The World Health Organization defines an infant’s normal temperature between 36.5 and 37.5 degrees Celsius. Those babies who have a temperature that drops below this are going through hypothermia, and need to be kept warm. Babies need to have warm temperatures when first born, or else there is a risk of neonatal hypothermia. Those babies born prematurely are at an even greater risk since they do not have the body fat needed to regulate their own body temperature. The warmer, which makes use of infrared radiant heating, ensures that the baby’s body is at a warm and constant temperature.
