Correct your posture whenever you're sitting in front of the desk or dining table.
People these days tend to sit down on their chairs for a long time, regardless of the places, including schools, offices, or their homes. What matters are the kind of chairs and desks, and the posture styles people keep while sitting down. In terms of the chairs, it is recommended to have a chair that has a 45 to 50cm width and has an adequate curve that allows the hips to sink down slightly. The back of the chair should be close to the shoulder blades, and should have a proper curve as well. When people are studying or reading books while sitting down in front of the chair, they need to keep the distance between their eyes and the book for about 30~40cm. In addition, since it is not recommended to keep the same posture for an extended period of time, it is highly recommended to get up and walk around or stretch big while sitting down every hour.
