Finnish bath is also called sauna. "Sauna" is Finnish, meaning "cabin without windows", which is probably related to the origin of sauna. By using the cold and hot stimulation of repeated dry steaming and water washing, blood vessels can be repeatedly expanded and contracted, which can enhance the elasticity of blood vessels and prevent arteriosclerosis.

I often go to Lady Kim Spa, which is a professional spa. You can search Shanghai Golden Lady SPA through Baidu first to find out.
