after a night's sleep, the body will consume a lot of water from breathing, skin, and urine, in a state of water shortage. Therefore, the first glass of water is particularly important in the early morning. There is a "health side" said: drink a cup of brine in the morning, defecate and detoxify. I want to tell you a sad news: it is wrong for you to stick to "good habits" for several years. "A glass of brine in the morning" is not scientific. Many people like to drink a cup of brine on the empty stomach in the morning, which is helpful to eliminate constipation.
in fact, drinking light brine on an empty stomach can not prevent constipation, and may also pose a threat to health. 1, the brackish water does not pass, nor does the detoxification saline contain sodium ions, so osmotic pressure is higher than boiled water. Theoretically, ingestion of hypertonic liquids is indeed good for defecation. But only high concentration of salt water can achieve a certain osmotic pressure and play a role in catharsis.
