Chilblains
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.
What does it mean when frostbite turns purple?
Chilblains turning purple is mainly due to the local skin inflammation caused by cold stimulation, where the congestion in the local skin accumulates and cannot be expelled. Chilblains turning purple may be accompanied by local skin itching or pain, thus timely medication is needed for relief. You can apply some protective oils and chilblain creams, and it is important to keep both the whole body and the affected area dry and warm. Gloves and shoes should not be too tight.
Can frostbite be cured completely?
Chilblains can recur because, in addition to cold being the primary cause, many other factors such as the skin's moisture, abnormalities in the microvasculature, autonomic dysfunction, malnutrition, anemia, and endocrine disorders might also contribute to the condition. Additionally, lack of exercise, excessive sweating of the hands and feet, overly tight shoes and socks, and prolonged outdoor work can also promote the occurrence of chilblains. Thus, chilblains are a multifactorial disease. The best way to prevent recurrence is through preventive measures. These include: first, strengthening physical exercise to promote peripheral circulation and enhance the body's ability to adapt to the cold; second, early in the early winter season, it is important to prevent cold, frostbite, and dampness, stay warm, and avoid wearing tight shoes and socks; third, once exposed to cold, one should not immediately warm up by a fire or soak in hot water; fourth, irradiating the affected areas with infrared before winter or frequently soaking feet in hot water can also help in preventing chilblains.
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.
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.
Can frostbite be soaked in hot water?
Chilblains should not be soaked in hot water. Chilblains are generally caused when a part of the body is exposed to low temperatures, causing the capillaries and other small blood vessels to constrict due to the cold. Therefore, suddenly soaking them in hot water can cause these already damaged capillaries to suddenly expand, leading to worsening of the chilblains, swelling, and even infection. If chilblains occur, it is essential to receive proper medical treatment.
Can frostbite be treated with a hot towel compress?
Chilblains are caused by the cold, leading to spasms and contractions in the small blood vessels at the distal and peripheral ends of the human body, causing venous congestion and poor local blood circulation. At this time, using a hot towel for local hot compresses, or using heating pads for local heat application, can dilate local blood vessels, improve microcirculation, and increase blood flow, which helps in treating chilblains.
Can frostbite be soaked in hot water?
Chilblains occur when cold causes the small blood vessels at the extremities and peripheral ends of the human body to constrict and spasm, resulting in venous congestion and poor local blood circulation. Therefore, soaking the affected area in hot water can dilate blood vessels, improve microcirculation, and increase blood flow, which helps in treating chilblains. Adding some traditional Chinese medicinal herbs like safflower, Angelica sinensis, Salvia miltiorrhiza, dried ginger, and aconite to the hot water, which are known for their properties of warming and invigorating the circulation of blood and dispelling cold, can enhance the effectiveness of the treatment.
How to quickly form a scab when frostbite festers?
Frostbite, if the freezing duration is long, the local tissues will become more hypoxic and the cells will be severely damaged. At this point, local blisters, ruptures, erosion, and ulcers may occur. To quickly form a scab at this time, we should operate as follows: first, keep the local area as dry as possible; second, use astringent, drying, and anti-inflammatory ointments on the ruptured areas, such as boric acid ointment, boric acid zinc oxide menthol ointment, erythromycin ointment, mupirocin ointment, etc.
Does soaking feet in ginger treat frostbite?
Soaking your feet in ginger water can effectively help improve chilblains and also achieve therapeutic effects, so it can be done daily. It is still necessary to keep warm and avoid getting cold, because if the condition is too severe, simply soaking your feet can be relatively slow. Foot soaking can only play a temporary role, so more attention is needed usually. You can soak your feet daily, maintaining the water temperature around 40°C. Moreover, the soaking time should generally be controlled between 15 to 30 minutes to effectively help improve the condition. If the chilblains are severe, some medications can be applied for treatment. (The use of medications should be carried out under the guidance of a professional doctor.)
