Why You Keep Waking Up at 3 A.M. (And How to Actually Fix It)

Hey mama, if you’re waking up at 3 A.M. and staring at the ceiling like, “What fresh hell is this?” — you’re not alone. It’s not just bad luck; it’s biology. Specifically, your stress hormone cortisol is probably throwing a tantrum when you need it least.

Let’s break it down, no fluff, just facts.

What’s Really Happening at 3 A.M.?

Cortisol is your body’s internal alarm clock. It peaks about 2–3 hours after you fall asleep, hitting its highest point around the 9-hour mark. That’s when it’s supposed to help you wake up feeling refreshed. Better Report

But if you’ve been running on fumes all day — juggling work, kids, life — your cortisol levels are already elevated before you even hit the pillow. So, instead of a smooth wake-up, your body starts pumping out more cortisol around 3 A.M., thinking it’s time to rise and shine. Spoiler: It’s not.

Another sneaky culprit behind those 3 A.M. wake-ups? Blood sugar swings. When your glucose drops too low overnight, your body senses it as a mini “crisis” and spikes cortisol to wake you up and mobilize energy. Research shows that even small dips in blood sugar can trigger this stress response, especially in moms juggling erratic schedules and late-night feedings.

Why This Is a Big Deal

Elevated cortisol at night messes with your sleep cycle. It can:

• Prevent deep sleep: You’re stuck in light sleep, not getting the restorative rest you need.

• Disrupt REM sleep: That’s the sleep that helps with memory, mood, and brain function.

• Increase stress: More cortisol means more stress, which makes it harder to fall back asleep. ptsduk.org

How to Actually Fix It (No, Really)

1. Morning Walks Are Your BFF - Take a 20–30 minute in the morning. Struggling and getting the kids out the door? I hear you - If you can take a morning meeting on a walk, or even just get a few minutes of movement first thing before starting the grind (think some jumping jacks or squats while the coffee is brewing is better than nothing. In a perfect world, you snag another one around sunset or in the late afternoon. Morning walks help lower the cortisol built up overnight, and evening walks help you wind down.

2. Meditate Like a Boss- Even a 10-minute meditation session or whatever you find relaxing, it could be yoga, knitting, or just sitting quietly will make a big difference. (spoiler alert, this doesn't include scrolling IG) This helps regulate cortisol levels and keeps stress in check.

3. Set a Consistent Sleep Schedule- Yes, I know you wanna take turns sleeping in and if you're really in the sleep deprived stages of early postpartum, you gotta survive. But If you're a bit farther out, try go to bed and wake up around the same time every day, even on weekends. This trains your body to follow a natural rhythm, making it easier to fall asleep and stay asleep.

4. Snack Smart - Include a small, balanced snack with protein or healthy fat before bed—think a spoonful of nut butter, Greek yogurt, or a hard-boiled egg. This helps keep blood sugar stable, preventing those cortisol-fueled wake-ups and helping you stay in deep, restorative sleep.

5. Create a Sleep-Inducing Environment -Keep your bedroom cool, dark, and quiet. Invest in blackout curtains and a white noise machine if needed. A peaceful environment signals your body that it’s time to rest- why do you think this is what we do for our kids?

6. Limit Stimulants Before Bed- Avoid caffeine, alcohol, and heavy meals at least 3 hours before bedtime. These can spike cortisol levels and disrupt sleep. ALSO! I know the only time you have to yourself is after the kids go to bed, and I know you wanna eat the snacks and scroll IG. But for the love of she-god get the EFFFFF on your phone at least 15 minutes before bed.

7. Get Out of Bed If You Can’t Sleep- If you wake up in the middle of the night and can’t fall back asleep, get out of bed. Do something relaxing until you feel sleepy. Lying in bed stressing about not sleeping only makes things worse. The Sun
