According to Julia Dickinson, registered nurse, certified nurse midwife, and director of midwifery at Mount Auburn Hospital, and Dr. Brett Young, MD, interim chair of OB-GYN and an assistant professor at Harvard Medical School, postpartum night sweats are usually not a cause of concern. They explain that experiencing postpartum night sweats is normal and may involve feeling hot, flushed, and sweaty, typically lasting for about three to five minutes and might be followed by brief chills.
