Where will the temperature "parachute" back to winter overnight? What should I pay attention to when the temperature drops suddenly?

The temperature in the whole country plays a great role. People think that all places are getting warmer. However, the meteorological station authorities have issued a notice that cold air is coming. With the gradual advance of cold air from north to south, the cooling process will be started in the north one after another today and tomorrow. The obvious high temperature in the south will drop sharply, and many places in the north will return to the cold winter. What about the temperature? Skydiving? Where will it return to winter overnight? What should I pay attention to when dealing with the sudden drop of temperature? Let's take a look together.

Temperature? Skydiving? Where will it return to winter overnight? From 16 to 17, large-scale precipitation will occur in the central and eastern regions.

It is estimated that there will be 8- 10 in southwestern Anhui, eastern and southern Hubei, northern and western Hunan, northwestern Jiangxi, southwestern Guizhou and northeastern Guangxi from 8: 00 on March/kloc-0 to 8: 00 on March/7. Thunderstorm, gale or hail weather above local 10; There are short-term heavy rainfall in parts of southern Henan, central and southern Anhui, Hubei, northern and western Hunan, southeastern Sichuan Basin, central and eastern Chongqing, eastern South China, Guizhou and northeastern Guangxi, with an hourly rainfall of 20-50 mm and local thunderstorm gale or hail weather of more than 60 mm; O It is estimated that the main influence time of strong convection is 16 from day to night.

Affected by rain, snow and cold air, most parts of the central and eastern regions cooled by 4? 10? C is accompanied by northerly winds of 4 to 5, and gusts of 6? At level 8, the temperature in southern Hebei and central and western Henan dropped.

The national gale cooling forecast map is from 8: 00 to 18 on March 6, and the national gale cooling forecast map is from 8: 00 to 18 on March 6.

Yesterday, Inner Mongolia and Northeast China were hit by heavy snow. Among them, from 08: 00 yesterday to 6: 00 today, there were moderate to heavy snow or sleet and local snowstorms in northeastern Inner Mongolia, southeastern Heilongjiang, most of Jilin and parts of northern Xinjiang.

The dividing line between precipitation and snowfall is located in southern North China, Inner Mongolia, Shanxi, Hebei and other parts of the country or snowstorms; Due to the development of cyclones along the Yangtze River, there is relatively heavy rain, and heavy rain occurs in some areas.

The northern region is dominated by snow or sleet; The south is dominated by heavy rain accompanied by strong convective weather. Many places in Northeast China and North China fluctuated and fell; The temperature in the south continues to rise, and the temperature in some areas may exceed 30 degrees.

What should I pay attention to when the temperature drops suddenly? 1, wash your hands frequently.

Washing hands frequently can avoid catching cold virus. Don't pick your nose often, it will bring the virus on your hand to the nasal mucosa and cause infection.

2, don't leave long nails.

Cut your nails regularly so that they are flush with your fingertips. When washing your hands, carefully clean the nail seams to prevent too many bacteria in them.

Step 3 clean the nasal cavity

Washing your nose with cold water every day can remove dirt and viruses and enhance the adaptability of nostrils and upper respiratory tract to cold.

4, more ventilation

Rooms, offices, and school classrooms should be ventilated frequently to reduce bacteria and viruses gathered indoors and keep the indoor air fresh.

Step 5 get enough sleep

Poor sleep leads to low immunity and easy to catch a cold. We should ensure adequate sleep and avoid overwork.

6. Drink more yogurt

Supplementing probiotics with yogurt, cheese and other foods is conducive to regulating intestinal flora, reducing inflammation and preventing infection.

7. Dietary zinc supplements

Zinc can improve resistance, relieve symptoms and shorten cold time. Foods rich in zinc include shellfish, seafood, shrimp, red meat, viscera and nuts.

The effect of sudden drop in temperature on the body: cold stimulation increases the risk of heart disease.

The decrease of temperature will stimulate the contraction of blood vessels in the body, thus reducing the heat dissipation and warmth of the skin. However, vasoconstriction will lead to an increase in blood pressure and increase the burden on the heart, thus increasing the probability of angina pectoris and myocardial infarction. Studies have shown that the risk of heart disease increases by 7% when the temperature drops 10 degrees Celsius. What should we do to add clothes in time according to the temperature change, especially when the temperature difference between indoor and outdoor is large in winter, it is very important to keep warm when going out.

Impact 2: Cold stimulation makes blood pressure difficult to control.

In cold weather, the change of temperature difference is easy to make blood pressure difficult to control, especially when it is transferred from warm indoor to outdoor, the temperature change will lead to the change of blood vessel contraction or relaxation, which makes blood pressure fluctuate greatly and difficult to control. This will lead to a significant increase in cardiovascular and cerebrovascular accidents, such as acute myocardial infarction, angina pectoris, cerebral infarction and cerebral hemorrhage. In view of this situation, patients with hypertension should strengthen blood pressure monitoring and use drugs regularly. If blood pressure fluctuates greatly or there are discomfort symptoms such as dizziness and chest tightness, they should seek medical advice in time.

Impact 3: Cold stimulation can easily increase blood lipids.

Hyperlipidemia is closely related to cardiovascular and cerebrovascular diseases. In the cold season, in order to resist the cold, people are more willing to drink and eat high-calorie foods, which will lead to an increase in blood lipids, while drinking, high-fat meals and hyperlipidemia will all lead to an increase in the risk of heart disease or stroke. In view of this, the simplest way is to realize a healthy lifestyle, a light diet with low salt and fat, reduce drinking and exercise moderately. Doing these well can not only resist the cold and maintain a healthy body, but also help to maintain a beautiful figure, in line with the public's desire for health and beauty.

Impact 4: In cold weather, the physical activity of most elderly people is obviously reduced, even? Cat winter?

The elderly themselves are prone to cardiovascular diseases, and many elderly people are reluctant to go out in cold weather. In cold weather, vasoconstriction and slow blood flow will increase the risk of thrombotic diseases. Therefore, in autumn and winter, everyone should do more exercise, especially the elderly should exercise moderately, which not only ensures the smooth flow of blood, but also is conducive to the harmony of body and mind.

Impact 5: Cold weather can easily induce respiratory tract infection.

Due to the erosion of colds in autumn and winter, the incidence of respiratory infections has increased significantly. Once respiratory tract infection, especially lower respiratory tract infection, will lead to the decrease of blood oxygen saturation, and the body will be in a state of relative hypoxia, which will increase the vitality of the whole body tissues and organs, such as fatigue, drowsiness, dizziness, chest tightness, suffocation, and even induce acute myocardial infarction and stroke. In order to solve this problem, in addition to keeping warm, wearing masks when going out, avoiding gathering in crowded places, reducing the chance of respiratory diseases such as influenza, and injecting influenza vaccine when necessary.
