How Often Should You Really Wash Your Sheets?
Becnel says that besides the appeal of having clean sheets to start the week off right, there is so much on our sheets that we can't see with the naked eye.
UC Santa Barbara says that people lose about 500 million skin cells a day. Since we spend about a quarter of the day sleeping, that's a lot of skin cells that end up on our sheets.
Murphy says that the oils, lotions, and creams we use before bed can get into our sheets and pillowcases.
"Also, you might not realise how much sweat, saliva, pet hair, and dust can build up on your sheets in a week. Wash your sheets every week to avoid getting a stuffy nose.
This is especially important if you've spent a lot of money on a luxury brand that you want to last for many years.
Another reason to wash your sheets and pillowcases every week is that dirt and dead skin cells that build up on them get into the cotton fibres and cause the cotton thread to break down.
Murphy also says that people should wash their sheets properly, making sure that all the detergent gets out of the sheets during the wash cycle.
