Recently popular saying: "7 cm is the health limit of high heels". So, is there any scientific basis for this argument? In the end how high high heels are detrimental to the human body?
According to the analysis of some experts, the “health standard†for high heels is less than 7 cm, and if it exceeds 7 cm, it becomes a torture device for both feet.
Doctors at Harvard Medical School in the United States studied the effect of high-heeled shoes on knee joints. The study subjects were 20 healthy women with an average age of 34.9 years, an average height of 1.62 meters and an average weight of 59.1 kg. Each subject chose a pair of high heels with a heel height of 7 cm. The torsional forces of the bilateral knee joints in barefoot and in high heels walking were measured, and the values ​​were statistically analyzed and compared. The results showed that wearing high-heeled shoes is 30% higher than that of barefoot walking. If the height of the heel is reduced, the torsion of the knee joint is also reduced, but it is higher than that of barefoot walking.
According to Xu Hui, deputy chief physician of Orthopaedic Department of Beijing Jishuitan Hospital, wearing high heels can make the center of gravity of the body forward. Long-term in this state, it will cause changes in the normal force of the hip, waist, and other parts of the body, causing pain in related parts; And the normal weight of the arch will change, and the center of gravity will lean forward, which will inevitably increase the weight of the forefoot, causing foot pain and foot problems. Xu Zhuren said that any height of high-heeled shoes will cause changes in the force of the arch and other parts, but the degree of change and the size of the problem.
From another point of view, the structure of the human foot is not exactly the same, no matter how high and high, as long as people wear a suitable, will not cause foot pain and disease on the line.
For flat feet, proper padding is beneficial. Director Xu said that for ordinary people, less than 4 centimeters is less harmful to the human body.
According to an Oxford University professor's article in the epidemiology and public health magazine, 55.2% of women with arthritis wear high heels, while 67.1% of healthy women wear high heels. Therefore, the professor said: "The traumatic joints, excessive smoking, and excessive body weight are the culprits causing joint diseases. In this case, it is not reasonable to attribute the cause of joint disease to high-heeled high heels. of."
Director Xu Hui said that the height of shoes to wear varies from person to person. As long as the shoes you wear are suitable for you, you don't need to walk and you can't hurt your feet. You don't necessarily choose to follow them.
Some doctors also suggest that when wearing high-heeled shoes, you can make a soft insole on the forefoot or the heel of the foot to reduce the pressure on the sole. The height of the heel of the high-heeled shoes should not be too high, and the heel should not be too small, otherwise it is difficult to stabilize. To support weight and easy to stomp, the toe should be slightly loose, so that the foot and toes a little more space. High-heeled shoes should not be worn everyday. Women who need to walk for a long time may wish to prepare a pair of comfortable flat shoes in the office and wear them alternately with high-heeled shoes to reduce local fatigue.
In addition, Director Xu also reminded adolescent girls and adolescents that adolescent women are even less suitable for wearing high heels, because women's mature bones are 15-16 years old. Wearing high heels prematurely results in the ossification of high-heeled feet in accordance with high-heeled angles. Malformation. The pelvis is usually set to 25 years old. The pelvis is an important structure for the human body to transmit gravity. The undefined pelvic load will increase, which will lead to pelvic stenosis and directly affect the delivery of adults.
