Night terrors in children are terrifying to watch. Your child screams. Their eyes are wide open. They thrash around. When you reach out to comfort them, they resist and pull away. They do not seem to see you at all.
And the next morning, they remembered nothing.
Night terrors affect approximately 1 to 6 percent of children in the
United States, according to the American Academy of Sleep Medicine. They are most
common between ages 4 and 12, with a significant number of cases occurring in
the 6 to 10 age range. They are alarming for parents, but in most cases, they
are medically harmless to the child.
Understanding what is happening, why it happens, and what to do in the
moment changes everything. This guide
equips you with everything you need.
Night Terrors in Children: What Are They and How Are They Different from Nightmares?
Night terrors in children are not the same as nightmares. “This is the key point you need to grasp. And most parents
confuse them.
A nightmare is a bad dream. Your child wakes up. They are scared.
They can tell you what happened in the dream. They want comfort, and they can
receive it. They remembered it the next morning.
A night terror is completely different. Your child does not wake up. They
remain in a state of partial sleep. Their eyes may be open, and they may
scream, thrash, sit up, or even walk. But they are not awake, and they cannot be
comforted the way an awake child can be. In the morning, they have no memory of
the episode at all.
This is a critical distinction. It tells you not to try to wake your
child during a night terror. It tells you why your attempts to comfort them in
the moment seem to make things worse. And it removes the fear that your child
is experiencing psychological trauma from the event itself.
What Causes Night Terrors in Children?
They are a sleep cycle phenomenon
Night terrors happen during a specific stage of sleep called slow wave
sleep, also known as deep sleep or stage 3 non-REM sleep. They typically occur
in the first third of the night when this deep sleep is most concentrated.
During a normal transition out of deep sleep, the brain briefly surfaces
toward lighter sleep. In children who experience night terrors, the brain gets
stuck mid-transition. Part of the brain activates, triggering movement and
emotional responses, while another part remains deeply asleep. The result is
the terrifying combination of apparent wakefulness and complete
unresponsiveness.
This is a neurological event, not a psychological one. There is no
evidence that night terrors are caused by emotional trauma or indicate deeper
mental health problems in most children.
Sleep deprivation is the biggest trigger
The single most consistent trigger for night terrors in children is
insufficient sleep. When a child does not sleep enough, they spend more time in deep slow
wave sleep as the body tries to recover. More time in deep sleep means more
opportunities for that incomplete awakening to occur.
The Centers for Disease Control and Prevention recommends 9 to 12 hours
of sleep per night for children aged 6 to 12. Many American children regularly
get significantly less than this, particularly when devices are present in
bedrooms.
If your child is experiencing frequent night terrors, the first place to
look is whether they are consistently getting enough sleep each night.
Other Common Triggers
Beyond sleep deprivation, several other factors can increase the
frequency of night terrors:
- Fever or
illness, which disrupts normal sleep architecture
- Stress or
anxiety during the day, which can intensify slow wave sleep
- A change in
schedule, such as a new school year, travel across time zones, or a
change in bedtime routine
- Sleeping in an
unfamiliar place, such as a hotel or grandparent's home
- Caffeine, even in small
amounts from sodas or energy drinks
- Sleep apnea is a disorder in which breathing pauses briefly during sleep
If night terrors have recently started or significantly increased in
frequency, think about what has changed in your child's sleep environment,
schedule, or health.
Night Terrors in Children: What Does an Episode Actually Look Like?
The typical night terror episode occurs 1 to 3 hours after your child
falls asleep. It comes on suddenly. Your child may sit up, scream, cry, or moan
loudly. Their eyes are often open, but they look right through you. They may
thrash or kick. Their hearts may be racing, and they may sweat.
Most episodes last between 5 and 20 minutes. After the episode, the child
usually settles back into sleep naturally. They do not wake fully, and they
have no memory of the event in the morning.
This is almost the reverse of a nightmare. The child
experiencing a nightmare wakes up, is upset, can be comforted, and remembers.
The child having a night terror stays asleep, cannot be effectively comforted,
and remembers nothing.
What Should You Do During a Night Terror?
The most important rule is this: do not try to wake up your child. Waking a child
during a night terror almost always makes the episode longer, more distressing,
and more confusing for the child. They may become genuinely disoriented and
frightened if pulled out of that in-between state suddenly.
Here is what to do instead:
Stay present and stay calm. You cannot comfort your child in the
traditional sense, but your calm presence in the room helps keep the
environment safe.
