Heavy, one shoulder bags are among some of the most popular types of bags to wear, but they actually come with many health risks. Holding the wrong bag can negatively affect your back more than you know. One-shoulder bags can leave you with chronic muscle pain, headaches, migraines, spinal damage, and even pinched nerves.
It is recommended to use a backpack because they evenly distribute the weight you are carrying on your back. It is important to remember to never carry more than 5-10% of your body weight.
If you are insistent on wearing a one shoulder bag, the smaller the better. Wearing a large bag hanging off of one shoulder can cause the upper trapezius muscle to begin to shrug. This happens as the shoulder adapts to the increased load.
Because the muscle attaches onto the base of the skull and extends across the entire length of the neck, there is potential to cause not only neck pain, but tension headaches as well.
With time, wearing these types of bags can lead to a straightening of the natural backward C–shaped curve in your neck. This change in shape alters the weight distribution on the discs, putting more pressure on the joints leading to inflammation, osteoarthritis, and nerve compression.
If you find yourself still wearing a one shoulder bag, try and switch sides as frequently as possible. This helps to distribute the weight. Also, opt for a thick strap over a thin strap to resist it cutting into the shoulder
