In our daily life, we always hear all kinds of "medical common sense" through various channels.
Some people hear it on TV, some people hear it from other people's mouths, and some people say it's their own experience.
But none of those hearsay stories are really "substantiated".
There are several so-called "medical common sense", which are actually fake.
Fish bones stuck in the throat, drinking vinegar and eating rice?
"Doctor, I'm not going to eat fish anymore."
Fish has become a very common meat in our daily life.
But when many people eat fish, the biggest worry is that they will be stuck in the throat by fish bones, so some people choose not to eat fish.
The first reaction to a fish bone stuck in the throat is to drink some vinegar or swallow rice.
Because the ingredients of fish bones are calcium and vinegar is acetic acid, the mixture of these two can form calcium acetate, which softens the fish bones so that the fish bones can fall off smoothly, and this can also reduce the damage caused by the fish bones to other organs.
This is also a "local method" that many people believe to be true, and if someone is stuck in the throat, they will quickly drink vinegar.
But in fact, this is clever but mistaken by cleverness.
Although vinegar does dissolve fish bones, it takes at least 30 minutes or more.
It is very easy to understand that the fish bones are stuck in the throat, only a little bit of the tip of the is exposed, but the vinegar passes through the throat, and although the two will come into contact, the contact time is very short.
In addition, the content of acetic acid in our lives is very small, if we drink too much, not only will it not work, but it will also corrode our throat and stomach.
Eating rice in large gulps is also the wrong way, as it will only cause the fish bones to move deeper, which may cause infection or ulcers in severe cases.
The correct approach should be to fast, abstain from drinking, if possible, ask the family to help take out the tweezers, if it is still not possible, go to the nearest hospital in time.
The redder your face, the more you can drink?
"People who drink wine with a red face can drink very well at first glance."
When eating and drinking with friends, some people drink a little bit, and their faces immediately turn red, which is also what we call "upper face".
And at the wine table, many people will joke that people who blush when they drink alcohol must have a very good amount of alcohol, and a large amount of alcohol must be a problem.
But in fact, this statement is not correct, blushing has nothing to do with the amount of alcohol, but is a manifestation of the dilatation of blood vessels in the skin and mucosa.
No matter what kind of food, as long as it enters the human body, it will be digested and metabolized.
The metabolism of alcohol depends on acetaldehyde dehydrogenase 2 in the liver, and the acetaldehyde dehydrogenase 2 in people with a large amount of alcohol is completely sufficient.
However, people with blushing have less acetaldehyde dehydrogenase 2 in their bodies, which means that the body is relatively slow to metabolize alcohol.
In this way, the alcohol that has not been metabolized will be retained in the body, and it will also stimulate the dilation of blood vessels, and blushing is the reaction after being stimulated.
Therefore, in fact, people who drink alcohol and blush do not drink a lot of alcohol, and the reason for the upper face is that the endocrine function has been imbalanced.
If you are blushing from drinking or if your friends are blushing from drinking, then you need to be careful and avoid drinking as much as possible.
Related to drinking, there is also a medical common sense that makes many people "mistakenly believe that it is true".
Drink alcohol in moderation to prolong your life?
Many people who like to drink will laugh when they are persuaded by others to drink less, and then prevaricate with the saying that "drinking in moderation is good for health".
Some people who like to drink alcohol must do something every day is to "have a drink", for example, the bottle of mineral water may not contain water, but "wine".
It is also said that in winter, a sip of wine can warm up the body and also promote metabolism.
Many people believe that drinking one, two, two taels of liquor every day does not have much impact on physical health at all.
But the fact is that the liver level of people who drink alcohol all year round is very different from that of people who don't drink.
A clinical study done by American scientists showed that even moderate alcohol consumption will actually accelerate brain atrophy and increase the number of amyloid plaques.
"Drinking alcohol hurts the body", this is not a joke, but there are exact experimental data, even if you only drink a little bit, in fact, it will have some negative effects on the body.
Many people pay lip service to drinking in moderation, which is good for their health, but in fact it is just an excuse to comfort and deceive themselves.
If it really has no effect on the body, why is alcohol classified as a Group 1 carcinogen by the World Health Organization?
Therefore, alcohol, whether you can drink without drinking or drinking, is not to drink less and in moderation, but not to drink.
10,000 steps a day, live past 100 years old
It seems that the topics of health and longevity have been of great interest to people since ancient times.
As long as everything has to do with longevity, then its popularity is definitely very high.
I don't know when the slogan "10,000 steps a day, live 100 years old" appeared in people's mouths.
Many people firmly believe that as long as they walk 10,000 steps a day, they will definitely live longer, so they start to insist on walking every day.
But this statement is not entirely correct, because our knee joints have a service life.
In general, the normal life of the knee joint is 60-75 years.
If we overuse our knee joints when we are young, then it will shorten its service life, and it may be forty or fifty years old that the knee joint will have problems.
In addition, excessive exercise will cause a very large burden on the knee joint, and may also cause chronic joint damage.
Walking is a great way to keep you fit, but not the more you walk, the better.
According to relevant research, the number of steps per day is about 6,000, which is a relatively stable and normal value, but the specific number of steps also varies from person to person.
If someone has a knee injury or has other special circumstances, then just exercise moderately.
Seasonal infusions to unblock blood vessels?
At the turn of the season, many elderly people go to the hospital for infusions.
In their view, infusion during the change of seasons seems to prevent cerebrovascular disease, that is, by infusing saline or glucose into the blood vessels, to flush the blood vessels, so as to avoid blood vessel blockage.
But this is actually a complete "misunderstanding" of people, which seems to be very reasonable, but in fact there is no basis.
To some extent, the infusion can play a dilating role, and it can improve the blood circulation of the brain.
But this is also a premise, that is, at the onset of the disease, the use of relevant drugs for infusion, rather than blind infusion.
Besides, if you blindly infuse fluids, it is very likely that you will also have drug allergies or increase the load on the heart, so that good intentions do bad things.
Especially for the elderly whose cardiopulmonary function itself is not very good, if they blindly go to the infusion, a large amount of fluid will enter the body in a short period of time, which will increase the load on the heart.
