Hand washing can reduce the risk of allergic children

Washing can affect the probability of a child allergic to it? Sweden, a new study shows that the answer is yes. Swedish researchers found that those families of children suffering from hand washing allergies, asthma, eczema chance of significantly lower than children with a dishwasher at home.

From the University of Gothenburg, Sweden, pediatric allergy research team in Sweden 1029 families of children were follow-up study, researchers surveyed parents washing habits, and children (most 8-year-old) whether eczema, hay fever, allergic asthma and other health problems. The study found the chance of washing dishes by hand allergic families with children 40% lower than using the dishwasher for families with children.

Health experts believe that the study "hygiene hypothesis" (hygiene hypothesis) provides reliable evidence that excessive clean environment children grow up more allergies and other immune system problems prone to. According to the hygiene hypothesis, if a child growing up in ultra-clean environment, he would never have immunity against bacteria and germs, so once they are exposure to allergens, the body will have an allergic reaction when. Through outdoor activity and those with pets and contact with a small amount of dust and bacteria child, but a stronger immune systems than those who had never come into contact with children bacteria.
Even very carefully cleaned the dishes, and dishwasher compared will leave more bacteria or food residue, which would have been sufficient to enhance the child's immune system to prevent allergies.

See here, whether you want to abandon the dishwasher out? But before you abandon your dishwasher, there are several factors to consider, the new study did not consider the economic situation of the participants and their parents allergies, but researchers have noticed, there are many other reasons children may cause allergies, such as the number of hand-washing families with children living in rural areas.

Prior studies have shown that children who grow up in rural areas, and often participate in outdoor activities is not easy to produce allergic children. In fact, whether regular contact with pets, or if often eat native purchased from rural areas, will also affect the incidence of allergies.
The researchers said they did not want to influence people in this study dishwashing way, but whether if you are hesitant to buy a dishwasher, but just another children's allergies and eczema worried problem, which may be a good reason to save money.
