Are you talking about the gauze curtain like a mosquito net on the bed? If it is, it will be beneficial, because when people sleep, their body functions are recuperating, and their external defense functions will decline, that is, their bodies will be weak. At this time, the pressure of the gas field in the space will have an impact on people, so if you live in a relatively large bedroom, it is best to hang up the bed curtain, especially for children. First, don't live in a big house, children will be unbearable, and it is best to have a bed curtain to block the pressure of the gas field. We see that ancient beds have their own roofs and curtains, forming a small space, which is the reason.
I hope it helps you.
