How Does Mould Cause Allergies?
Moulds are miniature fungi that cause allergies by releasing tiny, lightweight “seeds”, called spores, into the air. Outdoor moulds live in the soil, and in damp or decaying vegetation.
Outdoor mould spores begin to appear after a spring thaw and reach their peak in summer and early autumn.
What increases your exposure to mould outdoors?
- Cutting grass
- Raking dead leaves
- Working with hay or mulch piles
- Kicking mushrooms (which have many spores under their "caps")
