According to our latest dietary guidelines (2022), it is recommended to drink adequate amounts of water, in small quantities. In mild climates, low physical activity level adult males drink about 1700m of water per day and adult females drink about 1500ml per day. The human body is about 70% water, and drinking water helps maintain blood pressure, regulate temperature, transport nutrients, and excrete waste. Drinking adequate amounts of water also helps to maintain a good body weight because it maintains a healthy metabolism and reduces appetite. Studies have found that drinking water before meals has some weight control effects. It can be increased in moderation according to individual health conditions, like kidney stone patients can increase the amount of water under the guidance of the doctor. Be careful not to drink large quantities of water at a time. Excessive water consumption may aggravate the burden on the kidneys and the heart, and in extreme cases, may even lead to symptoms of water intoxication.
