Comparing the Effectiveness of Physical Exercise Intervention and Melatonin Supplement in Improving Sleep Quality in Children with ASD.
Exercise and melatonin are equally good at helping kids with autism sleep—let the family’s lifestyle pick the tool.
01Research in Context
What this study did
Kids with autism often lie awake for hours. The researchers asked: could bedtime cycling or a melatonin pill fix this?
They randomly gave one group cycling, one group melatonin, one group both, and one group placebo for several weeks. Then they tracked sleep quality.
What they found
All three active plans beat the placebo. Kids fell asleep faster and woke up less.
Surprise: exercise worked just as well as the hormone pill. The combo was no better than either single plan.
How this fits with other research
Reid et al. (2003) already showed tiny 0.3 mg melatonin doses help people with intellectual disability sleep. The new trial moves that idea into autism and keeps the benefit.
Wang et al. (2024) found that three 60-minute activity sessions per week shortened sleep latency in kids with ADHD. Zhang et al. (2024) now show the same gain in autism, so the exercise effect crosses diagnoses.
Tanksale et al. (2021) blended yoga with CBT and also saw parent-rated sleep gains. Together these studies widen the menu: aerobic, mind-body, or pill all move the sleep needle.
Why it matters
You no longer need to choose between ‘natural’ and ‘medical.’ If parents fear pills, prescribe evening bike rides. If schedules are packed, a low-dose melatonin gummy works just as fast. Document baseline sleep latency, pick one option the family will actually do, and reassess in two weeks.

03Original abstract
PURPOSE: Previous studies have demonstrated that physical exercise can modulate the endogenous melatonin level in children with autism spectrum disorder (ASD) and improve their sleep quality. However, it remains unclear whether physical exercise or melatonin supplement, or a combination of both, is more effective in improving sleep quality in this population. The purpose of this study is to answer this research question by comparing the effectiveness of three types of interventions (physical exercise vs. melatonin supplement or a combination of both) in improving sleep quality in children with ASD. METHODS: Sixty-two (62) children diagnosed with ASD were randomly assigned to one of four groups: cycling (n = 18), melatonin supplement (n = 14), a combination of both (n = 12), and placebo control group (n = 18). Four (4) sleep parameters (sleep efficiency, sleep onset latency, sleep duration, and wake after sleep onset) were assessed. RESULTS: The results revealed a significant improvement in sleep efficiency, sleep onset latency, and sleep duration in all of the interventions, but not in the placebo control group. However, no significant group differences were found among the interventions (ps > .05). CONCLUSION: Our findings suggest similar effectiveness of physical exercise and melatonin supplementation in improving sleep quality in children with ASD.
