The severe cold wave is coming! The temperature drops drastically. What should we pay attention to when eating, dressing and traveling?

With the arrival of the severe cold wave, the temperature drop will enter the main period, and the temperature in most parts of central and eastern China will hit a new low in the second half of the year. In particular, many places in the north will experience a large drop in temperature, accompanied by strong winds and obvious wind chill effects. At the same time, there will still be large-scale rain and snow in central and eastern China, and precipitation in the northeast and other places will develop more strongly.

The Central Meteorological Observatory continued to issue a yellow warning for cold waves at 10:00 on November 25:

It is expected that from 14:00 on November 25 to 08:00 on November 28, the temperature in most areas of central and eastern my country will drop by 6-10℃ successively, among which the temperature in northern North China, central Inner Mongolia and Northeast China will drop by 12-14℃, and above 16℃ in some areas. Around the 28th, the minimum temperature of 0℃ will be pushed south to the northern part of Jiangsu and Anhui and the southern part of Henan, among which the minimum temperature in high-altitude mountainous areas such as Dabie Mountain and Huangshan Mountain will also be below 0℃.

It is expected that from 14:00 on November 25 to 14:00 on November 27, the central and eastern Inner Mongolia, North China, central and southern Northeast China, Huanghuai, Jianghuai, eastern Jianghan, and northern Jiangnan areas will successively drop in temperature by 6 to 10°C. Among them, parts of central Inner Mongolia, northern North China, and central and southern Northeast China may drop in temperature by more than 12°C.

Rain and snow weather will further move eastwards, and some parts of Northeast China may experience heavy snowstorms tomorrow

As the cold wave moved southward and the warm and humid air flow converged, yesterday, a large area of ​​my country was hit by rain and snow, which was also the largest day of rain and snow in this process. Monitoring shows that light to moderate snow, sleet or rain turning into snow occurred in eastern Qinghai, Gansu, Ningxia, central and northern Shaanxi, central Inner Mongolia, Shanxi, northwestern Hebei and other places, and heavy to blizzards occurred in northeastern Qinghai and central and eastern Gansu. Moderate rain and local heavy rain occurred in parts of southern Shaanxi, southern Henan, Hubei, western Sichuan Basin, Chongqing, northeastern Guizhou, central and northern Hunan, southern Fujian, central and southern Guangdong and other places.

The Central Meteorological Observatory continued to issue a yellow snowstorm warning at 10:00 on November 25:

It is expected that from 14:00 on November 25 to 14:00 on November 26, there will be heavy to severe snow in northeastern Inner Mongolia and most of Northeast China, among which, there will be heavy snow (20-26 mm) in parts of northern Heilongjiang, northeastern Liaoning, southeastern Jilin, etc. The new snow depth in some of the above-mentioned areas will be 5-10 cm, and may reach more than 15 cm in some places.

Today and tomorrow, the rain and snow will further move eastward, and precipitation in the Northeast and other places will develop and strengthen. The Central Meteorological Observatory predicts that today, parts of central and eastern Inner Mongolia, northern Hebei, western and northern Beijing, and the Northeast will have light to moderate snow or sleet. Among them, parts of eastern Inner Mongolia, central and western Heilongjiang and northeastern Heilongjiang, western Jilin, and eastern Liaoning will have heavy to heavy snow or sleet. Parts of the eastern part of the Northeast, central and eastern North China, most of Huanghuai, Jianghuai, eastern Jianghan, Jiangnan, southeastern Southwest China, and South China will have light to moderate rain. Among them, parts of eastern Liaoning, southeastern coastal Guangdong, and southeastern Hainan Island will have heavy rain. Parts of northeastern Inner Mongolia, eastern Gansu, northern Hebei, and the Northeast will have winds of 4 to 6.

As the temperature drops sharply, we need to pay more attention to diet, clothing, travel and other aspects to ensure our health and safety.

Dressing: Keep warm and prevent sweating

Although the outdoor temperature is very low, keeping warm does not mean wearing as much as possible. In many places, indoor and public places have turned on heating to keep warm. Excessive warmth may cause excessive sweating, which not only consumes a lot of physical energy, but also may make people feel colder because the evaporation of sweat takes away the body's heat. In addition, being in a humid environment for a long time may also cause colds, rheumatism and other diseases. Therefore, in this living environment, it is recommended that everyone adopt the " onion dressing method ": wear more layers and add or remove clothes in time according to the environment.

For example, wear close-fitting underwear and loose and soft clothes in the middle. The wrists and ankles of outerwear should be closed to prevent heat loss. The head, neck, and feet are the most sensitive to cold , so hats, scarves, and warm shoes and socks can also be arranged; at the same time, match them with warm sweaters or fleece clothes, and then put on a jacket, coat, or down jacket on the outside, so that it is convenient to put on and take off according to the ambient temperature, ensuring that you will not be cold or sweat.

Take proper supplements and pay attention to water intake

In cold weather, the diet should be warm and nutritious to enhance the body's resistance and resist the cold; eat more foods containing vitamins, minerals, and dietary fiber to ensure a balanced diet. For patients with cardiovascular and cerebrovascular diseases , it is recommended to eat low-salt, low-fat, and low-sugar tonics, eat less meat and more vegetables, eat coarse grains in moderation , eat more easily digestible and nutritious foods, eat less fat, animal offal, and butter , and do not drink a lot of alcohol, smoke, drink cold water, or eat cold food.

Due to the dry climate in winter, the body is prone to lack of water . In a day, adults should supplement 35-40 ml of water per kilogram of body weight. Drinking water appropriately can dilute the blood. Avoid water that is too cold or too hot, which may irritate the stomach and intestines and cause blood vessel constriction.

The ground is slippery in rainy and snowy weather, so be careful when traveling

It is expected that starting from today (November 25), the high-altitude trough will move eastward and a ground low vortex will develop. The snowfall in Northeast China will be heavier. There will be heavy snowstorms in the northeastern part of Inner Mongolia and parts of Heilongjiang . The snow accumulation in Yichun, Hegang and Daxinganling areas may even be more than 20 centimeters. We must be particularly vigilant about the risk of snow disasters.

After rain and snow, the roads are prone to become slippery, snowy, and icy. The public is advised to drive slowly and carefully when going out, pay attention to traffic safety, slow down, and avoid sudden braking and sharp turns. When walking or driving, pay attention to anti-skid measures. You can use anti-skid mats, anti-skid chains and other tools to increase friction and avoid falls or traffic accidents due to slippery roads.
