Now that many children are back to school, it may be time to take a close look at the packs they use to carry books and schools supplies with them.

Now, many young students use backpacks. If the pack is too heavy or the contents not distributed in the right way, back pain, shoulder strain and muscle pain can occur.

Keep the packs to no more than 10 to 15 pounds in weight and make sure the straps are wide and adjusted correctly. School is a challenge enough with adding back pain to it.
