Every time it rains on cloudy days, I feel particularly comfortable. Why?

First of all, rain is often accompanied by lightning, which can release ozone factor and play a bactericidal role in the air. Secondly, rain will directly purify the air, the air is fresh and the breathing is more pleasant. And when it rains, the temperature will drop, especially in summer, when the temperature drops and the air flow increases, the mood will naturally get better. Also, when it rains, sounds and pictures can also play a role in decompression and relaxation.
