Why is My Baby’s Sweating While Sleeping?

Does your baby sweat buckets?

When my little girl is small, she’s like a trickling faucet. The AC is at full blast and my baby’s head is sweating while sleeping.

Before long, her hair is soaked. She’ll then wake up dripping in sweat. Just then I got worried. Is there something wrong?

 If you want to know the answer, then read on.


​The Reason behind Baby’s Head Sweats

• Warm room

So your kid is breaking sweat? The first thing that you must look into is the room temperature.


Your child is sweating because the room is too warm. Adults might feel OK with the ambient temperature but not your child.

Babies love it cool.

Baby’s sweat is a warning sign that the room is too warm or that she is overdressed for the weather.

• Baby’s body is still developing

Profuse sweating is usually normal for little kids because they are still developing. Babies have higher heart rate than toddlers. Consequently, toddlers’ heart rate is faster as compared to adults.

Which means:

Higher heart rate equals to more rapid blood flow and a greater likelihood to sweat.

But don't worry, full-term babies have normal functioning sweat glands. The sweat glands in the head are also the most active during this stage.

Also, small children do not toss and turn while asleep, making their heads break down in sweat.

• Mom’s caffeine intake

If you are breastfeeding, check your diet. Do not drink caffeine-containing drinks. Caffeine can transfer to breast milk.

Once consumed, caffeine can contribute to your baby’s head sweating. It will also make her irritable and fussy.

​Medical Causes Behind Baby’s Head Sweating While Sleeping

Sweats are healthy. It just means that your child is responding to the warm weather.


If your child’s breaking in sweat much more than other kids, these are the probable reasons.

# Fever - Check your baby’s body temperature using a forehead thermometer. Fever can contribute to increased sweating.

# Hyperhidrosis - If you have sweaty armpits, hands, and feet, chances are you have hyperhidrosis. Your baby must have taken it from you, that’s why she tends to sweat profusely even in a cold room.

There is a remedy for hyperhidrosis for adults but not for children. If your child suffers from hyperhidrosis, I suggest that you just manage her sweats through cool clothing.

# Sleep apnea - On a rare occasion, your baby can sweat profusely if he is suffering from sleep apnea. His body is in distress. Her breathing is labored, her heart is working harder, that’s why he is sweating.

Sleep apnea means that the baby has stopped breathing for a few minutes. This happens when baby’s respiration paused longer than 15 minutes.

# Congenital Heart Disease - A small percentage of children who sweats buckets might have a congenital heart disease.

This inborn condition makes the child’s heart work harder than normal, which may result in sweats, especially at night.

Congenital heart disease has other symptoms such as rapid breathing, bluish skin tint, dark blue lips, fatigue, and tiredness.

​7 Tips To Deal With Baby’s Head Sweating While Sleeping

how to stop co-sleeping

Do you tend to change the pillow covers every night due to your child’s sweaty head? Remedy this by doing the following:

1. Choose light colored fabrics

Clothe your baby in natural and light colored fabrics. Dark colors such as black, brown, gray or red traps the body heat in, making her sweat more.

The solution?

A white cotton sleeveless shirt is the best outfit during hot summer months.

Also, do not cover your child from head to toe. What worked for adults might not work for babies. It is best to leave baby’s head uncovered and her clothes loose.

2. Cloth diapers

Disposable plastic-material diapers can trap heat. Diapers also soak up urine and soak up the skin, making your baby uncomfortable.

Your baby’s skin can’t breathe in a disposable diaper. It would be best for your child if he wears cloth diapers during the hottest days of summer.

3. Trim down your baby’s hair

Thick hair can contribute to your child’s sweating. Cut your baby’s hair regularly, especially during warm months.

4. Cool bath

Give your baby a quick bath if he is sweating profusely. Baths are comforting. It will also make your child less fussy.

Baths are the best way to make your child comfortable and to make him sleep as soon as possible.

5. Invest in an air-conditioning unit and a room thermometer

Find a small AC that can cover your nursery. Before buying an AC, measure first your baby’s room. You’ll need this information to be able to purchase the most efficient and energy-saving AC.

Also, room thermometers are cheap. Invest also in at least one unit.

6. Hydrate your child

Give your baby lots of water even if she doesn’t look thirsty. Make it a habit of offering her water, until drinking water becomes habitual to your little child.

Replace all those sweats by just drinking water, not soda, ice tea or shakes.

7. Remove all beddings

You might get worried that your dear child feels cold at night. Babies have a higher tolerance to cool temperature. Don’t make the mistake of bundling your baby in a thick duvet, pillows, and blanket. 

Remove all of them. Nothing but the mattress and the crib sheets must remain. 

All these beddings can obstruct air circulation, making your child feel warm.


If your baby is still sweating profusely despite you making the above recommendations, then take him to his doctor.

It is only a doctor that can diagnose the reason behind your child’s sweats.


Be observant; ask questions but don’t sweat the small stuff.
