According to the theory of Western medicine, it is possible to touch cold water during menstruation, but this has a great deal to do with one’s constitution. Some people are weak and can easily get sick if they touch cold water during menstruation. If you are in good health, a small amount of exposure to cold water is not a problem. In Chinese medicine theory, it is usually believed that women’s innate ability to resist cold is weaker than that of men, and when menstruation is weak, the immune system is weakened, and the body’s resistance to external germs is also declining, so if you come into contact with cold water, it is easy to cause cold invasion, causing discomfort or illness. According to TCM theory, it is not recommended to touch cold water or eat cold things when you have your period. As mentioned above, for Chinese people, it is best not to touch cold water during menstruation, but of course this also depends on the individual’s constitution.
