Nearly half of all Americans are in line for a heavy dose of allergens as
they settle down for a good night’s sleep. The National Allergen Survey of 831
homes across the US, conducted by the National Institute of Environmental 91ɫÇéƬ
Sciences, found that the bedding in over 45 per cent of them contained at least
two micrograms of dust-mite allergen per gram—enough to cause allergies to
develop. “We’re surprised at the prevalence,” says Patrick Vojta of the NIEHS.
He told the American Lung Association this week that more than 23 per cent of
homes have dust-mite allergen levels of 10 micrograms per gram—enough to
cause asthma symptoms.
