Seasonal pruritus refers to pruritus caused simply by dry weather and other causes. It is common in elderly and mainly occurs on upper extremities, anterior part of lower leg, and lower back. With such itching, opinions of dermatologists are as follows: “Itchy skin caused by other diseases should be treated in accordance with underlying disease. It is best to change medicine for itchy skin caused by medicines. As for seasonal skin itching, it should be on skin nutrition. "So, in cold and dry autumn and winter, there are principles of skin nutrition:
Principle 1. Reduce sebum loss and replenish sebum reserves in a timely manner
Southerners often take baths, especially hot baths, which wash away too much fat from body and increase dryness of skin. Doctors advise that temperature of bathing water be 32°C, and time should not exceed 15 minutes, do not take a bath and do not use shower gel every day. After bathing, apply moisturizer all over your body while skin is still damp, and apply a thicker moisturizer to hands, feet, knees, and joints.
Principle 2: A Scientific and Smart Diet
To prevent drying of skin, drink plenty of water, eat more vegetables, fruits and soy products to reduce water loss in body. At same time, pay attention to consumption of foods high in iron, such as animal liver, egg yolk, algae, foods rich in B vitamins such as vegetables such as carrots, and foods rich in colloids such as trotters and pork leather. Eat less spicy foods such as coffee, strong tea, chili peppers, onions, garlic, or acidic foods that will aggravate itchy symptoms.
Principle 3: Finally, choose loose-fitting pure cotton clothing for underwear
Wearing is also important to protect skin. First, wear pure cotton clothing (especially underwear), and do not wear chemical fiber or knitwear, as latter easily cause static electricity and itching; secondly, clothing should be worn loose and not tight to body. . Cha Xiushan also emphasized need to wear long clothes so that skin does not dry out with direct blowing.
In addition to nutrition, we should also pay attention to fact that if you bathe too often in autumn and winter and use a large amount of bath liquid, this will cause excessive loss of normal keratinocytes and further thinning of sebum. membranes, resulting in damage to skin barrier, thus causing dry, itchy skin.
It can be seen that although bathing is a personal hygiene habit, there are also many taboos. When bathing, you should pay attention to four main undesirable phenomena:
1. Bathing time should not be too long, about 10 minutes is enough
Many people fear they won't be clean every time they take a bath, especially some women who are obsessed with cleaning: too much, skin without sebum protection will feel dry and flaky and then itchy.
Second, can not be washed with hot water, water temperature is 40℃.
Thermal stimulation can suppress itching, so most itchy patients like to "scald" hot water, and some older people even use salt or pepper water to scald. At same time, I felt very "comfortable" and "itching was removed", but I do not know that temperature of overheated water is a bad irritant for skin, it dissolves protective film on surface of skin, makes skin drier, and itching intensifies more easily. Optimal temperature water 40°C.
Third, bathing should not be too frequent
Since sebum membrane is very important to protect skin, and skin of elderly is very dry due to aging, it is sufficient for elderly to take a bath once a week. And some people, who are more picky and have a habit of bathing every day, may take a bath every day, but not wash every time "thoroughly". around your body every time you take a bath, parts are "seriously" cleaned. Excessive use of these cleansers will inevitably remove sebum film of skin itself in winter so that it is more “clean”. Unprotected skin with a film of sebum naturally dries and itches. Therefore, every time you take a bath, you can wash your neck, armpits and genitals with bath liquid, but not too much, you can just shower with warm water for other parts of body. alkaline soap.
Fourthly, it is not recommended to rub hard
Many young people enjoy going to sauna and vigorously rubbing their hands until their body turns red. In fact, "dirt" that separates from rubbing is a protective film of skin. This is because in metabolism of epidermis, keratinocytes will be constantly lost. After soaking in water, water content of stratum corneum will increase and become loose. At this time, after strong friction, it will become what people often call "dirt". Frequent soaking in hot water and scrubbing can lead to excessive secretion of normal keratinocytes and thinning of sebum, causing excessive damage to skin barrier's protective function. The skin will also become more itchy after "dirt" is washed off. Excessive scrubbing is one of most important causes of itchy skin. For some people with dry skin, especially elderly, after taking a bath, it is best to apply moisturizers with a skin moisturizing function for 5 minutes on body and keep skin moist with an external “moisturizing factor”. dryness and flaking of skin, reduce occurrence of itching.
In addition, it is best to change your underwear in time after each bath. Underwear should be loose, soft and comfortable. Try to wear soft cotton underwear. body to avoid skin irritation. Once itching occurs, it can be relieved by patting or rubbing with pulp of your fingers, and try to avoid scratching with sharp nails because scratching can make local sensory nerves more agitated and sensitive due to repeated stimulation, further aggravating itching. thus forming a vicious cycle of more itching and scratching, more scratching and itching. Itching is more common in winter, so you can also carry some anti-itch ointments containing camphor, mint, and borneol.
