2021May 19, a fitness corner in a park in Shenyang, Liaoning Province, a big tree was covered with uncles and aunts hanging their necks for fitness. Everyone hung their heads and shook and swayed with the rope. On the morning of May 2 1, a video of # Shenyang granny hanging her head on a tree to exercise # was quickly posted on the hot search list, which attracted wide attention from netizens and triggered a hot discussion among them. Some netizens think this kind of exercise looks very effective, but others think it is dangerous. I think this kind of exercise is very unscientific.

I believe that when netizens exercise in the park, they can often find that some uncles and aunts exercise in a strange way, and the 57-year-old uncle Sun's exercise is even more strange. Uncle Sun spontaneously developed a traction device. He hung the traction device on a tree, and everyone bowed their heads and swayed back and forth with the rope. Uncle Sun said that he had cervical spondylosis before, so he thought of inventing a traction tool for the activity room. He believes that this tool can repair cervical spondylosis and improve the affected areas of the neck and shoulders. I think if the cervical vertebra is uncomfortable, you should see a doctor in time.

The cervical vertebra refers to the cervical vertebra, which is located below the head and above the thoracic vertebra. Long-term strain will deform the cervical spine, causing problems such as insufficient oxygen supply and pain. We found that people who often sit in the office, or people who often play mobile phones, will have some deformation in their cervical vertebrae. After deformation, we will feel pain or headache. Many people will see a doctor at the first time, and some hospitals will take traction. Clinical traction has indeed alleviated the pain of these patients. I think it may be that clinical traction made 57-year-old Uncle Sun invent a traction device himself. However, the traction device he developed personally is not scientific and is not desirable during exercise. Because the maximum weight that a person's cervical vertebra can bear is about 25 kg, neck-hanging fitness is equivalent to loading the whole body's weight on the cervical vertebra, which may not only damage the nerves and spinal cord, but even cause high paraplegia.

Although daily exercise is good for our health, we must adopt correct exercise methods and invent some ourselves? Indigenous method? Sometimes it is harmful to our health. If we do have some diseases that cause some symptoms in our bodies, we must seek medical advice in time. After all, many treatments have been obtained through thousands of clinical trials, and they are still relatively safe and secure.
