When the moisture comes in summer, the spleen is the most afraid of being wet among people's internal organs. When moisture is blocked in the spleen and stomach, you will lose your appetite, feel drowsy and feel depressed. Soaking feet in summer helps to dispel summer heat and dampness, prevent colds, cheer people up, stimulate appetite and promote sleep.

The theoretical reason is somewhat similar to the dog days application of "treating winter diseases in summer". Because summer is the hottest season in a year, according to the theory of "correspondence between man and nature" in traditional Chinese medicine, the yang of human body is also the most vigorous in summer. At this time, soaking feet with warm water can better stimulate the meridians and invigorate the visceral function of the human body, so people with poor spleen and stomach are more suitable for soaking feet in summer. When the spleen and stomach are good, it is not easy to be attacked by moisture, and the symptoms mentioned above will naturally be alleviated.

In addition, from the point of view of meridians, the foot is one of the most dense acupoints in the human body, and there are reflex zones corresponding to various internal organs. The meridians of the spleen, stomach, liver, kidney and other important organs all pass through here, and the health care and treatment effects of the viscera can also be achieved by conduction through the meridians when soaking feet.
