As we all know, after a night of contact with the body, quilts often take away a lot of heat, and there will be residual temperature. And some people can't sleep well, and they are likely to drool on the quilt or something. Usually everyone can yell at the saliva on the food. Why not refuse to cover the quilt with your own body fluids?
In short, after a night's sleep, the quilt will contain some water. At this time, we should turn the quilt facing us over and ventilate it to let the residual temperature of the quilt drop. For example, folding the quilt after breakfast is a very time-saving method.
Secondly, why do you want to fold the quilt? Why don't you spread it? It's not impossible, but there will be a lot of dust floating in the air, and the dust received by a flat quilt is definitely much more than that of a folded quilt. I don't want to lie in bed at night, and the quilt covered on my body is dusty, so I can only get up in the morning and fold the quilt.
Finally, folding the quilt is also to prepare for the ventilation where we lie at night. If the quilt is laid flat, isn't it boring to lie at night? Same reason as before, unhealthy.
