Night Sweats During Pregnancy: Causes and What to Expect

Night sweats during pregnancy are common and are primarily driven by hormonal changes — specifically rapid estrogen fluctuations — that affect the part of the brain responsible for regulating body temperature. They are most frequent in the first trimester and can return around delivery. Antiemetic medications prescribed for severe morning sickness can also make them worse. This article explains what causes night sweats in pregnancy and when to speak to your doctor.

TL;DR

• Night sweats in pregnancy are most common in the first trimester, triggered by rapid estrogen fluctuations that affect the brain's temperature regulation center.
• Antiemetic medications prescribed for severe nausea can worsen hot flashes, sweating, and flushing — a finding from a Stanford University study cited in the article.
• Night sweats usually ease after the first trimester but can return around the time of delivery.
• Postpartum sweating is also common as the body adjusts to another major hormonal shift after birth.
• If night sweats are severe or accompanied by other concerning symptoms, contact your doctor.

A Stanford University study found that taking antiemetic drugs can cause night sweats. Women who experience severe nausea early in pregnancy are prescribed antiemetic drugs, which assist to minimize vomiting and upset stomachs. But this drug frequently makes hot flashes, sweats, and flushing worse.

Hormones affect the formation of night sweats, just as they do in women going through menopause or in humans in general as they age or experience other physiological changes. The hormonal shift affects the area of the brain that controls body temperature, leading to increased sweating. Early in pregnancy, night sweats and excessive perspiration usually go away after nine months, but they could come back around the time of delivery. While managing these internal shifts, many women also seek ways to alleviate physical tension; for instance, you might wonder if you can go to the chiropractor while pregnant to help your body adjust to the early changes in posture and bone alignment.

During the first two to three weeks of pregnancy, nocturnal sweats and early pregnancy are common. This is brought on by the body's natural production of estrogen, which fluctuates rapidly. On the other hand, ovulation schedules may also be connected to night sweats. 

Additionally, did you know that after giving birth, sweating could occur for both you and your child? Babies and toddlers sweat more during the night than adults do because they have more sweat glands per square inch of skin. This causes their bedding to get damp, which disturbs their sleep. To keep your little one comfortable and their skin healthy after a sweaty night, choosing the best bath for your newborn will ensure a gentle and soothing cleaning routine. Solutions are available from Wicked Sheets for infants, toddlers, and adults. Mood, heat flashes, and nocturnal sweats can all be impacted by postpartum. This period is a time of major transition for your entire system, making it crucial to also focus on the recovery of your postpartum pelvic floor, which underwent significant stress during pregnancy and birth.

As always, if you have concerns about hot flashes or night sweats, get in touch with your doctor.
