147: Kathryn Nicolai: Why Women Who Train the Hardest Are Often the Ones Who Sleep the Worst
Why the Women Who Train the Hardest Often Sleep the Worst
Let's start with something that might sting a little: rest is not a reward. It's not something you earn after a hard enough day or a clean enough week of workouts. Your body needs rest the same way it needs water. No negotiation, no extra credit for skipping it. And yet so many women are running on fumes and calling it discipline.
Here's the part that really stands out. The women who push the hardest, who never miss a workout, who are first up and last to sit down, are so often the same women lying wide awake at midnight, completely wired, wondering why their body will not shut off. It's easy to assume that exhausting yourself during the day should knock you out at night. But pushing through everything, all day, every day, does something to your nervous system that a few hours in bed can't undo on its own. Nobody really talks about that part. So this episode does.
This week's conversation is with Kathryn Nicolai, the creator of Nothing Much Happens, the biggest sleep podcast in the world with over 200 million downloads. Before that, she spent two decades as a yoga and meditation teacher, working with real women through real, messy seasons of life. Everything she's built since is rooted in that experience: a science-backed approach to rest, nervous system regulation, and how the way you move through your day either quietly supports your sleep, or quietly wrecks it.
If you train hard and still stare at the ceiling most nights, this one's for you.
Why Pushing Through Catches Up With You at Night
The women who handle the most, who keep going no matter what, are often carrying the heaviest nervous system load without even realizing it. Every time you power through stress instead of processing it, your body files that stress away rather than releasing it. It doesn't just disappear because your to-do list got shorter. It sits there, waiting. And it tends to show up right when you finally lie down and ask your brain to power off.
This is one of those reframes that changes how you see your whole day, not just your nights. If you've ever wondered why you can be bone-tired and still feel completely unable to fall asleep, this is why. Tired and wired can absolutely coexist, and training intensity has very little to do with fixing that on its own.
What a Stress Cycle Actually Is, and Why You Probably Have Too Many Open
Kathryn brings up this idea of "open tabs." Think about how your laptop slows to a crawl when you've got forty tabs running in the background. Your nervous system works the same way. Every unresolved stressor, every unfinished conversation, every moment you white-knuckled through instead of processing, stays open. A stress cycle is your body's way of completing that loop, signaling to itself that the threat has passed and it's safe to power down.
The problem is most people never close the tab. They move from one stressor straight into the next without ever giving their body the signal that it's safe to rest. So even when you're physically still, your nervous system is still running the program. Closing that cycle isn't about willpower. It's about giving your body specific signals it recognizes as "we're safe now," which is a completely different skill than trying to relax harder.
What Most People Get Wrong About Why They Can't Sleep
Most of us treat sleep like a willpower problem. Dim the lights, put the phone away, maybe a melatonin gummy, and if it still doesn't work, assume something's broken. But sleep struggles are rarely a discipline issue. They're a regulation issue. Your nervous system has to believe it's safe before it will let you drop into real rest, and no sleep hygiene checklist can override a body that's still bracing for the next thing.
This is exactly why "just try to relax" never works when you're wired. You can't think your way into a calm nervous system. You have to give it evidence.
Why Storytelling Works When Meditation and White Noise Don't
This part of the conversation is genuinely fascinating. There's a reason a podcast built entirely around gentle stories has helped millions of people fall asleep where meditation apps and white noise didn't land the same way. A story gives the brain something specific and low-stakes to follow. It occupies the part of the mind that wants to keep working, keep planning, keep scanning for problems, without asking anything of it. Meditation can actually backfire for an overactive brain because it asks you to sit with stillness, and stillness is exactly what a wired nervous system doesn't trust yet. A story meets the brain where it actually is instead of where it's supposed to be.
Brain Training Is Real, and Consistency Is What Makes It Work
None of this is a one-night fix, and that's actually the most freeing part of the conversation. The brain can be trained to associate certain cues with safety and rest, the same way it's been trained, often without permission, to associate other cues with stress and vigilance. The more consistently you give your nervous system those rest signals, night after night, the faster it learns to actually let go. This is no different from training the body in the gym. Reps matter, and consistency rewires the pattern.
What To Do When Nothing Is Working
Even with all of this, there are nights when nothing seems to land. For those nights, having a small, low-pressure plan matters more than having the perfect one. Something simple to return to without overthinking it is far more useful at 2am than a brand-new strategy never tried before. The goal isn't to force sleep. It's to keep giving the body small, repeated signals that it's safe, until it finally believes you.
The Real Talk
If there's one thing to take from this episode, it's this: you cannot out-train a dysregulated nervous system, and you cannot earn your way into rest through sheer effort. The harder you push without ever closing the loop, the more your body will fight you at night. Rest isn't the opposite of hard work. It's what makes hard work sustainable.
If your training is dialed in but sleep still feels like a losing battle, it might be less about the bedtime routine and more about how you're moving through stress all day. Start paying attention to where you're white-knuckling instead of processing, and give your body small, consistent signals that it's allowed to stand down.
While you're working on closing those stress cycles, make sure the rest of your foundation is just as solid. The Macronutrient Guide is a simple place to start fueling the body you're building, and if you're ready for real structure and support around training and recovery, BroadsCOACH is exactly where that happens.
So here's the question worth sitting with: when you think about your own nights, is it really the bedtime routine that's the problem, or is it everything you never quite let go of from the day before?
