Get up in the morning.
The body may be slightly dehydrated because it has not been replenished for a while. It's best to drink a glass of water first to get your body working again. Secondly, regularly replenish the lost water for the body.
No matter what exercise you do, drink water even after cleaning the room.
When you have a fever or a cold, you must drink water to replenish the water lost due to the increase of body temperature.
Generally speaking, the amount of water people drink every day should at least be in balance with the amount of water they consume in their bodies.
The amount of urine excreted by human body in one day is about 1 1,500ml, and the total water consumption is about 2,500ml, while the water that human body can metabolize and replenish from food and body is only about 1 1,000ml, so normal people need to drink at least 1 1,500ml of water every day, about 8,000ml.
Preferably warm water.
Does not contain calories, and can be directly absorbed and utilized by the human body without digestion. Generally speaking, it is recommended to drink warm water below 30 degrees Celsius, which will not stimulate the peristalsis of the gastrointestinal tract too much and will not easily cause vasoconstriction. Sugary drinks will slow down the absorption of water in gastrointestinal tract, and long-term drinking in large quantities will have a certain adverse effect on human metabolism. Dr. Li Baihua told reporters that sugary drinks such as orange juice and cola taste good, but they should not be drunk too much. The daily intake should be controlled at about one cup, with a maximum of 200 ml. For diabetics and obese people, it is best not to drink drinks. Domestic tap water meets the drinking water standard, and it is safe to drink boiled tap water.
Fresh boiled water is not only sterile, but also contains more than a dozen minerals needed by the human body. It is found that after natural cooling of boiled water, the chlorine in water is reduced by 50% compared with ordinary natural water, and the molecular structure of water will also change. The physical and chemical properties of water, such as surface tension, water density and electrical conductivity, have changed, and its biological activity is 4-5 times higher than that of raw water, which is very similar to that of water in living cells, so it is easily absorbed by human body through cell membrane. However, tap water can be directly drunk without boiling and disinfection, which is easy to be infected with intestinal infectious diseases such as dysentery, typhoid fever and cholera.
However, we should also pay attention to the ways and means of boiling water, not the longer the boiling time, the better, nor can we heat it repeatedly. Chlorinated tap water contains halogenated hydrocarbons and other 13 harmful substances, and boiling water is a good way to reduce harmful substances to a safe range. However, when the water temperature just reached 100 cC, the contents of halogenated hydrocarbons and chloroform were 1 10ug/ l and 99ug/l respectively, which exceeded the national standard. After boiling for 3 min, the contents of these two substances decreased rapidly to 9.2ug L and 8.3ug L, respectively, and quickly returned to the standard. If the water continues to boil, the contents of halogenated hydrocarbons and chloroform will decrease, but the contents of other non-volatile substances in the water will increase, which is also harmful to human body. Therefore, it is best to boil water for 3-5 minutes, which can completely eliminate bacteria and bacterial spores. Another misunderstanding of boiling water is repeated boiling water. In such water,
Drink water in moderation between meals, preferably once an hour. People can also judge whether they need to drink water according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is too dark, it means that they need to add more water.
