Why You Might Experience Night Sweats After Birth

Waking up in the middle of the night drenched in sweat after having a baby? 😰 You're not alone, and no—it’s not just a fluke. Night sweats after birth are incredibly common, but they can feel confusing and even a little alarming if you’re not expecting them.

Let’s break down why this happens, what’s normal, and how to stay cool, comfy, and confident while your postpartum body resets. 

Why Do Night Sweats Happen After Birth?

After giving birth, your hormone levels—especially estrogen and progesterone—plummet rapidly. This drop is your body’s way of shedding excess fluids and returning to a non-pregnant state. The result? You sweat. A lot. Especially at night. 😅

Other common reasons include:

• Fluid retention during pregnancy: Your body stored a lot of water to support your baby. Now it’s trying to let it all go.
• Hormonal shifts: These affect your internal thermostat.
• Breastfeeding: Prolactin (the hormone that supports milk production) also affects your sweat glands.
• Stress and anxiety: New-mom worries can contribute to overheating.

How Long Do Postpartum Night Sweats Last?

Most night sweats ease up within a few weeks to a couple of months postpartum. They usually peak during the first 2–3 weeks when hormonal changes are most intense.

But if they persist past the 6-week mark, especially alongside other symptoms (fever, fatigue, etc.), it’s best to check in with your doctor.

Tips to Stay Cool & Comfortable

Let’s make those sweaty nights a little less frustrating:

• Wear moisture-wicking sleepwear
• Soft, breathable materials like bamboo or cotton can help absorb sweat and keep you dry.
• Layer your bedding
• Use light layers that you can peel off in the night instead of one heavy blanket.
• Stay hydrated
• Ironically, the more you sweat, the more you need to drink! 💧
• Sleep with a fan
• Even better if it oscillates.
• Keep your room cool
• Ideal temp: 65–68°F (18–20°C).
• Shower before bed
• A quick rinse with lukewarm water helps lower your core body temp.
