A report in The Atlantic covers how one physician discovered the connection between severe allergies and higher rates of anxiety and depression.
In 2016, Nanda and her colleagues published a study that found that among 7-year-olds, allergies were indeed associated with depression, anxiety, and symptoms such as being withdrawn. Kids with hay fever had a threefold risk of depression and anxiety. Recently, more evidence has supported this link—and not just in children. A study of German adults that came out in April also found that generalized anxiety was associated with seasonal allergies.
If further research bolsters this relationship between allergies and mental health, it could provide a fascinating glimpse into how our bodies might influence our minds, and possibly vice versa. Two seemingly unconnected diseases, each affecting millions of Americans, could turn out to be not so different after all.
