According to experts, almost every school student has 2-3 diseases by the end of his or her studies. The fact is that only 10% of children finish school healthy. High study load often causes stress, eyes and stomach problems. Read some recommendations that (would/could/must/can) help stay healthy.
A child receives more than 80% of all the information through sight, so it's very important to train and protect it. The first point to consider is the learning time in front of the computer. It (should not/should/must/can) be over 30-40 minutes. When working with a computer, the distance to the screen should be at least 40 centimetres but no more than 1 metre. One more recommendation deals with light in the room. It should not be reflected from the screen. In addition to that, children (must/would/must not/should) work on the computer in complete darkness. Healthy diet with lots of vitamins and special gymnastics (needs/must/have to/can) also be helpful to keep the eyes healthy.
Another health problem many school students suffer from is called gastritis. It's a stomach disease caused by stress, unhealthy diet and skipping the mealtime. For a healthy stomach, every student (сan/should/should not/cannot) keep a balanced diet, have three meals a day and not be nervous about his or her studies.
A doctor can always help to cure any disease, but it is easier to prevent than to treat.
