As a doctor, I’ve spent countless hours counseling patients on the importance of sleep. I’ve explained how sleep affects everything—our hormones, our mental health, our metabolism, and our ability to function as humans. I thought I understood it all. But nothing prepared me for the moment I became the patient. It started subtly—a few restless nights here and there.
Then, like clockwork, I began waking up at 3 a.m. every single night. Not because of hot flashes or night sweats (the usual suspects of perimenopause), but for no apparent reason. Just me, wide awake in the dark, wondering: Why is this happening to me?
The Start of a Sleepless Journey
It was during my early 40s when this relentless pattern emerged. I wasn’t stressed, my bedroom was a sanctuary of perfect sleep hygiene, and I didn’t consume caffeine late in the day. Yet there I was, staring at the ceiling night after night, unable to drift back to sleep.
At first, I brushed it off as part of the occasional sleeplessness we all experience. But as the weeks turned into months, I noticed the ripple effects: fatigue during the day, difficulty focusing, mood swings, and a nagging sense of frustration. I couldn’t help but wonder—was this perimenopause, the life stage I had counseled so many women about, finally showing up in a way I didn’t expect?
Why 3 a.m.? The Biology Behind the Wake-Up Call
To understand why I was , I dove into the research. What I found was both illuminating and humbling. The culprit? Hormonal changes and their intricate relationship with the body’s circadian rhythm.
Here’s why this happens:
Progesterone is a calming hormone that promotes restful sleep. During perimenopause, its levels begin to fluctuate and decline, making it harder to stay asleep.
Cortisol Dysregulation:
Cortisol, the stress hormone, naturally peaks in the early morning hours to help us wake up. However, during perimenopause, cortisol regulation can go haywire. This can lead to waking up too early, even when your body isn’t ready to start the day.
Melatonin Production Drops:
Melatonin, the hormone that regulates our sleep-wake cycle, also decreases as we age. With less melatonin, falling back asleep after waking up becomes more difficult.
Blood Sugar Imbalances:
Perimenopause can cause fluctuations in blood sugar levels, which may trigger a middle-of-the-night wake-up call. If blood sugar drops too low, it signals the body to release cortisol and adrenaline, jolting you awake.
Overactive Mind:
Hormonal shifts can increase anxiety and make the mind race, particularly in the quiet hours of the night. Even if you don’t feel consciously stressed, your brain might still be “on,” replaying the day’s events or worrying about tomorrow.
Why Sleep Matters Even More During Perimenopause
I knew sleep was important, but experiencing the lack of it firsthand during perimenopause deepened my understanding of just how critical it is. Sleep is not just a luxury; it is a biological necessity. Here’s why it’s even more essential during this phase of life:
1. Hormonal Balance:
Sleep plays a vital role in regulating hormones, including estrogen, progesterone, and cortisol. Poor sleep exacerbates the natural hormonal fluctuations of perimenopause, creating a vicious cycle.
Perimenopause is already a time of increased vulnerability to anxiety and depression due to hormonal changes. Sleep deprivation intensifies these challenges, leading to irritability, mood swings, and emotional instability.
3. Cognitive Function:
Brain fog and memory lapses are common during perimenopause. Sleep is essential for cognitive processes like memory consolidation, problem-solving, and focus.
4. Weight Management:
Sleep deprivation disrupts hunger hormones (leptin and ghrelin), increasing cravings for sugary and high-calorie foods. It also contributes to insulin resistance, making it harder to maintain a healthy weight.
5. Physical Health:
Chronic poor sleep raises the risk of long-term health issues such as heart disease, diabetes, and osteoporosis, all of which are concerns for women in perimenopause.
6. Energy and Resilience:
Without restorative sleep, even daily tasks can feel overwhelming. Sleep replenishes your energy reserves and enhances your ability to cope with life’s demands.
How I Took Control of My Sleep
After months of struggling, I decided it was time to practice what I preached. I implemented a combination of strategies to reclaim my nights and, ultimately, my days. Here’s what worked for me:
1. Rebuilding My Sleep Environment
I invested in blackout curtains to eliminate even the faintest light.
I kept my bedroom cool (65°F/18°C) to combat nighttime restlessness.
I introduced calming scents, like lavender, to signal to my brain that it was time to relax.
2. Tuning My Evening Routine
I established a consistent bedtime and wake-up time, even on weekends, to reset my circadian rhythm.
I stopped using screens at least an hour before bed to reduce blue light exposure and allow melatonin production to kick in.
3. Supporting My Hormones
I consulted a functional medicine practitioner who recommended a low-dose bio-identical progesterone cream to help with sleep and overall hormonal balance.
I added supplements like magnesium glycerinate, which promotes relaxation and sleep.
4. Addressing Stress and Cortisol
I began practicing mindfulness meditation and deep breathing exercises daily to lower cortisol levels.
Journaling before bed helped me process my thoughts and worries, preventing a racing mind from keeping me awake.
5. Optimizing Nutrition
I focused on blood sugar stabilization by eating balanced meals with protein, healthy fats, and fiber.
I avoided alcohol and caffeine in the late afternoon and evening, both of which disrupt sleep.
6. Using Natural Sleep Aids
When I still struggled, I used melatonin supplements occasionally to support my sleep-wake cycle.
Herbal teas, like chamomile or valerian root, became part of my evening ritual.
7. Getting Professional Help
Finally, I sought professional guidance to rule out underlying issues like sleep apnea or restless leg syndrome, which can mimic perimenopausal sleep disturbances.
Tips for Women Struggling with Sleep During Perimenopause
If you find yourself waking up at 3 a.m. or struggling with sleep during perimenopause, know that you are not alone. Here are some actionable tips:

Closing Thoughts
