Heavy rain and snow are coming! The Central Meteorological Observatory issued three early warnings, and people should pay attention to their own safety and the safety of others when traveling.

Blizzard and its accompanying gale and cooling weather have seriously affected or even destroyed transportation, communication, transmission lines and other projects, affecting people's production and life. In the face of snowstorm weather, pedestrians should pay attention to cold and anti-skid, and choose shoes with good anti-skid performance on the road. It is not advisable to wear high heels or shoes with hard plastic soles to avoid falling down and catching a cold. Near billboards, eaves, trees, etc. , pay attention to observe or bypass them, so as not to hurt people because of melting snow and ice.

Necessary anti-skid measures should be taken when vehicles go out, and vehicle anti-skid chains should be installed. When parking on ice and snow roads, you should choose a sunny, sheltered, flat and dry place to park, and you should not be close to buildings, telephone poles or other vehicles to prevent side slip. If you are trapped by snow, you should call 1 10, 1 19 as soon as possible to actively seek rescue.

Sunny weather is convenient for travel and easy to encourage people to gather in public places; On the contrary, rainy days can reduce people's gathering, make pathogenic microorganisms sink to the ground and purify the air; However, it may lead to the decrease of ventilation and indoor air quality. In terms of temperature, when the temperature is high, the human body's yang rises, blood vessels dilate, blood circulation is accelerated, human immunity is enhanced, and respiratory symptoms are alleviated, which is conducive to preventing the spread of the epidemic. When the temperature is low, people are prone to catch cold and get sick, and basic diseases such as cardiovascular and cerebrovascular diseases are aggravated, which is not conducive to epidemic prevention and control. In terms of humidity, what is the humidity? Back to Nantian? In the past, when droplets absorb water in the process of propagation, their lateral propagation distance will be shortened.

Closing the window before returning to Nantian can effectively reduce the impact of returning to Nantian. But because the epidemic needs ventilation, don't close the doors and windows for a long time. You can choose to open the window for ventilation at noon every day. In addition to preventing doors and windows from opening, it is also a good practice to spread newspapers on the floor and table to absorb moisture. Spread used old newspapers on the floor and table, especially in places that are prone to moisture, such as the door. You should spread two more layers. Hot salt water mopped the floor. Heat the water to about 40 degrees Celsius, then add a spoonful of salt to the water, stir and dissolve it, and mop the floor with salt water to accelerate the evaporation of water. Put the dehumidifier on or start the dehumidifier. Dehumidifying agents/bags can be placed in closed spaces (such as drawers, shoe boxes and wardrobes) to reduce moisture in all closed corners.
