What causes cracked fingers?

The function of fingers is very important. They can help people make and use tools, and fingers completely obey the command of the brain. However, fingers are also susceptible to functional damage, such as finger mutilation and breakage caused by external force. Finger cracks are a relatively minor finger injury. Let's take a look at the causes of finger cracks.

The main season for the occurrence of finger cracks is winter.

In cold and dry seasons, the skin is prone to dehydration, especially in winter when the incidence rate is particularly high.

Some women experience metabolic disorders and hand clefts after giving birth.

3. Nutritional factors for dry and cracked hands:

Lack of vitamin A and vitamin E can cause cracked hands. You can drink more boiled water, fruit juice drinks, milk, soy milk and other liquids to nourish yin and moisten dryness. Replaces lost moisture.

The occurrence of chapped hands and feet is related to the anatomical and physiological characteristics of the local skin and a variety of external factors, and is also related to the overall condition to a certain extent. The anatomical and physiological characteristics of hands and feet are that the stratum corneum on the palms and heels is extremely thick, with up to more than 100 layers, the keratinocytes are arranged irregularly, and these areas have no hair follicles and sebaceous glands, which limits the retention of local skin moisture and the moistening of the skin by sebum. When affected by various external factors, skin cracking is prone to occur.
