Nice fluffy pillow.
Nice fluffy pillow of death.
Seems that pillows are hotbeds of stuff. Nasty stuff. Stuff that you and I don't really want to breathe but are anyway. There's a beautiful little ecosystem of fungi, mites, bacteria and other things that we feed every evening with our hair, skin and drool. Asthmatics and allergy sufferers are particularly at risk from this but we probably didn't expect this to be deadly:
Aspergillus fumigatus, the species most commonly found in the pillows, is most likely to cause disease; and the resulting condition Aspergillosis has become the leading infectious cause of death in leukaemia and bone marrow transplant patients.
