Do you have any practical knowledge of astronomy and meteorology?

When the temperature 18 degrees, the brain is the most agile; Above 35 degrees, people's brains will feel tired; Although low temperature makes the human brain awake, the efficiency of using the brain is not ideal. Strong green or light blue can calm people and easily eliminate brain fatigue; Crimson, on the other hand, strongly stimulates people and excites the brain, but then tends to suppress it.

A stable climate with little increase or decrease in air pressure, temperature and humidity is beneficial to people's longevity. Because the older you get, the more sensitive you are to climate change.

All courts in Sicily, Italy, still follow the stereotype that crimes committed during the Sirocco season should be given a light sentence, because the scorching Sirocco wind often makes people dizzy and lose their minds.

Recent studies have also found that there is a certain relationship between meteorology and human behavior: some special weather will break the balance of positive and negative ions in the air, causing people's emotional fluctuations, which will lead to abnormal and uncontrollable behavior.

For a long time, people have a misunderstanding that the freshest time for air should be in the morning. In fact, on the contrary, air pollution is the most serious in the morning, evening and evening, with the highest peaks at 7 pm and 7 am. In a year, the air is freshest in summer and autumn, and the air pollution is heaviest in spring and winter. The air is fresher and cleaner during the day, noon and afternoon. Fresh air makes your exercise more effective. Should you adjust your schedule for your health? As an important tool of office modernization, copier has been widely used in enterprises, institutions, institutions and schools, but its harm to health has not attracted people's attention. Copying machines will produce a lot of harmful chemicals in their work. Inhalation into the lungs will induce many upper respiratory diseases and even lead to lung cancer. Therefore, the copier room should pay attention to ventilation and dust removal; In addition, people who have worked in the computer room for a long time should regularly go outside to breathe fresh air.

Heat Island Effect and Diseases

People who live in cities will find it increasingly hot and unbearable in summer. That's true. According to meteorological observation, in recent years, the temperature in major cities in China has risen to varying degrees. In addition to Nanjing, Wuhan and Chongqing, which are known as "stoves", the temperatures in Changsha, Hefei, Jinan, Fuzhou and Zhengzhou have been rising every year in recent years, and some of them have become veritable "stoves". The main reason for this result is the urban "heat island effect".

Urban "heat island effect" means that the temperature in the city is higher than that in the surrounding areas, especially in summer, the temperature difference between the urban area and the suburbs is several degrees, and the temperature in the countryside is lower than that in the suburbs. When we describe the surface temperature on a map, we can clearly see that the city is a high temperature area, and the temperature decreases from the city center to the suburbs. If red is used to describe the high temperature area and blue is used to describe the low temperature area, the city is like an island in the sea of Wang Yang, which is called the urban "heat island effect" in meteorology.

How is this "heat island effect" formed?

With the high concentration of urban industry, coal ash, dust, carbon dioxide, heat generated by industrial boilers, waste gas, automobile exhaust and energy gas consumed by residents cover the city. They are good at absorbing long-wave radiation and raising temperature. Modern industrial cities expand, high-rise buildings are connected, roads are vertical and horizontal, ponds are filled, vegetation is destroyed, and the role of regulating temperature no longer exists, while cement buildings and roads have small heat capacity and strong heat absorption capacity. Under the scorching sun in summer, the temperature on the road is 18 degrees higher than that on the land, and the temperature on the cement roof is 20 degrees higher than that on the grass. Due to a large amount of heat absorption during the day and continuous heat dissipation at night, the urban temperature can't drop. Coupled with the dense population of modern cities, household appliances such as refrigerators, microwave ovens and air conditioners are widely used in families, which has contributed to the high temperature weather.

Many human diseases are caused by the "heat island effect" Under the action of urban "heat island effect", the temperature in every place in the city is not the same, but presents a closed high temperature center. In the high temperature area, the air density is low and the air pressure is low, resulting in cyclone updraft. Because the atmosphere is continuous, various waste gases and chemical harmful gases around it constantly supplement the high temperature area. Under these harmful effects, residents in high temperature areas are prone to digestive diseases, which are manifested as loss of appetite and indigestion; Gastrointestinal tract and ulcerative diseases are increasing, and the recurrence rate is high. The nervous system is seriously damaged, manifested as insomnia, irritability, anxiety and memory loss; Suffering from depression and mental depression. The number of respiratory diseases, bronchitis, emphysema, asthma, sinusitis and pharyngitis has also increased. Air pollutants can irritate the skin, leading to dermatitis and even skin cancer. Through observation, it is also found that in summer when the temperature is seriously high, urban residents with high mercury and chromium content are prone to kidney damage. Chromium entering the eyes can cause conjunctivitis and even blindness; Mercury can damage people's kidneys, accompanied by abdominal pain, vomiting and poisoning.

In this case, how to prevent the "heat island effect"?

Experts at home and abroad are actively conducting research and exploration in this field, and there are many ways to reduce the "heat island effect". For example, the surface of urban buildings can be painted white or replaced with light-colored materials to reduce the absorption of solar radiation. Planting flowers and trees on the roadside, gardens and roofs can reduce the temperature of the city. Strengthen urban planning, choose a reasonable urban structure model, establish the concept of urban ecology, and make overall arrangements for factory areas and residential areas. Especially in the heat island area, it is necessary to strengthen greening and improve the urban microclimate by absorbing the heat of plants. It is also an important measure to centrally control the dispersed heat sources in urban areas, improve the utilization rate of industrial heat sources and energy sources, and reduce heat loss and release.
