This is how long you should wear your pyjamas before washing them!

Despite spending close to eight hours in them every night, most people aren’t washing their pyjamas enough. So, how often should you wash them and what are you risking if you don’t? By Francesca Menato

From switching between pyjamas in the week, to leaving the laundry to someone else – there are all manner of excuses for not washing your PJs enough – so how long is too long? 

How often should you wash your PJs?

A recent study found that people may be wearing the same pyjamas for as long as two weeks or more! 

As a rule your sleepwear should be washed every week at least.

The sniff test – the most common method of testing cleanliness – is not accurate enough. 50% of men and 41% of women asked, admitted this was how they decided when to put their PJs in the washing machine!


Bacteria can build up in a major way in your pyjamas. The oily build up on your skin is often full of bacteria, which is then transferred to your sleepwear. These can cause infections in cuts, acne or even cystitis.

Similar to your towels, your PJs also pick up a LOT of dead skin cells, especially given how much people move and sweat in their sleep.

Also, to make it worse, leave it too long and the nasties on your PJs will transfer to the other things in the washing machine.

How to wash your PJs

 ‘As with all laundry – read the label,’ says Good Housekeeping UK’s Verity Mann.

For cotton pyjamas be careful of washing higher than 40 degrees in case of shrinking and if they are brushed cotton be aware of any added fibres that may mean they need a more delicate cycle. Flannel for example needs to be treated more like wool.

‘Silky PJs require a more sensitive treatment,’ says Verity, ‘often colours fade more quickly, so if you find you often wear just the trousers, wash the shirt with it to avoid mismatched shades.’
