What causes dry skin in winter?

Winter compared to several other seasons, it can be said that it is a very unique season, in the winter we can see the phenomenon is very peculiar, and even many animals will choose to hibernate in winter, and in winter for us there are also a lot of unacceptable phenomena, because in winter ** will be particularly dry, may be very serious static electricity when touching some items. <>

And in winter, it is particularly dry, in fact, it is a very normal phenomenon, because in winter our human body temperature and the external environment have formed a very large temperature difference, everyone must know that the human body is a homeothermic animal, although the external environment temperature is particularly low, but the human body can maintain a relatively healthy temperature, even if the temperature can reach a relatively high temperature, so under such conditions, some moisture on the surface may slowly fly away. Although the temperature is not high, the temperature difference between the inside and outside is very large, and it may be difficult for these humid conditions to stay on the surface of the body. <>

And another reason for the dryness of winter is that due to the special dryness of the external environment, the humid conditions that can basically survive in the air have been frozen by the cold weather, forming a variety of water droplets, so the air is becoming drier and drier, which will also allow our body to exchange the environment with the body surface, which will also cause our body surface to become drier and drier, and many humid conditions become water droplets and slowly leave. Well except for some normal circumstances. In winter, due to the harsh external environment, there will also be some physical abnormalities, such as due to the dry weather, usually do not do a good job of ** care.

A dry condition that leads to a lack of water. <>

Or rather, some cracking. These are all reasons why we are getting drier and drier in our daily lives. And in the winter it also requires very strict work.

It is likely to be during normal work and sleep. Let ** also become drier and drier. Without a good night's sleep, blood circulation will not be very smooth, and that will also lead to dryness.

Due to the temperature. This is due to the fact that the stratum corneum is relatively thin and does not have a certain amount of emollient. The climate in winter is drier. That's why this is the case.

It is caused by lack of water, no cosmetics, no cream, need to drink more water, and pay attention to the intake of vegetables.

In winter, when the weather is too cold, the water vapor used will quickly condense, which will be particularly dry, and ** will also be affected.

1. ** Factors per se.

1) The outermost layer of the surface is what we often call the stratum corneum, which contains natural moisturizing factors (amino acids, lactates and sugars) that can maintain a certain water content and maintain moisture, and it also has the function of water absorption and barrier protection.

2) The normal stratum corneum usually contains 10 -30 minutes of water, maintaining softness and elasticity. In the cold winter, the blood vessels on the surface of ** are in a state of contraction, the secretion of sebaceous membrane is reduced, and the moisture content of the stratum corneum will be reduced; In addition, aging is also an important cause of dryness, because with age, the moisture content of the stratum corneum will gradually decrease, and when the moisture content of the stratum corneum is less than 10, dryness, tightness, roughness and scaling will occur.

2. Environmental factors.

1) The weather is dry in winter, and the moisture content in the air is relatively low. In winter, it is windier outdoors and many families use air conditioners due to the cold, which also accelerates the loss of body water.

2) In winter, when the weather is cold, everyone will wrap themselves tightly, and there may be friction between clothes to produce static electricity, which also aggravates one of the factors of dryness.
