Baby Sweats in Sleep: Causes, Solutions, and Signs of Concern

Many parents notice their baby sweating in their sleep. Let’s dive into understanding the reasons why and when you might need to take action.

Causes of Baby Sweating While Sleeping


The most common reason why babies sweat during sleep is overheating. Make sure your baby’s room is cool and his clothing and bedding are suitable for the room temperature.

Dreams and REM Sleep

Babies, like adults, might sweat during dreams or rapid eye movement (REM) sleep. This is completely normal.

Sleep Apnea

Sweating excessively during sleep could also be a sign of sleep apnea, a condition where breathing temporarily stops. Consult your pediatrician if you suspect this might be the case.

What You Can Do to Help Your Sweaty Baby

Adjust the Room Temperature

The ideal room temperature for a baby’s room is between 68 and 72 degrees Fahrenheit.

Choose Breathable Bedding and Clothing

Opt for bedding and sleepwear made of breathable materials such as cotton to help prevent sweating.

Limit Bedding

Too much bedding can trap heat and make your baby overheat. A sleep sack or swaddle blanket can keep your baby comfortable without making them too hot.

When to Be Concerned

Excessive Sweating

If your baby is excessively sweating even in a cool room with breathable bedding and clothing, it might be best to consult a doctor.

Sweating with Other Symptoms

If sweating is accompanied by other symptoms like snoring, gasping for breath, or daytime sleepiness, it may be worth discussing with a doctor.

Does my child’s excessive head sweating during sleep indicate an issue?

Some babies just naturally sweat more than others, and the head, hands, and feet are common areas where this occurs. However, if your baby’s sweating seems excessive or is accompanied by other symptoms, it’s worth speaking to your pediatrician.

Can teething cause my baby to sweat while sleeping?

Teething can indeed cause sweating in babies. If your baby is teething and sweats more than usual, it’s likely due to the discomfort and body heat generated during the process.

Recognizing When Baby’s Sweating is a Concern

When should I be concerned about my baby’s sweat?

While sweating is generally a normal part of the body’s temperature regulation, excessive sweating along with other symptoms such as fatigue, difficulty breathing, or fever may require a doctor’s attention.

Why is my baby sweating but has no fever?

Sweating without a fever can simply mean your baby is too warm. However, if it is excessive and is accompanied by other symptoms, consult your pediatrician.

What does it mean if my baby has cold sweats?

Cold sweats in babies can sometimes indicate a medical issue, such as low blood sugar or a heart defect. If your baby often has cold sweats, it’s worth discussing with your doctor.

Managing and Treating Baby’s Night Sweating

How can I help my baby if he sweats a lot while sleeping?

There are a few things you can do to help manage your baby’s sweating. You can ensure the room temperature is kept cool and dress your baby in light, breathable clothing. If your baby is teething, consider using teething toys or gels to help alleviate their discomfort.

What should my baby’s room temperature be to prevent sweating?

The ideal room temperature for a baby’s room is between 68 and 72 degrees Fahrenheit. This can help prevent overheating and reduce sweating.

Baby’s Health and Hydration

Can a dehydrated baby sweat?

Yes, a dehydrated baby can still sweat. In fact, sweating may cause dehydration if the lost fluid is not replaced. It’s important to ensure your baby is properly hydrated, especially in warmer weather.

What are signs of severe dehydration in infants?

Signs of severe dehydration in infants include fewer wet diapers, dry mouth and tongue, crying without tears, sunken soft spot on the head, and drowsiness or dizziness.
