Teacher Sleep Problems and Insomnia: Why School Follows You to Bed, and What Helps

It is 3:40 in the morning and you are awake again. Not because anything happened, but because your mind has picked up exactly where the school day left off: the parent email you have not answered, the lesson that fell apart in fourth period, the student who seemed off and you are not sure why. Your body is exhausted. Your thinking is still in the building.

If that is familiar, it is not a sign that you are bad at switching off. The research on work and sleep suggests it is a common response to the way teaching is structured, and there are things that tend to help.

A note before going further. This page is educational information, not medical advice, and it is not a substitute for care. Sleep problems can have many causes, including medical ones, and only a licensed health care provider who knows your situation can assess what is behind yours.

How Much Sleep Adults Need, and How Many Get It

According to the CDC, adults aged 18 to 60 are recommended to sleep at least 7 hours each night. In its analysis of 2014 national survey data, 65.2% of adult respondents reported getting that much, and more than one third reported typically sleeping less. The same report notes that sleeping under 7 hours is associated with increased risk for a range of health problems, including frequent mental distress. Those figures describe all U.S. adults rather than teachers specifically, but they make one thing clear: if you are short on sleep, you are far from alone.

Why Teaching Keeps You Up

The school day never really finishes. There is always another set of papers, another email, another student to think about. Researchers studying the link between unfinished tasks and sleep followed 59 employees across 12 weeks of Fridays and Mondays. More unfinished tasks at the end of the week went with more impaired sleep on the weekend, and the connection ran through affective rumination — replaying work with negative feeling. Problem-solving pondering, thinking constructively about how to handle something, did not carry the same effect. Unfinished tasks that piled up over the three months were also related to worse weekend sleep.

That distinction matters. Thinking about school in the evening is not automatically the problem. Going over the same worry again and again, with the feeling attached, is.

Research on teachers shows the same pattern. In a study of 143 primary and secondary school teachers, participants recorded their work-related thoughts every hour from 5 p.m. until bedtime. Teachers under high job strain took longer to unwind and ruminated more about work across the whole evening, including at bedtime. They did not sleep fewer hours than low-strain teachers, but they reported poorer sleep quality. A diary study of 74 beginning teachers found that afternoon fatigue and unfinished tasks each helped explain evening rumination. Teachers who generally ruminated more also tended to feel less energized the next morning, though that link did not hold from one day to the next.

How sleep feels matters, not only how long it lasts. In a study of 76 Finnish primary school teachers, non-restorative sleep, the kind you wake from still tired, partly explained the link between an imbalance of effort and reward at work and both burnout and exhaustion. The study was small and captured a single point in time, so it shows association rather than cause.

How Poor Sleep Connects to Burnout and Mood

A two-year study of 388 working adults looked for early risk factors for clinical burnout. Too little sleep, under six hours, emerged as the main risk factor, even after accounting for work demands and thinking about work during leisure time, both of which also predicted burnout. The authors saw a possible chain of causation. The important caveat is that only 15 people in the sample developed clinical burnout, so the finding is a signal rather than a settled answer.

Sleep is tied up with mood as well. A systematic review of nine studies, most of them longitudinal concluded that the best available evidence suggests insomnia is related to anxiety and depression in both directions, while noting that the small number of studies limits firm conclusions. In practice, poor sleep can be both a result of a hard stretch and something that makes the next stretch harder. Our guides to teacher anxiety and emotional exhaustion look at those experiences in more depth.

Seven Things That Tend to Help

None of these will fix a workload that is too large, and none is a treatment for a sleep disorder. They are the everyday habits that public health guidance and research support, adapted to the shape of a school week.

When It Is More Than a Few Bad Nights

The National Heart, Lung, and Blood Institute describes two kinds of insomnia. Short-term insomnia may be caused by stress or changes in your schedule or environment and can last a few days or weeks, which covers many hard patches in a school year. Chronic insomnia occurs three or more nights a week, lasts more than three months, and cannot be fully explained by another health problem.

You do not need to wait three months to ask for help. The National Institute of Mental Health advises seeking professional help if you have severe or distressing symptoms that have lasted two weeks or more, and it lists difficulty sleeping first, alongside difficulty concentrating, loss of interest in things you usually enjoy, and irritability. NIMH suggests starting with a primary care provider, who can refer you to a qualified mental health professional.

It is also worth knowing that effective treatment exists. The American College of Physicians’ clinical practice guideline recommends cognitive behavioral therapy for insomnia, or CBT-I, as the initial treatment for chronic insomnia disorder in adults. NHLBI describes CBT-I as a 6- to 8-week treatment plan that can be done by a doctor, nurse, or therapist, in person, by telephone, or online. Whether it or anything else is right for you is a decision for you and a provider. NHLBI also advises talking to your doctor before taking over-the-counter sleep products, and to your provider before using dietary supplements.

If sleep problems are arriving alongside a low mood that will not lift, our page on teacher depression describes what that can look like in a school context and where to get help.

What Schools and Districts Control

Much of what keeps teachers awake is set above the classroom. RAND’s 2025 report on teacher work-life balance found that a lack of job flexibility and increased intrusion of work into home life were each highly correlated with poor well-being for teachers. Evening email expectations, grading timelines that assume nights and weekends, and last-minute requests all push work into the hours meant for recovery.

The National Institute for Occupational Safety and Health has long held, in STRESS...At Work, that a combination of organizational change and stress management is the most useful approach to job stress, with organizational change given top priority. Sleep advice for individual teachers is the second half of that sentence, not the first. Leaders working on the structural side can start with educator wellness programs.
