It is not clear when this health method began to circulate in society: drinking a glass of cool boiled water after getting up in the morning, believing it can replenish fluids, regulate endocrine function, and also be beneficial for the excretion of waste from the body. Now that the weather is hot, some people even like to put cool water in the refrigerator and drink it all in one gulp upon waking in the morning, feeling refreshed and invigorated, with an incomparable sense of relief.
According to professionals, drinking cool or iced water on an empty stomach after waking up can harm the spleen and stomach. Traditional Chinese medicine believes that the kidneys are the foundation of innate constitution, governing the body's innate yang, while the spleen and stomach are the foundation of acquired constitution, governing the body's acquired yang. When the innate and acquired yang are sufficient, one naturally does not get sick easily, and even if one does, they will recover quickly.
70% of the human body is composed of water, which is an essential substance for maintaining the body's normal function and metabolism. The correct health method is to drink warm water close to body temperature, which best aligns with the body's natural needs.
