**Itching** is one of the most common **diseases, especially some severe**itching, itching is unbearable, affecting sleep and normal life. Some people can't help but choose to use hot water to scald, but the result is not only not better, but more and more itchy; Some people keep scratching, causing ** to be scratched and causing infection; Some people will choose to use sulfur soap to clean, or go to some informal clinics to buy so-called "ancestral" ointment and apply it at once, and end up spending a lot of money ......
In fact, none of these methods are scientifically effective.
So what exactly is the cause of itching?
At the end of the day, there are only three causes of itching: allergies, dryness, and itching caused by systemic diseases.
1. **Allergies.
Allergies are normal and are one of the most common causes of itching. Like food allergies, cosmetics allergies, drug allergies, physical allergies, etc., in daily life, can cause itching.
Itching caused by allergies is a **reactive** disease, like the most common** diseases such as atopic dermatitis, eczema, urticaria, atopic dermatitis, drug allergies, etc.
For the **itching of this condition, most of them will get better quickly after getting rid of the allergen and carrying out targeted anti-allergic**.
2. **Drying.
There are many people who will have questions: Does dryness also cause itching? In fact, not only will, but a lot of itching is due to dryness.
Due to the dry climate and cold winter, the sebaceous glands will slowly degenerate, often making the lipid film on the surface of the middle-aged and elderly people thinner, and the moisturizing ability is greatly reduced, and the dryness and desquamation are dry, and itching occurs, especially in the lower limbs. Such as ** pruritus, lipo-deficient dermatitis, etc.
For the dryness caused by this reason, you can choose to apply more lubricating and moisturizing skin care products, keep the air relatively moist, drink more water, pay attention to water retention, and avoid dehydration.
3. Systemic diseases.
*Itching can also be a manifestation of some systemic diseases, such as **itching due to uremia, jaundice and **itching due to abnormal liver function, and **itching due to some malignant tumors.
These types of itching, anti-allergic or moisturizing cannot be relieved and can only be relieved by carrying out systemic diseases after being identified.
How to avoid itching?
In view of the three types of itching, we can put forward five preventive measures:
1. Take a bath scientifically.
Many people think that itching is dirty and need to take a bath. As everyone knows, it is precisely because of this idea that the number of baths has increased, and the wrong use of alkaline soap has further aggravated the itching.
In order to avoid itching, you can reduce the frequency of bathing, choose the appropriate bath water temperature, and do not choose soap that is too alkaline. At the same time, be careful not to rub too much, and use a suitable bath towel.
It is scientifically recommended to rinse with warm water (close to body temperature) 1-2 times a week, without using or using a mild bath, and apply a thin layer of oily moisturizer to the whole body or itchy area after bathing. Improper bathing will destroy the original protective layer of sebum film, making ** more dry and itching aggravated.
2. Apply and use emollient moisturizers appropriately.
In some areas or specific seasons, the dry climate is very easy to lead to dryness, and these people should pay more attention to the use of moisturizers, so as to keep moisturizing and avoid dryness.
3. The living environment should be comfortable.
The most comfortable living environment for the human body is about 20-25 degrees Celsius, and it should not be too cold or too hot. It can avoid the aggravation of **disease due to overtemperature and excessive evaporation of sweat to reduce ** water content, because ** dryness and high outside temperature will aggravate **itching.
4. Seek medical attention in time to find out the cause.
If the itching does not improve, it is necessary to seek medical attention in time to find out the cause, if it is caused by a systemic disease, it is necessary to promptly ** systemic disease, and at the same time, under the guidance of a doctor, use anti-itch drugs in a timely and correct manner.
5. Avoid excessive scratching.
Excessive scratching can only temporarily obtain comfort, but once it causes **to be scratched, it can easily lead to **infection, further aggravating the condition.
The correct way is to scientifically use internal and external anti-itch drugs under the guidance of a doctor to avoid ** stimulation caused by constant scratching and aggravation of itching.
