It turns out that the climate in autumn and winter is cold, and sebaceous gland secretions are difficult to discharge to the body surface. Scientific tests show that the melting point of fat secreted by human sebaceous glands is about 30 degrees Celsius. In the cold season, skin fat is almost solidified into a solid state, which is more difficult to discharge, which makes people's skin dry more obviously in winter. Especially for the elderly, with the increase of age, the metabolic function gradually declines. Because of the decrease of endocrine and the disorder of sebaceous gland secretion, the skin will be dry and itchy. Moreover, the activity function of skin sweat glands is obviously lower than that of young adults, and the amount of perspiration is reduced, which makes the skin surface lack of moisture, which is of course drier and more itchy in dry winter.
Mr. Ma, a famous crosstalk artist, once said that a crosstalk was called "The Secret Recipe of the Ancestral Family", which was widely circulated. He said that someone was itchy and spent a lot of money on an ancestral secret recipe. The medicine is wrapped in layers and tightly wrapped. After tearing this layer, tear off three layers and remove four layers. On the last floor, a small piece of paper was exposed, on which only two words were written: scratch.
What about itching? Scratch! This seems to be a universal natural answer.
When people itch, their hands stop. Even in the corner where their fingers can't reach, there is an arm (the old man is very happy) to rescue them in time. After these "noises", the troubles receded and I felt comfortable all over. However, scratching a few times when itching can solve the problem quickly, but scratching often, especially scratching with itching, lays a curse for itchy skin. But since the water is still flowing, although we cut it with our swords and raise our glasses to drown our sorrows.
Tracing back to the source, itching is an abnormal feeling caused by chemicals, bacteria, parasites, abnormal metabolites, skin inflammation, chemical fiber fabrics and other factors that stimulate nerve receptors in the skin. Moreover, both itching and pain are produced by the same peripheral nerve receptor located in the dermal papilla, just because the severity of stimulation is different, ranging from itching to pain.
You can't scratch your skin too much if it itches.
Scratching with hands, especially tickling, actually enhances the stimulation to the skin and makes the skin painful, thus covering up the itching feeling. With the passage of time, the skin surface will undergo proliferative changes. Roughness and hypertrophy of skin itself is the stimulation of peripheral nerve receptors, which will aggravate itching and form new conditioned reflex. The result is that the more you scratch, the more you itch, causing a vicious circle.
Some people will have a hot bath and a nice perm to relieve itching. However, the end result is often that the hotter the itch. This is because taking a hot bath, due to frequent burns and soaping, will make people's epidermis lose the already insufficient fat film, and even the normal moisture content of the skin surface is difficult to maintain, so it will be more itchy. It seems that this way of relieving itching is not enough.
First of all, we should pay attention to strengthening physical fitness and exercising properly. Massage the whole body before and after undressing in the morning and evening to promote skin microcirculation and reduce skin dryness.
Secondly, good living habits such as maintaining personal hygiene, changing underwear frequently (underwear is preferably soft cotton and silk) and eating less irritating food can effectively prevent itching. Use warm water bath instead of hot water bath, 1 ~ 2 times a week, and avoid using strong alkaline laundry soap, use neutral soap or bath liquid, and the dosage should be appropriate, and do not rub for a long time.
Teach you three ways to relieve itching
When local skin itches, fresh towel gourd leaves can be pounded and applied to the affected area, and the treatment effect is better.
When the skin is itchy, you can put a pinch of cigarette ash into a container, drop a few drops of water to make it paste, and apply it to the affected area to stop itching.
Acute localized dermatitis or itchy skin can be relieved by washing and smearing with salt water.
At the same time, you should know some health guidelines for itching.
First, pay attention to reasonable skin care, clothes should be wide and soft, don't wear wool, underwear should be cotton or silk. When taking a bath, you should reduce irritation, do not use too alkaline soap or too much friction, and try to avoid scratches. The bath water temperature should be 35 ~ 37℃. Bedding should not be too warm. Apply proper amount of lubricating oil ointment to protect the skin in winter.
2. Avoid anger and impatience. Usually, you can choose to take a walk, play badminton, Tai Ji Chuan, practice Qigong and other activities. Cultivate good habits such as raising flowers, goldfish and playing chess to cultivate sentiment, get up early and go to bed early, don't watch exciting film and television programs, and don't drink strong tea and coffee before going to bed to ensure adequate sleep.
3. Don't eat allergic or irritating food, such as fish, shrimp and crab. You should give up smoking and drinking, and don't drink strong tea or coffee. The diet should be light and digestible, and eat more fresh fruits and vegetables. Smooth stool can effectively and timely expel allergens accumulated in the body. Foods that have been proved to be allergic, including similar foods, are absolutely to be avoided.
4. Actively prevent and treat primary diseases, such as diabetes, jaundice, intestinal parasitic diseases, etc., in order to eliminate the causes of aggravating the disease.
