脚又被称人体的第二心脏。人的双脚上存在着与各脏腑器官相对应的反射区，当用温水泡脚时，可以刺激这些反射区，促进人体血液循环，调理内分泌，增强人体器官机能，取得防病治病的保健效果。

同时热刺激会使足部微循环加快，使得水中的药物成分快速地被吸收，直接进入人体血液循环，达到养生的效果。

The feet are also called the second heart of the human body. There are reflection areas corresponding to the organs on the human feet. When the feet are soaked with warm water, these reflection areas can be stimulated to promote human blood circulation, regulate endocrine, enhance the function of human organs, and obtain health care for prevention and treatment effect.

At the same time, the thermal stimulation will accelerate the microcirculation of the foot, so that the herb ingredients in the water are quickly absorbed, and directly enter the human blood circulation to achieve the effect of health maintenance.
