Psychology says people who change their bedsheets every day may be seeking more than just hygiene, they may be cleaning off the stress

For most people, changing bedsheets is a weekly chore. But some individuals prefer to replace their sheets every single day. To outsiders, the habit may seem excessive or unnecessary. To those who do it, however, slipping into freshly washed sheets each night simply feels right. Psychology suggests there may be more behind this routine than a love of cleanliness.

That doesn't mean everyone who changes their bedsheets daily shares the same personality or motivation. Some people sweat more while sleeping, have allergies, own pets, or simply enjoy the feeling of fresh linens. Still, psychologists have identified several theories that help explain why some people develop routines centered on cleanliness, comfort, and predictability.
