Postpartum Night Sweats: Why It Happens and How To Treat It?

Postpartum night sweats are one of those unexpected surprises that no one really warns you about.

For most moms, night sweats peak within the first two weeks after delivery. Gradually, the condition improves as hormone levels stabilize. However, some women may also experience night sweats for up to six weeks postpartum.

Read this article to explore why postpartum night sweats happen. Also learn what’s actually going on in your body and how to get some relief.

If you are lately waking up soaked in sweat, it’s not because of other factors—but because your body is adjusting to some significant hormonal changes after delivery. Here are the possible reasons why postpartum night sweats might be happening to you.

During pregnancy, your estrogen and progesterone levels are indeed very high. However, after delivery, these hormones drop suddenly, which triggers a variety of postpartum symptoms—including night sweats. In fact, according to the American College of Obstetricians and Gynecologists (ACOG), it can take several weeks for hormone levels to regulate.

During pregnancy, your body also retains extra fluids to support the baby. But after delivery, your body tries to eliminate that excess fluid through urine, sweat, and breast milk. Shockingly, about 35 percent of new moms experience excessive sweating in the first two weeks postpartum.

If you’re breastfeeding, prolactin rises while estrogen stays low. This hormonal imbalance eventually increases sweating. This happens especially at night because at that time the hormone production fluctuates the most.

After childbirth, your metabolism also speeds up to help your body recover. In simple words, this means your body temperature also fluctuates more than usual, thereby making you sweat more.

The truth is—you cannot completely stop night sweats. But you can make them more manageable. Here are a few tips on how to stay cool and comfortable.

Since your body is losing a lot of fluids, it is essential to drink plenty of water to keep your body hydrated. It is recommended to drink at least 8–10 glasses of water daily, especially if you’re breastfeeding. Did you know hydration also plays a big role in regulating postpartum hormone shifts and reducing overheating?

Another helpful tip is to wear loose and lightweight cotton pajamas instead of synthetic fabrics that trap heat. Besides, also switch to lightweight and moisture-wicking bedding that will help absorb sweat.

The best approach to cool down your room is to lower your thermostat or use a fan to improve air circulation. Ideally, it is recommended to keep the bedroom temperature between 16–19°C for better sleep. You can even use a cooling mattress pad for added relief.

Certain triggers, including spicy foods, caffeine, and alcohol, can increase body temperature, thus worsening night sweats. Therefore, always consider incorporating light, cooling foods such as fruits, vegetables, and protein-rich meals in your everyday diet.

Consider taking a lukewarm shower before sleep, which will significantly help lower your body temperature. However, make sure to avoid very cold showers, as they can shock the body and trigger a heat rebound effect.

Postpartum night sweats are a normal part of your body’s recovery after childbirth. While the symptoms usually fade within a few weeks, simple lifestyle changes such as staying hydrated, wearing breathable clothing, and cooling your room can provide you instant relief. However, if excessive sweating continues beyond two months or is accompanied by fever, chills, or unexplained weight loss, make sure to consult your doctor.
