What to do if your skin is itchy? How to prevent itchy skin?

:Many people have itchy skin in winter, so how should we deal with this situation? As soon as winter comes, many people feel unwell, and the dry air causes serious damage to human tissues. Many people suffer from itchy skin, especially when they take off their clothes before going to bed at night. They feel itchy from their arms to their legs. What is going on?

: It turns out that the cold climate in autumn and winter makes it difficult for sebaceous gland secretions to be discharged to the body surface. Scientific testing shows that the melting point of fat secreted by human sebaceous glands is about 10 degrees Celsius. In the cold season, skin fat almost solidifies, so it is more difficult to discharge, which makes people's skin dryness more obvious in winter. Especially for the elderly, their metabolic function gradually decreases with age. Due to the decrease in endocrine, the secretion of sebaceous glands is imbalanced, so the skin will be dry and itchy. Moreover, the activity of the skin's sweat glands is significantly reduced compared to that in young adults, and the amount of sweat discharge is reduced, leaving the skin surface lacking moisture. In winter when the air is relatively dry, the skin will of course be drier and more likely to itch.

(>: Remember not to scratch your skin if it is itchy

: Scratching it with your hands, especially with itch, actually strengthens the skin's irritation The stimulation causes pain in the skin, thus covering up the itching. Over time, the skin surface will undergo proliferative changes. The skin becoming rough and hypertrophic itself is a stimulus to the peripheral nerve receptors, which will aggravate the itching, forming A new conditioned reflex. The result is that the more you scratch, the more it itches, creating a vicious cycle. Some people will also have this experience. When they are itchy, they take a hot bath and apply a nice hot iron to relieve the itching. However, the final result is often The hotter it gets, the more itchy it becomes. This is because hot water baths, frequent scalding and scrubbing with soap will cause the original insufficient fat film on the human epidermis to be lost, and even the normal moisture content on the skin surface will be difficult to maintain, so It will become more itchy. It seems that this way of relieving itching is not advisable.
