As the temperature drops and the temperature difference between day and night increases, our skin also enters a "seasonal mode". In addition to feeling dehydrated and uncomfortable, some skin diseases have also entered a high incidence period, such as cracking, peeling, redness, and itching... The dermatology clinics of major hospitals are experiencing a wave of peak visits, with skin pruritus, atopic dermatitis, urticaria, herpes zoster, psoriasis, and other common diseases. How to take care of the skin to safely pass through the changing season? How to deal with skin diseases correctly? In response, the reporter interviewed relevant experts from Jinan Dermatology Prevention and Treatment Hospital.

High incidence of skin problems in autumn and winter seasons
alcohol moderation for heart health
Recently, citizen Xiao Wang has been troubled by recurrent dry and itchy skin, with blood marks on his body and a significant impact on his sleep at night. Unable to bear the hardships, he ran to the hospital for treatment and found that there were indeed many patients with the same problems as him.

The skin is the largest organ in the human body and the first line of defense against external disturbances. It is directly in contact with the external environment, so it is very sensitive to climate change. "Yu Debao, Vice President of Jinan Skin Disease Prevention and Control Hospital, introduced that with seasonal changes, temperature and humidity decrease, the secretion of sebaceous glands decreases. Most people will feel that the skin is dry, peeling, and dry and lacking oil, which can damage the protective power of the stratum corneum, Keeping the superficial nerve endings of the skin in a more active and sensitive state can easily lead to symptoms such as redness, itching, tingling, and peeling for those who already have problems with their skin barrier function.

In addition, using overheated water for bathing, frequent hand washing, and prolonged exposure to dry environments can also exacerbate skin dryness.
Due to the invasion of the skin immune barrier, some inflammatory skin diseases, such as chronic eczema and atopic dermatitis, are prone to develop or recur during the autumn and winter seasons. Meanwhile, as the temperature decreases, cold urticaria also enters a high incidence period.
It is reported that cold urticaria is a type of physical urticaria that can occur in both adults and children. Unlike urticaria, cold urticaria has a relatively clear history of exposure to cold substances. Its typical feature is the appearance of itching erythema and wind masses in the affected area after skin contact with cold water, cold air, and other cold substances. Although most patients can resolve on their own, there are also some patients who may trigger severe systemic allergic reactions, such as throat swelling, chest tightness, abdominal pain and diarrhea, and should seek medical attention in a timely manner.
Elderly people should be alert to herpes zoster
It should be noted that the elderly are also a high-risk group for skin problems.
Yu Debao explained that as elderly people age, various physiological structures gradually change, and the protective and regulatory ability of the skin also decreases. The amount of oil and water that nourishes the skin decreases, making the skin dry and sensitive. The skin barrier function is damaged, the skin thickness becomes thinner, the elasticity is significantly reduced, and the ability to adapt to environmental stimuli is also decreasing. If encountering external stimuli, it is easy to develop skin problems.
Senile skin pruritus is more common in the autumn and winter seasons. Foreign epidemiological studies show that the incidence rate of skin pruritus in outpatients aged over 65 years is 12%, and the incidence rate of pruritus in outpatients aged over 85 years is 20%, which is related to skin aging and sebaceous gland dysfunction of middle-aged and elderly people.
In addition to the issue of dryness, the decrease in human immune function caused by seasonal changes can also increase the risk of viral skin diseases.
Herpes zoster is a viral skin disease that occurs frequently in autumn and winter. It is an infectious skin disease caused by reactivation of chickenpox zoster virus that has been dormant in the posterior root ganglia or cranial ganglia of the spinal cord for a long time.
Up to 90% of adults have chickenpox and herpes zoster virus latent in their bodies, and when the human immune system is relatively strong, the virus appears in a latent state; However, when immunity decreases, the virus is likely to be activated and replicated in the body, resulting in neuroinflammation and clustered blisters on the skin, accompanied by varying degrees of pain.
The incidence rate of herpes zoster is relatively high among the middle-aged and elderly people aged 50 years and above. Many patients are accompanied by chronic diseases, such as diabetes, chronic obstructive pulmonary disease, etc. Patients with immune diseases and other immune dysfunction also belong to the high-risk population of herpes zoster.
Yu Debao reminds that suffering from herpes zoster often has a dual effect and can lead to serious and long-lasting complications. The most common is post herpetic neuralgia, which can last for months or even years if no intervention measures are taken in the early stages of the disease.
Research has shown that the incidence of herpes zoster over the age of 50 may be associated with a higher risk of post herpetic neuralgia.
Care for skin, pay attention to preventing dryness and moisturizing
Yu Debao pointed out that most skin diseases in the autumn and winter seasons are related to dry skin and damaged skin barrier function. Therefore, to prevent skin diseases, it is necessary to strengthen skin care in daily life.
Due to the presence of a natural protective oil film on the surface of the human skin, the climate in autumn and winter is dry. Therefore, it is not advisable to clean the skin too frequently, for too long, and for the water temperature to be too high to avoid damaging the oil film and skin barrier. At the same time, use mild and non irritating washing products to reduce the use of alkaline cleaning products. Try to avoid over cleaning the skin. Immediately after bathing, apply moisturizing lotion or cream, such as products containing urea, glycerin or hyaluronic acid, and drink plenty of water to keep moisture inside the body.
In daily life, pay attention to maintaining a stable body temperature, maintaining a good and happy mood, ensuring sufficient sleep, and regular sleep and rest. In terms of diet, you can choose to eat more fruits and vegetables such as grapes, bananas, apples, carrots, and cabbage, and timely supplement the skin with vitamins and sugar. Pay attention to a balanced diet, and try to drink less strong tea and coffee. Humidifiers can be used indoors to increase air humidity and avoid prolonged exposure to dry environments.
When skin itching occurs, it is important to avoid excessive scratching as much as possible to avoid further damage to the skin barrier. If it's really unbearable, you can gently pat the itchy area or wipe with a special ointment. Choose loose, soft, and breathable pure cotton clothing and bed sheets, and avoid using products such as synthetic fibers and wool to reduce skin irritation. In addition, skin problems may also be the manifestation of internal diseases, such as diabetes, hepatobiliary diseases, thyroid diseases, and even malignant tumors.
Therefore, when encountering skin diseases, do not blindly apply ointment on your own. It is still recommended to seek medical attention in a timely manner, especially if the skin is dry and itchy, or the problem lasts for a long time, accompanied by other symptoms, further examination and treatment are needed to avoid delaying the condition.
