Stacey Solomon has recently made headlines as she said in a podcast that you should wash your bedding once a week, which was a shock to some people. Many took to Twitter to say whether they agree with what Solomon said or not.
And the debate has prompted experts to have their say on pyjamas. Pyjamas are different to garments that we wash after every use like underwear and socks, so it can sometimes be hard to know when the right time to wash them is.
A spokesman for women's luxury loungewear experts Pretty You London said: "Pyjamas are the only intimate clothing we wear on a regular basis, with many people wearing them as the only layer and without underwear beneath. This closeness to our skin and other parts of our bodies for 6 to 8 hours per night under bedding makes them an ideal breeding ground for bacteria and other germs.
"There really is no one rule that fits everyone with situations like this. But in our opinion, we believe that if you are wearing pyjamas to sleep in then it is acceptable to wear them for 3-4 nights before needing to wash them.
"If you are only putting your pyjamas on after getting in the shower or a bath before going to bed then you may be able to wear them for 5-7 days before needing to wash them."
"If you wear different sets of pyjamas for different parts of the day and for only short periods of time then it really comes down to a judgement call of when you should be washing them, but we would always advise as a good rule of thumb is once per week."
Pretty You London has put together questions to ask yourself to determine how often you should wash your pyjamas:
How often do you wear them?
"If you are the kind of person that only wears a certain set of pyjamas and a different set of pyjamas for sleeping then it is likely that you can go longer without washing them. Alternatively, you wear them if you work from home or change into them once the evening hits."
Do you sweat a lot?
"If you are prone to sweating then it’s likely that you may need to wash your pyjamas longer than others. As well as this, consider how much contact you have from your skin to the pyjama if you are sweating as that will impact how often you need to wash them as well."
Do you plan on wearing them to bed?
"If you choose to wear the same pair of pyjamas that you are relaxing in through the evening and then wearing them to bed you will need to wash them after every use as it's very likely there will be naturally occurring body oils, perspiration and bacteria beginning to build up."
Do you work from home?
"If you work from home regularly, there is a high chance that you choose to wear loungewear/ pyjamas as your outfit of choice throughout the day as you are wanting to remain comfortable - and getting out of the clothes that you went to sleep in helps differentiate your day. If this is the case, then we would recommend 3-4 wears before needing to wash them if you are wearing them on average 7-8 hours during the working day."
