If you work nights, rotating shifts, or very early starts, you've probably been told to "just get used to it." For a lot of people that never really happens. Their body keeps insisting it should be asleep at 3 a.m. on the job and awake at noon in bed. This week the American Academy of Sleep Medicine (AASM) published a clinical practice guideline focused specifically on shift work disorder. It builds on the academy's earlier, broader advice on body-clock disorders, but grades the evidence for this condition specifically. That gives clinicians, and the people they treat, a clearer menu of options.
What shift work disorder actually is
Feeling worn out after a run of night shifts isn't the same as having a sleep disorder. According to the AASM, shift work disorder applies when a required work schedule has overlapped with your normal sleep time for at least three months, and you have excessive sleepiness, insomnia symptoms, or both as a result. The root problem is twofold: your internal body clock is out of step with your hours (circadian misalignment), and you're usually not getting enough sleep.
It isn't rare. The AASM estimates it affects about 27% of adult shift workers, meaning roughly one in four people working nonstandard hours. The academy notes it turns up regularly in both primary care and sleep clinics. It can easily go unrecognized when sleepiness on the night shift is written off as part of the job.
What the new guideline recommends
The guideline appeared in the Journal of Clinical Sleep Medicine on October 24, 2026, along with a separate systematic review and meta-analysis of the underlying studies. It was written by an AASM task force led by co-author Kenneth P. Wright, Jr., with a dozen sleep medicine clinicians and researchers. The draft went out for public comment before the AASM board approved it. Every recommendation uses the word "suggests," which in guideline language means a conditional recommendation, not a firm rule. The recommendations fall into three groups.
1. For sleepiness on the job
- Modafinil or armodafinil. These prescription wake-promoting drugs had the strongest support, backed by moderate-certainty evidence for improving alertness during night shifts.
- Caffeine, used deliberately. Caffeine alone, caffeine combined with bright light, and a planned nap paired with caffeine are all options to consider. The evidence here is low-certainty, and the AASM notes the benefit varies from person to person.
- Bright light and meal timing. Scheduled bright light exposure and adjusting when you eat are listed as clock-based options, also with low-certainty evidence.
2. For trouble falling or staying asleep
- Cognitive behavioral therapy for insomnia (CBT-I). The same non-drug therapy that's first-line for ordinary insomnia is suggested for shift workers. (We looked at a recent trial of CBT-I in our post on CBT-I and biological aging.)
- Melatonin or melatonin receptor agonists. Both are suggested to help with sleep at unusual hours. See our explainer on how melatonin regulates sleep for why timing matters with this hormone.
- Some sleeping pills, but not others. Certain hypnotics are suggested to help people sleep around their schedule. The guideline recommends against hypnotics with poor risk-benefit profiles, specifically naming some benzodiazepines.
3. For shifting the body clock
- Timed bright light to nudge the circadian system toward your working hours.
- A consistent sleep schedule where your rota allows it.
- Filtering light on the commute home, such as wearing dark or light-filtering glasses after a night shift so morning sunlight doesn't tell your brain the day has started.

Why this matters more than it might seem
Most shift-work sleep advice online is a list of tips with no indication of which ones have evidence behind them. The useful thing about this guideline is that it separates the options by evidence quality. Prescription wakefulness drugs had the strongest support for on-shift alertness. Caffeine, naps, light and meal timing are reasonable to try, but the research behind them is thinner. That doesn't mean they don't work. It means the studies are smaller or less consistent, so expect to experiment and find what works for your body and your schedule.
Two points stand out to us. First, the guideline treats sleepiness and insomnia as separate problems with different fixes. Someone who nods off at 4 a.m. but sleeps fine at home needs a different plan from someone who is alert at work but lies awake in a sunlit bedroom at 10 a.m. Second, the warning about some benzodiazepines matters. Older sleeping pills are still widely prescribed, and the risk of grogginess the next day is especially serious for people who drive home at dawn or work in safety-critical jobs.
The task force also stressed that the evidence for many treatments is limited. Its message is that there's no single fix. "There is no one-size-fits-all solution for shift work disorder," Wright said in the AASM's announcement. Treatment is meant to be matched to your symptoms, your schedule, and what you're willing to try.
Practical steps you can start with
- Track your symptoms first. Note when you feel sleepiest, how long you sleep after shifts, and how long it takes to drop off. That record tells a clinician whether sleepiness, insomnia, or both is the main issue.
- Make your daytime bedroom truly dark. Blackout curtains, an eye mask, and earplugs or white noise help protect daytime sleep. Our guide to creating a relaxing sleep environment covers the basics.
- Manage light on both ends. Bright light early in your shift and less light on the way home is the core of the clock-shifting advice. Our post on how light affects your sleep explains why.
- Time caffeine and naps deliberately. Use caffeine early in the shift rather than in the last few hours, and consider a short planned nap before or during work if your job allows. We cover nap length in our article on the benefits of napping.
- Don't self-prescribe. Modafinil, armodafinil, melatonin receptor agonists, and hypnotics are medical decisions. If tips aren't enough after a few months of shifts, ask your doctor specifically about shift work disorder and mention this guideline.
Key takeaways
- The AASM has published an evidence-graded clinical guideline specifically for shift work disorder, which affects about 27% of adult shift workers.
- For on-the-job sleepiness, modafinil or armodafinil had the best evidence. Caffeine, light, naps, and meal timing are lower-certainty options.
- For sleep problems, CBT-I, melatonin or melatonin receptor agonists, and certain hypnotics are suggested. Some benzodiazepines are suggested against.
- Timed bright light, a steady sleep schedule, and filtering light on the commute home can help realign the body clock.
- The overall message is individualized care: no single treatment works for everyone.
If you've spent years assuming exhaustion is simply the price of working nights, this guideline gives you a reason to raise it with your doctor. It also gives them a structured, evidence-based list of treatments to work from.
