Do you have the habit of waking up in the morning on an empty stomach?
Many people are keen to drink a glass of water in the morning, which can not only supplement the water lost by body metabolism during sleep, promote bowel movements, and clear the brain; It can also help reduce blood viscosity to a certain extent and reduce the incidence of myocardial infarction and thrombosis.
But some people say that drinking water on an empty stomach in the morning will cause many bacteria to enter the stomach, causing harm to human health, even more harmful than skipping breakfast.
Which of these two extremely contradictory statements is credible?
01
Drink water in the morning without brushing your teeth,
Millions of bacteria all down?
It's not that exaggerated.
Our mouth itself is a huge bacterial petri dish, in which there are more than 700 kinds of bacteria, and the number is as high as 50 billion.
But don't be afraid, many of these bacteria are good bacteria. Even if we drink harmful bacteria into our stomachs, powerful stomach acid and intestinal beneficial bacteria will help destroy these pathogenic microorganisms.
Taking a step back, it is somewhat difficult to drink bacteria by drinking water, because after a night's sleep, bacteria will accumulate on the surface of the teeth to form plaque, and the water flow cannot be washed away, and it takes brushing or flossing to remove.
Therefore, brushing your teeth first or drinking water first, in the end, is just a personal hygiene habit, don't worry too much.
In fact, except for patients with oral diseases such as periodontitis and gingivitis, drinking water on an empty stomach in the morning is beneficial to the body.

The top 3 benefits of drinking water on an empty stomach in the morning
The "Dietary Guidelines for Chinese Residents" suggests that healthy adults can drink a glass of water on an empty stomach after getting up in the morning, which can replenish the water lost due to invisible sweating and urination, and can also increase circulating blood volume.
01
Improve nocturnal dehydration
When we sleep, the body still consumes a lot of water, and drinking a glass of water in the morning can replenish the water lost by the body's metabolism and improve dehydration at night.
02
Promotes intestinal peristalsis
After a night's sleep, a large amount of water is consumed from urine, skin and breathing, and the person is in a physiological state of dehydration when waking up in the morning; Moreover, when sleeping at night, metabolic waste accumulates in the body, and drinking on an empty stomach in the morning is conducive to cleaning up the stomach and intestines, and the sense of defecation is stronger.
3
Promotes blood circulation
After a night's sleep, the blood viscosity will reach the highest value when the human body wakes up in the morning, and the blood pressure is easy to rise.
At this time, slowly drink a glass of 250ml of water, the water will enter the blood circulation, help reduce blood viscosity, shorten the residence time of platelets in the blood vessel wall, and improve blood flow.
Since drinking water on an empty stomach is generally harmless and even beneficial, how can drinking water endanger our health?

Drinking water into the misunderstanding, health care becomes hurtful
01
Drink too much, drink too hard
After getting up in the morning, people are prone to a state of lack of water, and some people are particularly thirsty, so they like to "purr" and drink fiercely.
But this way of drinking is actually not good. It is also recommended to drink small sips and multiple times.
Because human kidneys can drain about 800-1000ml per hour, if you suddenly drink a large amount of water in a short period of time, it is easy to lead to dilution hyponatremia, which in turn damages heart and kidney function.
02
The water is too cold or too hot
Some people are in a hurry to go to work and school in the morning, and they don't care whether it is cold or hot water, and they just take a sip.
However, too cold water is easy to stimulate the stomach, causing the gastric mucosal blood vessels to contract sharply, causing gastrointestinal discomfort, and even some people have diarrhea not long after drinking. Especially people with bad stomachs are simply "looking for their own guilt";
Overheated water can easily cause burns to the esophageal mucosa, forming inflammation. In the long run, the esophageal mucosa is prone to genetic mutations in the process of continuous damage and repair, inducing esophageal cancer.

Prefer honey water, light salt water, lemonade, etc
Compared with boiled water, many people prefer to add some ingredients to it, feeling that the health care effect is stronger, like honey water can laxative, lemonade whitening...
But in fact, drinking "feeding water" on an empty stomach in the morning may not be so good:
(1) Honey contains fructose, which needs to be metabolized into glucose after entering the human body, and then absorbed and utilized by the human body, so that it is not suitable for people with high blood sugar, but increases the range of blood sugar fluctuations.
(2) Morning is the first peak period of human blood pressure increase, drinking too much light salt water may make blood pressure higher.
Especially for people with high blood pressure, diabetes, cardiovascular and cerebrovascular diseases, and abnormal renal function, it is undoubtedly worse.
And in most people's daily diet, salt has exploded, so don't add more.
(3) Vitamin C rich in lemons can reduce melanin production and whiten spots, but for people with excessive stomach acid, drinking lemon water on an empty stomach is more likely to stimulate the stomach, resulting in acid reflux, belching and other symptoms.
In addition to the above matters to pay attention to, before getting up in the morning to drink water, there is actually a very important thing - do not get up too quickly.
Especially for people with chronic diseases, such as three highs, diabetes, etc., they should pay more attention to the dangerous moments in the morning.
