3 Reasons You Wake at 2 AM

If your eyes pop open between 2 and 4 AM, you’re not alone. For many women in perimenopause, this frustrating wake-up window is a sign that the body’s natural rhythms are out of sync. Here are three common reasons—and what you can start to shift tonight.

1. Blood Sugar Dips and Cortisol Surges

When blood sugar drops too low overnight, the body releases cortisol to raise it back up—pulling you out of sleep in the process. Evening protein and eating your final meal 3–4 hours before bed can help keep levels steady.

2. Low Progesterone and a Restless Mind

As progesterone declines during perimenopause, GABA—the brain’s primary calming neurotransmitter—often declines too. The result: a mind that races at night even when you’re exhausted. Supporting GABA production through rhythm, breath, and nutrient-dense foods can help restore calm.

3. Gut–Brain Communication Disruptions

Your microbiome plays a surprising role in sleep and mood regulation. Imbalances in gut bacteria can increase stress signaling through the gut–brain axis, affecting both cortisol patterns and nighttime rest. (You can read more about this connection in my article on the Gut–Brain Axis HERE.)

✨ Pro Tip:
Some find that taking ProBioPure Daily each morning supports regularity, microbiome balance, and a greater sense of calm throughout the day—laying the foundation for better sleep at night.
