Sleep and Autism
Studies estimate that 50–80% of autistic children have significant sleep difficulties, compared to roughly 25% of neurotypical peers. The most common patterns are trouble falling asleep, frequent night waking, and early-morning waking.
Why sleep is harder
- Melatonin differences — many autistic people produce less melatonin, or produce it on a shifted schedule.
- Sensory sensitivity — light, sound, tags, temperature.
- Anxiety and rumination — a busy brain at bedtime.
- Co-occurring conditions — ADHD, GI issues, epilepsy.
The Autism Speaks ATN sleep steps
The Autism Treatment Network's parent sleep toolkit is the most widely recommended starting point. In order:
- Fix the environment first. Dark, cool (65–68°F / 18–20°C), quiet or consistent white noise. Remove screens from the bedroom.
- Consistent schedule. Same bedtime and wake time within 30 minutes, every day, weekends included.
- Wind-down routine. 20–30 minutes, same steps in the same order, ending in the sleep space.
- Address daytime factors. Caffeine (including chocolate) out by early afternoon; get outdoor light in the morning; cap naps for kids over 5.
- Behavioral strategies. Graduated extinction, bedtime fading, and scheduled awakenings all have research support.
- Talk to a clinician about melatonin. Small doses (0.5–3 mg) 30–60 min before bed have the strongest evidence, but should be a doctor conversation — not a Costco decision.
When to escalate
Loud snoring, gasping, or pauses in breathing → sleep study for obstructive sleep apnea. Restless legs, night sweats, sudden regression → medical work-up.
