Roughly one in four U.S. adults and one in five children now live with a diagnosed seasonal allergy — and thanks to longer, more intense pollen seasons, those numbers are climbing. Recent research shows that pollen seasons in North America are starting up to 20 days earlier and lasting longer than in the 1990s, driven largely by rising temperatures and higher atmospheric carbon dioxide levels.
If you’ve noticed your allergies feel worse than they used to — or that they’re dragging on for weeks longer — you’re not imagining it. To understand why, Allergist Dr. Andrey Leonov explains how your allergies affect your sleep and energy levels, and what you can do to minimize symptoms now and throughout the year.
Common Allergy Symptoms That Wear You Down
During an allergy flare-up, you may experience:
- Nasal congestion that makes it hard to breathe through your nose, especially at night.
- Sneezing, coughing, and throat irritation are triggered by inflammation in your airways.
- Itchy, watery eyes and sinus headaches.
- Ear fullness or dizziness from fluid buildup when your ears can’t drain properly.
- Daytime drowsiness and “brain fog” — difficulty concentrating, slower thinking, and low energy.
- Fragmented, low-quality sleep compounds fatigue the next day.
Why Allergies Leave You Exhausted
For many of us, environmental allergens like pollen, mold, and pet dander trigger an allergic response, especially during peak seasons when counts are highest. During an allergic reaction, inflammation develops in your eyes, lungs, sinuses, and throat. That inflammation triggers secondary symptoms — coughing, sneezing, headaches — that keep you from getting a good night’s sleep.
The combination of poor sleep and ongoing congestion is what leads to allergy-induced fatigue. With this understanding, the next step is to identify what’s causing your symptoms and how to address them. The longer symptoms go untreated, the more tired you’ll become — making school, work, and everyday life increasingly difficult.
Identifying Your Triggers
The first step to managing your allergies is identifying which allergen(s) affect you. The American Academy of Allergy, Asthma & Immunology recommends working with a board-certified allergist who can perform skin-prick or blood tests to pinpoint your specific triggers. Once you’ve determined the cause, your allergist can develop a treatment plan to limit exposure and alleviate symptoms.

Ways to Alleviate Allergy Symptoms
Medications
- Non-drowsy antihistamines reduce swelling in your nasal passages and help combat fatigue. Some older antihistamines cause drowsiness, so check the label carefully.
- Intranasal corticosteroid sprays are now considered a first-line treatment for moderate-to-severe allergic rhinitis. For best results, start them 2 – 4 weeks before your typical symptom onset.
- Saline nasal sprays provide gentle, drug-free relief by flushing out allergens and thinning mucus.
Immunotherapy (Long-Term Solutions)
- Allergy shots (subcutaneous immunotherapy) remain one of the most effective treatments for chronic allergies. They gradually build your tolerance to a specific allergen, with long-term benefits that continue even after treatment ends.
- Sublingual immunotherapy (SLIT) tablets are a newer, FDA-approved option for grass, ragweed, tree, and dust mite allergies. They dissolve under the tongue, can be taken at home daily, and are well tolerated with minimal risk of systemic reactions — a great fit for patients who dislike needles or can’t make weekly office visits.
At-Home Relief
- Neti pots and sinus rinses flush allergens out of congested nasal passages. The FDA recommends using only distilled, sterile, or previously boiled water — never tap water.
- Hot showers before bed wash off pollen collected during the day, and the steam opens your nasal passages for better sleep.
- HEPA air filtration in your bedroom can meaningfully reduce indoor allergen exposure overnight. These at-home changes set the stage for broader strategies in allergy-proofing your entire home.
Allergy-Proofing Your Home
- Keep windows closed when allergen levels are high, especially in the morning when pollen levels are highest.
- Vacuum weekly with a HEPA-filter vacuum to pick up trapped pollen, dust, and dander.
- Wash sheets and towels weekly in hot water to kill dust mites.
- Change clothes and shower after spending extended time outdoors.
- Check your local pollen forecast through the National Allergy Bureau before planning outdoor activities.
The Bottom Line
Whether you’re experiencing sleep disturbance, increased congestion, or a combination of the two, allergic brain fog is a real phenomenon — and with allergy seasons getting longer and more intense each year, it’s more important than ever to have a plan. You can get symptom relief and reduce allergy fatigue by working with an allergist to establish a treatment plan tailored to you.

As an allergy, asthma and immunology specialist, I strive to provide my pediatric and adult patients in the Joliet and Lockport communities with the best care possible. Allergies and asthma can have a tremendous impact on your daily life. Whether you’re struggling with chronic sinus symptoms, food allergies or skin rashes, my goal is to work collaboratively with each patient to identify their specific allergens and develop a treatment plan best suited to their individual needs. In order to achieve the best outcomes, it’s essential that patients are included in the decision making process and feel well-informed and comfortable, both with me and their care plan.
