The imbalance is exacerbated when working at a desk for a long time or using a smartphone in an unbalanced posture. Through the back of the body, you can see the difference in shoulders or shoulder height at a glance. When the body is twisted, the shoulder is bent and it can lead to diseases such as cervical disc, myofascial pain syndrome, decreased intestinal function, chronic headache, back pain, and neck and shoulder pain. If the shoulder height difference becomes severe, diseases such as scoliosis, herniated disc, myofascial pain syndrome, and spondylolisthesis may appear, so you need to pay attention to your posture. Our back and back can also be said to be a scale that tells us about our health signals.
