1. It Can Cause Back Pain
If you carry a heavy bag every day it not only affects your arm and shoulder (we’ll get to that) but it forces you to over compensate with other muscles to hold up all that weight, and it causes you to move differently. You walk differently as your weight is shifted and that change in your normal range of motion can lead to back pain. In addition, if your bag is really heavy, then every time you put it down or pick it up you are using your back muscles, which could cause you to strain a back muscle, and as anyone who has thrown their back out knows, it’s really painful, and really annoying to recover from. And over time stress on your back could lead to “increased risk of scoliosis (curvature of the spine) or kyphosis (hunchback) in women with weak bones.”
