0:00Night and following day
Sleep is so important in adult ADHD that I want it near the centre of the conversation. A person who is constantly tired is doing the day's work with an additional load. They may still be energetic, talkative or restless, but that does not tell us whether their sleep is adequate. I want to understand the whole night and the day that follows it: when sleep begins, what interrupts it, when waking happens and what the person feels like afterwards.
0:28Protect the whole night
Both non-REM and REM sleep matter. They occur in repeated cycles, with deep non-REM sleep generally more prominent earlier in the sleep period and REM periods lengthening later. Protecting a whole night gives those cycles room. Sleep participates in learning, memory and bodily regulation; it is an active process, even though we are resting. I want us to take that activity seriously and recognise how easily modern routines consume the time it requires.
1:00Conditions for sleep
When I say sleep hygiene is paramount, I mean that we must examine the conditions in which sleep is being attempted. Bright evening light, screens within reach and content without an ending can all belong to a late-night pattern. Reducing light and getting away from screens gives the evening a clearer transition. It also removes the next reel, episode or message that keeps offering a reason to remain awake. A winding-down routine needs an actual place in the day; leaving it until every other demand is finished often leaves no time for it.
1:36Bedtime building blocks
Bedtime itself contains executive demands. You have to notice the time, stop an activity, accept unfinished work, prepare for tomorrow and change state. Someone may know perfectly well that they should go to bed and still struggle with this sequence. We can make its building blocks visible: a last point for work, a place for the phone, what needs preparing and the first action that begins winding down. An occupational therapist can work through that sequence with the person rather than leaving “sleep earlier” as a large, vague instruction.
2:12What evening provides
We also need to ask what late evening means to someone. It may be the only quiet time after work, care and social demands. Giving it up can feel like losing the only part of the day that belongs to you. In that situation, a bedtime plan needs some attention to daytime boundaries and recovery. There may also be a later internal sleep rhythm. A recent study using activity-monitoring devices found later and less stable rest and activity patterns in newly diagnosed adults with ADHD. Understanding a person's timing gives us a better starting point than repeatedly asking them to lie awake earlier.
2:51Sleepiness and assessment
Sleepiness and ADHD symptoms need careful attention together. Adult studies show that losing sleep worsens attention, and that visible daytime sleepiness is associated with more missed responses. I ask people to notice whether a difficult morning follows a short night, repeated waking, a late sleep period or an adequate night that still leaves them unrefreshed. Persistent insomnia, gasping, loud snoring, restless legs and marked daytime sleepiness deserve clinical assessment. A routine can be carefully designed and still need a sleep disorder addressed. For persistent insomnia, structured treatment such as cognitive behavioural therapy for insomnia has stronger evidence than sleep hygiene alone.
3:39Medication and sleep
Medication belongs in this account as well. Review what happens to sleep as treatment, dose or timing changes. A recent observational adult clinic study, conducted over eighteen months, found better reported sleep outcomes associated with ADHD medication use. The person's own pattern matters: treatment may help them organise an evening, while a particular prescription or timing may also require adjustment. Working on sleep alongside medication review allows both parts of care to respond to the actual difficulty.
4:13One night-protecting change
For a practical beginning, choose one change that protects the night: an earlier ending to content, less bright light, a realistic waking time or help with the evening transition. Observe sleep and the following day, then review. If sleep remains difficult, deepen the assessment. A recent trial of added sleep treatment found improvements in sleep quality and fatigue, without a clear additional improvement in ADHD symptoms. Those sleep and fatigue outcomes matter in their own right. I want people to have enough rest to live their day, and enough support to make that rest possible.
