Why Should You Regularly Wash Your Bedding?

A survey revealed that almost a quarter (24%) of us wait as long as three-to-four weeks before changing the bed. Our follow-up research suggested this is not wise. For our experiment we asked a willing volunteer to let us monitor their bed over a month under the following conditions: 

  • Sleep in the same bed every night 
  • Never wash or change the bedsheets, pillowcases or duvet cover 

This was the bacteria build up over the month.  

Amongst the samples we found members of the following bacteria were found: 

  • Clostridiales 
  • Bacteroidales 
  • Fusobacteriales 
  • Neisseriales 

These might just sound like scientific jargon that has no real-world meaning, but when we consulted experts, we found just how dangerous they can be.  

Bacteroidetes, for example, can be linked to the following diseases: Appendicitis, Cellulitis and Pneumonia. Aside from the likes of skin ulcers, research sows that Fusobacterium can lead to Lemierre’s syndrome and periodontal diseases. Lastly, Neisseriales has been known to cause diseases like Gonorrhoea and Meningitis. These are extreme cases but shouldn’t be ignored when it comes to your bedding. 

While not washing your sheets often can lead to harmful bacteria, it also means your sharing a bed with rather gross things like sweat, dead skin cells, dust mites and even bed bugs. There could be anything from 100,000 to 10 million of these uninvited guests joining you each night. While they don’t bite, they are considered an allergen and can cause symptoms like hay fever, eczema, asthma and coughing.
