Recently, cold air has been "online" again, and strong winds have been ushered in everywhere. How can we prevent risks?

A cold air is moving eastward and southward, accompanied by strong winds. How to guard against risks?

Residents in southern China are prone to frostbite and even freeze to death due to lack of warm-keeping measures. They should pay attention to the weather forecast, buy clothes and warm-keeping products in time, and relevant institutions should also publicize health protection knowledge. Although residents in the northern region have relevant warm-keeping facilities, the temperature drops suddenly when the cold wave comes, so we should further strengthen the warm-keeping protection to prevent carbon monoxide poisoning. Residents in extremely cold areas should pay attention to the weather forecast, keep warm indoors and by themselves, prevent carbon monoxide poisoning, reserve enough warm items and food in advance, and try not to go out.

First: masks are added to keep warm and prevent diseases. The nose and mouth are the gateway to the respiratory tract. Mask is an indispensable cold-proof tool, which can effectively prevent dust and floating dust from invading the skin and also prevent the skin from being hurt by cold wind.

Second: Wash your face with warm water and drink more hot water. Wash your face at 20-37℃ and choose skin care products with good moisturizing effect. Drink more hot water, the amount of water you drink every day varies from person to person, but "drink more hot water" is by no means a perfunctory thing when it is cold.

Third: wear knee pads to protect joints. Many people will feel joint pain in windy weather. Especially when traveling by bike, you may wish to wear knee pads and wrist pads to protect your joints.

Fourth: open the window for ventilation and adjust the temperature difference. Excessive temperature difference between indoor and outdoor can also lead to high incidence of diseases. According to the air outside, you can open the window for ventilation twice a day for about 30 minutes each time.

Fifth: If a foreign object enters your eyes, don't blink. Windy weather can easily lead to foreign bodies entering the eyes. It is suggested to blink more to promote the secretion and discharge of tears, and avoid scratching the cornea by hard friction or embedding foreign bodies into the cornea, causing infection and inflammation.

Sixth: cardiovascular disease, try to go out as little as possible. The sudden drop of temperature is easy to induce diseases such as stroke, cerebral infarction and myocardial infarction. In addition to keeping warm, patients with cardiovascular and cerebrovascular diseases should try not to go out in windy days. If they have to go out, it is best to take some quick-acting pills, nitroglycerin and other drugs after 10.

Seventh: dress moderately and enhance immunity. Under the premise of ensuring that the body is not cold, it is not appropriate to cover it too tightly. Sweating will reduce immunity.

Cold weather (cold wave) will have a certain impact on human health, especially for the elderly, pregnant women, infants and vulnerable people such as cardiovascular and cerebrovascular diseases and respiratory diseases. However, these vulnerable groups have a low awareness of the cold wave risk and a weak sense of self-protection. Before or during the cold wave, it is necessary to strengthen the popular science propaganda on the cold wave risk of vulnerable people and improve their self-protection awareness. For example, pay attention to the early warning before the cold wave comes, and pay attention to strengthening indoor and self-preservation according to the temperature change. Residents feel unwell during the arrival of cold air, especially the elderly, pregnant women, infants, patients with cardiovascular and cerebrovascular diseases, patients with respiratory diseases and other vulnerable groups. They should go to the hospital in time. If you have any questions about public health and health, you can call the public health hotline 12320.
