I believe that after everyone read this news, most people immediately put away their Erlang legs.
Recently, a post-90s girl in Hengshui, Hebei Province, entered the total feeling of low back pain, so she went to the hospital for examination, and found that her legs were 1.5cm apart, commonly known as the ---- "long and short legs".
After detailed questioning, the doctor found that the girl usually liked the legs of the stilt erlang, and the long-term stilted erlang legs caused one side of the pelvis to be lifted, and then there was a false short leg.
Why do people always like to stomp their legs?
The main reason is ---- too! refreshing! finish!
When the human body is in a vertical sitting position, there is no support point on the lower back at this time, and the weight of the upper body is borne by the waist and hips, and the pressure felt by the hips is relatively large.
If you lift Erlang's legs at this time, when the sitting posture is tilted to one side, the back is resting on the back of the chair, the pressure center will begin to tilt backwards, the body weight will gradually transfer to the waist, and the pressure on the hips will be reduced, so the human body will feel comfortable.
In simple terms, it is a normal sitting posture, the ass is uncomfortable, if you stilt up the legs of the second lang, the ass is comfortable, you are only temporarily comfortable.
Why say for the time being? As a medical practitioner, I still recommend that you do this kind of casual action, really don't do it again!
You are on a leg, accumulating over time, and the damage is your body!
Seemingly inadvertent actions, in fact, the harm is really quite large
As an urban white-collar worker, he seems to be intellectually elegant and bright on the outside, but in fact, erlang's legs are cocked under the table. What are the hazards of the legs of the stilted erlang?
1. Knee pain
Unlike the signals that the body reacts to the brain, the body does not feel comfortable when the legs are stilted, but the person's lacquer joints are in an uncomfortable state when the legs are tilted.
If you twist the legs of Erlang for a long time and twist the knee joint, it will cause knee joint pain, and such a knee joint will not only hinder people's normal movement, but also hinder the progress of some exercises and affect physical health.
Especially for people whose knee joints are not very good, the legs of the stilted Erlang are exacerbating the symptoms, so people with knee joint diseases should avoid the legs of the knee joint.
2. Injury to the spine
Most people are in a hunchback state when they are cocked. This sitting position is extremely harmful to the human spine.
Under unintentional compression, the spine will change from an upright state to an S-shaped curvature, and in the long run, the human spine will be deformed, and symptoms of lateral bending or herniation of the lumbar disc will appear.
3. Strain the muscles
For the muscles of the waist, long-term stilted legs will make the muscles in a tight state for a long time, and the muscles are very prone to muscle strains and are not easy to recover.
In order to ensure the normal functioning of the back muscles, it is necessary to reduce the number of times the legs are cocked.
4. O-shaped legs
The legs of the stilt erlang are generally put on one leg obliquely on the other leg, and the force of the upturned leg will deviate, and the force of the entire leg cannot be symmetrical as in the normal posture, so the most serious part of the force on the stilted erlang leg should be the inside of the knee joint.
In the long run, the cartilage inside the knee joint will always be rubbed to cause more serious damage than other parts, and the ligaments on the outside of the knee will also appear loose or misaligned due to long-term pulling, which will eventually lead to the formation of acquired O-shaped legs.
Fifth, compress the nerves
One of the legs that is pressed underneath the legs is in a state of squeezing, in which the nerves in the legs are compressed and cause tingling.
In the long run, the compressed nerves will not function properly, resulting in the body being unable to walk on its own and other consequences.
6. Block the blood vessels in the leg socket
Like the leg nerves, the leg socket blood vessels of the upper legs will also be compressed, and the compression of the blood vessels will cause the flow of blood to be weakened or even blocked, and finally cause serious consequences such as varicose veins.
I really can't help but stomp on Erlang's legs, what should I do?
Because the legs of the stilted jiro are so comfortable, for those who sit for a long time, they always lift their legs without paying attention.
If you really want to stilt, then it is recommended to stilt your feet, rain and dew are wet, to avoid one side of the leg to bear too much gravity; at the same time, it is recommended not to exceed 15 minutes when stilting, change posture or stand up for a while.
However, I still hope that everyone can maintain a correct sitting posture as much as possible, after all, the stilts are pleasant, and the stilts are too hurtful!
