The temperature difference between autumn and winter is big, what should I do if my skin is dry and itchy?
Recently, the temperature difference between cold and hot is large, which causes some people with unstable skin condition to have symptoms such as dryness, itching, desquamation, etc. Not only does the body catch broken skin, but it is even more tragic after not putting on makeup, and it can't float on the face evenly. Huang Yong, a dermatologist, said that the temperature difference between autumn and winter is large, because the water content in the air is reduced, which makes the skin's water evaporate. It is important to replenish water, but the key point is to lock the water, otherwise the replenishment speed can't keep up with the speed of water shortage, and the skin will still be sensitive and dry.
Hot and cold accelerate water loss to stimulate skin inflammation and dryness
The causes of skin dryness can be divided into internal and external causes. The internal cause is that water disappears through the skin, which stimulates the immune system to cause inflammatory reaction and produce histamine, while the external cause of hot and cold and dryness will accelerate this cycle, leading to skin dryness and itching in autumn and winter. Nutritionists say that the skin has layers of structure, which is most related to water. From the inside out, it is sebaceous glands, dermis and stratum corneum. Sebaceous glands secrete sebum to protect and moisturize the skin and prevent water evaporation. The dermis contains the most water, among which hyaluronic acid and collagen are responsible for storing water; The stratum corneum is the outermost, and the water content is related to the dryness of the skin.
Replenishing moisture to moisturize the skin also needs to lock in moisture.
The general public knows to moisturize, rebuild the skin barrier, or maintain it through diet and work and rest adjustment. The nutritionist emphasizes that besides replenishing moisture, the most important thing is to lock in moisture. If moisture is not locked in the skin, it will only evaporate and the skin will remain dry and rough. It is suggested that natural oils, such as sheep oil and horse oil, should be selected for maintenance, or emulsion containing ceramide should be used to fill the gaps in the stratum corneum and establish a water-blocking barrier.
Rub the emulsion immediately after taking a bath to retain moisture
Sheep oil and horse oil emulsion can be sprayed on the skin before use to increase the extensibility of oil, or after taking a shower, apply the oil emulsion directly and then dry it, so you don't have to worry about getting too greasy and contaminating clothes. You can also take a bath with bath oil, which also has moisturizing effect. Patients with atopic dermatitis, psoriasis, diabetes, and kidney dialysis should pay special attention. In autumn and winter, the skin is easy to dry and itch, so we must choose appropriate emulsion maintenance.
In addition to emulsion maintenance, seafood and spicy food containing histamine should be avoided in diet, and the bath water temperature should not be too high. People who are afraid of cold can turn on the heating in the bathroom, and the doctor of Huang Yong University reminds them, otherwise the high water temperature will cause the loss of stratum corneum. If the cold current strikes, people who need to turn on the heating should replenish water properly or use a humidifier to avoid the indoor dryness and the evaporation of skin moisture.
