The Reason behind Baby’s Sweating While Sleeping

Most parents are concerned about one major problem and they frequently ask this one question which bothers them a lot:

“Why my baby’s head sweats more than the rest of the body?”

And the answer is that when your child is little most of its sweat glands are present on its head which are super active and can cause increased and profuse sweating.

Babies sweat profusely especially at night one of the reasons being their sleeping position.

Since babies don’t change their sleeping positions too often like adults and sleeps and often spend much more time in slumber which results in a sweaty head of the baby.


There are other factors which contribute to the sweaty head of your baby and as a parent, you might want to know them too in case your baby is experiencing increased sweating because of them and these are:

1. Warm room

So, your kid is breaking a 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.

What should you do?

The first thing you have to make sure that your baby’s room temperature is neither too hot nor too cold. Always make sure that your baby’s room has proper airflow and baby’s night clothing is light.

2. 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 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.

What should you do?

As mentioned above one of the reasons of profuse sweating of baby at night is the fact that the baby is growing up so if your baby gets up in the morning active and happy then there is nothing to be worried about.

3. Mom’s Caffeine Intake

One of the major reasons for your toddler sweating in sleep is that you might be consuming caffeine.

Which means:

Mothers can transfer caffeine to their baby’s body through breastfeeding and babies are very sensitive to caffeine.

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

What should you do?

So, if you are breastfeeding, check your diet. Try to cut down on caffeine at least until you are breastfeeding your child. Do not drink caffeine-containing drinks. Caffeine can transfer to breast milk.

Medical Causes Behind Baby’s Head Sweating While Sleeping

As we have discussed earlier that sweats are healthy. It just means that your child’s body is responding to the warm weather.


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

1. Fever:

Fever can also contribute to increased sweating and most of the time parents are unaware that their baby is having a fever.

What should you do?

First, verify that your baby is having a fever by checking your baby’s body temperature using a forehead thermometer. Then you can place a cool and damp piece of cloth onto the forehead of your baby this will allow her temperature to go down also do not forget to see your baby to the doctor.

2. 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.

What should you do?

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.

Tragically, there are no silver bullets that will "cure hyperhidrosis", however, there are numerous compelling medicines that can diminish the humiliating impacts of profuse sweating.

3. 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.

What should you do?

Newborn children suffering from sleep apnea may require a machine to give breathing help. They additionally may require treatment with prescriptions. Both of these choices have a tendency to be temporary solutions. Newborn child's sleep apnea has a tendency to leave as the youngster develops and grows up.

4. 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.

What should you do?

Albeit numerous babies who have congenital heart disease needn't bother with treatment but some do. However, doctors fix congenital heart disease with catheter method or surgery. Here and there doctors join catheter and surgeries to repair complex heart defects, which may include a few sorts of diseases.

5. Sudden Infant Death Syndrome or SIDS

Which is also known as Cot or Crib death, might also be the reason for your baby’s excessive sweating.

There are several factors which contribute to this syndrome such as sleeping on the stomach or side, premature or defected brain, any respiratory infection and low birth weight etc.

What should you do?

Luckily there are a few things you can do to avoid SIDS to some extent. These are as follows:

Always make sure to put your baby on his back while you tuck it to sleep.

Place your toddler on his belly while he is not sleeping or awake.

Ensure that your baby sleeps over a firm sleeping mattress or surface.

And always try to maintain your baby’s body temperature warm but not too warm.
