芬兰桑拿浴：一种有益健康的传统习惯
In Finland, many people take a sauna every week. A sauna is a small, hot room made of wood. People sit inside and let the heat relax their bodies.
The sauna is very warm — around 80 to 100 degrees Celsius. This heat makes your heart beat faster. It helps your blood move better through your body.
