From a scientific point of view, is bask in the quilt really good?

Bask in the quilt is very necessary. If you put your quilt in a bedroom without sunshine, slowly, there will be bacteria on the quilt and it will get wet, which is very bad for our health. Bask in the quilt can sterilize the ultraviolet rays in the sun and keep the quilt warm. At the same time, it can also kill the floating dust adsorbed on the quilt.
