On a cold winter day, Uncle Zhang was snapping up New Year's Day discounted goods at the community supermarket.
Just as he was picking out a down jacket and gloves, he suddenly heard someone call him: "Uncle Zhang, are you also here to buy winter supplies?" He looked up and saw that it was an old friend he hadn't seen for many years, Dr. Zhou, a dermatologist.
"Doctor Zhou, long time no see!" Uncle Zhang greeted happily.
The two chatted as they walked. Uncle Zhang mentioned that he was plagued by chilblains every winter, and Dr. Zhou began to introduce him to prevention and maintenance methods.
Dr. Zhou said: "Uncle Zhang, in fact, it is not difficult to prevent chilblains, the key is to pay attention to warmth and blood circulation. ”
Uncle Zhang listened attentively, and Dr. Zhou continued to explain: "First of all, keeping your hands and feet warm is the key.
In cold weather, wear warm gloves and socks to avoid direct exposure of your hands and feet to cold air.
Secondly, pay attention to the breathability of clothing, although overly sealed clothing is warm, it is easy to make the skin moist and hot, increasing the risk of chilblains. ”
Uncle Zhang nodded in understanding, and Dr. Zhou added, "In addition, proper exercise can help promote blood circulation and reduce the occurrence of chilblains.
Simple hand and foot movements, such as turning the ankles and wrists, can help improve peripheral circulation. ”
"Also, diet is important. "Moderate consumption of foods that promote blood circulation, such as ginger, garlic and chili, can also prevent chilblains."
But be careful not to overdo it so as not to irritate the skin. ”
After hearing this, Uncle Zhang felt that he had benefited a lot, and decided to follow these methods for prevention and maintenance when he returned home.
epilogue
Just as the story was about to end, Dr. Zhou asked a seemingly unrelated question: "Uncle Zhang, do you know why it is easy to cause vasoconstriction in winter?"
This is actually because the cold environment stimulates the body's sympathetic nervous system, causing blood vessels to constrict to reduce heat loss.
This vasoconstriction reaction is more pronounced in some people, triggering chilblains.
Therefore, proper measures to keep warm and promote blood circulation can not only prevent chilblains, but also improve the overall physical condition in winter.
