Hypothermia is a body temperature much lower than normal. As the body surface area of a newborn is large in relation to its body weight, it can lose heat quickly, especially in cold environments the temperature of newborn babies tends to fall.
A complication of hypothermia may be hypoglycaemia, high blood acidity, and death. This is why all newborns should be kept warm, and this care begins in the delivery room. The cap or cap is used to prevent heat loss through the scalp.
When the baby, especially a newborn, undergoes medical observation while naked, it should be placed under a device that radiates heat to avoid hypoetry, especially if it is a low birth weight baby.
