Why Your Allergies Worsen at Night and How to Identify Relief

If you struggle with allergies, you grasp the symptoms can fluctuate throughout the day. For many, these symptoms intensify at night, disrupting sleep and impacting overall well-being. Understanding why this happens and implementing simple strategies can significantly improve your nighttime allergy experience.

Why Are My Allergies Worse at Night?

Allergies often worsen at night due to a combination of factors. Throughout the day, you’re typically exposed to allergens like pollen, dust mites and pet dander. This exposure accumulates, and as the day progresses, your body’s reaction to these allergens can intensify. As Sandra Hong, MD, an immunologist at Cleveland Clinic, explains, “During the day, we are usually inside… but when you depart your office you come face to face with allergens.”¹

when you lie down, mucus accumulated in your sinuses can drain into the throat – a phenomenon known as postnasal drip. This can cause a sore throat, cough, sneezing, and nasal obstruction, making it harder to fall asleep and stay asleep.¹

Simple Steps to Minimize Nighttime Allergy Symptoms

Fortunately, several simple routines can help minimize the impact of allergies at night:

• Keep Windows Closed: Preventing pollen and other airborne allergens from entering your bedroom is crucial.¹
• Shower Before Bed: Washing removes allergen residues from your skin and hair. If washing your hair isn’t possible, covering it at bedtime is advisable, as allergens can transfer to your pillowcase and irritate your face and eyes.¹
• Wash Your Face: Removing pollen from your face, eyelashes, and eyebrows before bed prevents it from entering your eyes and causing further irritation.¹
• Saline Nasal Rinse: Rinsing your nose with a saline solution before sleep can clear your airways and reduce postnasal drip.¹
• Elevate Your Head: Using an extra pillow or adjusting your headboard can help prevent mucus from settling in your throat.¹
• Keep Pets Out of the Bedroom: Pets can carry hair, dander, and pollen, exacerbating allergy symptoms.¹
• Wash Bedding Regularly: Wash your bedding weekly in hot water and use hypoallergenic covers to prevent allergen buildup. Avoid drying sheets or blankets outdoors.¹
• Consider an Air Purifier: Using a humidifier or air purifier can improve indoor air quality, especially in dry environments.¹

When to Seek Professional Help

If your allergy symptoms persist despite these measures and continue to disrupt your sleep, it’s critical to consult an allergist or healthcare professional. They can identify your specific allergens and develop a personalized treatment plan. A professional diagnosis can lead to effective management and improved sleep and overall health.¹
