London, England is covered with white. What kind of weather do you like when it snows?

Due to the heavy snow, London, England is covered with white. Although the snow scene is beautiful, I prefer sunny weather to snowy days.

First of all, sunny weather is good for traffic. As we all know, the road surface is slippery on snowy days, which is prone to traffic accidents. Due to the deep snow on the road and the reduced visibility, vehicles can't travel fast, and traffic jams are easy to occur, which brings great inconvenience to pedestrians such as office workers. At the same time, because the road is slippery, pedestrians are prone to fall. Sanitation workers have to clean up the snow, which undoubtedly increases their workload. In addition, too deep snow is easy to cause snowstorms, which brings great challenges to people's production, life and work. On the contrary, in sunny weather, people don't need to worry so much. Everyone can travel, do outdoor sports and so on at any time.

Second, in clear weather, ultraviolet rays in the air can kill bacteria and block the spread of viruses. People usually put quilts, sheets and clothes in the sun on sunny days. Strong ultraviolet rays will kill mites and other bacteria and keep clothes clean and tidy. In sunny weather, old people and children will also sunbathe outdoors. On the one hand, they can use the bright sunshine to drive away the haze in their hearts and keep a good mood. On the other hand, sunbathing can supplement calcium and promote bone absorption. But if it is snowy, old people and children should not go out, because winter is the season of high incidence of respiratory diseases, such as COVID-19, which is raging all over the world. In cold winter, the epidemic situation is more serious and more contagious. In addition, due to the low temperature, people are prone to colds, coughs and even flu.

Third, the weather is sunny, the temperature is moderate, and the human body is comfortable, which is suitable for the rehabilitation of patients with chronic diseases. Due to chronic diseases such as hypertension, diabetes and hyperlipidemia, some elderly people can go out for a walk, jog and exercise in sunny weather, which can effectively control the disease. However, if it is snowy, some hypertensive patients can't control their blood pressure well, which will easily lead to dangerous diseases such as arteriosclerosis, stroke and hemiplegia. In addition, when it snows in winter, people can't go out, can't exercise properly, and get fat easily.

However, everything is a double-edged sword. Although snowy days bring inconvenience to our life and work, heavy snow can freeze pests to death and make crops harvest in the next year. Although sunny weather brings convenience to our daily life, a lot of dust will accumulate in the air, leading to low air quality. So we need four seasons to change, both sunny and snowy, and the four seasons alternate. This is life, life.
