Researchers from Germany and Switzerland have recently investigated the possible associations between conditions relating to mental health, such as depression and anxiety, and the presence of different types of allergy. Their findings, they say, should prompt scientists to pay more attention to these links.
According to data from the Centers for Disease Control and Prevention (CDC), “allergies are the sixth leading cause of chronic illness in the [United States],” leading to healthcare costs in excess of $18 billion each year.
Moreover, the CDC note that more than 50 million people in the U.S. have an allergy. Across Europe, about 150 million people have an allergy, according to the European Academy of Allergy and Clinical Immunology.
