Baby Sweat So Much

Are you a first-time mom who gets fidgety over your baby’s excessive sweating quickly? You may have probably witnessed some odd behavior your little bundle of joy has been showing lately. However, there’s nothing more terrifying than seeing your baby sweat excessively even while sleeping.

While I admit being a bit nervous when I find my baby in sweaty clothes when he wakes up, I knew then that I had to research to understand the underlying reasons.

5 Possible Reasons Behind a Baby’s Excessive Sweating

Excessive Forehead Sweating

One of the first observations on excessive sweating can be spotted on a baby’s forehead. This is due to the biological structure of babies. While babies are born with sweat glands, they do not function immediately after birth.

According to a study performed by Foster KG, Hey EN, and Katz G, Babies who are less than 210 days in post-conceptual age do not respond to thermal stimuli even when subjected to an environment with a temperature of 37.8 degrees Celsius.

On the other hand, older infants of around 268 days in post-conceptual age demonstrate sweating on the forehead, temple area, and then on the chest. With this biological factor, it is understandable that seeing your baby sweat so much on the forehead becomes worrisome and surprising.

Environmental and Biological Factors

Sweating is also considered as a natural response of the body when the baby is subjected to heat. As with adults, sweat is one natural method that cools the body down. Therefore, it is normal for babies to sweat when placed in a warmer environment.

Moreover, as babies’ temperature-regulating systems have not completely developed yet, they tend to sweat excessively. This is due to the nervous system of the babies which have not fully developed yet.

Besides, you may also be guilty of over bundling your baby during the cold autumn or winter seasons. Note that the ideal room temperature should be around 20 to 22 degrees Celsius (60-72 degrees Fahrenheit) for babies.

It is also essential to know that aside from escalating the baby’s body temperature and causing excessive sweating, over bundling may also lead to overheating and cause Sudden Infant Death Syndrome (SIDS).

If you are worried about how to keep your baby warm but would like to avoid excessive sweating, you may opt to dress him or her in an onesie pajama. Another option is to use a wearable blanket or a ‘sleep sack’ made from 100% cotton material.

Sign on Fever in Babies

The elevated temperature of the body can lead to sweating profusely. Fever is considered a normal and usually positive reaction of your baby’s body when fighting an infection. Due to this body response, body temperature tends to be higher than usual.

To help reduce sweating and lower the fever without resorting to medicine, you may want to place a damp cloth on your baby’s forehead or give him or her a lukewarm sponge bath. However, if your child’s temperature reaches 102 degrees Fahrenheit, it is best to call a doctor.

Hyperhydrosis in Infants

Another condition that may cause excessive sweating on your baby is called pediatric hyperhidrosis. Endocrine dysfunction is regarded as one of the common causes of hyperhidrosis. Another congenital disability called the eccrine nevus is also associated with excessive pediatric hyperhidrosis.

The excessive sweat is typically seen on the palms, feet, and limbs of a child or baby. While the case is relatively common, dermatologist-researchers Christina M. Gelbard, M.D., Hayley Epstein, and Adelaide Hebert, M.D of the University of Houston conclude that the situation is often underdiagnosed in children.

This fact has led this team of dermatologist-researchers to review the different current treatments for pediatric hyperhidrosis, including botulinum toxin injection, topical therapies, systematic therapies, and even surgical options.

If you see your baby sweat profusely even in the cold environment, seeing a pediatrician and a dermatologist would help understand his or her condition. As per the doctors mentioned, if the condition remains untreated, it could interfere with your kid’s daily activities.

Other Medical Conditions

I do not intend to scare you, but give you further information on what could be causing the excessive sweating on your baby. If you noticed that your baby has sweaty and often salty skin, this could be a symptom of certain medical conditions.

Secondary hyperhidrosis, for instance, could be a possible sign of hypertension and hyperthyroidism. Before secondary hyperhidrosis can be ruled out, diagnosis for focal sweat must be ruled out first. In this regard, seeking medical attention would be the best option.

Aside from these, if your baby has constantly salty and sweaty skin, it is best to seek medical attention. These two are among the signs of other medical conditions such as hyperthyroidism, asthma, diabetes, and rickets.


Understanding how your baby perspires helps eliminate unnecessary stress and worries. Keeping his body at optimal temperature will help alleviate sweating and keep him or her comfortable. Learning more about fever in kids and other medical conditions can also be immensely helpful.

It would likewise be helpful to keep in mind the following:

  • Always put the baby’s room temperature between 60-72 degrees Fahrenheit
  • Monitor your baby’s body temperature and see if it goes beyond 102 degrees Fahrenheit
  • Never miss your baby’s regular visit to the pediatrician

I hope that I was able to impart valuable information to you today. It is my goal to empower moms like me on cultivating knowledge about babies and their behavior. If you have any questions, feel free to write them down.
