“Every night at 3:12, I’m wide awake.” Gina’s story.

Why sleep loses its brakes in perimenopause, and how to help your body find them again.

My friend Dana called me on a Sunday afternoon and skipped the hello. “I’m worried about my sister-in-law,” she said, “and I think she’s scared.”

Her sister-in-law is Gina. She’s 47, teaches high school orchestra, and has spent most of her life sleeping like a stone through thunderstorms, toddlers, and a husband who snores.

A few months ago she started waking at 3:12 a.m., heart thumping, mind already drafting tomorrow’s to-do list. Then she checked her sleep tracker and saw it had happened 19 nights in a row.

“I’m in bed by ten, I’m exhausted, and my body just turns on,” Gina told me when we finally spoke. “Is something wrong with my heart, or am I losing my mind?”

Know that 3 a.m. feeling? Wired and tired at the same time, staring at the ceiling while everyone else in the house sleeps.,

Gina’s heart is very likely fine, and her mind is fully intact. What changed is a calming signal her brain leaned on for decades.

Progesterone is often the first hormone to become unpredictable in perimenopause, sometimes years before periods stop. The brain converts some of it into a compound called allopregnanolone, which acts on the same calming GABA receptors that many sleep medications target.

Think of progesterone as the parking brake on Gina’s nervous system. For years it held her steady through the night, and now it’s slipping, so the small rise in stress hormones that naturally comes in the early morning hours is enough to roll her awake.

The Study of Women’s Health Across the Nation, a long-running study funded by the National Institutes of Health, followed thousands of women through midlife. Trouble sleeping, especially waking during the night, became more common as women moved through the menopausal transition.

I’m sharing Gina’s story because the 3 a.m. wake-up is one of the most common things midlife women describe to me, and one of the least explained. Most are told to relax, cut caffeine, and try harder.

This isn’t a willpower issue. It’s a brake that’s wearing thin, and you can add some braking power back.

🍷 First, take an honest look at evening alcohol. A glass or two of wine can help you fall asleep, then fragment the second half of the night as your body processes it, right when your brake is at its weakest.

📱 Second, when you wake at 3 a.m., leave the phone face down and breathe in for four counts and out for six to eight. A longer exhale nudges the nervous system toward its calming side, lending it a little of the braking it’s missing.

If you snore loudly, wake up gasping, or notice a racing heart along with chest pain or dizziness, talk to your doctor soon. Sleep apnea becomes more common after menopause, and if poor sleep has lasted more than three months, ask about cognitive behavioral therapy for insomnia, which is a first-line treatment.

Gina isn’t broken, and neither is your sleep. Your nervous system is learning to rest in a new season, and we’re learning it together.
