Causes of Chilblains and Raynaud's
Causes of Chilblains
According to research, chilblains are caused by the narrowing (constriction) of the small blood vessels under the skin when exposed to cold. When rewarming occurs, these blood vessels may widen, resulting in blood leakage that causes skin swelling and irritation.
Some people are predisposed to chilblains because of allergies to colds, hormonal changes, or genetic predisposition.
They can affect people of any age, but they are more common in middle-aged adults and uncommon in children. Chilblains are more common in women than in men.
The following are some of the risk factors for chilblains
- Tobacco Use Poor Nutrition
- Clothing that is too small
- Farmers, mountaineers, and fishermen are examples of occupations or professions that require frequent exposure to cold, damp conditions.
