You’re lying in bed. It’s 1:47 AM. You have an early meeting. And you are tossing and turning telling yourself (in your head) “You KNOW you need to sleep!”
And your brain just… won’t stop.
It replays that tense meeting you had at work. It reminds you about the email you forgot to send. And you are worrying about tomorrow’s presentation. And the harder you try to relax, the more awake you feel.
Does this feel familiar?
If it does, I want you to know something. Your brain is actually doing exactly what it’s designed to do.
Here’s the thing: stress itself isn’t the enemy. We actually NEED stress. It’s what drives us to prepare for a big presentation, meet a deadline, push through a hard workout. Think of it like strength training. When you lift weights, you’re deliberately stressing your muscles. That stress is what makes them grow stronger. Without it, nothing changes.
The problem isn’t that stress exists in your life. The problem is when the stress becomes so constant or so intense that your body loses the ability to shift back into a relaxed state when the stressor isn’t actually present. When you’re lying in bed at 1 AM and there’s nothing to solve right now, but your brain keeps looping through the same worries anyway. Not generating new ideas or solutions, just cycling through the same anxious thoughts on repeat. That’s not productive stress. That’s a nervous system that’s stuck. Even if the stress is helping you generate new ideas and explore solutions… that’s not what you want in the middle of the night, night after night.
And then there’s the kind of stress that is simply too much. A toxic work environment. An abusive relationship. If you’re in one of those situations, I’d encourage you to get support, start working on a safe exit strategy, or both. That’s a whole other topic for another day, but it matters and I didn’t want to skip past it.
For the rest of this post, I’m talking to the person whose life isn’t in crisis, but whose body has forgotten how to rest. You’re dedicated, you care deeply about your work, and you’re carrying more than you probably realize. And your sleep is paying the price.
Why Stress Wrecks Your Sleep
When you’re under stress, your nervous system stays in a state of high alert. Your body keeps producing cortisol (the stress hormone) even after the workday is over. And cortisol suppresses melatonin, the hormone that helps you fall and stay asleep.
Here’s what’s really happening: your brain is treating your work stress like a survival threat. It doesn’t know the difference between a tiger and a difficult conversation with a colleague. And so it keeps you alert. Watchful. Ready to react.
That’s the nervous system in action.
The problem is that this creates a vicious cycle. Poor sleep makes your brain MORE reactive to stress the next day. More cortisol at night. Worse sleep. And on it goes.
And it’s not just about feeling tired. When you don’t sleep well, your body cannot recover from the day’s stress. Your memory suffers. Your emotional regulation suffers. Your immune system suffers. The very things you need to show up fully at work and at home are the first things to go.
Why “I Got Seven Hours” Doesn’t Mean Much
First, let’s talk about how much sleep you actually need. Sleep researchers, including Dr. Matthew Walker (author of Why We Sleep), recommend giving yourself a minimum eight-hour sleep opportunity every night. That means eight hours in bed, not eight hours of sleep. It can take up to 20 minutes to relax into good quality sleep, and you usually wake up somewhat gradually in the morning. So in reality, an eight-hour window gives you about 7 to 7.5 hours of actual sleep. That’s the minimum your brain needs to complete all its repair and restoration cycles.
But here’s the catch: stress fragments your sleep. It pulls you out of deep, restorative stages. So if you’re under chronic stress, you may need a wider sleep opportunity — nine or even ten hours — just to get the same recovery your brain would normally get in eight.
We know this is true for physical stress. Athletes under high training loads are encouraged to get 9-10 hours of sleep because the body needs more deep sleep to repair itself. Whether the same applies to chronic cognitive and emotional stress hasn’t been studied as thoroughly, but the underlying biology is similar: stress creates wear and tear, and sleep is when your body does its repair work. More wear and tear likely means more repair time needed.
Most people measure sleep by hours. But hours alone don’t tell you much.
What matters is what happens DURING those hours. Your brain cycles through different stages, and each one does something different:
Deep sleep is when your body physically repairs itself, your brain clears out metabolic waste, and your memories get consolidated. This is the stage that makes you feel rested. It’s also the stage that can help prevent cognitive decline.
REM sleep is when your brain processes the emotions from your day. If you’ve ever woken up feeling calmer about something that stressed you out the night before, that’s REM doing its job.
When stress disrupts your sleep, it hits deep sleep and REM. You might clock seven hours in bed but spend most of it in light sleep. That’s why you wake up feeling like you barely slept at all.
Some signs your sleep quality is suffering:
- You wake up tired even after a “full night”
- You wake up multiple times during the night
- It takes you more than 20 or 30 minutes to fall asleep
- You feel foggy or irritable by mid-afternoon
- You depend on caffeine just to function in the morning
If three or more of these sound familiar, it’s probably not about needing more sleep. It’s about needing BETTER sleep.
Three Things That Actually Help
Your sleep environment and habits
The basics matter more than most people think. A consistent bedtime. Less screen time before bed. A dark, cool room. Cutting caffeine earlier in the day (it has a half-life of about 6 hours, so that 3 PM coffee is still in your system at 9 PM).
None of these are revolutionary on their own. But together, they signal to your nervous system that it’s safe to wind down. I put together a free checklist with the most important sleep habits according to sleep researchers. You can download the checklist here.
Your diet and your hormones
Alcohol is a big one. It might help you fall asleep faster, but it seriously disrupts REM sleep (the part where your brain processes emotions). So you might be sleeping, but you’re skipping the stage your stressed brain needs the most.
And for women in their 40s and 50s, shifting hormone levels can completely change your sleep patterns. If your sleep suddenly got worse and nothing else in your life changed, that’s worth a conversation with your doctor. You can also explore Dr Mendi’s menopause protocol or chat with me about dietary interventions that support women going through menopause.
Training your brain to regulate itself
Sleep hygiene and diet create the right conditions. But if your nervous system has been stuck in high alert for months or years, sometimes it needs more direct help learning to shift gears.
This is where neurofeedback brain training comes in. It helps your brain practice the patterns associated with calm, focused states, including the ones it needs for deep, restorative sleep. No medication. Not talk therapy. It’s your brain learning to do what it already knows how to do, but has forgotten under the weight of chronic stress.
I’ve seen people who haven’t slept well in years start noticing a difference within the first few weeks of training. Not because they’re forcing themselves to relax, but because their brain is actually regulating itself differently.
Where to Start
Pick one thing. Download the sleep checklist and try one new habit this week. Notice how your sleep responds when you give your body even a small signal that it’s OK to rest.
