The right bra can protect the breasts, prevent them from sagging, and enhance the beauty of women. Nowadays, body shaping bras have become the new favorite of young women who love beauty, but this kind of sexy and beautiful bra is not necessarily suitable for everyone. Inappropriate bras or improper wearing may cause lumbar and back pain, and even cause you to suffer from cervical spondylosis. Many women have similar situations. They usually like to wear small or narrow-band bras because they can highlight their figure. But this kind of bra is like adding a "wire mesh" to the human body. When the human body is in continuous motion, the upper limb shoulder muscles are constantly moving, and the bra frequently rubs in a small range of the skin. Over time, these muscles can be overly fatigued, blood circulation is impaired, and over time, the neck muscles, blood vessels, and nerves are compressed, resulting in upper limb numbness, neck pain, dizziness, and nausea. Clinical examinations will find that the local muscles of the shoulder and back, such as the latissimus dorsi, scapular angle muscles, and sternocleidomastoid muscles, are aged to varying degrees, and X-ray examinations show hypertrophic changes in the cervical spine. Clinically, this type of symptom is called "bra syndrome." "Bra syndrome" is caused by long-term use of narrow-band bras or bras that are too small or too tight, especially for body shaping underwear. Because too small underwear or too tight underwear straps will compress the neck muscles, blood vessels, and nerves, affecting the cervical spine, causing cervical strain and bone hyperplasia, and then affecting the vertebral nerves and vertebral arteries. It causes shoulder and back pain, chest tightness, dizziness, nausea, numbness in the upper limbs, and a tingling sensation when the head and neck are rotated. In addition, underwear that is too small or underwear straps that are too tight will also restrict the movement of respiratory muscles, and the chest cavity will not contract and relax smoothly, thus affecting respiratory function. It causes insufficient ventilation of the two lungs, resulting in symptoms such as chest tightness and shortness of breath. |
