A recent study claims that hand-washing dishes can prevent   children from having allergies, eczema, and asthma. 
Swedish doctor Bill Hesselmar and his   team conducted the study to determine the relationship between household   practices, like dishwashing methods, and the development of allergies,   eczema, and asthma. The team surveyed   the parents and guardians of 1,029 Swedish children.  
The survey asked about cases of   asthma, eczema, and allergies among the children. It also asked about the   eating habits of the participants, which included how they wash their dishes.    
The team found that families who   machine-wash their dishes are more likely to have allergies. In fact, around   12.2% of the children from families who machine-wash their dishes had   allergies. On the other hand, only 10.3% of the children whose families   hand-wash their dishes showed the same history.    
Results also showed that among   children in families who hand-wash their dishes, 23% had eczema, while 1.7%   had asthma. Among children whose families machine-wash their dishes, 38% had   eczema and 7.3% had asthma. 
Results of this study support the “hygiene hypothesis.” This hypothesis   states that early exposure to allergens and germs can improve the body’s immune system, making a person less   likely to develop allergies. This is because being exposed to germs early on   allows the immune system to identify which substances are harmful and which   are not. A very clean and allergen-free environment in early life, on the   other hand, makes a person more susceptible   to allergies.
