Could using a dishwashing machine increase the chances your child will develop allergies? That's what some provocative new research suggests but don't tear out your machine just yet. <\/p>\n
The study involved 1,029 Swedish children (ages 7 or 8) and found that those whose parents said they mostly wash the family's dishes by hand were significantly less likely to develop eczema, and somewhat less likely to develop allergic asthma and hay fever. <\/p>\n
\"I think it is very interesting that with a very common lifestyle factor like dishwashing, we could see effects on allergy development,\" says Dr. Bill Hesselmar of Sweden's University of Gothenburg, who led the study. <\/p>\n
The findings are the latest to support the \"hygiene hypothesis,\" a still-evolving proposition that's been gaining momentum in recent years. The hypothesis basically suggests that people in developed countries are growing up way too clean because of a variety of trends, including the use of hand sanitizers and detergents, and spending too little time around animals. <\/p>\n
As a result, children don't tend to be exposed to as many bacteria and other microorganisms, and maybe that deprives their immune system of the chance to be trained to recognize microbial friend from foe. <\/p>\n
That may make the immune system more likely to misfire and overreact in a way that leads to allergies, eczema and asthma, Hesselmar says. <\/p>\n
He and his colleagues have been trying to figure out some of the simple day-to-day ways we might be too clean. A previous study examined how parents cleaned off their children's pacifiers. In their latest research, the researchers took a look at how people wash their dishes. <\/p>\n
\"The hypothesis was that these different dishwashing methods ... are not equally good in reducing bacteria from eating utensils and so on,\" Hesselmar says. \"So we thought that perhaps hand dishwashing was less effective, so that you are exposed to more bacteria\" in a way that's helpful. <\/p>\n
In a study released Monday in the online version of the journal Pediatrics, the researchers report what they found: In families who said they mostly wash dishes by hand, significantly fewer children had eczema, and somewhat fewer had either asthma or hay fever, compared to kids from families who let machines wash their dishes. <\/p>\n
Other researchers say the new study may be onto something, though it's still too soon to tell. <\/p>\n
