The wave of the autumn allergy season has just passed, and it has ushered in the peak of dryness and itching in winter. When the symptoms are severe, the affected area is like an ant crawling, and there is a significant burning sensation, which makes it difficult for the patient to sleep at night and unable to concentrate during the day. So, how can we effectively resist the invasion of this "flood peak"?
1. What is itching?
Winter pruritus is also known as sebum-deficient eczema, eczema craquele, and winter eczema. Eczema-like dermatitis with a prominent dryness and splitting occurs in the elderly**, especially in the lower legs, forearms, and hands, and the main cause may be sebum deficiency and water loss in the middle**.
There are many factors that cause sebum deficiency, including natural dryness with obvious sebum deficiency, age (elderly), disease, malnutrition, atrophy, sclerosis, lack of sweating, endocrine dysfunction, environmental humidity, and destruction of the integrity of corneal moisture storage.
2. What is the reason for "itching"?
In winter, it is dry, and the resistance to external stimuli is reduced, which is easy to cause itching.
In winter, the bath water is overheated, which is easy to take away the sebum on the sebum, and if it loses the protection of the sebum film, it is easy to have symptoms such as dryness and itching.
Extreme diets and picky eating lead to nutrient deficiencies, loss of moisture and elasticity, and dry and fragile skin, which can cause pruritus.
3. Misunderstanding: "scratching, scratching" and "taking more hot baths" to solve itching?
Scratching will only create a vicious cycle. Scratching** damages keratinocytes, producing an inflammatory response and a variety of transmitters, which further stimulates nerve fibers and causes itching in the sensory nerve centers of the cerebral cortex. Excessive scratching and rubbing can also destroy the barrier of **.
In winter, the secretion of human sweat glands decreases, if the bath is too frequent and the water temperature is too hot, it is easy to take away the sebum on the body, and if the protection of the sebum film is lost, symptoms such as dryness and itching will appear. At the same time, you should also use less soap, shower gel and other detergents to reduce the irritation of **.
Therefore, scratching and taking a hot bath can only relieve the itch for a while, and the key is to reduce the itching from the root.
Fourth, winter scientific prevention** "dryness, itching" strategy, please put away.
It is not necessary to bathe every day: it should be adjusted appropriately according to the intensity of physical activity, the degree of sweating and personal habits. Under normal circumstances, take a bath once every 2-3 days, especially for middle-aged and elderly people, the water temperature of the bath is about 37-42 degrees Celsius, and the bathing time should not be too long, preferably about 15 minutes.
Gentle cleansing: Use gentle cleansers and body washes, and avoid washing products that contain harsh chemicals. After bathing, gently pat dry** and avoid excessive rubbing.
Apply a moisturizer after bathing: Choose a lotion rich in moisturizing ingredients, a cream, or a body lotion and apply it to the washed **. Pay special attention to areas prone to dryness, such as hands, feet, and knees, and apply moisturizer to relieve symptoms such as chapped and itching.
Wear cotton underwear: choose soft, breathable clothing and avoid wearing rough fabrics to reduce friction and irritation to prevent further spread of itching.
Diet: Avoid allergenic foods such as fish, shrimp and crab, and do not eat spicy and irritating foods such as chili peppers and peppercorns. It is forbidden to drink alcohol, drink less coffee and strong tea, and eat sesame seeds, fungus, yams, okra and other foods that help nourish yin and moisturize dryness. Drinking plenty of water, eating more vegetables and fruits, eating a balanced diet, and consuming foods rich in vitamins and antioxidants can help maintain a healthy state.
