a night and research connecting sleep with brain development. The report says the precise long-term effects of disrupted sleep on human brain development are not yet established.
The report describes adolescence as a period of substantial brain reorganization. Two processes it identifies are synaptic pruning, in which some connections between nerve cells are eliminated as networks develop, and myelination, in which nerve fibers gain insulation that helps signals travel more efficiently. Researchers are investigating how sleep relates to these changes; the report does not say that every detail of the process is settled.
As one example, it refers to research in adolescent mice in which scientists repeatedly photographed small structures on nerve cells. They observed a net increase in those structures after waking and a net decrease after sleep, changes associated with pruning. The animal study offers evidence about a possible biological process, but it does not by itself establish the same effects or long-term outcomes in teenagers.
The report also cites a 2022 research review by neuroscientist Paul Anastasiades and colleagues on sleep and maturation of the prefrontal cortex, a region involved in planning, decision-making and regulating emotions. The review discussed how disrupted sleep could interfere with developing brain networks and potentially affect mental health later in life. The Gottman report says researchers still need to establish how such effects unfold over time in humans. It also notes that children release much of their growth hormone during sleep.
Sleep Shapes Teenagers’ Daily Schedules
The guidance matters to families because sleep competes with commitments they often see as investments in a teenager’s future: schoolwork, activities, jobs and time with friends. The report challenges the idea that late nights are necessarily evidence of dedication. It argues that sleep deserves to be considered alongside those waking-hour demands, while stopping short of claiming that a particular bedtime guarantees better mental health or academic results.
Sleep can also affect the immediate rhythm of family life: when a teenager is able to wake, how much time remains for homework and whether evenings become a source of conflict. The report recommends counting backward from the required wake-up time before adding commitments. For example, if a teenager must wake at 6:30 a.m., nine hours of sleep would mean being asleep by 9:30 p.m.; time to wind down would need to be allowed before that.
That calculation is a planning example, not a promise that every adolescent can fall asleep on command. The report recognizes that puberty naturally shifts teenagers toward feeling sleepy later. Its practical message is to plan collaboratively, identify barriers and reconsider demands that leave too little time for rest.

Puberty Can Shift Sleep Timing
The report frames sleep as both a family-scheduling issue and a developmental one. A teenager may be tired yet find an early bedtime difficult because sleep timing shifts during puberty. That can make a simple instruction to “go to bed earlier” less workable than a conversation about school start times, evening activities and routines.
The article advises parents to ask what is keeping a teenager awake. If assignments regularly extend late into the night, it suggests discussing workload and available support with teachers. Families can also review late practices or work shifts and agree on when gaming should stop, notifications should be silenced and phones put away. The report recommends involving teenagers in designing those routines and having adults avoid late household requests or difficult conversations just as bedtime approaches.

Long-Term Human Effects Remain Open
The report describes evidence linking sleep with brain maturation, but it does not establish that disrupted sleep causes specific long-term mental-health outcomes in teenagers. It explicitly says more research is needed to determine how potential effects unfold in humans. The mouse findings concern animal brain structures, and the 2022 review examined a body of evidence rather than reporting a definitive outcome for every teenager.
The source material does not provide study sample sizes, effect estimates or a single measure of how much sleep disruption changes later outcomes. It also does not identify a publication date for the guidance. The recommendation of eight to ten hours is presented as regular sleep guidance for ages 13 to 18; individual circumstances and the practical barriers a teenager faces are not resolved by the range alone.

Families Can Review Evening Demands
The report’s next steps are practical rather than tied to a new research milestone: families can calculate sleep time from the required wake-up hour, allow for winding down, and review homework, practices and work shifts that push bedtime later. Where assignments repeatedly run late, the report suggests parents contact teachers about workload and support.
It also recommends agreeing on an evening routine with the teenager, including when to stop gaming and put away a phone, while adults adjust their own requests and conversations. Further research will be needed to clarify the long-term relationship between sleep and human adolescent brain development; the source provides no timeline for that work.

Key Questions
How much sleep does the report recommend for teenagers?
The Gottman Institute report says teenagers ages 13 to 18 should regularly get eight to ten hours of sleep.
Does the report prove that sleep loss causes later mental-health problems?
No. It describes research suggesting disrupted sleep could affect developing brain networks, but says researchers still need to establish how possible long-term effects unfold in humans.
Why might a teenager struggle to fall asleep early?
The report says puberty naturally shifts teenagers toward feeling sleepy later. It recommends discussing routines and schedule pressures rather than assuming that an earlier bedtime is easy to achieve.
What can parents do if homework regularly keeps a teenager up?
The report suggests asking what is delaying sleep and speaking with teachers about workload and available support if assignments repeatedly run late. Families can also review evening activities and work shifts.
