It is not advisable to stay in fog for a long time in winter. What's the harm in foggy weather?

Many people often confuse fog with haze, but there is a big difference between them. Fog is formed by water droplets and dissipates quickly, while haze is formed by various particles and dissipates slowly. It looks as if fog is harmless, isn't it just water droplets? But in fact, fog also has a certain impact on our human body.

When fog appears, the light becomes weak. We usually say that ultraviolet rays are harmful to our health, but moderate absorption of ultraviolet rays is beneficial to our health. Especially for children, we need to absorb enough ultraviolet rays to ensure the balance of vitamin D, and vitamin D is beneficial for us to absorb calcium, which is an essential nutrient for children's growth. Therefore, if there is no vitamin D, calcium will not be absorbed well, and the growth of children will be affected, which will lead to rickets in severe cases.

In foggy days, the pressure will be relatively low, which will promote the increase of blood pressure and aggravate the condition of cardiovascular patients. Moreover, if the indoor temperature is warmer and the outdoor temperature is lower, blood vessels will expand with heat and contract with cold, and blood pressure will rise, which will easily lead to stroke. Therefore, the elderly should try not to go out in foggy days, take preventive measures and try to keep happy.

With the increasing damage to the environment, the current smog weather is not just smog weather, it often contains some harmful substances, especially if there is smog, it will undoubtedly cause serious harm to the human body. Therefore, you must take preventive and protective measures when traveling in foggy days. If possible, go out as little as possible and exercise less.

In addition, foggy days have a great influence on people's mood. In a gloomy environment, people's mood will naturally become depressed. In fact, physical illness is easier to treat than mental illness. Once a person is sick, it takes a lot of effort to get better.

Don't underestimate the depression in foggy days. Frequent listlessness will lead to depression, and in severe cases, depression will occur. Depression is difficult to treat, so you must cheer yourself up on foggy and cloudy days and don't live in negative emotions all the time.
