The posture of the backpack is also very important. For example, the shoulder bag is used as a shoulder bag. The excessive shoulder straps cause the bag to constantly shake the center of gravity. The "pressure" that is caused by the spine is unusual, and the adverse effects even exceed Ordinary shoulder bag. So be sure to figure out how to pack a healthy backpack:

The proper length of the shoulder strap helps stabilize the center of gravity, and the body's muscles do not constantly adjust for the constantly shifting center of gravity, and are ultimately damaged by overwork.
2, the location of the backpack can not be too low: want to comfortably backpack bag, bag can not be too low. For example, the lower edge of the shoulder bag is preferably in the pelvic position. The Messenger bag is best placed on the lumbar side, the upper edge of the backpack is about the location of the pelvis.
3, it is best not to stand in front: whether it is a messenger bag or a shoulder bag, from a health point of view are best not to stand in front of. Because of the stress, the body will lean forward when standing behind, and it will easily cause "hunchback."
4, regular shoulder change: everyone has their own favorite backpack habits, experts advise, if you use a single shoulder bag or Messenger bag must be regularly changing the shoulder, so can play a role in preventing cervical and spinal strain.
