Frostnip is a mild form of this cold injury.
Children are at a higher risk of experiencing frostbite and frostnip than adults because they experience heat loss from their skin more rapidly.
Those children with disorders that affect circulation, such as diabetes, may be even more susceptible to frostbite and frostnip.
In addition, children from tropical climates may not be able to withstand cold temperatures as well as their cold-climate counterparts, making them more susceptible to frostbite and frostnip at higher temperatures.
Frostnip and frostbite are associated with ice crystal formation in the tissues.
