What Are Night Sweats in Babies?

Night sweats occur when babies sweat excessively at night while they are asleep. There are various causes of night sweats, and the condition must not be ignored, especially if it persists longer.

Are Night Sweats in Babies Normal?

Sweating while sleeping is a normal phenomenon in babies. However, if your baby sweats a lot while sleeping, it might be a symptom of a health issue he is suffering from, and hence, must not be ignored.

What Are the Reasons for Night Sweating in Babies?

We have listed some of the reasons why your baby might be sweating while sleeping.

1. Movement

When babies are in deep sleep, they tend to sweat, as they do not move as much as adults do. Body temperature may rise when the baby stays in one position for a long time, and sweating is the body’s way of regulating this increase in temperature.

2. Position of Sweat Glands

Unlike adults, babies’ sweat glands are located close to their heads. This causes them to sweat excessively at night, especially because they do not change their head positions while sleeping, as much as they do when they are awake. As mentioned above, sleeping in one position may cause body temperature to rise, and sweating helps ensure that it is regulated.

3. Room Temperature

The temperature of the baby’s room can also make the baby sweat excessively at night, as is the case with adults.

4. Blanket

Covering a baby with a blanket or dressing a baby in too many clothes could easily spike a baby’s temperature. This makes the baby’s body temperature rise and leads to them sweating excessively. Similarly, excessive insulation from bedding can cause thermal stress. In a study it was found that more thermal insulation than was necessary to maintain the lower critical temperature increased the risk of SIDS among newborns in the prone sleep position. 

Suffocation due to the sleeping position of the baby or getting strangled by a blanket can lead to SIDS or Sudden Infant Death Syndrome. If you are watchful, you could notice the baby’s body overheating while he is asleep, which shows up in the form of extreme night sweats.

These are the common reasons why babies sweat could sweat a lot. However, certain health conditions can also be responsible for night sweats in them.

2. Sleep Apnea

Sleep apnea has been detected as one of the causes of excessive night sweating in infants. In this condition, children pause for some time while breathing, causing the body to get overworked. This, in turn, makes the baby sweat abnormally in sleep. Children suffering from sleep apnea also display other symptoms like bluish skin and wheezing, along with night sweats.

3. Hyperhidrosis

It has been observed that sometimes, despite a controlled room temperature, babies sweat at night. This could be because of a condition called hyperhidrosis or excessive sweating. Although it is not a common cause in children, those suffering from hyperhidrosis also have sweaty hands and feet. However, it is not a serious condition and can be cured by a specialist. The treatment may involve a surgical procedure, or may even be cured non-surgically, by applying ointments or administering oral medication. Be sure to consult a dermatologist to determine the treatment your baby needs.

4. Common Cold/Fever

The night sweats in your baby could be because he is fighting the infection that causes the common cold or fever. Your child may then also show other symptoms like a runny/stuffy nose, cough, etc.
