Water and soil disorder is an adverse reaction between the body and the environment, such as plateau reaction. Human health is closely related to the natural environment, and various factors in nature have direct or indirect effects on the human body, such as climate, sound, and eating habits. However, people have the ability to adapt to the natural environment, and the size of this ability varies from person to person. When people experience physical discomfort due to a change in geographical environment, such as loss of appetite, mental fatigue, poor sleep, or even diarrhea, vomiting, panic, chest tightness, itchy skin, thinning, red spots on the skin, acne, etc., it is commonly known as discomfort from water and land. Therefore, to identify water and soil discomfort, the main thing to look at is whether there is a correlation and homogeneity between the onset of the disease and the change in geographic environment. If there is, it is a symptom of water and soil discomfort, if not, it is not.
