4. Worsens Posture

We’re almost always looking into our phones and this can negatively affect our posture. Studies have noted that the typical forward neck posture that people have when they’re on their phones can, in the long run, cause injury to the structure of the cervical and lumbar spine as well as the ligaments. This, in turn, could lead to changes in the form and biomechanics of the rib cage (under which the lung contracts and expands), leading to problems with breathing. Due to this, bad posture is linked to respiratory issues.
