Pack It Right: Heavy Things Close to Your Back
A backpack seems simple, because you stuff in your books, zip it shut, and go. But a pack that is loaded badly can make your shoulders ache and your back feel sore by the end of the day, and a few smart habits can make it feel much lighter.
Start with what goes inside. Put the heaviest items, like a big textbook, close to your back, in the part of the pack that touches you. Heavy things that sit far from your body pull you backward, and then you have to lean forward to keep your balance, while lighter things, like a jacket or a lunch, can go toward the outside.
Next, check the straps. Use both of them. Carrying a pack on one shoulder makes one side of your body do all the work, and your spine may twist to make up for it. Tighten the straps so the pack sits high and snug instead of hanging low near your waist. Some packs also have a belt around the middle, and if you clip it, your strong hip muscles will share the weight.
Last, clean out your pack once in a while. Old papers, extra water bottles, and things you do not need all add weight. Your back carries what you carry. If your pack still feels too heavy, ask a teacher or parent how to lighten the load.
