Neonates are prone to rapid heat loss and consequent hypothermia because of a high surface area to volume ratio, which is even higher in low-birth-weight neonates. There are several mechanisms for heat loss: Radiant heat loss: Bare skin is exposed to an environment containing objects of cooler temperature.
Why do newborns lose body heat?
Evaporation. This is the loss of heat from an infant’s wet skin to the surrounding air. Infants lose heat by evaporation after delivery or after a bath. Even an infant in a wet nappy can lose heat by evaporation.
How can you prevent heat loss in newborns?
- Dry the infant with a warm towel.
- Increase the temperature of the delivery room to 26°C.
- Place the infant under a preheated radiant warmer.
- Place the infant on a portable warming pad.
- Swaddle the infant in a warm blanket.
- Wrap the infant in a polyethylene plastic.

Why is it important to prevent hypothermia in the immediate newborn period?
In premature infants, hypothermia increases morbidity and mortality. Hypothermia may be purely environmental or represent intercurrent illness (eg, sepsis). Maintaining an appropriate environmental temperature in the delivery room or operating room is critical in preventing neonatal hypothermia.
Do newborns get cold easily?
A baby’s hands and feet easily get cold and can sometimes turn slightly blue. This is normal and should resolve with warming. It is also a good idea to feel your baby’s nose to see if they are cold. If your baby does feel cold, add another layer of clothing, – but remember never to put a blanket in your infant’s crib.
What’s a good room temperature for a newborn?
Keeping your baby’s room cool, but comfortable is one way to maintain a safe sleep environment. In fact, it’s recommended that babies sleep in a temperature between 68° and 72°F (20° to 22.2°C).
What is hypothermia in newborn?
Definition. Neonatal hypothermia is defined as an abnormal thermal state in which the newborn’s body temperature drops below 36.5 °C (97.7 °F). Progressive reduction in body temperature leads to adverse clinical effects ranging from mild metabolic stress to death.
What are the 4 types of heat loss?
There are four avenues of heat loss: convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction.
How does the body increase heat loss?
The body loses heat through: Evaporation of water from your skin if it is wet (sweating). If your clothing is wet, you will also lose some body heat through evaporation and through respiration (breathing) when the body temperature is higher than 99°F (37°C). … The body loses about 2% of its heat through air conduction.
How do newborn babies lose heat?
Newborns lose heat by evaporation after delivery or after a bath. Even a newborn in a wet nappy can lose heat by evaporation. Radiation. This is the loss of heat from a newborn’s skin to distant cold objects, such as a cold window or wall etc.
Why do they cool newborns?
A treatment that cools the bodies of infants who lack sufficient oxygen at birth brings benefits that last for years, a new study confirms. Infants sometimes develop severe oxygen deficiency during the birth process.
Where do babies lose the most heat?
According to Sey, newborns are even more susceptible to losing heat through their heads than adults. “Newborns typically have a large head compared to their body size, allowing for more heat to be lost,” says Sey.
How will I know if my newborn is cold?
How can I tell if baby is too hot or too cold? The easiest way to tell if your baby is too hot or too cold is by feeling the nape of the neck to see if it’s sweaty or cold to the touch. When babies are too warm, they may have flushed cheeks and look like they’re sweating. An overheated baby may also breathe rapidly.
What temperature is too low for a newborn?
If your baby’s rectal temperature drops below 95°F (35°C), they’re considered to have hypothermia, or low body temperature. A low body temperature in babies can be dangerous, and, though rare, may lead to death. Read on to learn more about low body temperature in babies, including causes and next steps.
Do Babies cry if they are too cold?
The temperature can make your baby cry. They may cry because they are too hot or too cold. If your baby is fussy because of the temperature, there are signs that you can look for. Signs of the baby being too hot are sweating, damp hair, heat rash, or clammy skin.
