It's midnight. Everyone else in the house is asleep. You're lying in the dark, completely exhausted — and completely awake. Your brain is reviewing a conversation from last Tuesday. Planning tomorrow's tasks. Wondering whether you said something weird to that person three weeks ago. Solving a problem that doesn't actually need solving at midnight.
ADHD sleep problems are one of the most common — and least discussed — symptoms of ADHD in adult women. And the standard sleep hygiene advice almost never addresses what's actually happening.
"I was exhausted every single day for years. I thought I just wasn't a good sleeper. It turned out my brain was doing something very specific at night, and nobody had ever explained what or why."
Why ADHD brains specifically struggle with sleep
Several factors combine to make sleep genuinely harder with ADHD — not just harder to prioritise, but neurologically harder to achieve.
Circadian rhythm differences. Research shows that many people with ADHD have a naturally delayed circadian rhythm — their internal clock runs later than average. Feeling wired at midnight and impossible to wake at 7am isn't poor discipline; it's often a genuine biological difference.
Dopamine and the evening paradox. During the day, the ADHD brain is often understimulated. In the evening, when the pressure and demands of the day ease, some people experience a burst of dopamine-seeking activity — suddenly productive, suddenly engaged, suddenly reluctant to stop. This is the ADHD "second wind," and it directly conflicts with falling asleep at a reasonable hour.
Racing thoughts and hyperarousal. The same brain that struggles to focus during the day can become intensely active in the quiet of the night. Without external stimulation to anchor it, the ADHD brain generates its own — through thought loops, planning, worry, and replay.
Emotional processing. RSD (rejection sensitive dysphoria) and emotional dysregulation don't stop at bedtime. Unresolved emotional content from the day is often processed at night, when there's finally quiet — which makes falling asleep after a difficult day particularly hard.
What actually helps — ADHD-specific sleep strategies
What doesn't work — and why
Strict bedtime routines without flexibility. The most common sleep hygiene advice is "go to bed at the same time every night." For ADHD brains with delayed circadian rhythms and variable dopamine levels, rigid bedtimes often produce anxiety and lying awake, not sleep. Consistency in wake time is more achievable and more useful.
No screens after 9pm (if that's when your brain finally engages). Blanket screen bans ignore the evening second wind phenomenon. A better approach: use screen-dimming tools, choose passive or low-stimulation content in the evening, and accept that some evening screen use may be unavoidable for now.
Expecting sleep problems to resolve with "relaxation." The ADHD sleep problem is neurological. Relaxation techniques help the average stressed person fall asleep faster — but they don't address circadian rhythm differences, dopamine-driven hyperarousal, or racing thoughts. These need ADHD-specific strategies, not generic wind-down advice.
"Sleep difficulties are not a personal failure. For the ADHD brain, falling asleep requires a different approach — and the good news is that there are approaches that actually work."
