Chilblains are itchy, painful, blister-like swellings of the skin, often on hands and feet, especially on fingers and toes, ears and nose. They develop when blood vessels contract as a result of cold and damp temperatures and the tissue behind them is no longer supplied with sufficient oxygen and becomes inflamed. The cold-related circulatory disorders can already occur at temperatures around freezing point, e.g. during winter sports. Chilblains usually disappear after a few weeks. If the endangered body parts are repeatedly exposed to cold without protection, the swelling can become chronic. Warmth and vasodilatory drugs support the healing process.
You can recognize chilblains as doughy, painful, itchy or burning inflamed skin areas. They can be swollen and have blisters or red to blue-violet spots. Prominent areas can indicate an inflammation.
The best protection against chilblains is warm clothing. Headgear is especially important, as the body radiates a large part of its heat through the head. Chilblains on the feet or hands can be promoted by wearing tight shoes or gloves. Constricting bracelets, stocking cuffs, etc. also inhibit blood flow to the extremities. In general, exercise keeps the blood circulation going. Abstaining from nicotine can also reduce the risk of chilblains. Alcohol should also be avoided when staying in the cold, as its vasodilatory effect causes valuable body heat to be lost more quickly.
Chilblains can develop wounds and should be treated immediately by a doctor. If cold-related swellings occur repeatedly, a visit to a doctor is also advisable, as the tissue can be damaged. The administration of vasodilatory drugs or blood circulation-promoting ointments can be useful in the case of chilblains.
Ginger tea heats up chilblains. Since ginger has a positive effect on blood circulation, it can improve oxygen supply to the corresponding part of the skin.
