Oversized totes that carry a lot of weight may cause your upper shoulder muscles to hold themselves in a shrug as you adapt to heavier loads. In addition to neck and shoulder pain, carrying an oversized tote can cause your weight distribution to come off balance and place pressure on your joints, causing inflammation.

Carrying a tote bag can be detrimental to your shoulder and spinal health if used incorrectly or overloaded. Because a tote bag is typically worn on one side of the body, it creates an asymmetrical load that forces the muscles in the neck and shoulder to work harder to keep the bag in place and balance the weight. This often leads to "tote bag shoulder," where the shoulder is instinctively hiked up, causing muscle strain, tension headaches, and even nerve compression over time. Long-term use can result in a tilted posture or a slight curvature of the spine as the body tries to compensate for the uneven weight. To minimize these risks, ergonomic experts recommend switching shoulders frequently, choosing bags with wider or padded straps, and keeping the total weight of the bag under 10% of your body weight. For heavy daily commutes involving laptops or books, a backpack is almost always a healthier alternative as it distributes the weight evenly across both shoulders and the hips, protecting the delicate alignment of your musculoskeletal system.
