Children who run hot at night are more common than most parents expect. Babies and toddlers have less developed thermoregulatory systems than adults and generate significant body heat relative to their size. Here is what helps and what is important to know about safety.
Why Children Run Hot
Children have a higher surface area to body mass ratio than adults which affects how they regulate temperature. They also have higher metabolic rates relative to body size. Toddlers in particular generate significant heat during sleep and their temperature regulation is still developing. This means many children are naturally hot sleepers even if their parents are not.
Safety First: Age and Blanket Use
Loose bedding of any type is not recommended for children under 12 months due to suffocation risk. This is a firm pediatric sleep safety guideline. For children under 12 months focus on room temperature, 16-20 degrees Celsius, appropriate sleep clothing, and ensuring the sleep surface itself is cool.
For children over 12 months a lightweight cooling blanket appropriate to their size can be used. The blanket should be lightweight, not excessively large for the sleep space, and the child should be old enough to move it off their face if needed.
Room Temperature
For babies and toddlers the room temperature approach is more important than bedding. Maintaining a bedroom temperature of 16-20 degrees Celsius is the primary intervention. A fan that moves air without pointing directly at the child improves airflow without causing chilling.
