Postpartum night sweats usually peak in the first 1–2 weeks after birth and most often settle down within about 6 weeks, though for some parents they can last up to around 3 months, especially if breastfeeding.

Quick Scoop

  • Typical duration:
    • Most intense in the first 2 weeks postpartum.
* Commonly improve and resolve by about 6 weeks, which is the standard postpartum period.
  • Longer but still “normal” window:
    • Some experts note they can last through the “fourth trimester” (up to roughly 12 weeks) before fully resolving.
  • Breastfeeding factor:
    • Breastfeeding keeps estrogen levels lower, which can make night sweats last longer for some people.

A practical way to think about it: many new moms find they’re drenched most nights for the first couple of weeks, notice things easing by 4–6 weeks, and only occasional warm, sweaty nights by 2–3 months—especially if they’re still breastfeeding.

When to check in with a doctor

Night sweats are usually benign and hormone-related, but you should contact your healthcare provider if:

  • They are still strong and frequent well beyond a few weeks, especially past 3 months postpartum.
  • You also have fever, feeling very unwell, weight loss, new pain, or other unusual symptoms, as these can signal infection, thyroid problems, or other conditions.

Quick comfort tips

These won’t shorten how long postpartum night sweats last, but they can make them more bearable while your hormones reset:

  • Keep the bedroom cool with a fan or lower thermostat.
  • Wear loose, breathable cotton or bamboo sleepwear.
  • Use lighter bedding and keep a spare set of pajamas and a towel by the bed for quick changes.
  • Drink plenty of water to replace fluid lost through sweating.

Bottom line: Most postpartum night sweats fade on their own within about 6 weeks, may linger up to around 12 weeks, and should be discussed with a professional if they’re severe, worsening, or accompanied by other concerning symptoms.
