The advantage is that the soles of people's feet arch upwards, which is called the arch of the foot in medicine. The arch of the foot has enough elasticity to ensure the stability of the human body when standing upright, and it has enough elasticity when jumping, which can cushion the vibration when walking and protect the nerves and blood vessels under the feet from oppression. Wearing high heels can protect and maintain the arch of the foot, so it is physiological for young women to wear high heels. But the heel should not be too high, 2 ~ 3 cm high is appropriate. If the heel is more than 4 cm, it must be very small. Wearing such high-heeled shoes will focus the body's center of gravity on a small point, which will not only fail to protect the arch of the foot, but also easily cause strain on the muscles and ligaments of the foot, causing pain in the foot and waist, destroying the physiological arch of the foot and causing flat feet. But pregnant women and older women regard wearing flat shoes as advantages and disadvantages. Under normal circumstances, high heels are worn on the feet, and the weight of the whole body is borne by the whole foot. Because the high heel design of high heels does not conform to human mechanics, the front part is tight and narrow. After wearing high heels, the body will lean forward, the whole body weight will fall on the soles of the feet, and the stress will be concentrated on the toes and uneven, while the aponeurosis of the soles of the feet will be connected with the tarsal bones and heels respectively. Wearing high heels will make the palm out of balance, destroy the normal load line of gravity transmission, and involve the knee and waist to bear pressure. If you don't pay attention, it will not only cause foot pain and sprain. Many female patients have low back pain and knee pain, but they don't think that the culprit will be high heels. Miss Fu came to the hospital for low back pain in her feet and knees, and was later diagnosed as toe cyst, osteoarthritis and lumbar ligament strain. Doctors believe that the cause of Miss Fu is foot deformity caused by long-term wearing high heels, such as bunion, back muscle ligament strain, chronic low back pain, hip and knee pain and so on. If this incorrect pressure posture continues, the situation will be more likely to deteriorate. It is obviously unrealistic for adult women to give up all kinds of high-heeled shoes, and wearing high-heeled shoes with appropriate height (below 5cm) is like installing an artificial arch on the soles of their feet, which can prevent muscle and joint injuries, relieve walking fatigue, keep their bodies straight and add physical beauty. The doctor suggested that there are several ways to wear the beauty of high heels without affecting health. First of all, the best time to buy high heels is from 3 pm to 4 pm. Try it on for ten minutes at this time, and walk more to ensure that the shoes really fit comfortably. When wearing high-heeled shoes, you can make a soft insole at the pressed place such as the forefoot or heel to reduce the pressure on the soles of your feet; The heel height of high-heeled shoes should not be too high, preferably not more than 5 cm, and the heel should not be too small, otherwise it will be difficult to stably support the weight, and the toe cap should be slightly loose to leave more space for the sole and toes. Don't wear high heels every day. 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 heels to reduce local fatigue. After coming home from work, soak your feet in warm water for at least 5 minutes, strengthen ankle exercise every day, and do some foot relaxation exercises to help stretch your tendons. Once you sprain, you should go to the hospital in time. In addition, remind adolescent girl friends that adolescent women are not suitable for wearing high heels, and it is best to wear wedges and shoes with heels not exceeding 3 cm. Females' foot bones mature at the age of 15- 16. Wearing high-heeled shoes too early makes the foot bone complete the ossification process according to the angle of high-heeled shoes, which is prone to deformity. Pelvis is a bone ring composed of sacrum, coccyx, left and right hip bones, ligaments and joints, which is usually shaped at the age of 25. Pelvis is an important structure for human body to transmit gravity. The increased load of shapeless pelvis directly affects the delivery of adults.
