How to prevent frostbite in winter

Chilblains are a very common physical symptom in winter. If frostbite is not treated and controlled promptly and effectively, it may cause serious damage to the body. So you must pay special attention. Especially those who have poor physical resistance should pay more attention to protection. So what should we do to prevent frostbite in winter? Let us introduce it below.

Chilblains are common in early winter and early spring, and are more common in children, women and people with poor peripheral blood circulation. These patients often have symptoms such as cold skin on the extremities, cyanosis of the extremities, and excessive sweating. Skin lesions often occur on the fingers, back of hands, face, ears, toes, edges of feet, heels, etc., and are often distributed on both sides.

The common lesions of frostbite are localized congestive dark purple-red raised edematous erythema with unclear boundaries, bright red edges, a tense and shiny surface, and a soft texture. Local pressure may cause the color to fade, and the red color will gradually return after the pressure is removed. In severe cases, blisters may occur, which may rupture to form erosions or ulcers, and may leave pigmentation or atrophic scars after healing. There is obvious itching, which is aggravated by heat and causes pain after ulceration.

There is a special type of frostbite that is more common on the thighs of women. Clinically, there are characteristic bluish-red infiltrative macules symmetrically distributed on the lateral aspect of the thigh due to excessive obesity, occasionally with secondary ulcers and often combined with follicular keratin plugs. These lesions were entirely related to cold exposure and resolved in a warm environment.

There are several ways to prevent frostbite:

Strengthen exercise and nutrition, improve physical fitness, promote blood circulation, and improve the body's adaptability to cold;

In cold seasons, you should pay attention to keeping warm locally, and gloves, shoes and socks should not be too tight;

The frozen part should not be baked or soaked in hot water immediately;

Apply vaseline or other oils to areas that are susceptible to cold to protect the skin;

Frequent local massage and warm water bath to improve blood circulation;

When chilblains first appear, use a hair dryer to blow and rub them every night, and they will be gone in a few days.

When frostbite first occurs, apply hot vinegar. After the vinegar dries, apply it again several times a day and you will see results.

What you need to do to prevent frostbite in winter is what is introduced above. If you can do the above mentioned things well, you can prevent frostbite from happening. It is very important for health care. In addition, in normal times, you should pay special attention to taking care of your body, and seek timely treatment and control when symptoms of illness occur.
