Moms be careful: A too-clean house is bad for babies
More specifically, exposure to cat dander and a wide variety of bacteria when your baby is under the age of one can help reduce the risk of developing asthma and allergies later in life.
Children who weren’t exposed to a wide variety of pathogens early on were three times more likely to experience difficulty in breathing, compared to those who grew up in dirtier households.
“It was the opposite of what we expected. We are not promoting bringing rodents and cockroaches into the home, but this data does suggest that being too clean may not be good”, says Dr. Robert Wood, chief of the division of allergy and immunology at the Johns Hopkins Children’s Center and co-author of the study.
The researchers suggest that exposure to dust gives the immune system of children something real to fight against. So, if your baby’s pacifier falls on the floor do not rush to wash it! You probably shouldn’t worry too much!
