If you’re one of the many people who experience allergies, you may have suffered through common symptoms like itchy eyes and skin, nasal congestion, and/or watery eyes. You may have even found yourself feeling tired—so if you’re wondering if allergies can make you tired, the answer is “yes.”

There are many ways that having allergies can impact your energy levels and cause you to feel tired. In fact, there’s even a name for fatigue caused by allergies—"brain fog”—which can make it difficult to carry out everyday tasks or function at your best.

Read on or skip to our infographic to understand why your allergies may be making you tired and learn tips for combating sleeplessness.


Why Your Allergies Could Be Making You Tired

In the United States, allergies are the sixth leading cause of chronic illness. Allergens can exist both indoors and outdoors, and it can be a challenge to limit your exposure to them. When it comes to indoor and outdoor allergies, there are a few common culprits that can cause seasonal or recurring allergic reactions such as sinus swelling, nasal congestion, watery eyes, and tiredness. The most common triggers include dust mites, mold, pollen, and pet dander – all of which may cause fatigue.

There are several reasons why fatigue can be linked to allergies. First, exposure to an allergen triggers an immune response that’s meant to protect you from foreign invaders. Your immune system produces a chemical called histamine, which can cause symptoms like itchiness, swelling, trouble breathing, and fatigue.

Allergy symptoms such as congestion, coughing, sneezing, and general feelings of discomfort can make it difficult to relax and fall asleep or disrupt your ability to stay asleep, contributing to feelings of fatigue during the day.

Plus, taking medications – such as antihistamines – to combat or prevent allergy symptoms may lead to drowsiness during the day, as well.

Common Triggers for Allergic Reactions


Ways to Prevent Allergy Fatigue

While there is no cure for allergies, there are several things that you can do to manage your symptoms and minimize allergy fatigue.

Find the Source of Your Symptoms

To manage your symptoms, start by finding the source of your allergies. Taking a quick allergy test, which you can do from the comfort of your home, can help you narrow down possible culprits.

Having an allergy log is another great way to figure out what’s causing your symptoms. Recording notes and identifying patterns when you’re experiencing symptoms of fatigue and jotting down what you’ve been exposed to that day is a great way to find the link between an allergen and your symptoms.

Limit Exposure

Once you’ve identified what’s causing your allergy symptoms, it’s recommended that you do your best to eliminate or reduce your exposure to it whenever possible. If you’re suffering from an indoor allergy, there are several easy ways to allergy-proof your home.

For outdoor allergens, like mould and pollen, monitoring the allergen-count and limiting your time outside during high exposure days are great ways to prevent allergy symptoms and fatigue.

Consider Medication

Medication may be effective in reducing or preventing your allergy symptoms. In fact, immunotherapy (allergy shots) is proven to reduce symptoms in about 85% of people with allergies, though you’ll need to discuss this option further with your healthcare provider to determine if it’s an appropriate course of treatment for you.

Additionally, over-the-counter medications that contain antihistamines can be an easy and effective way to manage both year-round and seasonal allergy symptoms. Be sure to ask your healthcare provider or pharmacist which over-the-counter allergy medication would be least likely to make you feel drowsy.

Visit an Allergist

Allergists specialize in allergy symptoms and conditions and are trained to identify the triggers that may be causing a reaction. If your fatigue or other symptoms are chronic and/or severe, are negatively affecting your quality of life, and you’re unable to get to the source, an allergist will likely be able to diagnose and treat the problem.

People with Allergies have trouble Sleeping


Tips for Getting Quality Sleep With Allergies

If your allergies are keeping you up at night or causing fatigue during the day, ensuring you take the proper steps to get quality sleep (~7–9 hours) each night is always a good idea. Below are a few simple tips that can help you get a good night’s sleep to feel rested and alert during the day, even if allergies are a problem.

Take a Shower Before Bed

Taking a shower before bed can help wash pollen or other allergens out of your hair or off your skin, ensuring that you are not bringing allergens into bed with you. Taking a shower or bath before bed may even improve your ability to get a good night’s sleep by lowering your body temperature, which can help you fall asleep and stay asleep. This should help you feel more rested when you wake up the next morning.

Wash Your Sheets Frequently

We spend approximately one-third of our lives in bed, so keeping your sheets clean and allergen-free is especially important if you suffer from allergies. To prevent dust mites from making themselves comfortable in your bedding, wash your sheets in hot water once a week.

Keep Your Head Elevated

If you are congested from allergies, keeping your head elevated by propping it up on a pillow or two can help eliminate congestion in your sinuses. With your head elevated, gravity will help keep excess mucus from building up in your nasal passage.

Consider Removing Pets from the Bedroom

Since pets can shed hair and dander on your mattress, bedding, and carpet, it’s not difficult for this type of allergen to be all over your bedroom. If pet dander is the source of your allergies, consider limiting your pet’s exposure to your bedroom.

Use an Air Purifier

Placing an air purifying device in your bedroom can be a great solution to improve your air quality and allow you to sleep better at night. It helps by removing allergy-causing particles from the air. By removing these allergy triggers, you may find that any sneezing or coughing spells during the night are significantly reduced.

Finding the source of your allergy symptoms, eliminating or reducing exposure, and ensuring you get a good night’s sleep are all ways to help reduce allergy fatigue that may come with year-round or seasonal allergies. Not getting enough sleep, allergy fatigue, or brain fog from allergies can impact your quality of life, so getting to the source of your allergies and finding the best ways to manage them is important.

If you’re unsure about whether your fatigue is from allergies or other factors, consider taking an at-home allergy test or seeing an allergy specialist.
