Traditionally, the freezing of knees and joints will lead to pathological changes or leave a "root cause". Even if it's okay now, it doesn't mean it's okay in the future. So the legs really can't stand the cold and need to be well protected.

So you see, the behavior of Japanese girls wearing skirts in cold weather will definitely cause arthritis, right?

In fact, this statement has no scientific basis. People's knees may be shivering and even sour in the cold wind, but this will not bring arthritis.

At least in the current medical research, no joint injury caused by ordinary hypothermia has been found.

Do you know that?/You know what? Do you know that?/You know what? Although you feel very cold and your bare legs are frozen into ice, in fact, this is only a somatosensory temperature, and the deep tissues of people have not changed much. The reason is simple-human beings are warm-blooded animals.

The blood circulation and body tissues of the human body naturally have the function of temperature regulation, so that the temperature of the human body is controlled at about 36 degrees. If it is too cold, we will shrink pores, reduce the velocity of some blood vessels and capillaries, and avoid temperature loss. When it is overheated, we will open our pores and take the temperature out quickly through the expansion of sweat and blood vessels.

In other words, as long as you maintain healthy vitality and the temperature does not reach the extreme weather of dripping into ice, in fact, exposing your legs is not as harmful as you think, because our real body temperature has not changed much at all.

This is why the Japanese dare to show their legs. They are not afraid of the so-called "frostbitten legs". Modern medicine has proved through practice and demonstration that this situation will not induce arthritis.

If you feel uncomfortable in the cold wind, most of the reasons are the tension caused by the contraction of muscle tissue and the stimulation of low temperature on the body surface.

What's more-you already have joint lesions in different degrees, but you are more sensitive due to the stimulation of cold, and healthy joints are not afraid of cold wind at all.

At this time, it is better to diagnose and treat these problems as soon as possible. After all, the sooner joint problems are discovered, the better. Many pathological changes are irreversible, and the deeper the disease, the more troublesome it is. Many times, what you need to change is just an incorrect lifestyle, instead of thinking that it is freezing your legs and desperately adding wool pants to yourself.

The real culprit of arthritis is unscientific extreme sports, or excessive tension, and the influence of toxic chemicals. Therefore, once you find a joint problem, you'd better see a doctor. Don't prescribe medicine for yourself, add clothes and treat rheumatism. This is to reverse the causal relationship between disease and environment.

So don't worry about Japanese children barefoot. As long as it is not the extreme weather like the Antarctic, and the knee is deliberately placed at extremely low temperatures such as ice water and ice, it will not cause artificial synovial sac, fascia, ligament, bone and other injuries.

Of course, the influence of joint diseases will become more and more serious when people get old. This is an unavoidable problem, and we should not associate it with "showing your legs when you are young". Maybe they are more from your crazy cycling when you were young, excessive exercise in the gym and so on?

There were many strange traditions in China in the past. For example, my wife has never been pregnant. She brushes her teeth, gets wet in the rain and eats fruit every day. She is very healthy.

The so-called "arthritis" problem is the same. A cold can lead to arthritis. Where is this fallacy? In fact, this truth is just like confinement. Japanese, Koreans and China people are the same race. People will be fine without confinement.

Always say that your legs are frozen, and when you get old, you will get cold legs. But look at the life expectancy of Japanese people, which is the highest in the world, much higher than that of Americans. I've never heard that Japanese people's old cold legs are particularly serious.

Arthritis is not a mysterious disease at all, it has long been revealed. Arthritis is generally caused by joint pain. In fact, it can be divided into osteoarthritis, rheumatoid arthritis, gout, septic arthritis, ankylosing myelitis, juvenile idiopathic arthritis and so on. There are many reasons for joint pain, but they are all confusing.

Osteoarthritis is more common. Causes of osteoarthritis: human joints are cushion cartilage, and there is viscous synovial fluid in the joint cavity, which is somewhat similar to engine oil.

What should I do if the joint fluid is less? It's like a machine running out of oil. Without lubrication, abnormal friction between cartilage will be caused, leading to destruction and degradation. After cartilage degradation, it will not be able to protect the bone surface, leading to bone-to-bone confrontation and more pain. ,

This situation is divided into primary and secondary, some are natural, and it is easy for the elderly over 50 years old, and some are secondary, such as trauma, fracture, joint instability and so on.

The situation of rheumatoid arthritis is still unclear, which may be related to genes and environment, such as immune system problems, joint inflammation and thickening caused by attacking joints and so on.

But I have never heard of the saying that my legs were frozen when I was a child and I had arthritis when I was old.

There are many bad "traditions" in China that should be abandoned, such as confinement, especially in some feudal places, such as not washing your hair for a month and not brushing your teeth for a month. Don't believe

I was surprised when I first came to Japan. It's cold in Hokkaido in winter, and it often snows heavily, but many children run around the supermarket barefoot. But after a long time, I got used to it, and I thought, this is good.

The habit of China people is that they are always afraid that their children will be hot and cold, especially if they catch a cold or catch a cold. When it was cold, they began to add all kinds of clothes to their children. In winter, many children are wrapped like balloons for fear of catching a cold. But does it really work? I don't think so. Sometimes it even has a negative impact. Children's resistance will decline, they will wear too much, and they will easily sweat and have a fever. In fact, they are more likely to catch a cold. We never know what our children need, and we always do these things just to reassure ourselves.

Japanese children wear so little in winter. In fact, they don't often catch cold and get sick. Instead, I feel better and have strong resistance. Japanese people don't love their children as much as we do. While ensuring good health, cultivate their perseverance. In dress, they are not as sensitive as China's parents, and even seem a little irresponsible.

Of course, it's not as careless as everyone thinks. Many times we see that Japanese children wear so little in winter, sometimes because they get on the bus when they go out, and then get off and go indoors, so parents don't think it is necessary to toss. If you want to go skiing outdoors or in winter for a long time, Japanese parents will also dress their children warmly so that their legs will not be exposed.

In Japan, you will also find that most parents don't care if a Japanese child falls, and the child won't cry, but stands up and walks on. In fact, it is only the result of daily training, because Japanese children have long known that even if they cry, their parents will not take care of themselves. Might as well stand up and keep walking. This is actually a difference in educational concepts.

So sometimes foreign cultures can really give us a lot of inspiration, so it is very necessary for us to observe those angles that we have never noticed, thought about and dared to try, and always keep our learning mentality.

I don't know about this, but I know. When I was a child, my mother told me not to play in the water, but I didn't listen. Now when I was a child, I often soaked in water, and my legs always hurt or grieved [covering my face] [covering my face].

Since childhood, Japanese people think that children exercise to resist freezing and enhance immunity. Some children who are not particularly good will catch a cold at first, but after a year or two, their resistance will increase, and then they will catch fewer colds.

People's education inculcates that strong-willed people are not afraid of or can tolerate freezing.

No, they have adapted since childhood.

Are most Japanese legs? My legs were frozen stiff when I was a child.
