First of all, drinking "enough" water includes the total amount and times of drinking water every day. The daily alcohol consumption of mental workers is about 0.0326 times of body weight; The daily water consumption of manual workers is about 0.0434 times of body weight. According to the weight of 70 kg, the daily drinking water is about 2.3 -3.0 liters. On average, the water we supplement by eating every day is about 1.2 liters, so we can calculate the range of extra drinking water needed every day as1.65,438+0 liters-1.8 liters. According to the estimation of the capacity of drinking cups of 200ml, the amount of drinking water per day alone is 5 -9 cups. In order to facilitate memory, it is generally described as "8 glasses of water a day". The frequency of drinking water is roughly divided into 8:00 am, 9:00 am,11:30 am according to the time; Afternoon 13:30, 15:30,17: 30; 19:00 and 20: 15 in the evening. It should be noted that the more hydration is by no means the better, but it is estimated according to your own physique. Of course, if the total amount is seriously below the lower limit, it will also lead to abnormal metabolism.
Secondly, drinking "appropriate" water includes the difference between people drinking water in normal environment and stress environment. Under normal circumstances, according to the total amount of drinking water, take the initiative to drink water according to time and frequency, instead of waiting for "thirst" to remember to drink water; In the stress environment, including winter, summer, exercise, work and other abnormal environments, it is suggested that we supplement nutrients such as salt, vitamins, minerals and amino acids in water to cope with the stress environment.
