Wearing a backpack properly is important to help prevent back and shoulder pain. So, how should one be worn properly?
1. Firmly on both shoulders! One-sided carrying leads to a side bent posture and back and shoulder pain. Loose bags can swing causing chaffing. Too much pressure can cause arm tingles if the circulation or nerves are compromised in the shoulder region. It is much better to evenly disperse the weight across both shoulders.
2. Higher on the shoulders, about an inch above the waist. Carrying backpacks too low can cause a sway back posture or for you to lean forward to much, and can add pressure to the shoulders causing pins and needles in the arms.
3. If there is a waist or chest strap, use it as this helps disperse the pressure more evenly.
4. Kids backpacks should weigh no more than 15% of their body weight. So 30kg child should not carry more than 4.5kg
6. Clean bags out regularly to minimise unnecessary weight.
7. Consider a second bag for all those library books.
8. Pack the bag well. Heavier items should be down the bottom and closest to your back
