The strongest rain and snow this year is coming!
On January 26, the Central Meteorological Observatory issued the first blue warning for 2022. From the 26th to the 29th, a wide range of rain and snow covered more than 20 provinces, and some parts of the 8 provinces had heavy to heavy snow, and locally there were heavy snow or extraordinarily heavy snow.
When the blizzard and freezing rain hit, how should we respond scientifically? "Life Times" (search for "LT0385" in WeChat to follow) combined with this round of weather interview experts to teach you the correct posture for heating.
Experts interviewed
Feng Chonglian, chief physician of the Department of Traditional Chinese Medicine of the Third Affiliated Hospital of Guangzhou Medical University
Han Shuhua, deputy chief physician of the Department of Respiratory Medicine, Cuo University Hospital, Southeast University
Zhang Tao, deputy chief physician of the Department of Orthopedics, the Fourth Affiliated Hospital of Harbin Medical University
In which cities will Blizzards and freezing rains occur?
According to the Central Meteorological Observatory, from the 26th to the 29th, there will be light to moderate snow or rain to snow in the central and eastern parts of the Qinghai-Tibet Plateau, the eastern part of the northwest region, the western part of North China, the western and southern parts of Huanghuai, Jianghan, Jianghuai, the western and northern parts of Jiangnan, and the north-central part of Guizhou.
Parts of eastern Gansu, southern Shaanxi, western and southern Henan, Hubei, Anhui, western Jiangsu, northern Hunan, and northern Guizhou have heavy to heavy snowstorms;
Hubei, central Anhui, southeast henan and other places have local heavy snow or extraordinarily heavy snow;
There is freezing rain in parts of southwest hubei, guizhou, central and western Hunan, and northwest jiangxi.
The strongest period of rain and snow will occur from the night of the 27th to the day of the 29th. According to the chief meteorological analyst of China Weather Network, this round of rain and snow lasts for a long time and has a large amount of precipitation, so we must pay attention to precautions.
Will this Spring Festival be colder than in previous years?
Rain and snow with the cooling of the attack, this year's Spring Festival holiday will appear low temperature weather?
The Central Meteorological Observatory expects that under the influence of rain, snow and cold air, there will be another low-temperature rain and snow weather process in the central and eastern regions from January 31 to February 4 (during the Spring Festival holiday of Chinese New Year's Eve).
The temperature in most parts of the central and eastern regions will gradually decline, gradually turning to a normal or low level compared with the same period of the year, especially in Henan, Anhui, Hubei, Hunan, Jiangsu, Zhejiang and other places throughout the day, and will continue until the Spring Festival.
After the end of this round of rain and snow, the south will maintain a low temperature state for a long time.
Heating focus in the north and south: cold protection vs drought resistance
Some netizens joked like this: You are in the southern sun with heavy snow, and I am in the heating in the north for four seasons. Rain and snow weather blessing of the north and south, how to scientifically heat?
Southern heating: dehumidification
There is no central heating in the southern region, and the indoors are cold; the external weather is wet and cold, and the invasion of moisture and cold is easy to cause a variety of diseases.
◎Avoid humid environments
Go out to pay attention to snow and rain, change wet clothes in time, and try to avoid staying in a humid environment for a long time.
◎Use good heating equipment
The air conditioner temperature is set at about 20 ° C, do not blow directly at the head; clean the air conditioning filter and heat dissipation fins regularly.
Select a qualified electric heater, check the plug, socket, wire connection before use, and the electric heater cannot cover the items when working.
Check whether there is electricity leakage before using the electric blanket, do not open it all night; the elderly, infants, and diabetics have low skin sensitivity and should be used with caution.
◎Insist on exercising
Insisting on an appropriate amount of exercise every day can not only enhance blood circulation, but also accelerate the discharge of moisture from the body.
Northern heating: hydration
Indoor heating accelerates the loss of water in the human body, causing a variety of diseases, commonly known as "heating syndrome".
◎Go out to keep out of the cold
If you go out to use warm babies, do not paste directly on the skin, to paste across the clothes, it is recommended to paste up to 3 to 4 hours, if there is skin redness, body discomfort should be removed immediately.
◎Use a good humidifier
It is recommended to add distilled or purified water to the humidifier; the comfortable humidity in the room should be between 20% and 50%, and the humidifier should be used with a hygrometer.
If the phenomenon of "foggy" occurs when using a humidifier, it is necessary to open the window for ventilation and disperse the water mist.
◎Daily ventilation
Ventilate once in the morning and once in the afternoon, about half an hour each time, and try to open the window as little as possible in the haze weather.
◎Pay attention to hydration
Drink more warm boiled water to relieve the dry heat in the body, and the daily water intake of normal people should be 1500 to 2000 ml.
Rain and snow weather travel tips
When traveling on rainy and snowy days, first pay attention to anti-slip.
4 locations will slip
After the snow, the slipperiest part of the street actually has a regular pattern.
When passing through these places, people should pay special attention to or try to avoid: 1. Zebra Crossing; 2. Subway or underground passage exit; 3. Frequent car traffic; 4. Tiled places.
Holding things in both hands, it is easiest to fall
Holding things in both hands, the body is not balanced, and after falling, it is impossible to free up the hand to help the ground, and it is likely to be seriously injured. Similarly, walking with your hands in your pocket makes it difficult to react quickly when you fall.
If you go out with something on a snowy day, it is best to carry a backpack to free your hands and react immediately when danger occurs.
Go out on a snowy day with an exclusive gait
When walking on snow, move the center of gravity forward, try to make the soles of your feet touch the ground, and make your calves perpendicular to the ground;
If the road surface is frozen, do not rub against the ground, otherwise it is easy to trip, and you should lift a little foot when taking each step.
In addition, pay attention to walking in small strides and be careful to take the "first step" that is most prone to slipping.
Deep grooves, soft soles are the most non-slip
The sole grooves are deeper, so that the friction and grip of the road surface are stronger.
But it should be reminded that although the trenches are deep, the soles are hard, and if the seams are stuffed with snow, they will be more slippery. The sole should be soft on the basis of the deep groove and can be firmly "stuck" to the road surface.
There are now a lot of professional snowshoe soles that are made of non-slip materials and are available. ▲
