Kussens kunnen veel ziektekiemen bevatten*
Een derde van het gewicht van je kussen kan bestaan uit beestjes, dode huidcellen, huisstofmijt en hun uitwerpselen, ontdekten onderzoekers. Hierdoor kun je tal van gevaarlijke ziekten oplopen.
Kussens en de onfrisse lucht in slaapkamers zijn de ideale broeihaard voor bacteriën als MRSA (Methicilline Resistente Staphylococcus Aureus), clostridium difficile (ook gekend als C. difficile) en kunnen zelfs ziekten als de griep,
waterpokken en lepra veroorzaken. Hoewel sommige van deze bacteriën enkel in ziekenhuizen of tropische klimaten te vinden zijn, zullen anderen zich in je bed nestelen, waarschuwt professor Arthur Tucker. Hij bestudeerde de staat van honderden kussens in Britse ziekenhuizen. Daaruit blijkt dat er op de buitenkant van kussens heel wat beestjes leven. In sommige gevallen kunnen de bacteriën door scheuren in de vulling terecht komen. Sommige exemplaren waren besmet met de E. coli, anderen bevatten beestjes die ademhalingswegen- en blaasontstekingen kunnen veroorzaken. Op veel ziekenhuiskussens zaten meer dan een miljoen stafylokokken per millimeter, deze kunnen ernstige infecties bij mensen met een zwak immuunsysteem veroorzaken. Maar het probleem blijft niet beperkt tot ziekenhuizen. Bacteriën voeden zich met dode huidcellen op je kussen, veel mensen wassen dit namelijk nooit. Het is niet genoeg om een schone kussensloop aan te brengen om de hygiëne te garanderen. De hoes ruikt misschien fris en aangenaam, maar je pakt eigenlijk gewoon iets ergs smerig in. Experts raden aan je kussen iedere 3 maanden te wassen. Patiënten met een allergie opteren best voor een synthetisch kussen boven een exemplaar met veren, ook kies je best voor een antiallergene hoes. Je doodt de beestjes op 60 graden, gebruik slechts een kleine hoeveelheid zeep en spoel twee keer.
How your pillow is the perfect breeding ground for gruesome array of pests and diseases
It is not a thought conducive to a good night’s sleep: Up to a third of the weight of your pillow could be made up of bugs, dead skin, dust mites and their faeces.
Pillows – and the stuffy bedroom air that surrounds them – are ideal breeding grounds for undesirables ranging from the superbugs MRSA and C.diff to flu, chicken pox and even leprosy, scientists said yesterday.
While some of the bugs will only be found lurking in hospitals or in tropical climes, others will be making themselves at home in the comfort of your bed, Dr Arthur Tucker warned.
He spoke out after studying the ‘health’ of hundreds of pillows used by patients in hospitals run by Barts and the London NHS Trust.
The tests revealed high levels of ‘living’ contamination on the outside of the pillows. In some cases, rips and tears meant that the germs had found their way into the filling. Some pillows were contaminated with the E.coli stomach bug. Others contained germs that can cause respiratory and urinary tract infections.
Many hospital-issue pillows had more than one million Staphylococcus hominus per millilitre – the bug can cause severe infections in people with weakened immune systems. Dr Tucker described the level as a ‘bio-hazard’. He said: ‘The presence of these bugs means that they can and will be passed to patients.’
Dr Tucker, principal clinical scientist at Barts’ vascular unit, compared the bugs growing on and in standard hospital pillows with those found in anti-bacterial versions.
PILLOW TALK
Allergy sufferers should opt for synthetic pillows over feather ones and fit them with anti-allergen covers.
Kill mites by washing pillows regularly at 60C or putting them in the freezer for 24 hours.
Good Housekeeping recommends washing your pillows once every three months on a delicate cycle.
Wash two pillows together to balance the machine and use only a small amount of detergent. Rinse them twice.
On a hot sunny day, try hanging your pillows outside to dry. Bacteria and fungi like moist environments.
GH's Kathleen Hudley also has a good tip to work out if your pillow needs replacing.
Fold it in half, place a book on top and let go. If the pillow throws off the item and fluffs back to shape, it's still sleepworthy.
He found SleepAngel pillows, made by the Irish firm Gabriel Scientific, were less likely to be contaminated on the surface than the standard NHS ones – and none tested positive for germs inside.
But the problem of bugs in pillows is not confined to hospitals. Dr Tucker warned that up to a third of the weight of your pillow could be made up of bugs, dead skin and house dust mites and their faeces.
Bacteria feast on these and multiply on and inside the pillows – some of which will never be washed.
Duncan Bain, technical director of Gabriel Scientific, said: ‘If you had to come up with a medium to cultivate bacteria, besides a Petri dish with agar [a gelatinous food], a pillow is pretty much as good as you can get.
‘It is a wet sponge that absorbs bodily fluids of various kinds providing nutrients. It is kept at the ideal temperature by the warm body lying on top.’
David Woolfson, the firm’s co-founder, said: ‘It is not just a problem for hospitals. It is an issue for anyone who wants to get a good night’s sleep.’
Dr Tucker warned that simply popping on a clean pillow case is not enough. ‘People put a clean pillow case on and it looks and smells nice and fresh but you are wrapping up something really nasty underneath,’ he said.
But leading bacteriologist Professor Hugh Pennington urged people not to worry about their pillows – pointing out that they will simply contain the bugs they have already.
He added: ‘There is plenty of opportunity to spread bugs partner to partner without pillows.’
For those who can’t afford new pillows, experts recommend putting synthetic and down pillows in the washing machine once every one to three months.
