The Science Behind Sleep Difficulties in Autism

The Science Behind Sleep Difficulties in Autism — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A research-grounded visual explaining why sleep struggles in autism aren't about bad habits or poor routines — differences in melatonin, nervous system arousal, and sensory load genuinely make falling and staying asleep harder.

This infographic covers:

• Four contributing factors: melatonin/circadian timing, nervous system arousal, sensory load, and body discomfort/interoception
• How the cycle unfolds: night-time cues → brain/body stay alert → falling asleep takes longer → sleep is lighter or interrupted → daytime tiredness and regulation are harder
• Why sleep can be hard: melatonin timing differences, high arousal, sensory load, body signals
• What it can look like: taking a long time to fall asleep, frequent waking, restless movement, seeming exhausted but unable to switch off, bedtime distress
• What research points to: melatonin differences, sensory sensitivities, hyperarousal and regulation difficulties
• What actually helps: reduce sensory load, support regulation first, use predictable sleep cues, watch for body discomfort, give the brain time to slow, seek medical support when needed

What you get:

• High-resolution PDF, print-ready and scalable up to A2 (420 × 594mm)
