Tips for using different types of bags, be a healthy 'backpacker'

The widespread use of backpacks is closely related to our life. From the perspective of health and minimal impact on the body, the backpack is undoubtedly the best choice, and the messenger bag can reduce the burden on the spine to a certain extent while paying attention to the posture, shoulder bags are the most likely to cause health risks among several types of backpacks. The following is a compilation of some suggestions from relevant experts. Backpack (1) The closer you are, the better. When you pack your backpack, you should shrink your abdomen and relax your arms. The closer and shorter the strap is to your body, the easier it will be to carry it back. Because the backpack is too high, if the backpack is too heavy, the strap should be shortened to keep the bag as close as possible to the trunk of the body, and the height should be maintained between the thoracic vertebra and the lumbar vertebra. (2) Put the heavy things in the center, put the heavy things in the center of the backpack, do not simply change the posture of the body when walking, if there are many things, the weight is large, can be divided into two small bags, one shoulder, one hand, loose weight. (3) When you buy a backpack, put a book and try to carry it for 3 minutes. When you buy a backpack, put a book in the bag first, let the bag have a little weight, try to carry it for 3 minutes, and see how comfortable the shoulders are, as well as the size of the contact surface between the bag and the body, the degree of compliance, etc. , try to choose the small scale, the back bandwidth. (4) Try to choose a backpack with a wide shoulder strap. The shoulder strap is too thin or too short, which will affect the blood circulation of the shoulder and neck, or squeeze the arm nerve, which will form excessive squeezing on the arm and arm, so choose a backpack with a wide shoulder strap as much as possible. Shoulder bag or messenger bag (1) Be good at carrying handbags as little as possible. Handbags are the most harmful to women's waist. Both single shoulder and handbags simply form excessive pressure on one side of the body, causing the body to lose balance. When carrying a single handbag, the force is straight down, the other side of the waist is required to exert force, which will cause strain if it is not careful. In addition, when carrying a bag, the elbow joint with many and thin nerves should also exert force, making it easier to get injured. Therefore, the handbag should be as light as possible, and the weight should not exceed 10% of the weight. When carrying the bag, it is best to hang the bag in a place far away from the elbow joint. The muscles here are relatively strong and can support the weight of the backpack. (2)'Back Center'And'Back'Best,'Back Center' The meaning is that the bag is just between the arm and the trunk, and the hand is quietly clamped. This method can reduce the strength of the shoulder. 'Back' It means that if you don't like to hold the bag, it is better to move the bag back than to move forward. Since the muscles of the waist and back are more than those of the chest and abdomen, the force that can be accepted is more. More importantly, if the bag is carried in front for a long time, the gravity is in front, and the body will unconsciously lean forward, the Hunchback is very beautiful, and the back is good for the body to stand upright. (3) Arm-in-arm bag is better than hand-in bag. Carrying the bag with hand, the joint of the arm needs to swing back and forth, bend and stretch, which is very simple to form tennis elbow, while arm-in-arm bag can train biceps brachii. However, it should be noted that if one arm is pulled for a long time, it is very simple to show that one arm is thicker and the other is thinner, and it is only possible to rotate the left and right hands.
