Night Terrors in Children with ASD

Night terrors are a type of sleep disturbance that commonly affects young children, particularly those between 18 months and 6 years old. Boys are slightly more likely to experience them. Children with Autism Spectrum Disorder (ASD) may face additional challenges with night terrors due to difficulties regulating their emotions and maintaining consistent sleep patterns. While night terrors can be distressing for both the child and the parents, they are generally not harmful and often decrease as the child grows older.

Understanding Night Terrors

Night terrors typically occur 2–3 hours after a child falls asleep during the transition from deep non-REM sleep to lighter REM sleep. During an episode, a child may:

• Sit up suddenly in bed

• Scream or shout in distress

• Breathe rapidly or have an increased heart rate

• Sweat or thrash around

• Appear fearful or upset

Children experiencing night terrors may seem completely unresponsive to attempts to soothe them. This can be alarming for parents, but it is usually not a sign of an underlying medical problem. Night terrors are often triggered by:

• Being overtired or not getting enough sleep

• Stress or anxiety

• Illness

• Sleeping in a new or unfamiliar environment

• Consuming caffeine or sugar late in the day

  
  

Safety Measures During Night Terrors

Children with ASD may have difficulty calming down during night terrors and can be at risk of injury. Parents can take the following steps to ensure safety:

• Cushion sharp corners on furniture or the bed

• Remove obstacles from the bedroom floor

• Use extra security on doors if sleepwalking is possible

• Make sure the child’s sleeping environment is clear of hazards

It’s important to stay calm and avoid physically restraining the child, as they are often confused and disoriented during an episode.

Improving Sleep Hygiene

Better sleep routines can reduce the frequency and intensity of night terrors. Parents can help by:

• Establishing a consistent bedtime and wake-up schedule

• Avoiding caffeine or sugary drinks before bedtime

• Creating a relaxing, stress-free sleeping environment

• Minimizing noise and bright lights in the bedroom

• Ensuring a comfortable room temperature

Behavioural Strategies

For children over six who experience frequent night terrors, it may help to:

• Track the timing of night terrors to predict when they occur

• Gently wake the child 15 minutes before the expected onset and keep them awake for 5 minutes

• Repeat this process until the episodes become less frequent or stop

Teaching children emotion regulation skills can also be beneficial. This helps them manage fear and distress during sleep disturbances and reduces overall anxiety.

Key Takeaways

• Night terrors are a common sleep challenge for young children, including those with ASD.

• They are generally not dangerous and often decrease as the child matures.

• Ensuring safety, improving sleep hygiene, and using behavioral strategies can make night terrors less frequent and less distressing.

• Parents should remain calm, support emotional regulation, and seek help if night terrors are severe or persistent.

  
  

By creating a safe and structured sleep environment, parents can help their children get better rest and minimize the impact of night terrors on their daily behaviour and wellbeing.
