Watching my little baby sleeping like an angel, how cute and adorable the sleeping little face is. Finding him drenched in sweat in the middle of the night, it is disturbing and this might interrupt my little baby’s sleep.

Temperature - checked.
Clothes and blanket - checked.

The weather is not that hot, but why little baby sweat a lot when sleeping?

A baby’s metabolism is higher than toddlers, it is normal for little babies because they are still growing. The hair follicle and sweat gland of a baby’s head area is more than the baby’s body, it is causing a baby sweats a lot especially on the head part. Furthermore, a baby’s autonomic nervous system is not well developed yet, they are sensitive towards the temperature and humidity of the environment; it may cause a baby sweat when there is only a little change.

This is actually a normal phenomenon, and there is nothing to worry about.
So what's the Reasons Baby Sweat when Sleeping

  1. High metabolism
    A baby’s metabolism is higher than toddlers, a baby’s autonomic nervous system is not well developed yet, they are sensitive towards the temperature and humidity of the environment; it may cause a baby sweat when there is only a little change.

  2. Overdressed / thick blanket
    The temperature to too warm, just this simple reason. Make sure not overdressed your baby and putting too much thick blanket on them. Check your baby temperature by touching their neck or back, if their back/neck is sweating, means the baby is feeling too warm.

  3. Meal before sleep
    After having a meal, baby’s body generates heat to digest food, this is one of the reasons why baby sweat when sleeping.

  4. Poor air ventilation
    Make sure the indoor air ventilation is good, and room temperature is not too high, this will ensure a baby sleep tight in the room.

  5. Over exercised
    This might happen to some energetic baby, when baby exercise or moving too much in the morning, their body will release the excessive heat when they are sleeping at night.


What shall I do when my baby is sweating?

  1. Make sure it is not a hyperhidrosis
    Hyperhidrosis might happen when a baby is not getting enough outdoor activity, sun your baby 10 minutes per day, and make sure there is enough calcium being taken. If excessive sweat happens constantly, remember to consult a doctor.

  2. Not overdressed
    Make sure not overdressing your baby at night, keep him warm by wearing proper amount of clothes and blanket. Using too many layers will make the baby sweat when he is sleeping.

  3. Bath or change baby’s clothes
    Make sure bath your baby or change his clothes when they are sweating a lot. Keep their skin surface dry to avoid skin disease. When buying your baby some clothes, remember to buy baby clothes come with 100% cotton or with breathable material.

  4. Consuming enough water/breastmilk
    This is very important especially for babies eating staple food; the maximum amount would be 30cc of the baby’s weight. Eg: for a 10kg baby, (10kg * 30cc =300cc), and to be separated into a few times daily.

  5. Temperature regulating and anti-bacteria bedding
    Some little baby gets to sweat a lot at night, get them some temperature regulating bedding, like a pillow or mattress will make your baby have a better sleep at night. An anti-bacteria function is really important to make sure to keep your baby out of dust mite.


A newborn baby spends almost 4/5 of the time sleep a day, a good environment always keeps them growing healthy and happily!
