Which body parts are most affected by chilblains?

Chilblains, also known as pernio, are painful inflammations that occur on the skin in response to exposure to cold and damp conditions. The body parts most commonly affected are those that are most prone to cold exposure and that have a smaller blood supply during low temperatures.

Ears and fingers are particularly susceptible because both areas are often exposed and can become cold quickly. The blood vessels in these areas may constrict in response to the cold, leading to reduced blood flow and the potential for chilblains to develop. Once these body parts are warmed up again, the blood vessels may swell, leading to the characteristic painful swelling and itching associated with chilblains.

While other body parts such as feet and hands are also affected by cold conditions, ears and fingers stand out as the most commonly cited locations for chilblains due to their specific vulnerability and susceptibility to cold exposure.
