Night terrors can often be reduced or eliminated by addressing their triggers, especially sleep deprivation, inconsistent sleep schedules, and underlying sleep disorders. About a third of children experience them, with peak prevalence at 18 months, and most outgrow them by their teenage years. For both children and adults, the most effective strategies focus on what happens before bed, not during an episode.
What Night Terrors Actually Are
Night terrors happen when the brain gets stuck between deep sleep and wakefulness. Unlike nightmares, which occur during dream sleep (REM) and are most common in the early morning, night terrors strike during the first half of the night, typically one and a half to two and a half hours after falling asleep. The person may scream, thrash, sit up, or even walk around, but they’re not conscious and won’t remember it afterward.
This distinction matters because it changes how you respond. Nightmares wake a person up and leave them shaken but aware. Night terrors look far more dramatic from the outside, but the person experiencing one has no recall of bad dreams. They’re not suffering the way it appears. The episode usually lasts a few minutes and ends on its own.
Common Triggers
Night terrors don’t have a single known cause, but several factors reliably increase the chance of an episode:
- Sleep deprivation. This is the most consistent trigger. A late bedtime, skipped nap, or disrupted schedule can be enough.
- Fever. Illness-related temperature changes commonly set off episodes in children.
- Stress and emotional tension. In adults especially, high stress or trauma is a frequent contributor.
- Obstructive sleep apnea. Breathing disruptions during sleep can trigger partial arousals that lead to night terrors.
- Restless legs syndrome. Another condition that fragments sleep and can provoke episodes.
- Alcohol use. Drinking disrupts normal sleep architecture and can trigger night terrors in adults.
- Family history. Night terrors are more common in people whose parents or siblings have experienced them or sleepwalking.
Identifying which of these applies to you or your child is the first step. A sleep journal tracking bedtimes, wake times, and episode timing can help you and a healthcare provider spot patterns.
Scheduled Awakenings
The most studied technique for stopping night terrors in children is called scheduled awakening. It works by gently disrupting the sleep cycle just before the brain would normally get stuck between stages.
Here’s how it works: track when night terrors typically occur over a week or two. Then, each night, briefly wake your child 15 to 30 minutes before that usual time. You don’t need to fully wake them. A light touch, slight repositioning, or quiet word that causes them to stir and resettle is enough. The goal is to reset the sleep cycle so it passes through that vulnerable transition smoothly.
In clinical use, this approach has proven remarkably effective. One study published in the Journal of Pediatric Psychology found that scheduled awakenings immediately eliminated episodes in all participating children, with zero occurrences across the full 28-day intervention period. Parents typically continue the technique for several weeks, then gradually stop. Many children don’t relapse.
Sleep Habits That Reduce Episodes
Because sleep deprivation is the most common trigger, building a consistent sleep routine is often enough to dramatically reduce night terrors on its own.
Set a consistent bedtime and wake time, including on weekends. For children, this also means protecting naps if they’re still at a nap-taking age. Even 30 minutes of accumulated sleep debt over several days can be enough to provoke an episode in a susceptible child.
Create a predictable wind-down routine before bed. This might include a warm shower, a story, or calm music. Avoid emotionally stimulating activities in the hour before sleep, including exciting TV, roughhousing, or outdoor play. Limit caffeine-containing foods and drinks in the afternoon and evening, which applies to older children and adults alike.
The sleep environment matters too. Keep the room at a comfortable temperature, minimize light with blackout curtains if needed, and consider white noise to mask disruptive sounds. Reducing screen time before bed helps, since blue light from phones and tablets can delay the onset of deep sleep. If screens are necessary, blue-light-filtering settings or glasses can help.
What to Do During an Episode
The hardest part of night terrors for parents and partners is watching them happen. Your instinct will be to grab the person, shake them awake, or try to comfort them. Resist that urge. Trying to wake someone during a night terror or physically restrain their movement typically makes the episode worse and last longer.
Instead, stay nearby and make sure they’re safe. Speak calmly if you want, but don’t expect a response. The episode will pass on its own, usually within a few minutes. Your job is simply to prevent injury.
Safety-proof the sleeping area ahead of time. Lock windows and exterior doors. Block stairways with a gate. Move electrical cords, sharp objects, and anything fragile out of reach. If your child sleeps in a bunk bed, move them to a lower bed. For adults who walk during episodes, consider putting bells or alarms on doors so a partner can follow and keep them safe.
Night Terrors in Adults
While night terrors affect roughly 34% of toddlers at their peak, they’re far less common in adults. When they do occur in adults, stress and psychological trauma are the most frequent drivers. Migraines, sleep apnea, and restless legs syndrome can also be involved.
Adults experiencing regular night terrors should look seriously at whether an underlying sleep disorder is contributing. Sleep apnea in particular is worth investigating, since treating the breathing problem often resolves the night terrors as a side effect. A sleep study can rule this in or out.
For stress-related night terrors, addressing the root cause through therapy, stress management, or lifestyle changes tends to be more effective than trying to treat the night terrors in isolation. Alcohol is worth examining too. Even moderate drinking close to bedtime can fragment sleep enough to trigger episodes in someone who is predisposed.
When Night Terrors Typically End
Most children outgrow night terrors. A large longitudinal study published in JAMA Pediatrics found that prevalence peaks at 18 months (affecting about 34% of children), remains above 40% after age 5, then drops significantly. By age 13, only about 5% of children still experience them. The trajectory varies, but the overall trend is strongly toward resolution without any specific treatment.
That said, frequent episodes that disrupt the household, cause injuries, or persist into the teenage years are worth discussing with a doctor. In some cases, an underlying condition like sleep apnea is keeping the cycle going, and treating it can bring relief quickly.
