The primary impact of high pollen levels is on individuals with seasonal allergies, who may experience poor sleep quality and daytime fatigue. Nasal congestion not only disrupts sleep but can also lead to secondary health issues such as reduced oxygen intake and increased stress on the respiratory system. Those with pre-existing respiratory conditions, such as asthma, may face heightened risks during peak allergy seasons. Additionally, the prolonged allergy season caused by climate change could lead to more widespread and persistent health challenges for affected populations.
