Pollen and Hay Fever in Centennial, CO
Living in Centennial, Colorado, one is graced with the beauty of changing seasons, but with these transitions, the types and prevalence of pollen also shift, bringing about allergy symptoms for many residents.
As spring begins, the most common allergen is tree pollen. A variety of trees start releasing pollen as early as late December or early January, with the bulk of the season kicking off in February. This early start means some individuals may begin to experience spring allergy symptoms - itchy eyes, runny nose, and nasal congestion - before they even realize that spring is on the horizon. The tree pollen season usually comes to a close in April or May.
When summer arrives, the main allergen shifts from tree pollen to grass pollen. The grass pollen season typically begins in May and can extend through August or sometimes even into early September.
As summer fades into autumn, weeds such as ragweed, tumbleweed, and sage become the primary contributors to the pollen count. This period starts in late summer and continues until the first frost, which can occur as late as mid-December in some years.
Winter might seem like a reprieve from pollen allergies, with the frequent snowfalls and cold temperatures. However, this season brings its unique challenges. The cold weather prompts us to keep our doors and windows closed and pets inside. For those with pet allergies, this can lead to an increase in symptoms. Moreover, heating our homes can lead to drier air, which can irritate sinuses and airways and potentially lead to eczema flares.
In Centennial, the changing seasons come with a variety of allergens. Understanding when different types of pollen are prevalent can help residents prepare for and navigate each season.
