Climate change causing more allergies among Canadians, experts warn
For the last two years, rushing their toddler to hospital has become the norm for Daniela Mora-Fisher and her husband.Julian, now three years old, has been “struggling with respiratory distress since probably he was 18 months,” she said.
Allergies in both children and adults have definitely been on the rise over the last several years, said Dr. Susan Waserman, division director of clinical immunology and allergy at McMaster University in Hamilton, Ont. Research has shown that over the last few decades in North America, “the average pollen season has extended about three weeks and that now plants release about 20 per cent more pollen than they used to,” Lem said.That’s consistent with data gathered by Aerobiology, a Canadian company that monitors airborne allergens such as pollen and mould spores.
“We used to think that pollen allergy wouldn’t make an appearance ’till the age of five or so. I see a lot of environmental allergy a couple of years earlier than that now,” she said.Pollen isn’t the only allergy worsened by climate change, Lem said. “All those different moving parts … are coming together to create this storm of allergies,” Lem said.
But every time they visit her in Toronto, “they cannot stop, like, having rashes and sneezing,” she said.
