- Disruptions to a child's sleep schedule — even positive ones like travel or holidays — can increase the frequency of night terrors.
- Recurring or severe night terrors may signal an underlying sleep disorder that warrants professional evaluation.

Night Terrors vs. Nightmares: Understanding the Difference
Before exploring what triggers night terrors in children, it helps to understand what they actually are — and what they are not. Night terrors and nightmares are often confused, but they are distinct events with different causes and characteristics.
| Feature | Night Terrors | Nightmares |
|---|---|---|
| Sleep stage | Non-REM (deep sleep) | REM sleep |
| Timing | Usually first third of the night | Usually second half of the night |
| Child's awareness | Appears awake but is not | Fully wakes up |
| Memory of event | Rarely any recall | Often remembers vividly |
| Comforting | Difficult to soothe | Child can usually be calmed |
Night terrors occur during the transition out of deep, non-REM sleep. A child may sit up, scream, thrash, or appear terrified — and yet remain asleep throughout the episode. According to the American Academy of Sleep Medicine, night terrors are classified as a type of parasomnia, a category of disruptive sleep-related events. They are most common between ages 3 and 12 and affect an estimated 1–6.5% of children.
Common Triggers of Night Terrors in Children
Sleep Deprivation
One of the most frequently overlooked triggers of night terrors is simply not getting enough sleep. When a child is overtired, the brain spends more time in deep, slow-wave sleep in an effort to recover — and it is precisely during this sleep stage that night terrors occur. Any factor that cuts into total sleep time, including a later-than-usual bedtime or skipped naps in younger children, can raise the likelihood of an episode.
Stress, Anxiety, and Emotional Overstimulation
Children process emotions differently than adults, and stressful experiences do not always surface in obvious ways. A difficult school day, family tension, a new sibling, or even an exciting event can manifest as nighttime disturbances. High levels of emotional arousal before bed — including vigorous play, screen time, or stimulating content — can make it harder for the brain to settle into the deep sleep stages without disruption.
Illness and Fever
Fever is a well-documented trigger for night terrors. When the body is fighting an infection, sleep architecture can shift dramatically, increasing the proportion of time spent in deep sleep and disrupting smooth transitions between sleep stages. Parents often notice that their child experiences night terrors during or shortly after an illness, even if the child seemed to recover quickly.
Irregular Sleep Schedules
The body thrives on routine. When a child's bedtime, wake time, or nap schedule changes frequently, the internal sleep clock — or circadian rhythm — can be thrown off. Travel across time zones, seasonal changes in daylight, or summer schedules that allow later bedtimes are all common culprits. Inconsistency in sleep timing can make the brain more vulnerable to arousal disturbances during deep sleep.
Sleep-Disordered Breathing
This is one of the triggers that parents most often miss. Obstructive sleep apnea and other forms of sleep abnormal breathing can cause repeated micro-arousals throughout the night that disrupt normal sleep architecture. Research has shown a meaningful association between sleep-disordered breathing and parasomnias, including night terrors, in children. When breathing is repeatedly interrupted during sleep, the brain may react with incomplete awakenings that present as night terror episodes.
Medications and Substances
Certain medications — including some antihistamines, stimulant medications, and sleep aids — can alter sleep structure in ways that increase parasomnia risk. If a child has recently started a new medication and begins experiencing night terrors, it is worth discussing with a healthcare provider.
When Do Night Terrors Signal Something More Serious?
Isolated night terrors are common and typically outgrown without intervention. However, certain patterns warrant professional evaluation:
- Episodes that occur multiple times per week
- Night terrors that persist beyond adolescence
- Behaviors during episodes that could pose a safety risk (running, leaving the room)
- Daytime sleepiness, behavioral changes, or difficulty concentrating
- Loud snoring, gasping, or observed pauses in breathing during sleep
These signs may indicate an underlying childhood sleep disorder that requires diagnosis and treatment. A board-certified sleep specialist can evaluate whether sleep-disordered breathing, a circadian rhythm issue, or another condition is contributing to the episodes.
Tips for Reducing Night Terrors at Home
While professional evaluation is important when episodes are frequent or severe, there are practical steps families can take to support better sleep at home:
- Prioritize consistent sleep and wake times, even on weekends and school breaks.
- Create a calming pre-bedtime routine that avoids screens, vigorous activity, and emotionally stimulating content for at least an hour before bed.
- Ensure adequate total sleep for your child's age — the American Academy of Pediatrics recommends 10–14 hours for preschoolers and 9–12 hours for school-age children.
- Keep the sleep environment cool, dark, and quiet.
- Avoid waking the child during an episode — it can prolong distress and confusion. Instead, stay nearby to ensure safety.
- Note patterns. Keeping a sleep diary can help identify specific triggers, which is also useful information when consulting a specialist.

Frequently Asked Questions
What are night terrors in children?
Night terrors are episodes of intense fear, screaming, or thrashing that occur during deep, non-REM sleep. Unlike nightmares, children are not fully awake during a night terror and typically have no memory of the episode afterward.
How are night terrors different from nightmares?
Nightmares occur during REM (dreaming) sleep, usually later in the night, and the child typically wakes up and remembers the dream. Night terrors happen earlier in the night during deep sleep, and the child remains asleep and unaware throughout.
What causes night terrors in children?
Common causes include sleep deprivation, illness, fever, stress, emotional overstimulation, irregular sleep schedules, and sleep-disordered breathing such as obstructive sleep apnea.
What are night terrors in children a sign of?
While most night terrors are benign and outgrown, frequent episodes can indicate an underlying sleep disorder, such as obstructive sleep apnea, a circadian rhythm disruption, or anxiety that warrants professional attention.
