Many kids get excited about picking out a backpack for the school year; it lets them put style and personality into a basic school necessity. But picking a stylish backpack doesn’t always mean it’s the best for their health. Mayo Clinic found that many students’ backpacks weigh more than 15 percent of their body weight, which has led to some school-age children complaining of back pain. But not to worry, there are several things that can help ease the stress a backpack can put on your child’s body, like clearing out the clutter and eliminating unnecessary books that add too much weight. Now you can help them be book-smart, in more way than one!
