Why do people feel bored when it rains?

Because it was sultry before it rained.

When it rains, the clouds are low and cover the air like a quilt. If the heat and moisture in the air cannot be released, the air will be sultry. In addition, people's sweat doesn't like to dry, and sweat can't spread out of the body quickly, so it feels particularly stuffy.

Because of the rich water vapor and high air humidity in summer, when the temperature is not too high (relatively speaking), people feel sultry, just like in a steamer. Such weather is called sultry and high temperature. Because people like to take a sauna in this weather, it is also called "sauna day". It often appears in China's coastal areas, the middle and lower reaches of the Yangtze River and South China.

Extended data:

The formation of rain requires three basic conditions: water vapor, updraft and concretion. When the weather is very hot in summer, water evaporates to form water vapor, which collects on the surface. At the same time, the air is heated and the density becomes smaller, so it moves up quickly with water vapor.

Every long summer, the air pressure is relatively low, especially before rainy days or storms, the air pressure will become lower. The main reason for feeling sultry is high temperature, the air is full of water vapor, which slows down the evaporation of skin moisture, and the air density is low and the oxygen content is low.
