Studies have shown that itching is a more unbearable feeling than pain. Sometimes the itch can last for a few hours, making people uncomfortable and even sleepless. When the "annoying itch" is frequently visited, it is just a wake-up call for health.
70% of adults and 90% of the elderly suffer from skin itching
According to the survey, there are more than seven adults with unexplained skin itching in their lives, among which the skin itch of the elderly is as high as 90%; six adults said that “it will not be taken care of if the itch is not strongâ€, and three adults will “make their own thoughtsâ€. Ways to stop itching (such as the use of drugs), only one adult will find the cause after the skin itch, the young white-collar workers due to lifestyle habits, work stress, etc., the appearance of skin problems is obviously rising; children can not correctly express Itchy skin is hard to find the cause.
Yang Shuxia, deputy director of the Department of Dermatology, Peking University First Hospital, said that since the beginning of winter, patients who came to the hospital because of itchy skin have been in constant stream. “Some patients can't help but itch and continue to scratch, and there are secondary damages such as scratches, blood stasis, and pigmentation on the skin. Some patients use hormones in thin skin such as the face, armpits, and thighs. Drugs that cause skin atrophy, telangiectasia, and secondary infections."
According to a World Health Organization survey, among the yellow races, less than 10% of the skin is in a healthy state, more than 20% are in a morbid state, and 70% are in a sub-healthy state. Itching is the first feeling that 80% of patients with dermatology describe when they express their feelings. "After all, it’s a small part of coming to the hospital to seek medical help. Many people still choose to endure, or they don’t take it seriously." Yang Shuxia said.
Emotional stress, liver disease, and diabetes are common causes of itching
Glenn Gisler, a professor of neuroscience at the University of Minnesota, said that after studying the topic of itching for decades, we found that there are at least 50 reasons why people feel itchy. The most important ones can be summarized as follows. several aspects:
Simple skin problems. "There are two cases of itching due to the skin's own problems," Glenn Gisler said. One is that there is no primary skin damage, mostly due to lack of moisture in the skin. Just like in the dry winter, many people feel that the skin is itchy and peeling. The other is that the skin itself is "ill", and skin diseases such as dermatitis, eczema, and psoriasis are mostly accompanied by itching.
Middle and old aged skin is degraded. In the middle-aged and elderly people, because the skin shrinks and shrinks, the water content decreases, the secretion of sebaceous glands and sweat glands decreases, and the skin loses its lubricious protective effect and appears dry. In the cold season, the dry climate makes the skin rough and even the epidermis sheds, making the inner nerve endings more susceptible to irritation and itching. This is the reason why the elderly have more itchy skin.
allergy. Professor Liu Guanghui, chief physician of the Department of Allergy, Wuhan Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, said: "One-third of patients who come to the clinical department of allergology have symptoms of itchy skin." Allergic to diet, pollen, dust mites, etc. Certain chemicals can cause allergies and make the skin feel itchy. This type of itching usually improves after stopping contact with allergens.
Gynecological inflammation. If women find itching in the genital area, they should check for gynecological inflammation such as trichomoniasis and Candida albicans infection. According to the survey, 73% of women feel local itching during menstruation, which may be related to poor quality sanitary napkins or too tight clothing.
Emotional tension. Depressive, nervous, irritated and other negative emotions may cause local or general skin itching. B vitamin deficiency is also easy to cause itchy skin.
Hepatobiliary disease. Hu Liming, deputy director of the Department of Gastroenterology, Oriental Hospital, Beijing University of Chinese Medicine, said: "Many systemic diseases can also cause itchy skin." Studies have shown that about 40% to 60% of patients with hepatobiliary disease, liver discomfort, liver Abnormalities and pruritus can occur when jaundice occurs.
diabetes. The incidence of skin itching in diabetic patients is as high as 15% to 35%. About 10% of early patients will have systemic or localized skin itching, and it is more stubborn, with the most serious vulvar or anal symptoms.
Thyroid dysfunction. Whether it is hyperthyroidism or hypothyroidism, skin itching may occur, but the itching caused by hyperthyroidism develops more slowly, the skin is more dry, and it will increase in winter.
Malignant tumor. Some tumors are accompanied by itchy skin, such as the lymphatic system, stomach, intestines, liver, ovaries, and prostate cancer. The itching caused by the tumor is mostly stubborn. If your body has a long-term itching without cause, you need to pay attention.
Six strokes to relieve dry itching caused by lack of water
What should I do if I find itchy for unknown reasons? Professor Liu Guanghui said that it is first necessary to identify whether allergens have been exposed to allergens. Secondly, you should go to the dermatology department to rule out the problem of the skin itself and see if the skin itself is "ill". Finally, if it is caused by other diseases, it should be treated in time for the root of the disease.
"Before you understand the cause, be sure not to use too much alkaline soap for too much cleaning, and use hormonal drugs under the guidance of a doctor." Yang Shuxia stressed. In the autumn and winter seasons, people's itch is more caused by lack of moisture in the skin, especially in the elderly. If it is a slight itching, try these six tricks:
No need to take a shower every day. You don't have to take a bath every day in the autumn and winter, especially in the elderly. Bath water temperature can be around 40 °C, should not be too high. It can be washed every 5~10 minutes. It is best to choose a neutral and weakly acidic body wash, even without using a body wash.
Apply the lotion first and then dry the body. Applying a lotion without drying the skin after bath can make moisture and nutrients more fully absorbed.
Raise a tank of goldfish to replenish the room. Lower the heating a few degrees if the body allows it, use a humidifier or raise a tank of goldfish to replenish the room, which can reduce the itching caused by excessive temperature and dry air.
Choose pure cotton clothing. Soft, less irritating clothes can prevent further spread of itching, increase breathability, and cause no allergies when in contact with skin.
Overnight tea can effectively relieve itching. Wash your hair with a warm overnight tea or rub it, the fluorine contained in the tea can quickly relieve itching, and at the same time it can also prevent eczema.
Eat more food for lungs and fluids. Drink plenty of water in winter and eat more fruits, vegetables and soy products to reduce water loss in the body. You can also eat some foods such as pears, lilies, jujubes, lotus seeds, white fungus, etc., do not eat or eat spicy food. Foods rich in vitamins A and B should also be eaten. >>>7 whitening tips to teach you to quickly whiten
