The "diving" cooling is coming! Doctors remind you to protect these 5 parts of your body!

Some time ago, the temperature soared in many places, making people feel that summer had arrived instantly, and some places were even warmer than June.

However, surprisingly, the temperature dropped sharply just a few days after the temperature rose. According to China Weather Network, the cold air will continue to affect the northern region in the next few days, and the temperature in most areas will begin to drop. The previous warming trend has been curbed, and the temperature in some areas has dropped by more than 20℃.

Middle-aged and elderly people are easily affected or may develop health problems due to a sudden drop in temperature, so please be careful.

Sudden drop in temperature

These 5 parts of the body are most affected

1. Blood vessels: Hot and cold weather can cause strong vasoconstriction

Zhao Xinjun, deputy chief physician of the Department of Cardiology at the First Affiliated Hospital of Guangzhou University of Chinese Medicine, introduced that the temperature in spring is alternating between hot and cold, and the human body's blood pressure, heart rate, and cardiovascular system will also respond to stress and adjust accordingly. Some plaques on the vascular endothelium become very unstable and easily ruptured, and blood clots are formed.

2. Respiratory tract: protective function may be reduced

Zhou Hui, chief physician of the Department of Respiratory and Critical Care Medicine at the Affiliated Hospital of Chengdu University, said that the mucous membrane on the surface of the respiratory tract has a defensive ability, but in winter and spring, due to the cold weather and the stimulation of cold air, its defensive function is reduced, and the pathogens in the air can easily invade from the respiratory tract. The climate changes greatly with the seasons, especially during the transition from late autumn to early winter, when the temperature changes greatly between morning and evening and at noon, and the temperature difference between indoors and outdoors is also significant, making it easy to catch a cold. When you catch a cold, your body's resistance is reduced, and it is easy for pathogens to invade the body.

3. Knee joint: Some people may experience joint pain

Sha Yu, chief physician of the orthopedics department of the Third People's Hospital of Henan Province, introduced that if healthy people and arthritis patients are exposed to the same cold environment where the temperature drops from 30℃ to 15℃ in a short period of time, arthritis patients may experience joint pain, while healthy people may not have obvious reactions.

This is because the peripheral blood vessels of patients with knee arthritis have prolonged contraction and expansion time, and they often experience joint pain when the weather suddenly turns cold. At the same time, cold weather can also increase the viscosity of the synovial fluid in the knee joint, which increases resistance when the joint moves.

4. Stomach: prone to cramps and discomfort after catching a cold

Fu Zhiquan, chief physician of the Department of Gastroenterology at the Shanghai Hospital of Integrated Traditional Chinese and Western Medicine, pointed out that gastric and duodenal ulcers are seasonal, with autumn and winter and winter and spring being the peak periods.

Yu Bin, director of the Department of Gastroenterology at the First Affiliated Hospital of Hunan University of Chinese Medicine, said that when the body is stimulated by cold, the secretion of histamine increases, which in turn promotes the secretion of a large amount of gastric acid, which can easily cause uncomfortable symptoms such as stomach burning and stomach cramps.

5. Neck: Neck muscles tend to become stiff due to cold

A cold neck will make the neck muscles tense and stiff, which is an important factor in the onset of cervical spondylosis. The neck includes the cervical vertebrae, arteries, respiratory tract, esophagus, etc. If any of them is cold, people will feel uncomfortable. If you feel cold, you might as well wrap yourself in a small gauze scarf.

4 small details

Help you protect your health

1. Try the onion dressing method

It is recommended to wear thicker clothes on the bottom and thinner clothes on the top. Generally speaking, when the temperature remains above 15℃ and is relatively stable, some thick clothes can be taken off. However, for special groups such as the elderly, patients with cardiovascular and cerebrovascular diseases, and patients with rheumatism, it is recommended not to take off too many clothes too early. Even if you feel a little hot or sweat a little, do not take off too many clothes immediately.

When you go out, you can wear an autumn coat, a thin sweater or sweater on the outside, and a coat. This way you can add or remove clothes according to the weather conditions.

2. Open windows for ventilation twice during the day

Close doors and windows at night to prevent wind and cold; open windows for ventilation during the day to keep the indoor air fresh and sunny, and prevent the growth of pathogenic microorganisms such as bacteria and viruses.

3. Don’t wait until you are thirsty to drink water in spring

Spring is dry, so drinking enough water to keep the respiratory tract moist can help improve the natural defense function of the respiratory tract.

4. Exercise in the afternoon when the temperature warms up

Elderly people with poor physical fitness are advised to exercise in the afternoon when the temperature rises. When choosing sports, it is best to choose sports that do not require much exercise, such as Tai Chi, jogging, mountain climbing, and walking.
