What parts of the body are most affected by chilblains?

Chilblains are localized inflammatory responses that occur in small blood vessels when they are exposed to cold temperatures. This condition primarily affects extremities, which have less blood flow and are more susceptible to cold injury. The most commonly affected areas are feet and fingers, as these parts of the body are typically the most exposed to cold and can have reduced circulation in colder conditions.

The feet and fingers have a higher tendency to develop chilblains because of their peripheral location in relation to the heart and their involvement in activities where they may be exposed to cold or damp environments. These areas are often more vulnerable to the impacts of cold weather, leading to swelling, itching, and discomfort associated with chilblains.

While other options mention areas like the chin, ears, legs, toes, and nose, they are less commonly affected by this specific condition, making the feet and fingers the areas most prominently linked to chilblains.
