Waking up multiple times a night drenched isn't a heat problem and it isn't a sleep problem, it's a hormonal signaling problem. In peri- and postmenopausal women, it's almost always declining estradiol and dropping progesterone. And it's resolvable.
Same vasomotor mechanism as daytime hot flashes, but dropped at night because thermoregulation also dips during sleep.
Progesterone plays a calming, GABA-modulating role. As it drops, sleep gets shallower and night sweats more frequent.
Alcohol metabolism drives a histamine and vasodilation surge 4-6 hours after intake, exactly when you're trying to sleep. Often confounds the hormone picture.
Hyperthyroidism produces classic night sweats. Always check TSH.
Persistent night sweats with weight loss, fevers, or fatigue warrant a workup with your PCP. Don't assume hormonal in this case.
For early perimenopause, nightly progesterone alone resolves night sweats and restores sleep depth in many women, without full estradiol.
