For many hay fever sufferers, nighttime can bring a surge in symptoms, making it challenging to rest and relax. Several factors contribute to this nocturnal agony:
- Pollen Levels: Pollen counts tend to be higher during the early morning and evening hours. As the air cools down in the evening, pollen particles descend closer to the ground, leading to increased exposure for those with open windows or inadequate ventilation.
- Closed Spaces: While it might seem logical to keep windows closed during peak pollen hours, doing so can lead to poor indoor air quality and trapped allergens indoors, especially in poorly ventilated spaces.
- Dust Mites: In addition to pollen, dust mites can trigger hay fever symptoms. Dust mite allergens, commonly found in bedding and upholstery, can become airborne during sleep, causing irritation and congestion.
- Drier Air: Indoor heating during cooler nights can lead to drier air, aggravating nasal passages and making it easier for allergens to enter the respiratory system.
If you’re unsure whether your symptoms are a result of hay fever or a common cold, understanding the differences can be crucial.
