Where will the temperature return to winter overnight? What should you pay attention to when the temperature drops suddenly?
The temperature across the country has played a big role. It was originally thought that the temperature has recovered in various places. However, the meteorological observatory authorities have issued a notice that cold air is about to hit. As the cold air gradually advances from north to south, today and tomorrow The northern part of the sky will gradually start the cooling process, the significantly higher temperature in the south will drop significantly, and many parts of the north will return to cold winter. Where will the temperature return to winter overnight? What should you pay attention to when dealing with sudden drops in temperature? Let’s take a look below. Temperature? Big skydiving? Where will winter return overnight?
From the 16th to the 17th, large-scale precipitation will occur in the central and eastern regions.
It is expected that from 8:00 on March 16 to 8:00 on March 17, southwestern Anhui, eastern and southern Hubei, northern and western Hunan, northern Jiangxi, middle and southwest Guizhou, and northeastern Guangxi There will be levels 8-10. Localized thunderstorms or hail with level 10 or above; short-term heavy precipitation in parts of southern Henan, central and southern Anhui, Hubei, northern and western Hunan, southeastern Sichuan Basin, central and eastern Chongqing, eastern Guizhou, northeastern Guangxi and other places, The hourly rainfall is 20-50 mm, and the local area can reach 60 mm. Local thunderstorms or strong winds or hail weather above level A; O The main impact of strong convection is expected to be from the day to the night of the 16th.
Affected by rain, snow and cold air, the temperature dropped by 4 to 10 degrees Celsius in most areas of the central and eastern parts, accompanied by northerly winds of magnitude 4 to 5, with gusts of magnitude 6 to 8, in southern Hebei and central and western Henan The temperature of other places dropped.
The national strong wind cooling forecast map is from 8:00 to 18 8:00 on March 16. The national strong wind cooling forecast map is from 8:00 on March 16 to 8:00 on the 18th.
Yesterday, Inner Mongolia and Northeast China were hit by heavy snowfall. Among them, from 08:00 yesterday to 06:00 today, moderate to heavy snow or sleet and local blizzards occurred in parts of northeastern Inner Mongolia, southeastern Heilongjiang, most parts of Jilin, and northern Xinjiang.
The dividing line between precipitation and snow is located in the southern part of North China, Inner Mongolia, Shanxi, Hebei and other places, or snowstorms; due to the development of cyclones along the Yangtze River, there are relatively heavy rains, and heavy rains occur in some areas.
In the northern region, there is mainly snow or sleet; in the south, there is mainly heavy rain, accompanied by strong convective weather. Many places in Northeast and North China have fluctuated and dropped; temperatures in the south have continued to rise, and the temperature in some areas may exceed 30 times the degree Celsius. What should you pay attention to when the temperature drops suddenly?
1. Wash your hands frequently
Frequent hand washing can prevent the transmission of cold viruses. Do not pick your nose frequently, as this will bring the virus on your hands to the nasal mucosa and cause infection.
2. Do not keep long nails
Cut your nails frequently to make them flush with your fingertips, and carefully clean the nail gaps when washing your hands to prevent excessive bacteria in the nail gaps.
3. Clean the nasal cavity
Washing the nose with cold water every day can remove dirt and viruses and enhance the adaptability of the nostrils and upper respiratory tract to cold.
4. More ventilation
Rooms, offices, and school classrooms should be regularly ventilated to reduce the accumulation of bacteria and viruses indoors and keep the indoor air fresh.
5. Get enough sleep
Poor sleep leads to low immunity and can easily lead to colds. You should ensure adequate sleep and avoid overexertion.
6. Drink more yogurt
Supplementing probiotics through yogurt, cheese and other foods can help regulate intestinal flora, reduce inflammation and prevent infection.
7. Dietary zinc supplement
Zinc can improve resistance, reduce symptoms, and shorten the duration of colds. Foods rich in zinc include shellfish, shrimp, red meat, offal and nuts. Effects of a sudden drop in temperature on the body
Effect 1: Cold stimulation increases the risk of heart disease
The drop in temperature will stimulate the body's blood vessels to constrict, thereby reducing the heat dissipation of the skin and playing a role in keeping warm. effect. However, the contraction of blood vessels will cause blood pressure to rise, increasing the burden on the heart, thus also increasing the probability of angina and myocardial infarction. Research shows that when the temperature drops by 10 degrees Celsius, the risk of heart disease increases by 7%. So how to deal with it? You should add more clothes in time according to the temperature changes. Especially in winter, the temperature difference between indoor and outdoor is large. It is important to keep warm when going out.
Impact 2: Cold stimulation makes it difficult to control blood pressure
Cold weather and temperature changes can easily cause blood pressure to be difficult to control, especially when moving from warm indoors to outdoor activities, temperature changes can cause blood vessels to Systolic or diastolic changes cause blood pressure to fluctuate greatly and become 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, take medication regularly, and seek medical treatment promptly if they experience large fluctuations in blood pressure or symptoms such as dizziness and chest tightness.
Effect 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 alcohol and consume high-calorie foods, which will lead to an increase in blood lipids. Drinking alcohol, high-fat meals, and hyperlipidemia will all lead to an increased risk of heart disease or stroke. To address this, the simplest way is to live a healthy lifestyle, eat a light diet low in salt and fat, reduce alcohol consumption, and exercise moderately. Achieving these points can not only resist the cold, maintain a healthy body, but also help maintain a beautiful figure, which is in line with the public's pursuit of health and beauty.
Impact 4: In cold weather, physical activity of most elderly people is significantly reduced, even in "cat winter"
The elderly themselves are susceptible to cardiovascular disease, and in cold weather Many elderly people stay at home and do not want to go out for activities. In cold weather, blood vessels constrict and blood flow slows down, which increases the risk of thrombosis. 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 benefits the harmony of body and mind.
Impact 5: Cold weather can easily induce respiratory infections
Due to the erosion of wind evil in autumn and winter, the incidence of respiratory infections increases significantly. Once respiratory tract infection occurs, especially lower respiratory tract infection, oxygen saturation will decrease and the body will be in a state of relative hypoxia, which will increase the decrease in vitality of tissues and organs throughout the body, such as fatigue and sleepiness, dizziness, chest tightness and shortness of breath and other discomforts, and even induce acute Myocardial infarction, stroke, etc. To address this problem, in addition to keeping warm, wear masks when going out and avoid gathering in densely populated areas to reduce the chance of respiratory disease infections such as influenza. If necessary, you can get a flu vaccine.
