I’ve heard it is actually not better to make the bed. If you make it right away the moisture and heat trapped under the covers increases the number of creepy crawly microscopic critters living within your sheets!
Better to peel back your sheets and let the fresh air circulate.
Yeah, I've read that too. That's the reason that housewives in Japan typically hang the futon outside everyday to let the sun kill any and all critters. A bit tougher to do that with a full sized bed.
