The prevalence of allergic respiratory diseases, such as allergic rhinitis (AR), has dramatically increased worldwide with global warming being a significant contributing factor. AR causes severe disruptions to one’s quality of life, sleep, and productivity. Nearly 1 in 4 Canadians have allergic rhinitis (e.g. hay fever) and up to 78% of individuals in specific work environments develop occupational rhinitis with the primary treatment strategy being over-the-counter anti-histamine medications.
