In this episode of The Diary of a CEO, featuring Steven Bartlett and Dr. Michael Breus, Human Sleep Expert: Don't Pee In The Middle Of The Night & Why Night Time Sex Isn't A Good Idea! explores practical sleep science: chronotypes, mid-night waking, apnea, and better routines Sleep specialist and psychologist Dr. Michael Breus breaks down how sleep works (sleep drive vs. circadian rhythm) and why aligning daily behaviors with your chronotype can improve energy, productivity, and even relationship timing.
Practical sleep science: chronotypes, mid-night waking, apnea, and better routines
Sleep specialist and psychologist Dr. Michael Breus breaks down how sleep works (sleep drive vs. circadian rhythm) and why aligning daily behaviors with your chronotype can improve energy, productivity, and even relationship timing.
He gives actionable protocols for common issues—especially waking between 1–3 a.m.—and emphasizes heart rate, temperature, and anxiety management as key levers.
The conversation highlights underdiagnosed sleep apnea (including sex-based symptom differences), its health risks (including Alzheimer’s links), and modern home testing/treatment options.
Breus also critiques widespread melatonin use (especially in children), discusses evidence-backed supplements and deficiency testing, and shares concrete bedroom environment and pillow-fitting guidance.
Key Takeaways
Treat sleep as two systems: drive and rhythm.
Breus frames sleep as a combination of adenosine-driven sleepiness (sleep drive) and circadian timing (sleep rhythm). ...

Use a “nap-a-latte” for a targeted energy reset.
Drink black coffee quickly, then nap ~25 minutes so adenosine clears while caffeine is still absorbing; caffeine then blocks new adenosine binding. ...

Delay morning caffeine ~90 minutes and hydrate first.
He recommends 15–20 oz (roughly 3–4 cups) of water on waking and avoiding caffeine for the first 90 minutes. ...

Morning sex often beats nighttime sex hormonally.
Breus argues late-night sex is mismatched with typical hormone profiles (melatonin high; sex-supportive hormones lower). ...

If you wake between 1–3 a.m., don’t automatically pee or check the time.
He attributes this window partly to normal core temperature cycling and says most people return to sleep quickly unless they spike arousal. ...

Lower heart rate to re-enter sleep: 4-7-8 breathing + distraction.
His go-to protocol is 4-7-8 breathing for ~20 cycles (or scaled-down counts), using finger counting to track cycles. ...

Sleep apnea is common, dangerous, and massively underdiagnosed.
The episode cites ~1 in 7 adults with obstructive sleep apnea and 80–90% undiagnosed. ...

Women’s sleep apnea can look different—so screening needs to adapt.
Breus notes women may report less snoring and more awakenings/arousals and morning headaches, leading to mislabeling as insomnia. ...

Anchor your week with a consistent wake-up time, not just bedtime.
For insomnia and general sleep stability, he prioritizes waking at the same time 7 days/week. ...

Melatonin is overused; dose low, avoid kids, and watch interactions.
He stresses melatonin is a hormone (prescription-only in many countries), a sleep-timing regulator (not a sedative), and can interact with SSRIs, birth control, blood pressure meds, and diabetes meds. ...

What are the most popular questions people come to you with as a sleep doctor?
There's three biggies. Number one is, what do I do if I fall asleep okay, and I wake up in the middle of the night, and I can't fall back asleep?
And you can help people with that?
Absolutely. The second question is, what pillow should I buy? And I'm gonna walk you through which pillows make sense for which people. And then another one that people ask me all the time is, what's the best time to have sex?
That's a strange thing for somebody of your profession to be-
Yeah
-thinking much about.
Well, let me explain why. So I've been an actively practicing sleep specialist for twenty-six years, and I take care of people's sleep problems like apnea, insomnia, and I'm really interested in the things that you might be doing right now that are messing up your sleep, that are easy to fix. So, for example, most people don't know that they have a genetic sleep code inside them, called their chronotype, which decides when your brain releases things like melatonin, cortisol, adrenaline, and dopamine. And so I can show you, based on your chronotype, when it's bedtime, but also the perfect time of day to do almost any activity, including the perfect time to have coffee and alcohol.
Crazy.
There's even data to show that your ability to understand complicated concepts improves when you're more in line with your chronotype. Now, there are three known chronotypes, but what I'm famous for is discovering a fourth one, which I think might be you. So we're gonna talk a lot about that. We're also gonna talk about dreams, because dreams can tell you things about yourself that you may not wanna know. And then there's how to fix jet lag, whether you should sleep with a TV on, the truth about melatonin supplementation, and my favorite way to get magnesium.
But before we get into all of that, shall we go and look at the best possible sleep position?
Yeah, let's check it out.
Guys, I've got a quick favor to ask you. We're approaching a significant subscriber milestone on this show, and roughly sixty-nine percent of you that listen and love this show haven't yet subscribed for whatever reason. If there was ever a time for you to do us a favor, if we've ever done anything for you, given you value in any way, it is simply hitting that subscribe button, and it means so much to myself, but also to my team. 'Cause when we hit these milestones, we go away as a team and celebrate. And it's the thing, the simple, free, easy thing you can do to help make this show a little bit better every single week. So that's a favor I would ask you, and, um, if you do hit the subscribe button, I won't let you down, and we'll continue to find small ways to make this whole production better. Thank you so much for being part of this journey. It means the world and, uh, yeah, let's do this. [upbeat music] Dr. Breus.
