ADHD and sleep: breaking the vicious cycle

The loop

An ADHD brain finds it hard to switch off, so bedtime is late. Late bedtime means short sleep. Short sleep makes attention, mood and impulse control worse the next day, which looks like more ADHD, which makes the next bedtime harder. Round it goes. Sleep is not a side issue in ADHD. It is often the amplifier.

Why switching off is hard

Three things stack up. The body clock in ADHD tends to run late, so the child is genuinely not tired at the time the rest of the house is. The mind, quiet at last, starts to run: the day's worries and ideas arrive the moment the stimulation stops. And some ADHD medications, particularly stimulants, can push sleep later if the timing is wrong.

What actually helps

The same wake time every day, including weekends, anchors the clock better than anything else. Bright light in the morning and dim, warm light after tea nudges a late clock earlier over weeks. A wind-down that is a routine, not a description: the same sequence, in the same order, every night, so the body learns what comes next. Movement in the day, because a body that has not moved does not want to stop. A worry drop: worries written down and parked before lights out.

When to ask

If sleep problems have lasted weeks and are affecting the day, keep a two-week sleep diary and take it to your GP. If your child is on ADHD medication, the prescriber can adjust timing or type. Melatonin is sometimes used for children with ADHD, always on specialist advice. Sleep is one of the few levers that improves everything else at once, so it is worth pulling properly.
