Don't fold the quilt immediately, let it stand for 10- 15 minutes first, because the growth of mites needs moist water between quilts, and when people leave the quilt, the moist water will soon disappear. If the bedding remains intact, moisture and moisture in the outside air will not enter, which will eventually lead to the death of various mites.

So the correct way is to turn the quilt over and open the window after getting up, so that the water and gas can evaporate naturally, instead of folding the wet quilt immediately. Generally, the quilt is opened on the side close to the body and can be folded in an hour or two. Quilts should also be often taken outdoors to dry in the sun, so that the moisture in the inner layer of the quilt will evaporate at high temperature, and the ultraviolet rays in the sun also have the function of sterilization and mite elimination.

Although it is wet on rainy days, the water vapor in the quilt is far more than that in the air, so it is necessary even on rainy days.
