According to National Health Commission of the People’s Republic of China, more than 3 million people suffer from scoliosis, including over 1.5 million teenagers. Scoliosis can cause back pain and other illness like shallow breathing and insomnia. However, to some extent, the overweight bags are the culprit of children’s scoliosis. In addition, the pungent smell produced by inferior materials of bags is also harmful to people’s health. Therefore, if you are picking your child's school bag, please be scrupulous and prudent.

Here are five key tips for you.

The tip number one is to keep a watchful eye on the weight of the backpacks. According to American Chiropractic Association, child’s backpack weights should keep in no more than 5 to 10 percent of his or her body weight. Light-weight bags are beneficial to alleviate burdens on users’ shoulders and do not stunt the growth of bones.

The tip number two is to attach importance to workmanship of the backpacks, including straps and sponge fillings in the joint of the bag and strap. Straps should be broad to decrease the stress caused by backpack and disperse weight. Adjustable straps are also necessary which can avoid wobble, so as to protect user’s cervical vertebra and spin. And the soft sponge fillings can prevent shoulder pain and improve the comfort.

The tip number three is to choose bags with natural and smooth appearance. The accessories, such as zippers, should be fixed, otherwise they will scratch users’ skin.

The next one is its fabric. Choosing acceptable products of a regular company and checking the basic information about the product, for example, product model, trademark, production date, batch number and so on. Formaldehyde in production cannot exceed 300 milligrams per kilogram and the high limit of lead is 90 milligrams per kilogram. Informal business may use exceeding chemicals and terrible fabrics which are detrimental to people’s health, especially children. Don’t sacrifice safety to its beauty.

Finally, the size of backpacks should be well-fitting to users’ height. Both too big and too small bags will increase the burden on body. Generally speaking, there will be a reference table in every online store. You can also obtain the information by customer service.

In summary, choosing a school bag is a technology. Buying a safe, suitable and high-quality backpack can give you a pleasure life experience.
