A sharp drop in temperature is about to begin, experts remind:
These parts that are not resistant to frost should focus on keeping warm
On November 28, the Central Meteorological Observatory continued to issue an orange warning with the highest level of cold wave.
It is expected that by December 1, there will be severe cooling in some areas in the central and eastern regions of my country, and it is essential to do a good job in preventing cold and keeping warm.
So which parts should we focus on for protection?
And who are the "key protection objects"?
The reporter consulted experts from Nanjing Hospital of Integrated Traditional Chinese and Western Medicine.
These 6 parts of the body are the least resistant to "freeze"
When it comes to the parts of the human body that are least resistant to "freezing", the head, neck, back, navel, knee joints, and feet are definitely on the list, and they need to focus on keeping warm.
Why?
Xia Gongxu, a well-known doctor of traditional Chinese medicine in Nanjing and deputy director of the prevention and treatment department of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, explained that the feet are farthest from the heart and have less blood supply, and because the fat layer of the feet is thinner, they are particularly vulnerable to cold stimulation. .
Cold feet are especially likely to cause capillary contraction of the upper respiratory tract mucosa, resulting in a decline in the body's resistance.
"The head is also one of the parts that are not good at retaining heat, so we must pay attention to keeping warm." Xia Gongxu said that keeping the neck warm is often ignored at this time. Chinese medicine believes that the back is connected to the viscera. The ability to be cold will be greatly reduced, and more sun exposure is required.
Cold in the navel can easily cause gastrointestinal dysfunction, and digestive system diseases such as abdominal pain and diarrhea may occur.
In addition, the knee joint is not protected by rich fat and muscle, and is very sensitive to temperature and humidity. The knee joint is prone to degenerative changes when exposed to cold, and problems such as pain and difficulty in flexion and extension occur.
Three groups of people should pay special attention to protection
Yang Runhua, director of the emergency department of the hospital, said that the onset of myocardial infarction has a certain relationship with the sudden drop in temperature.
Generally, when the temperature drops by 3 to 5 degrees Celsius or more, the incidence of acute myocardial infarction will also increase.
Xing Junwu, director of the Cardiovascular Department of the hospital, said that among young patients with acute myocardial infarction, at least one or more risk factors such as smoking, high blood pressure, diabetes, and obesity account for one or more.
The three types of people below the sudden drop in temperature should pay special attention to protection, and go to the hospital in time if they feel unwell.
The first category: patients with a history of high blood pressure, diabetes, and hyperlipidemia, especially those who have been clearly diagnosed with coronary heart disease; Alcohol history, people with high work pressure, often staying up late, and inactive people.
At the same time, experts suggest that due to the cold and dry climate in autumn and winter, we should pay attention to moderate water intake.
