I don’t see anything like this in Japanese universities, which seems strange to me. In Australian and British universities there is information for students on how to stay healthy whilst using a computer. If you don’t follow some basic rules, you can seriously injure your body. Problems can include eye strain, weakening of vision, back strain, spine compression, repetitive strain injury to hands and wrists. Also, bending forward crunches up your digestive organs causing other problems. You need to have a maximum of 30 minutes of computer use, and then take a 5 minute break, including standing up, walk around, and refocusing your eyes on distant objects.
