Backpack Safety from KidsHealth

Backpacks come in all sizes, colors, fabrics and shapes and help kids of all ages express their own personal sense of style. And, when used properly, they're incredibly handy.

Many packs feature multiple compartments that help students stay organized as they tote their books and papers from home to school and back again. Compared with shoulder bags, messenger bags, or purses, backpacks are better because the strongest muscles in the body — the back and the abdominal muscles — support the weight of the packs.

When worn correctly, the weight in a backpack is evenly distributed across the body, and shoulder and neck injuries are less common than if someone carried a briefcase or purse.

As practical as backpacks are, though, they can strain muscles and joints and may cause back pain if they're too heavy or are used incorrectly.
