It can be quite common for infants and young children to become hot during sleep. This can be simply because the room is kept too warm or the bedclothes are too dense, but some children are routinely hot sleepers. Small children cannot always express when they are hot and uncomfortable, so it is important to pay attention and watch for signs that they may be overheating.

A common reason for children overheating is illness or  fever. Fevers in infants can be potentially dangerous or even deadly, so if you notice your baby is extremely flushed and sweating, whether at night or not, it is important to take their temperature to see whether they have a fever.

With older children, particularly teenagers, sleeping hot can be associated with puberty. This is often noticeable around the age of twelve and ends around the age of eighteen, although this is not specific and can vary from child to child.

Controlling your body temperature the right way is important; keeping the room too cold, even with a lot of blankets, can cause insomnia. A cool, even temperature will give you the best chance of a good night's sleep.
