A freshman in high school, it s cold and doesn t want to study at a desk, so sit on the bed to warm

Not good! It's not good ...

The radiation of table lamps has a certain effect, whether it is fluorescent lamps or incandescent lamps, the light is strobic, and sometimes it cannot be observed by the naked eye, but it is very different from natural light. ”

The light source of the table lamp and the eyes should be kept at a certain height, and it is best to use LED lamps because the previous table lamps, the previous lamps are harmful to the human body, and they will have headaches and uncomfortable eyes after a long time, that is because the eye protection table lamp increases the flash frequency in order to solve the problem of strobes, so that the human eye can not feel the flash frequency and the radiation is also increased

Of course, if you don't care about your classmates, sitting on the bed and reading will weaken the light, which is not good for your eyes. Although I enjoyed doing this, the consequence was that I went from not being short-sighted to being short-sighted. I advise you to think again!

It should be fine for the eyes, but it is not good for the cervical and lumbar spine for a long time.
