Drinking water is a small thing, and many people may have done it wrong. Today we are going to pick up a few truths and rumors about drinking water.
The truth about drinking water
How much do you know?
1
Mineral water, distilled water, tap water
Which one is better to drink?
It's all good, but plain water is the most economical.
Compared to other types of drinking water, mineral water is not much different except that it has more minerals. In addition, mineral water and distilled water are mainly due to different processes and different content of trace elements.
The main purpose of drinking water is to replenish water, and from this point of view, there is no difference between these waters, and they are the same.

Drink 8 glasses of water a day?
8 glasses of water is just a theoretical concept.
The average daily water requirement of adults is more than 2500ml, of which about 1500~2000ml comes from direct drinking water, and the rest is ingested from food.
Also, pay attention to drinking water:
(1) Don't wait until you're thirsty to drink water.
(2) Drink water regularly: drink 100~150ml of water every 1 hour or so.
(3) Pay attention to the temperature of the water when replenishing water in summer: cool boiled water around 10 °C is more appropriate.
(4) After exercise, you should take small sips of water and appropriately supplement some salt.
3
When is the healthiest time to drink water?
Drink in the morning when you wake up (most effective on an empty stomach).
Under normal circumstances, 300~400ml of water is lost every night for breathing and skin evaporation, and the blood is in a relatively viscous state in the morning.
Therefore, drinking water after waking up in the morning can not only replenish the water lost due to the body's metabolism and wash the emptied stomach and intestines, but also effectively dilute the blood, reduce blood viscosity, and prevent the occurrence of cardiovascular and cerebrovascular diseases.
