Can Allergies Cause Snoring?

Allergies are often associated with sneezing, itchy eyes, and congestion, but for some people, they may also coincide with an increase in snoring. If snoring tends to show up or worsen during allergy season, it might be related to how allergies affect your airways. Here's a look at the possible connection between allergies and snoring, along with tips that could help.

What’s the Link Between Allergies and Snoring?

Allergies may contribute to snoring, particularly when they cause nasal congestion. During an allergic reaction, the body responds to triggers like pollen, dust mites, or pet dander, which can lead to symptoms affecting airflow through the nose. A blocked or stuffy nose can make it harder to breathe through the nose during sleep.

In such cases, people may begin breathing through the mouth, which can increase the chance of snoring. This happens because airflow through the mouth might lead to vibrations in the throat tissues. However, mouth breathing on its own does not always lead to snoring - other factors like sleep position, muscle relaxation, and individual anatomy can also play a role.

Why Nasal Congestion Matters at Night

The nose is typically the preferred breathing route during sleep. But when it's congested or inflamed, airflow may shift to the mouth. This can dry out the throat and potentially contribute to nighttime noise. That said, nasal congestion is just one of several possible contributors to snoring.

Common Allergy Triggers That May Disrupt Sleep

Some allergens are seasonal. Others stick around year-round. Here are a few of the most common ones:

Indoor Triggers

• Dust mites, often found in bedding and carpets

• Pet dander from cats and dogs

• Mold, especially in damp or poorly ventilated rooms

Outdoor Triggers

• Pollen from trees, grasses, and weeds

• Air pollution or smoke

• Seasonal shifts that kick up allergens in the air

When these allergens make their way into the bedroom, they can contribute to nighttime congestion — and, as a result, snoring.

How Allergies Might Affect Sleep Beyond Snoring

Snoring isn’t the only sleep-related issue tied to allergies. Some people also experience:

• Trouble falling or staying asleep

• Restless sleep or frequent waking

• Morning headaches

• Daytime tiredness

Nasal congestion, even if it's temporary, can make it harder to reach deeper stages of sleep, leading to grogginess the next day.

What You Can Do That Might Help

The nose is typically the preferred breathing route during sleep. But when it's congested or inflamed, airflow may shift to the mouth. This can dry out the throat and potentially contribute to nighttime noise. That said, nasal congestion is just one of several possible contributors to snoring.

1. Identify and Reduce Exposure to Allergens

Try to identify what’s triggering your symptoms. Steps like using a HEPA filter air purifier, keeping windows closed on high-pollen days, and washing bedding in hot water weekly may help. Removing heavy drapes or rugs that trap dust and keeping pets out of the bedroom can also make a difference.

2. Improve Bedroom Air Quality

Good air quality may reduce nighttime irritation. Vacuum regularly with a HEPA filter vacuum, consider a dehumidifier in damp spaces, and avoid strong indoor scents like sprays or candles.

3. Practice a Nighttime Allergy Routine

Simple nighttime habits could support easier breathing. Showering before bed can help wash away pollen or pet dander. Changing clothes after being outdoors and using a saline rinse may also help clear nasal passages.

4. Talk to a Healthcare Professional

If allergy symptoms are frequent or affecting sleep, consider discussing them with a healthcare provider. They can offer guidance on identifying triggers and managing ongoing symptoms.

When to Look Into Other Causes

Allergies are one possible contributor to snoring, but they may not be the only one. If snoring is persistent, loud, or comes with symptoms like gasping or excessive daytime tiredness, it might be a good idea to get a sleep evaluation.

Conclusion

Allergies and snoring may be linked for some people, particularly when nasal congestion affects airflow during sleep. While allergies are not the sole cause of snoring, reducing allergen exposure and creating a more breathable sleep environment may help improve comfort at night.

Understanding what's behind nighttime symptoms is a helpful first step. A few simple adjustments around the home might support better rest during allergy season.
