Why you wake up at 3am in perimenopause, and what actually helps

The 3am wake-up is practically a perimenopause rite of passage. Two things are working against you at once: dipping progesterone (your natural sleep aid) and hot flashes or a drop in core temperature that nudges you awake right after deep sleep.

What actually helps, in order: keep the room cool (65–68°F), no alcohol after dinner (it fragments sleep even when it helps you nod off), and a consistent wind-down 20 minutes earlier than you think you need. If broken sleep is wreaking your days, ask your doctor about options, including whether hormone therapy is right for you. You do not have to just endure it.
