Is there a "manual" to follow for drinking water? Indeed! Drinking water must also be scientific.
1. Pay attention to water quality: The water must be clean, filtered water. Although various beverages contain water, they are also mixed with various chemicals. For example, coffee can stimulate the adrenal glands, and juice can stimulate the pancreas, etc.
2. Pay attention to the amount of water: A healthy person should drink at least 8 to 10 glasses (240 ml per glass) of water per day. If you have a large amount of exercise or live in a hot area, you need to drink more water. The formula for daily water intake provided by the International Medical Research Institute in Los Angeles, California, USA is: For those who are not very active, 15 ml of water is needed for every half kilogram of body weight; if you are an athlete, you should drink 20 ml of water for every half kilogram of body weight.
3. Pay attention to the best time to drink water: The principle should be to drink evenly during the day and night. Do not drink 4 large glasses of water continuously within 1 hour. The best times to drink water each day are:
A After waking up in the morning: You must drink water, as it is key to starting the body's operation for the day (during sleep, about 200 ml of water is lost through evaporation from the skin, and one urination is about 250 ml, totaling at least 450 ml of water lost by the human body overnight). It is best to drink 450 ml of water on an empty stomach in the morning, sipping it slowly. After drinking, walk slowly for a hundred steps or do simple exercises; do not sit still;
B Around 10:00 AM: The water you drink at this time can replenish the water lost during work;
C Around 3:00 PM: This is exactly the time for afternoon tea;
D Before bedtime: Because the concentration of blood increases during sleep, drinking water can dilute the blood.
4. Special times when you need to drink water:
A After exercise: Although we are not athletes and our exercise volume is not that large, no matter what kind of exercise you do, you should drink water after it, such as after cleaning a room. This will make you less tired and less likely to have body aches;
B In an air-conditioned environment: It is especially important to replenish water;
C During pregnancy: Water is particularly needed, at least two liters of water per day, but avoid drinking water during meal times;
D When losing weight: Water is especially needed, as it can help flush out fat from the body;
E When you have a fever: A large amount of water is lost, and drinking more water can replenish it in time;
F When flying: Due to increased pressure and severe dehydration, you need to drink more water.
Drinking 8 glasses of water evenly throughout the day not only makes you healthier, more radiant, and youthful, but also helps you stay slim. Therefore, do not wait until you feel thirsty to drink water. Of course, some people should not drink too much water, including:
1. Kidney patients;
2. Heart patients;
3. Patients with cirrhosis of the liver.
