盡量使用兩邊肩帶

背包勿超重

  時代越進步，學生的書包就似乎越重。除書本外，還有衣服，電腦等。這等東西可令書包過重，縱然使用兩邊肩帶，學生仍須頭肩前傾才可平衡書包的重量。這樣便會影响頸肩的弧度。一般可接受的重量上限為人体體體重的10-15%，即一名30kg 的學生，他的書包不可重過 3-4.5kg。

Students seem to be carrying heavier loads. Books, after school clothing, and laptops are heavy contents. Even when worn properly with both straps, leaning forward to compensate for the weight can affect the natural curve of the spine. A good rule to follow is keep the weight at 10-15 percent (or less) of the

person’s body weight.  A student of 30kg ( body weight), his or her school bag should not exceed 3-4.5kg.

背囊的款式
肩帶要寬，這可避免過窄肩帶壓着肩膊血管及神經線而引致痛楚。背囊附有盤骨帶亦是不錯的設計，此舉可將部份重量分散在盤骨上，減低肩部及背部負荷。
單肩設計的背囊可能合潮流，但在背負重量上不設合人體工學。
另背囊的物料及裝飾亦會形响本身的重量，選購時亦要注意。�
 

Backpack Style 

Make sure the backpack has wide straps. Narrow straps can be painful on the shoulder and press on nerves and blood vessels. Backpacks with waist belts are preferred. This helps to distribute the weight of the backpack on the pelvic bone and reduce stress onto the shoulders and back.  Backpacks with only one strap might be trendy but it is not ergonomically design for carrying weight.  The weight of the backpack when empty is also to be considered. .

Wearing a backpack on one shoulder can cause a person to lean to one side in order to handle the uneven weight. Over time, this can cause excessive stress on upper and lower back, neck, shoulders and even functional scoliosis.
