After a cold, you often feel cold, and some patients have fever, so covering your sweat with a quilt can help relieve the cold, body aches and fever. If you have sweat after a cold, try to wipe with a warm towel, do not sweat after using air conditioners, electric fans, folding fans, etc. to make the sweat clean. This may allow the wind and cold to enter the body again through the opening of pores, making the cold worse, so pay special attention to the process of sweating after covering sweat.
