How to Use a Backpack
Backpacks are often an essential item for helping students carry their books and supplies to school. However, wearing a backpack improperly or carrying one that is too heavy can lead to injury. To check if your child’s backpack is too heavy, watch him or her put it on. If it’s a struggle and the pack seems too heavy, remove some of the books to carry in the child’s arms to ease the load. Encourage older students to make frequent locker stops during the day to drop off or switch out heavier books. Backpacks are designed to distribute the weight of books and supplies across some of the body’s strongest muscles. However, children and teens who wear their backpack incorrectly or carry one that is too heavy are putting themselves at risk for injury. Muscles and joints may be damaged and lead to severe neck, back and shoulder pain.
