Everyone knows that drinking a glass of water early is good for your health, but what are the main benefits? There are also many, such as drinking water early, what's the best drink for the first glass of water? Please take a look at the following. It is very necessary to drink a glass of water on an empty stomach after getting up. There are three main advantages:
Replenish the water lost by metabolism during sleep
Reduce blood viscosity and promote blood circulation
Let the brain quickly return to a state of lucidity
If you don't have this habit, it's recommended to start from now on, especially for people with cardiovascular and cerebrovascular diseases.
However, these benefits are premised:
First of all, boiled water is the best choice
Some people drink honey water in the morning, some light salt water, some lemonade, and some milk
But these waters are not as real as a cup of light boiled water.
There is no protein, carbohydrate, fat and any heat in boiled water, so it can be called "zero burden" water. It can be absorbed by the human body without digestion, so that the blood can be diluted quickly and the blood circulation can be promoted.
Honey water
It's a good choice for people with constipation, but remember to use cold or warm boiled water.
Lemon squash
People who have too much acid in their stomach may feel sick if they drink lemonade on an empty stomach.
Dilute brine
It's not recommended to drink it. In the morning, the human body is in a state of water shortage. At this time, drinking salt water will only make matters worse.
Moreover, the daily intake of salt should be controlled within 6G. Drinking salt water is easy to lead to salt exceeding the standard.
milk
Not very recommended, for lactose intolerant people, drinking will appear abdominal pain, diarrhea and other symptoms.
Secondly, it is not suitable to drink too much at one time
According to the Chinese dietary guidelines (2016 Edition), one cup (200ml) of water can be drunk on an empty stomach after getting up in the morning, which can be used for a few times.
But for patients with kidney disease or some metabolic diseases, it is necessary to determine the amount of water to drink under the guidance of doctors.
Finally, the water temperature should be well controlled
Too hot (more than 65 ℃) water, easy to burn the mouth, esophagus, may also induce cancer.
Too cold water may cause vasoconstriction of gastric mucosa and cause gastrointestinal discomfort.
The most suitable water temperature is 35 ~ 40 ℃, neither too cold nor too hot.
After getting up in the morning, should you brush your teeth or drink water first?
Drinking water without brushing your teeth = drinking bacteria?
It is said that drinking water directly without brushing your teeth in the morning will bring bacteria and dirt from your mouth into your body and round it up, which means drinking bacteria.
It's not that scary.
When I wake up, there are many bacteria in my mouth, but not all of them are bad, and there are many beneficial bacteria in them.
As long as the total number of bacteria is controlled within the normal range and the dynamic balance is maintained, there is no need to worry.
Even if you drink them with water, there is also the stomach insurance. They will eventually be killed by stomach acid and beneficial bacteria in the intestine.
So, whether to brush your teeth or drink water first depends on your personal habits.
However, if you have oral problems, it is recommended to brush your teeth first and rinse your mouth in time after meals.
