Study Finds Higher Rates of Allergic Diseases in Families that Use a Dishwasher.

A Recent Article in Pediatrics (February, 2015) Reports Higher Rates of Eczema and Allergic Diseases in Families that Use a Dishwasher.

Hypothesis:  This study’s hypothesis was that microbial exposure in early life reduces the risk of allergic diseases such as eczema and allergies. This study investigated if cleanliness affects the prevalence of allergic diseases.

A questionnaire was used to study 1029 children ages 7 and 8 years old in Sweden. The questionnaire was taken from the International Study of Asthma and Allergies in Childhood Questionnaire.

This study found that hand washing dishes decreased the risk of developing allergic diseases. Risks were also reduced if the family also bought food directly from farms and served fermented foods.

Conclusion: Microbial exposure causes a tolerance to allergens and decreases a risk to allergic diseases.

How can you apply this to your life with children? Being a GERMAPHOBE can be counter productive when raising children. Keeping a clean house is important and using soap and water is important but using disinfectants, antibacterial cleansers, chemicals and creating a sterile environment may affect the immune system negatively.
