A survey conducted by Swedish researchers found that in households with a dishwasher, children are much more likely to develop allergies. Another research has found that in more than 62 percent of household dishwasher there are disease-causing fungi. Both of these studies have one thing in common: proving that there are health concerns related to dishwashers. Let’s find out more in the article below.

Allergies may be related to how you wash the dishes

There has been an increase in the frequency of patients presenting with problems of hypersensitivity and respiratory allergies. The dishwasher is handy because it removes all bacteria and brings out our plates and cutlery cleaner than ever. However, Swedish researchers have discovered that children from families that wash the dishes by hand have a 40% lower risk of developing allergies compared to those living in a family where the dishwasher washes them regularly. When you wash the dishes by hand, we leave some bacteria on the dishes. By reusing these dishes cleaned by hand, our body learns to tolerate its environment and get used to the bacteria. On the other hand, if you take a look at some of the dishwashers analyzed on www.dishwashercritic.com, you will see that most of them are designed to eliminate germs and bacteria; some even feature sanitizing features.

According to the assumptions of the previously mentioned study, small children are not sufficiently exposed to infectious agents, microorganisms or parasites. As a result, they are more likely to succumb to allergies because their immune system is not stimulated enough and therefore not able to defend themselves. If you are exposed to germs, especially early in life, you stimulate the immune system in different ways making it more tolerant.

To reach these conclusions, the researchers analyzed the health of 1,029 children between seven and eight years and habits of their parents. 12% were washing the dishes by hand, 84% used a dishwasher. In the past, 38% of children suffered from eczema and 7% had asthma.

Disease-causing fungi lurking in the dishwasher

A recent research has shown that there are dangerous fungi found in 62% of dishwashers all around the world. Damp areas like dishwashers and refrigerators provide the perfect environment for fungi development. Fungi can survive even under extreme conditions; they have a high tolerance to detergents, cold or high temperatures. Fungi send microscopic spores into the air which can be inhaled into the lungs. This is dangerous because they colonize and cause systemic infections that are hard to recover from. Children and diabetic are extremely vulnerable to fungal infections.The researchers have found that the rubber seals of dishwasher doors are the perfect habitat for black yeasts. These heat-loving black yeasts grow in habitats with high concentrations of salt, an ingredient that we also found in dishwasher soap.
