For those with asthma, 'ever notice if your attacks always coincide when you're lying down on your bed? Here's a clue about the usual suspects.
So bad is the situation that a news report describes your bed as a virtual ecosystem. Yes people, your bed is a forest of creatures you do not see....and I'm not talking of imaginary monsters, ok?
What "forest of creatures" am I talking about?
Most beds are home to thousands of microscopic dust mites, which produce so much excrement they can add a pound or two of weight to your mattress every year, by some estimates. Humans feed the mites by shedding dead skin, and add water from about 100 litres of sweat a year, says Ashley Woodcock, a researcher at the University of Manchester in England.
"We really thought it was the kind of stuff you find on a bathroom wall in a damp house. To find it in the bed you sleep in is really a surprise," said Dr. Woodcock, whose findings are to be published this week in the journal Allergy.
He and his colleagues found up to 16 species of fungi, including types normally found in bread and bathrooms, and a more worrisome species called Aspergillus fumigatus, which is the leading cause of death from infection in patients with leukemia and bone-marrow transplants.
