Why are many people in a good mood when it rains heavily? Because when it rains, the soil and the ground will secrete something called soil odor (I forget the specific name).

The organic matter produced by rain hitting the ground is very complicated. Soil contains a lot of organic matter, which is degraded by microorganisms, and some products react with inorganic salts in soil. The gas produced by this series of chemical reactions carries a small amount of ultrafine dust to stimulate our olfactory nerves.

This effect will only appear in the first rain on a hot day, and continuous rain will not produce this chemical reaction.

This smell is very fragrant, which makes us relaxed and happy, and makes us feel much better. It is rare for a landlord to be in a bad mood. Maybe you just don't like it. You think it's raining and you can't go out. Besides, the sound of rain outside is just like cooking, which inevitably makes people upset.
