Some people especially like rainy days in daily life. Even if it is stormy outside, people also feel comfortable and relaxed.

This may not only be a psychological effect, because of a lot of negative ions brought by the rain, it can improve people's mood, have a certain positive impact on people, and even effectively treat depression.

In nature, stormy weather, seaside with surging waves, mountains and forests with humid air, waterfalls, etc. will fill the air with a lot of negative ions. However, where can humans get this experience in real life, that is the shower room you use every day, and the concentration of negative ions is particularly high.

Scientists have shown that a person taking a bath for 15 to 20 minutes a day can effectively prevent and treat depression. Moreover, through the shower, you can wash away the sweat, oil, and fatigue.
