浮箱，在我们还不知道这个词的时候，美国老人已经大胆地尝试用它来健身了。其实．所谓的浮箱是以玻璃钢为原料制成的箱子，使用时往箱内注入一定浓度的盐水和天然芳香剂。当老年朋友来到SPA中心时．就可以享受这项服务：只需裸身浸入浮箱，即处于半浮半沉的状态。将箱门关闭，在水温渐渐升高时，香味也愈来愈浓，有些香味还可让健身者渐渐进入高质量的深度睡眠状态。
Floating box, when we don't know the word yet, the old Americans have boldly tried to use it for fitness. In fact, the so-called float box is made of FRP as raw material. When it is used, a certain concentration of brine and natural aromatics are injected into the box. When old friends come to SPA center, they can enjoy this service: they only need to dip naked into the floating tank, that is, they are in a semi-floating and semi-sinking state. Close the door of the box, and when the water temperature gradually rises, the fragrance becomes stronger and stronger. Some fragrances can also make the fitness worker gradually enter a high-quality deep sleep state.
