3 kinds of backpacks are easy to destroy health

One side of the shoulder is the most damaging: For adults, the most common backpacking method is a single shoulder backpack. Regardless of the lady's favorite shoulder bag, even if it is a backpack, many people are also used to unilateral shoulder back. Experts said that an incorrect backpack posture is one of the important factors that cause health risks. Long-term shoulder bags, especially when the bags are heavy, are often used for unilateral backpacks in order to load the weight of the backpack or to prevent the bags from falling down. Unconsciously lifting one shoulder, while the neck is not consciously inclined to the other side, this will cause the shoulder muscles to contract, tight, invisible will cause shoulder muscle strain, shoulder pain will appear within a short time problem. In the long run, long-term fixation of one side of the backpack will cause tension between the neck and the oppressed shoulders, and the spinal force will be unbalanced, which can lead to dislocation of the intervertebral disc or cervical spondylosis.

Heavy shoulder bag also hurts: In addition to the backpack position, the weight of the bag caused to the human body can not be ignored. Mobile phones, computers, books, etc. Now people's backpacks are loaded with too many items, plus the appearance of a beautiful and beautiful bag itself is not small, these virtually increase the burden on the spine. In fact, the weight of a backpack is harmful to health. It is no longer a new thing. Even if it is a shoulder bag, if the weight is too large, the shoulder and back muscles (such as the trapezius and the scapulae) will be oppressed and the soreness will be inevitable. In addition, the heavier the backpack is, the greater the pressure on the knee joint is, and it is easy to produce joint problems.

Handbag compresses the arm nerves: even if it is a clutch bag, whether it is hung on the arm of the arm or lying in the hand, it will also cause pressure on the side arm of the shoulder bag. If you change hands when you are unwell, you will oppress the nerve and cause the blood circulation of the arm to change. Bad, and then produce pain. Experts advise that the farther the bag leaves the body when it is unilaterally bagged, the greater the impact on the spine from the perspective of force balance. The impact is long-term gradual and difficult to detect. When the problem erupts, the damage has already been caused.
