When you get up in the morning, usually drink 50-80ml of warm water, the water intake should not be too much and not too little. If you drink more than 80ml of water in the morning, for example, the gastrointestinal tract will be too full and swollen, which will affect the breakfast meal, it will not be easy to eat when eating breakfast, or there will be a low concentration of gastric acid impact and dilution in the gastrointestinal tract, causing malabsorption and digestion, if the water intake in the morning is too little, less than 50ml, then it will not be able to replenish the body overnight. If the water intake in the morning is too little, less than 50ml, then it is not able to replenish the water lost by the body overnight, for the nourishment of the cells and for the effective supply of cells and can not play a full hydration effect, so the amount of water drunk in the morning in 50-80ml of warm water is the most scientific.
