School bags are essential for children's study, many parents in the purchase of school bags are often only consider the appearance and durability, and neglect the health care function. In fact, children's schoolbags have a very big impact on physical development, such as the choice of improper easy to injure the spine, the formation of back, parents should pay more attention to the health problems brought about by schoolbags. So, how should we choose the right school bag? For this reason, experts from the shopping mall have offered reliable suggestions to parents.
Look at the three belts, shoulder straps, waistbands and chest bands.
Since most children's schoolbags are heavy enough to block blood flow and cause muscle injuries, especially in the shoulders, it is generally recommended that the shoulder straps be wide enough to relieve the pressure on the shoulders and evenly distribute the weight of the schoolbags, while the shoulder straps with cushions can relieve the weight of the schoolbags. Strain on the trapezius muscle.
In addition to wide shoulder straps, children's schoolbags should also be equipped with belts and chest bands. Previous schoolbags usually did not have belts and bras, only some backpacks have, but in fact the role of increasing the two belts is very big, the use of belts and bras can make schoolbags closer to the back, the weight of the bag will be evenly unloaded on the waist and disc bone above, and can be fixed in the backpack, prevent the backpack from swaying Unstable, reduce the pressure on the spine and shoulders.
Healthy bags should be light and smell free.
Children's schoolbags should be lightweight in material. Because children have to carry a large number of books and articles back to school every day, so in order to avoid the increase of children's load, schoolbags should try to choose lightweight materials. It is generally recommended that the weight of children's schoolbags should not exceed 15% of their weight.
When purchasing schoolbags, we should also smell and read the smell of schoolbags. If there is a pungent smell, then it is likely that the content of formaldehyde in schoolbags exceeds the standard, which will pose a greater threat to children's health.
Healthy schoolbags can also protect the spine and prevent back.
Because the children's spine is soft and easy to deform after long-term compression, if the bag is not properly designed or too heavy, it will easily lead to children with back. When choosing a schoolbag, you can consider choosing a backpack with the function of protecting the spine, such as a backpack with a hollow pressure-free design, can reduce the chance of the schoolbag hitting the spine, and the backboard hollow design can prevent the schoolbag from clinging to the back, so that children will not sweat. It should be noted that schoolbags with ridge protection tend to sell at higher prices.
Children with unreasonably designed backpacks are easy to contain. Parents should choose a backpack with a center of gravity inner board to place heavy books in the center of gravity inner board so that the center of gravity is close to the back, so that the back can be kept straight and the chance of containing backs can be reduced.
Using schoolbags to eliminate health risks scientifically
Even if you choose a healthy schoolbag, you should pay attention to its reasonable use. Otherwise, it will not achieve the effect of health care, and even lead to new security risks. We should do the following three points:
1. When children carry schoolbags, they should carry them as required. They must buckle up all kinds of buttons and walk in a reasonable manner.
2. Educating children to put books and stationery in their schoolbags, other things should not be put in, especially food, toys and other things. On the one hand, it is conducive to reducing the burden, on the other hand, it also avoids the spread of disease.
