2024 Allergy Season,Pollen And Co2

Allergies are hitting harder and lasting longer as higher temperatures and CO2 allow pollen and weeds to flourish.

Itchy red eyes, noses that can’t stop sneezing and a fear of going outdoors have set in around Denver as allergy season ramps up.“I'm sure you've heard everyone say ‘This is the worst allergy season ever.’ They say that every year — and they are correct every year,” says Bill Anderson, medical director of the allergy immunology section at Children’s Hospital Colorado. “Every year is the worst allergy season.

“What we're seeing is that because of these warmer temperatures, the allergy season is starting earlier each year and lasting a little bit longer,” he says. “Also, during that time period we're having more pollen produced because of increased carbon dioxide in the atmosphere, which leads to increased growth of plants so they produce more pollen.”

“People that are already allergic will likely have worsening symptoms, because a large factor with allergies is just how much you're exposed to the thing that you're allergic to,” Anderson says. “Then, with increased exposures, our bodies can become sensitized and develop allergies.

Even washing your hands when you get home can help, and so can taking shoes off at the door so you don’t track pollen through the house. If the temperature allows, allergy sufferers should keep their windows closed, too, and avoid line-drying clothes outside.
