A Coffee Conversation
Companion to: “ADHD and Sleep”
The participants:
Jennifer and Mark — parents of Ethan, 16, diagnosed with ADHD at age 9
Dr. Nina Brandt — researcher, circadian biology and ADHD, University of Utrecht
Dr. Rachel Torres — licensed psychologist, positive psychology orientation
Dr. Douglas Cowan — licensed marriage and family therapist, 39 years clinical practice
They’ve gathered to talk through a new clinical paper on ADHD and sleep — what it found, what it means, and what families can actually do with it.
Jennifer: I have to say — I read the summary of this article and I actually cried a little. Not sad crying. The other kind. We have had the 10 PM homework fight for three years. Three years of me standing in the doorway saying “Ethan, why didn’t you start this at 6?” And him not being able to explain it. And me not being able to understand it.
Mark: We thought he was avoiding it. I mean — what else would you think? He’s on his phone all afternoon and then suddenly at 10:30 he’s writing an essay.
Dr. Brandt: This is exactly what our data shows, and it’s what makes this pattern so difficult for families. From the outside, it looks like avoidance or procrastination. But when we measure circadian timing in adolescents with ADHD, we consistently find that the signal telling the brain “it’s time to engage, time to be alert, time to do complex cognitive work” arrives significantly later than it does in their neurotypical peers. Sometimes two hours later. For Ethan, 10 PM may genuinely be when his brain reaches its functional peak.
Jennifer: So when I was angry at him at 7 PM for not focusing — his brain wasn’t even ready yet.
Dr. Brandt: In many cases, no. Not because of anything he chose. The dopaminergic system that regulates both ADHD and circadian timing is operating on a delayed schedule. He’s not behind the schedule you can see on the clock. He’s on a different schedule entirely.
Mark: That’s — I don’t know whether to feel relieved or terrible about the last three years.
Dr. Cowan: Both of those things can be true at the same time. That’s actually a healthy response. The fact that you’re sitting here wanting to understand it rather than just punish it — that matters more than you know.
Dr. Torres: Can I add something here? Because this is where I think the Seligman framework becomes really important. Martin Seligman spent decades studying what he called learned helplessness — the point where a person stops trying because nothing they do seems to make a difference. I see that pattern in a lot of ADHD families. Ethan has probably tried to start homework at 6. He’s sat there. Nothing came. He tried again. Nothing. Eventually the brain learns: “Homework at 6 doesn’t work. I don’t work at 6.” And it’s not wrong. But the family interprets that as giving up.
Jennifer: He has given up on trying earlier. He just doesn’t even attempt it now until late.
Dr. Torres: Right. And that looks like defiance. But it might actually be information. His nervous system learned something true — that 6 PM is not his window — and it stopped fighting that truth. The problem is nobody named what was happening, so instead of a strategy, it became a character flaw.
Dr. Cowan: And that’s where the research becomes pastoral work. The science gives us language. Language lets families stop fighting each other and start working on the actual problem.
Mark: So what do we do? Because he still has to be up at 7 for school. That hasn’t changed.
Dr. Brandt: The goal is to gradually shift the clock earlier — not dramatically, and not overnight. The most evidence-based approach is morning light exposure. Within thirty minutes of waking, bright outdoor light or a 10,000-lux lamp. Consistently. Including weekends. The brain anchors its circadian schedule to wake time, so a consistent wake time — even on Saturday — slowly pulls the clock forward.
Dr. Torres: And I’d add: don’t fight the 10 PM window while you’re working to shift it. Work with it strategically. If that’s when Ethan’s brain shows up, create a structured session — 9:30 to 11:00, with a hard stop. Clear environment, no phone, visual timer. You’re not endorsing the late schedule permanently. You’re honoring where the brain is while you move it in the right direction.
Jennifer: A hard stop at 11. Even if he’s not done.
Dr. Cowan: Especially if he’s not done. Because the cost of staying up until 1 AM is paid the next day — and the day after. Sleep deprivation doesn’t just make Ethan tired. It specifically hits the same functions ADHD already makes hard. Working memory, emotional regulation, the ability to start things. He shows up to school the next morning running at a deficit on top of a deficit.
Mark: I didn’t know that. I thought the exhaustion was just — tiredness.
Dr. Brandt: It’s more specific than that. Chronic sleep restriction in ADHD populations amplifies the core symptom profile. A teenager with ADHD running on five hours is not functioning with ADHD plus fatigue. They are functioning at a significantly more impaired level than either condition alone would predict.
Dr. Torres: And here’s where I want to come back to Seligman — because Learned Optimism makes a distinction that I think matters for Ethan. There’s a difference between a permanent problem and a temporary condition that can be shifted. Ethan’s clock runs late. That is true right now. It is not true forever. The research shows these patterns respond to consistent chronobiological intervention. Morning light. Melatonin taken early — small doses, 0.5 to 1 milligram, sixty to ninety minutes before the target sleep time, not the big gummy-bear doses. Consistent wake time. Over weeks, the clock moves.
Jennifer: Weeks.
Dr. Torres: Weeks. Not mornings.
Dr. Cowan: This is where I want to say something to both of you directly. Ethan is not failing. He found the one window his brain gives him, and he used it to get his work done. That’s not a kid who doesn’t care about school. That’s a kid who figured out how to survive a system that isn’t built for his nervous system. The goal now is to give him better tools — not because what he’s been doing is wrong, but because he deserves to be less exhausted.
Mark: When you put it that way, it sounds different.
Dr. Cowan: It is different. That’s the point.
Jennifer: What about talking to the school? His first period teacher — Ethan is a disaster in that class. She thinks he’s not interested in the subject.
Dr. Brandt: There is growing support in the literature for chronobiological accommodations — later testing times, flexibility in first-period expectations, documentation of delayed sleep phase as a component of the ADHD presentation. A neuropsychological or medical report framing the sleep pattern neurobiologically opens more doors than a behavioral explanation does.
Dr. Torres: And it changes the story the school tells about Ethan. Right now the story might be “unmotivated in the morning.” The accurate story is “neurobiologically impaired in the first two hours after waking due to a shifted circadian rhythm associated with ADHD.” Those are very different stories.
Mark: He’s not unmotivated. He’s still sleeping, neurologically, when the bell rings.
Dr. Torres: Exactly.
Dr. Cowan: That’s a good place to land. Because when you go home tonight, I want you to carry two things. One is practical — start the morning light this week. Consistent wake time, including Saturday. Those two things alone begin to move the clock. The second thing is the story. The story about Ethan changed in this room today. He’s not defiant. He’s not lazy. He’s a kid with a shifted biological clock doing his best inside a schedule that wasn’t designed for him.
And a kid who can write a full essay at 10:30 PM when his brain finally comes online — that’s a kid with plenty in him. The work now is building the conditions that let him access it at better times.
That’s worth doing. And it’s possible.
