Getting up in the morning and drinking a glass of water is a very healthy habit, but should we brush our teeth first or drink water first? Should I brush my teeth or drink water first when I get up in the morning? Drinking water in the morning and getting into the good habit of drinking water on an empty stomach can cleanse the intestines and bring digestive enzymes from saliva into the stomach and intestines, and help break down food more fully when eating to promote digestion. However, this morning brushing teeth and drinking water also have to pay attention to? The old ancestors passed down a saying “morning skin wrapped in water, water wrapped in skin before going to bed, health and longevity, 100 years old is not a surprise.” That refers to drink water in the morning on an empty stomach, and diligent foot soak at night, can be healthy and long life.

Some people worry that if you brush your teeth first to brush away the digestive enzymes in saliva, wouldn’t it be a pity? In fact, the digestive enzymes in saliva, only when you eat something to have the role of decomposition and digestion of food, do not eat, it is in the “rest” state. And people in sleep saliva secretion is very little, so the production of digestive enzymes is also very little. And the human gastrointestinal tract itself has digestive enzymes, saliva only produces a very small part, its digestive effect is minimal, even when brushing teeth is brushed away, it will never affect the digestion of food. The former said, “After waking up and before brushing your teeth (the best time to drink water in the morning), drink seven heaps of good water in the raw.” One is one hundred and eighty milliliters, seven water is equal to one thousand two hundred and sixty milliliters. Of course, drink less than one thousand two hundred and sixty milliliters, drink four hundred milliliters also become. The most important thing is to drink water before brushing your teeth!
