Chilblains (/ËtÊÉªlbleÉªnz/) â also known as pernio, Chill Burns and perniosis â is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot.
Doctors aren't entirely sure what causes chilblains. The condition tends to develop when a person is exposed for a period of time to cold but not freezing conditions -- that is, temperatures from 32 to 60 degrees Fahrenheit (0 to 15 Celsius) [source: NIOSH].
