Why do I get night sweats after giving birth?

Question

Accepted Answer

Drenching night sweats in the days and weeks after birth are so common they are practically a rite of passage, and the mechanism is twofold: your body is shedding the extra fluid it carried through pregnancy - through sweat and urine - and estrogen and progesterone crash abruptly after delivery, and abrupt hormone withdrawal drives sweating, exactly as it does in menopause. Sweats are typically worst in the first one to two weeks and fade within a few weeks, though they can linger a month or two, especially with breastfeeding, since prolactin keeps estrogen low.

Management is comfort only: breathable layers and bedding you can strip, a towel on the pillow, a fan, hydration to replace the fluid, and patience. Nothing needs treating in the normal course.

The rule that matters: sweating with a fever is not postpartum sweats - it is infection until proven otherwise. Call your provider promptly for a temperature of 100.4 F or higher, and also for sweating with a red painful breast area, foul-smelling discharge, worsening belly pain, burning urination, or a fast heartbeat - postpartum infections move quickly and all of those need same-day assessment. Sweats that persist past two months, or come with weight loss or a racing heart, also deserve a check - thyroid problems can first show up postpartum. Everything short of those: change the sheets, hydrate, and wait it out.
