These two diseases can already develop in younger students. Irina Perren, a pediatrician at the Children's Clinic of the European Medical Center, gave some useful advice on organizing a child's workplace and preventing diseases.
The weight of the backpack should not exceed 10-15% of the child's weight. In order to distribute the load on the spine evenly, choose a backpack with a tight back with a soft lining that fits well to the back. Make sure that the backpack does not fall below the lower back. The ideal option would be a model with a belt fastened at the waist.
The child's chair and table, at which he does his homework, must be selected according to height. The child should easily reach with both legs to the floor or a special support and sit so that the angle between the torso and thigh, as well as between the lower leg and thigh, is 90 °. It is desirable that the table top tilt angle is regulated.
Don't forget to choose the right spot for your table! It is best to do your homework where it is light, but not in front of a window, so that the sun glare does not fall into your eyes. If the child is right-handed, the light should fall on the left, if the child is left-handed, on the right. However, try to keep the whole room evenly lit. Please note that halogen or fluorescent lighting is harmful to the eyes.
Before your child starts working at the computer or watching TV, check the room lighting. Eyes get tired much more in the dark! In addition, it is important to maintain a distance: the distance from the eyes to the monitor should be at least 50-70 cm, to the TV - three times the size of its diagonal and be at least 3 m.
Do not forget that the best prevention of posture disorders is daily exercise and muscle strengthening back. In addition, daily exercise and outdoor exercise are beneficial for your child's overall health.
