What do you need to prepare for extremely cold weather?

1. When extreme cold weather comes, prepare more warm clothes to avoid cold and fever caused by low temperature. Besides clothes, you can also prepare some foods and vegetables rich in fat and calories, such as beef, pork, ginger, pepper and so on. It has a good effect on strengthening the cold resistance of the body. In addition, we should keep the indoor temperature stable, try to keep the indoor temperature above 20 degrees, and open the doors and windows for ventilation at noon to ensure the cleanliness of indoor air.

2. If you have a solar water heater at home and don't need to use it for a long time, empty the water in the water heater and water pipe, and then close the water valve to prevent the water pipe from freezing due to low temperature. If the water supply pipeline is exposed outdoors, the exposed water supply pipeline and water meter facilities should be tightly wrapped with insulation materials, and the water supply facilities in the shade should be thickened and bound. In addition, when the temperature is too low, turn on the faucet in time to drain the remaining water to avoid freezing the water pipe.
