Allergies can worsen at night due to a combination of factors. One reason is the increased presence of allergens in our bedrooms, such as dust mites, pet dander, and mold. These allergens accumulate in bedding, pillows, and carpets, making it difficult to avoid exposure while sleeping. Additionally, certain types of pollen, like grass pollen, are released at night, leading to higher pollen counts during these hours.
Another contributing factor is our circadian rhythm, which regulates our sleep-wake cycle. As we lie down, our bodies naturally release histamine, a chemical associated with allergy symptoms. This can worsen symptoms, even if allergen exposure is low.
Furthermore, lying down can concentrate allergens in the nasal passages, making them more likely to trigger a reaction. Lastly, using a humidifier can worsen allergies by creating a favorable environment for mold growth, especially if the humidifier isn't properly cleaned and maintained.
To manage nighttime allergies, it is crucial to reduce allergen exposure by washing bedding regularly in hot water, using hypoallergenic pillows and mattress covers, and keeping pets out of the bedroom. Investing in an air purifier can also help remove airborne allergens from the air. Over-the-counter antihistamines may help manage symptoms, but it's best to consult a doctor for personalized advice and treatment options.
