Allergy Awareness Week runs from 23- 29 April 2018 and there have been various reports of left-handers being more susceptible to allergies. Stanley Coren in his book Left-Hander reports a study in Glasgow, Scotland where lefthanders were found to be eleven times more likely than righ-handers to suffer from hay fever, asthma and eczema.
Another study at St. Mary's Hospital allergy clinic in London found that patients were 70% more likely to be left-handed than right-handed.
Some research has found an increase in childhood allergies among left-handers and the report we found in the New York Times from back in 1983 also related left-handedness to stuttering, food allergies in hyperactive children and immune diseases among children with autism. The link between left-handedness and childhood allergies in particular was supported by a full review of the literature, reported here.
