Let's talk about chilblains first, which can occur on various parts of the body. The most common cause is cold stimulation, such as redness and itching on the back of the heel, which may be due to occupational or other factors. The heel is often exposed and susceptible to cold, potentially leading to chilblains. This condition can be particularly troublesome but sometimes heals on its own as the weather warms up, though it is prone to recurrence. Treatment may require the use of vasodilators or traditional Chinese medicines that improve microcirculation and invigorate the blood. Regular physical exercise to boost immunity, avoiding cold exposure, and ensuring adequate warmth and dryness are important. Tight shoes and socks should be avoided, and it is not advisable to soak in hot water immediately after getting cold; instead, gradually increase the water temperature. If there is an open wound, appropriate ointments can be applied to promote healing, ensuring the area stays dry to prevent further chilblains. For example, soaking in water daily can be beneficial if there is no open wound, starting with water at 10°C, then increasing gradually to 20°C, and finally 30°C to gradually warm the area and improve blood circulation, aiding in recovery. Additionally, using ointments like chilblain cream can help improve the condition, but the area is still prone to reoccurrence if it gets cold again. Mainly, keeping the area warm and moist is crucial. For open wounds, regular disinfection with povidone-iodine and applying erythromycin ointment to prevent infection may be beneficial. (Please use medications under the guidance of a doctor to avoid inappropriate self-medication.)

Do chilblains recur every year?

Chilblains are caused by the skin being in a low temperature environment. If chilblains occur, the likelihood of recurrence is very high, but it is not absolute. After experiencing chilblains once, if the environmental temperature is relatively low every year afterward and one does not keep warm sufficiently, it is basically possible for the chilblains to recur annually. However, if the climate temperature rises in subsequent years and one pays attention to keeping warm, it is also possible that chilblains will not reappear.

How to treat frostbite in summer?

Chilblains usually occur in early winter and early spring. Therefore, treating chilblains in summer is mainly to prevent recurrence in winter. The routine mainly involves physical exercise. From the perspective of traditional Chinese medicine treatment, there is a concept of treating winter diseases in summer. You can use some Chinese herbal medicines that warm and promote circulation, activate blood circulation and remove blood stasis, and unblock collaterals to relieve pain. These herbs can be decocted and used for foot soaks over a period, which helps to prevent the occurrence of chilblains in winter.

Can ginger be used to rub on frostbite?

If the skin is not broken or ruptured after suffering from frostbite, ginger can be used to rub the affected area. However, the effectiveness of using ginger is not particularly good. But if the skin affected by frostbite is clearly broken or ruptured, ginger should not be used. Using ginger in such cases can cause severe irritation to the affected skin, which may likely lead to a secondary bacterial infection. It is recommended for patients suffering from frostbite to use some ointments that help improve local circulation.

How to prevent frostbite

Frostbite is a skin disease caused by local skin inflammation due to cold weather. Therefore, it is crucial to prevent frostbite by avoiding prolonged exposure to cold, low-temperature environments. If it is necessary to be in such environments, it is essential to keep both the local areas and the entire body warm. You can wear hats, earmuffs, and gloves, and put on thicker shoes and socks. However, shoes, socks, and gloves should not be too tight, as overly tight clothing can also lead to frostbite.

Why does frostbite occur year after year?

Cold is the primary cause of chilblains, but in addition, factors such as the patient's own skin moisture, abnormalities in peripheral microvessels, autonomic nerve dysfunction, malnutrition, anemia, endocrine disorders, etc., may also participate in the development of the disease. Other factors such as lack of exercise, hyperhidrosis of the hands and feet, overly tight socks and shoes, and long-term outdoor work may also contribute to the occurrence of chilblains. Therefore, chilblains are actually a multifactorial disease, making it prone to recurrence.
