Does hayfever get worse at night? This is a common question among those who suffer from this seasonal allergy. Hayfever, also known as allergic rhinitis, is characterized by symptoms such as sneezing, runny nose, and itchy eyes. While these symptoms can be bothersome during the day, many hayfever sufferers find that their symptoms intensify at night, making it difficult to get a good night’s sleep.
Hayfever is caused by an allergic reaction to pollen, which is released into the air by grasses, trees, and weeds. During the day, the pollen count is typically higher, leading to more frequent and severe symptoms. However, at night, the pollen count often drops, which might lead one to assume that hayfever symptoms would improve. Unfortunately, this is not always the case.
Several factors can contribute to the worsening of hayfever symptoms at night. One of the primary reasons is the body’s natural circadian rhythm. As the sun sets and darkness falls, the body’s production of melatonin, a hormone that regulates sleep, increases. This increase in melatonin can make the body more sensitive to allergens, leading to an exacerbation of hayfever symptoms.
Another factor is the indoor environment. At night, many people spend more time indoors, where pollen levels are often higher due to closed windows and doors. Additionally, indoor allergens such as dust mites, pet dander, and mold can trigger hayfever symptoms, especially during the cooler, more humid months.
To help alleviate hayfever symptoms at night, there are several strategies that can be employed. First, it’s important to keep windows closed during peak pollen hours, which are typically in the morning and early evening. Using air purifiers or high-efficiency particulate air (HEPA) filters can also help reduce indoor pollen levels.
In addition, taking antihistamines or decongestants before bedtime can help manage symptoms. It’s important to choose a medication that is suitable for nighttime use, as some can cause drowsiness. Furthermore, using nasal corticosteroids can help reduce inflammation and congestion throughout the night.
Lastly, maintaining a clean and dust-free bedroom can significantly reduce the risk of allergic reactions. Regularly washing bedding in hot water, using hypoallergenic pillows and mattress covers, and vacuuming frequently can help minimize exposure to allergens.
In conclusion, while the pollen count may decrease at night, hayfever symptoms can actually worsen due to the body’s circadian rhythm and indoor allergens. By understanding these factors and implementing appropriate strategies, hayfever sufferers can better manage their symptoms and enjoy a more restful night’s sleep.
