Harm of bad sitting posture:
1, learning
First, I can't write well. Incorrect pen holding posture will almost inevitably lead to written words-font skew, distorted shape, scattered structure, weak strokes and so on.
Second, the writing speed is slow. In contrast, the correct capital holding can improve the writing speed by more than 30%-this is a "horrible" value. Horror doesn't mean writing fast. The horror lies in how much precious time children will waste if they don't get the money correctly!
Third, it affects grades, especially composition. As the old saying goes, "A word is like a person." In fact, when a teacher reads a composition, the first thing he looks at is whether the handwriting is good or not, which often determines the final score of the composition.
2. Physical properties
One is myopia. Myopia is a symptom that the eyes can't see clearly, but can see clearly what is near. Under the premise of static refraction, distant objects cannot converge in the retina, but form a focus in front of the retina, thus causing visual distortion and blurring of distant objects.
The second is hunchback. It is not that you will hunch over after sitting for a day, but Dr. Golubic said: "If your muscles are not strong enough for a long time, your bones will be deformed.
But what we know is that when you hunch over, you will send a signal that makes people feel depressed and depressed. He added that when you sit up straight, "people will think that your mental state is better".
