Why Are My Allergies Worse at Night? A Complete Guide

Common allergy Symptoms

Common symptoms of environmental allergies, according to the Asthma and Allergy Foundation of America, include:

1. Sneezing
2. Runny or stuffy nose
3. Itchy or watery eyes
4. Itchy throat or ears
5. Postnasal drip
6. Fatigue
7. Coughing
8. Wheezing (more common in people with asthma)
9. Headache
10. Dark circles under the eyes (known as allergic shiners)
11. Impaired sense of smell or taste

Sometimes, allergy symptoms are similar to symptoms of a head cold. The best way to tell the difference is to check if you have a fever or body aches, and if you have been exposed to anyone who knows they're sick. Additionally, cold symptoms will get better after a few days, whereas allergy symptoms will usually continue for several days, weeks, or months depending on what you are allergic to.

What Causes Night Allergies?

Night allergies can be caused by a variety of allergens that tend to be more concentrated or active during nighttime hours, according to the AAFA. They report that dust mites (microscopic insects that thrive in warm and humid environments) are a common trigger for nighttime allergies. Their presence in bedding, pillows, and mattresses can lead to increased exposure when lying down to sleep. Similarly, pet dander, consisting of tiny flecks of skin shed by cats, dogs, and other animals, can accumulate in indoor spaces, especially bedrooms, and worsen allergy symptoms at night.

Additionally, the AAFA explains that pollen allergies can also contribute to nighttime allergies, as certain plants release their pollen in the early morning or late evening, leading to higher nocturnal pollen counts

Mold, which thrives in damp and poorly ventilated areas, can exacerbate allergies at night when its spores become airborne, according to the AAFA. They also note that cockroach droppings (a common indoor allergen) can trigger allergic reactions, particularly in urban areas, and may worsen symptoms during the night when people are indoors and near these allergens. Understanding your specific triggers for nighttime allergies is important for managing your symptoms.

How Do You Minimize Nighttime Allergies?

The AAFA recommends the following tips for minimizing your nighttime allergy symptoms:

• Adjust your sleeping position to keep your airways clear
• Use allergen-proof covers on your mattress and pillows
• Wash your bedding weekly in hot water
• Shower before getting into bed to remove pollen from your body and hair
• Use central air conditioning or an air filter to reduce indoor allergens
• Wipe off or bathe your pets regularly to reduce pet dander

What can help relieve nighttime allergies?

To quickly relieve allergy symptoms, you can consider the following tips from Healthline:

• Antihistamines such as loratadine, cetirizine, or fexofenadine can help alleviate symptoms like sneezing, runny nose, and itchy eyes.
• Over-the-counter nasal sprays, such as corticosteroid sprays or saline sprays, can help reduce nasal congestion and inflammation.
• Antihistamine eye drops can provide fast relief for itchy, watery eyes caused by allergies.
• Inhaling steam from a bowl of hot water or taking a hot shower can help clear nasal passages and ease congestion.
• Trying home remedies like local honey, probiotics, and vitamin C can help relieve your allergy symptoms.
• Talking to your doctor about getting allergy shots.

How Do Allergies Impact Your Sleep?

Allergies can significantly impact your sleep by causing symptoms that make it hard to fall or stay asleep, according to the AAFA. Additionally, allergies can exacerbate conditions like asthma, further disrupting sleep patterns. This can all lead to fatigue during the day and reduced overall well-being. Addressing and managing allergies is crucial for improving sleep quality and overall health.

When Should I See My Healthcare Provider?

The AAFA recommends that you consult your healthcare provider if you experience persistent or severe nighttime allergies that significantly disrupt your sleep, impact your daily functioning, or if over-the-counter remedies have been ineffective.

Additionally, if you have underlying conditions such as asthma that are exacerbated by nighttime allergies, seeking medical advice is important for proper management and relief.

For a medical emergency, such as severe allergy symptoms that make it difficult to breath, dial 911 or visit your closest emergency room immediately.
