According to a recent study conducted by the researchers at the Imperial College London it was found that lab workers suffer from fewer allergic responses than the others.
It was believed that early exposure to certain animals prevent asthma and allergies. It was found that lab workers who frequently handled research rodents had fewer allergic reactions to the animals. Early exposure to dogs appeared to be protective against eczema allergy. The study results are published in the American Journal of Respiratory and Critical Care Medicine.
It supports the hygiene hypothesis of asthma and allergic diseases. This hypothesis says that naturally occurring infections and microbes might essentially develop immunity against the development of asthma and allergies. Dr Meinir Jones and her team after a study said that they found that laboratory workers developed a natural immunity via exposure to animals through their occupation.
