Nobody likes doing the dishes because doing the dishes is boring.A new study shows that washing dishes by hand is better for children’s health than a dishwasher(洗碗机).

Research in Sweden surveyed the parents of 1,029 children.They found that children whose families hand-washed the dishes had fewer allergies(过敏)than those whose families used to dishwasher to do the dishes.

Earlier research showed that dishes washed by dishwasher are cleaner than those washed by hand .So why would kids who who eat with a little dirtier plates be better at stopping allergies?It says the reason kids have allergies is because their environment are too clean.

Your immune system(免疫系统)keeps you healthy by fighting against(反对)germs(微生物)and viruses(细菌).But when you have allergies,it doesn’t work well and tries to fight common things like usual foods.

“Meeting germs,especially early in life ,is good for the immune system,” says the writer of the study,Dr.Bill in a hospital in Sweden. “You encourage the immune system in different ways and it becomes strong.”

This study shows that while using the dishwasher might be easier,doing more housework with hands ,we have fewer allergies.