Make sure they are physically safe. Move any objects they could hurt
themselves on. If they try to get out of bed or walk, gently guide them back
without restraining them firmly.
Do not restrain them forcefully. Holding them down tends to intensify
the thrashing and distress of the episode. Gentle guidance is far more
effective.
Do not try to explain or reason with them. They cannot process
what you are saying. They are not awake.
Do not turn on bright lights. This can intensify disorientation. A
low-level nightlight or a dim light in the hallway is sufficient.
Wait it out. Most episodes end within 20 minutes, and the child returns to normal
sleep on their own. After the episode passes, stay nearby briefly and then let
them sleep.
What about after the night terror?
In the morning, do not tell your child what happened. There is no
developmental or therapeutic benefit to explaining a night terror to a child
who has no memory of it. In many cases, telling a child they screamed and
thrashed in the night creates anxiety about going to sleep the next night.
If your child asks, keep it brief and neutral. "You had a restless night,
but you are completely fine." That is all they need to know.
You, however, may not be fine. Night terrors are much more
distressing for the parent than for the child. This is worth knowing. Your
child is not suffering during the episode. Their experience is more like a
glitch in the transition between sleep stages than a nightmare experience.
Night Terrors in Children: How to Reduce Their Frequency
Fix sleep before anything else
Protecting and improving your child's total sleep time is the most
effective intervention available. Set a consistent bedtime. Keep
devices out of bedrooms. Create a calm 30-minute wind-down routine before bed.
Even adding 30 to 45 minutes of sleep per night can significantly reduce
the frequency of night terrors in mildly sleep-deprived children.
Keep the bedtime routine consistent
Predictability is protective. A consistent pre-sleep routine, the
same sequence of events each night, helps the brain transition into sleep more
smoothly. Disruptions to routine are a known trigger.
This means keeping bedtime and wake time consistent, even on weekends. The
social jet lag created by staying up late on Fridays and Saturdays disrupts the
sleep architecture of the following week.
Manage Daytime Stress
Significant daytime stress can intensify night terrors. If your child is
going through something hard at school, in their friendships, or at home, that
stress may show up in their nights even if they cannot articulate it during the
day.
Talk gently about what is happening in their world. Look for patterns. Do
night terrors cluster around specific days or events? If stress seems to be a
consistent trigger, addressing the underlying daytime anxiety is as
important as improving sleep hygiene.
Scheduled Awakenings for Frequent Episodes
If your child's night terrors happen at a predictable time, a scheduled
awakening may help. This is a technique recommended by sleep specialists where a parent
gently rouses the child, just briefly and not fully, about 15 to 30 minutes
before the typical episode time.
This brief disturbance resets the sleep cycle and prevents the child from
entering the deep slow wave sleep phase where the night terror occurs. It does
not need to become a long-term habit. Following
a few weeks of regular, planned awakenings often leads to a marked drop in
episode frequency.
When Should You See a Doctor About Night Terrors?
Most night terrors in children resolve on their own as the brain matures. Many children who
experience them between ages 6 and 10 outgrow them entirely by early
adolescence.
See your pediatrician if:
- Episodes are
very frequent, occurring most nights or every night
- Episodes are
very long, lasting more than 30 minutes regularly
- Your child is
injured during an episode because of walking or thrashing
- The night
terrors are significantly affecting your child's daytime functioning because of poor sleep
- You suspect sleep
apnea based on snoring or breathing pauses during sleep
- Your child has
memory of distressing content that suggests the episodes may be nightmares
or something else
- The episodes started
suddenly in a child who previously did not have them and had no
identifiable trigger
Your pediatrician can refer you to a pediatric sleep specialist if
needed. Sleep studies, also called polysomnography, can identify whether
sleep apnea or another sleep disorder is contributing to the episodes.
The Bottom Line
Night terrors in children are frightening to witness and rarely dangerous
to the child experiencing them. Your child is not suffering in the way it
looks. They will not remember. And in most cases, with consistent sleep and
reduced triggers, the episodes become less frequent and eventually stop.
Start with sleep. Protect it like the health intervention it is.
Consistent bedtimes, no devices in bedrooms, and a calm pre-sleep routine are
your most powerful tools.
If night terrors are frequent, severe, or affecting your child's daytime
well-being, speak to your pediatrician. You do not need to manage this alone, and the right guidance makes a real difference. Trust what you are seeing and
take that next step.
