Why Does My Baby Sweat So Much From the Head?

Excessive head sweating in babies can be a source of worry for many parents. 

In this article, we’ll explain why this happens, discussing baby’s thermoregulation, common reasons for excessive head sweating, and less common causes including certain medical conditions. 

We’ll also provide practical advice on managing your baby’s sweating and indicators on when it would be wise to seek medical advice. 

Our aim is to provide reassurance and guidance to parents dealing with this often misunderstood aspect of baby care.

Baby’s Thermoregulation: An Overview

Thermoregulation refers to how the body maintains its core internal temperature. 

In newborns and infants, this process is still developing and can be less efficient than in adults. 

For instance, babies can lose heat rapidly, almost four times faster than adults. 

This is why it’s important to keep babies at a comfortable temperature and to avoid overheating.

Sweating is one of the ways the body cools itself down. 

When the body’s internal temperature rises, the sweat glands produce sweat, which then evaporates and cools the skin. 

Babies, like adults, sweat to regulate their body temperature. 

This is especially common during hot weather, during physical activity, or when they are overdressed.

You may notice that your baby sweats a lot from their head. 

This is because the sweat glands in a baby’s head are more active than those in other parts of the body. 

It’s also where they can lose the most heat, which makes it a critical area for cooling down.

Common Reasons for Excessive Head Sweating in Babies


Sweating is the body’s natural response to becoming too hot.

Overheating in babies can be dangerous because they’re less able to regulate their body temperature than adults.

This can happen if babies are overdressed, or if their environment is too warm​​.


Crying can make a baby feel hot, leading to sweating. This effect is more common when a baby cries very hard or for a long period​​.


Babies may sweat when they have a fever or when the fever breaks. Fever may indicate that the baby has an infection​.

Idiopathic Hyperhidrosis:

This is a condition characterized by excessive sweating without an underlying medical condition or clear cause.

The sweat glands are more active in this condition, possibly due to increased activity of part of the nervous system​.

Sleep Apnea:

Sleep apnea is a condition where a person stops breathing during sleep.

It’s more common among premature babies and there may be a link between sleep apnea and Sudden Infant Death Syndrome (SIDS)​.

Less Common Causes of Excessive Sweating

Medical Conditions:

Certain medical conditions like heart disease, cancer, endocrine system disorders, glucose control disorders (such as diabetes), and lung diseases can cause excessive sweating. 

Infections can also lead to sweating​​.

Birth Abnormalities and Genetic Differences:

Various genetic disorders can cause babies to sweat more than usual. 

Cold-induced sweating syndrome and Apert syndrome are two examples. 

These conditions typically present with other symptoms as well​1​.

Secondary Hyperhidrosis:

This is excessive sweating due to an underlying medical condition. 

Some conditions that might cause secondary hyperhidrosis include Acromegaly, Diabetic hypoglycemia, Hyperthyroidism, Leukemia, Lymphoma, Neurologic disease, and Pheochromocytoma (a rare adrenal gland tumor) among others. 

Medication side effects can also lead to secondary hyperhidrosis​​.

How to Manage Your Baby’s Sweating

If your baby sweats a lot, especially from the head, there are several strategies you can use to help manage this. 

First, ensure your baby is dressed appropriately for the temperature. 

Overdressing can cause your baby to overheat and sweat excessively. 

Opt for lightweight, breathable fabrics, and adjust layers based on the weather and your baby’s comfort.

Try to keep your baby’s environment at a comfortable temperature. 

In hot weather, use fans or air conditioning to keep the room cool, and provide plenty of fluids to prevent dehydration. 

If possible, avoid going out during the hottest part of the day.

Regular baths can also help keep your baby cool and clean, particularly if they are sweating a lot. 

However, avoid using harsh or fragranced soaps that might irritate your baby’s skin.

When to Seek Medical Advice

While it’s usually normal for babies to sweat, particularly from their head, there are instances when excessive sweating could indicate a health issue. 

If your baby’s sweating is accompanied by other symptoms such as rapid breathing, a rapid heart rate, or poor weight gain, it’s important to seek medical advice, as this could potentially be a sign of a heart condition.

Additionally, if your baby seems to sweat excessively even when it’s not hot, or if they sweat a lot during their sleep, it would be a good idea to discuss this with a healthcare provider. 

It could be a sign of an underlying health issue, such as hyperhidrosis (excessive sweating), or it could be related to a sleep disorder.

Remember, if you’re ever in doubt about your baby’s health, it’s always best to consult a healthcare provider. 

They can provide guidance and reassurance, and help ensure your baby is healthy and comfortable.

Frequently Asked Questions (FAQs:)

Q1: Can excessive head sweating be a sign of an underlying health issue?

A1: While excessive head sweating can be normal in babies, in rare cases, it might be a sign of a medical condition like hyperhidrosis or a heart condition. If your baby sweats excessively not just from the head, but also from other parts of the body, or if they exhibit additional symptoms like rapid breathing or poor growth, you should consult a pediatrician.

Q2: My baby sweats a lot during sleep, but not much during the day. Is this normal?

A2: Yes, it’s normal for babies to sweat during their sleep as they tend to overheat more easily. This is because their bodies are still learning how to regulate their body temperature. However, if the sweating is excessive or if you have any concerns, it’s best to consult with a healthcare professional.

Q3: Can I use antiperspirant on my baby to reduce sweating?

A3: Antiperspirants are not recommended for babies. Their skin is very sensitive and such products can cause irritation. Instead, dress your baby in breathable fabrics and keep their environment cool to help manage sweating.


To wrap up, excessive head sweating in babies can be attributed to various factors, most of which are quite normal. 

However, understanding these causes, knowing how to manage them, and recognizing when to seek medical advice are important. 

If you ever have concerns about your baby’s sweating, don’t hesitate to consult a healthcare professional. 

Your vigilance and care are instrumental in ensuring your baby’s comfort and well-being.
