Many factors can impact the intensity of respiratory allergy symptoms. In particular, they will greatly depend on individual, as well as environmental factors.
The evolution of your symptoms usually includes a progression phase that will intensify more or less according to your degree of sensitivity. It is thus possible that a pollen allergy can become more severe from one summer to the next. Furthermore, an increase in outdoor activity, whether it be work-related or recreational, can also affect the severity of symptoms.
Normal variations in outdoor pollen levels, which fluctuate according to climate conditions, can lead to heightened symptoms when the summer is hotter than usual. The same increase occurs when you continue to expose yourself to an animal that you are already allergic to.
Antihistamine-type medications can be effective when nose or eye symptoms are moderately intense. To control more severe symptoms, particularly those related to nasal congestion, it may be necessary to try other types of prescribed treatment.
A good understanding of the factors that influence the intensity of symptoms can contribute to more effective management of allergic reactions.
