YOUR QUESTION. A CLEARER NEXT STEP.
What makes nightmares and night terrors worse in a child?
Nightmares and night terrors in children tend to worsen with overtiredness, irregular bedtimes, stress, illness, fever, caffeine, and scary or screen-based stimulation before bed. A calm, predictable, screen-free wind-down and consistent earlier bedtime help most. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

When the night feels like a frightening place, small changes to your child's day can help calm what unfolds after dark.
In short
Nightmares and night terrors usually get worse when a child is overtired, stressed, unwell, or kept to an irregular sleep routine. Too little sleep, big changes at home or school, screens or scary stories close to bedtime, a fever, or a too-busy, unpredictable evening can all increase how often and how intensely they happen. The good news: most settle on their own as your child grows, and gentle, steady routines make a real difference.
What tends to make them worse
- Not enough sleep — overtiredness is one of the biggest triggers, especially for night terrors. A child who is sleep-deprived spends more time in the deep sleep where terrors arise.
- Irregular bedtimes — chopping and changing when your child goes to bed and wakes unsettles the sleep cycle.
- Stress and big changes — starting school, a new sibling, moving home, family tension or worry can stir up nightmares.
- Scary or stimulating input before bed — frightening shows, stories, video games or rough-and-tumble play close to sleep time.
- Being unwell — fever, illness, pain or a full bladder can disturb deep sleep and bring on night terrors.
- Screens and bright light late — they delay sleep onset and reduce restful sleep.
- Caffeine — fizzy drinks, chocolate or tea later in the day can fragment sleep.
A calm, predictable, screen-free wind-down and a consistent earlier bedtime are the most powerful first steps — many families see fewer episodes within a few weeks.
When to seek a check
Most nightmares and night terrors are a normal part of growing up. Do seek a check if episodes happen most nights, last a long time, involve unusual or repetitive movements, cause daytime sleepiness or distress, continue well into older childhood, or if your child seems to stop breathing or snores heavily in sleep — these may point to something a clinician should review.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for episodes most nights, very long or intense terrors, unusual repetitive movements, daytime sleepiness, heavy snoring or pauses in breathing, or distress that continues into older childhood — these warrant a clinician's review.
In everyday life
Keep a calm, screen-free wind-down for the hour before bed and an earlier, consistent bedtime — overtiredness is one of the biggest triggers for night terrors.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Can being overtired cause night terrors?
Yes. Overtiredness is one of the most common triggers, especially for night terrors, because a sleep-deprived child spends more time in the deep sleep where terrors arise. An earlier, consistent bedtime often reduces episodes.
Do screens before bed make nightmares worse?
They can. Bright screens delay sleep onset and reduce restful sleep, and frightening or stimulating content close to bedtime can feed into nightmares. A calm, screen-free wind-down helps.
When should I worry about my child's night terrors?
Seek a check if episodes happen most nights, are very long or intense, involve unusual movements, cause daytime sleepiness, or if your child snores heavily or seems to stop breathing in sleep.
