What you may not know is what substances can trigger your nasal allergy symptoms. These triggers are called allergens. Allergens may be present year round, or they may come and go with the seasons. Allergens are generally harmless substances, but to people with allergies, they can trigger bothersome nasal allergy symptoms.
Pollen is a powdery substance given off by weeds, trees, and grasses. If you are allergic to one type of pollen, you may be affected only during a certain season. For example, weeds are pollinated in late summer and fall, trees are pollinated in late winter and spring, and grasses are pollinated in late spring and summer. Pollen allergies can strike at certain times of day. Pollen is often released early in the morning, which results in high pollen counts. Even weather can impact pollen allergies. Warm, dry, breezy days create conditions that allow pollen to move around freely. In contrast, pollen counts are lowest on chilly, wet days. Learn more about the pollen seasons in your area.
Dust mites are so tiny you can't see them without a microscope. They look like small white bugs, and they eat the tiny flakes of skin you shed each day. These flakes are everywhere: in your furniture, bedding, carpets, and even your child's stuffed toys. Learn more about these allergen offenders and how you can get rid of them.
