SPOTTING ALLERGENS AROUND YOU
Allergens are a part of our lives. But if you know what to look for, you’ll be better prepared to steer clear where you can.
Trees are the first plants to produce pollen each spring. Depending on where you live, tree pollen season can start in late winter or early spring.2
In the fall, piles of rotting leaves provide ideal conditions for mould to thrive. Leaf mould goes dormant in the winter but resumes growing as soon as the weather gets warmer.3
Grass pollen is released from late spring through early summer and, because grasses are so widely grown, they’re responsible for a lot of nasal allergy symptoms.
Extreme humidity, flooding, or other types of water damage spur black mould growth. It tends to grow on building materials like fiberboard and on paper, dust, and lint.4,5
It’s actually the waste products of dust mites (microscopic bugs that feed on the tiny flakes of human skin) that circulate as part of household dust and trigger allergic reactions.6
Cat and dog dander (microscopic bits of skin and saliva) is the most problematic among pet-related allergy triggers.
