It’s springtime, which means you can’t wait to step outside and enjoy a few breaths of fresh air. Unfortunately for some of us, that’s when the non-stop cycle of stuffiness begins. Your nose starts to clog up. Itchiness fills your eyes. Every now and then you get a headache, too. Finally, you begin to wonder: Do I have a sinus infection or seasonal allergies?
Finding the answer isn’t easy, but it is possible. Read on and get the details on seasonal allergies in North Idaho, how to tell the difference between a sinus infection and seasonal allergies, and where to find care.
Are allergy seasons in North Idaho getting longer?
Based on national trends, it’s a safe bet that North Idaho allergy seasons are starting earlier and lasting longer than they did previously. Nationwide, pollen counts have increased by 21% over the past quarter-century, according to newly released data from the U.S. Department of Health and Human Services.
Simultaneously, more people are feeling the effects. Seasonal allergies impact 1 in 4 adults and 1 out of every 5 children, says the Asthma and Allergy Foundation of America (AAFA).
The good news for people in the Inland Northwest: North Idaho is not among the top 100 U.S. allergy capitals, a list of the most challenging places to live with seasonal allergies. However, allergic rhinitis (also called hay fever) still happens in our region.
Spring allergies in the Inland Northwest tend to begin in late February or early March. That’s when pine, birch, cottonwood, and elm trees start emitting pollen, which most people recognize as fine, yellow dust covering a car, sidewalk, or backyard deck. By mid-May, grass pollens overtake tree pollens as the top allergy-causing culprits. Once we reach summer, weed pollen begins to kick up, typically starting in mid-July, extending allergy season even further.
Allergic rhinitis (hay fever): causes and symptoms
What you might call “seasonal allergies” is what doctors refer to as allergic rhinitis, also known as hay fever. The condition occurs when the body reacts to pollen, creating an immune response that can create specific symptoms, including:
- Nasal congestion
- Post-nasal drip
- Coughing
- Sneezing
- Clear, runny nasal discharge
- Itchy or watery eyes
- Itchiness in the nose or throat
Sinusitis (sinus infections): causes and symptoms
Unlike hay fever, which develops due to particles in the air, sinusitis (also known as a sinus infection) comes from a viral or bacterial infection. People with higher levels of inflammation in their body may be more susceptible to recurrent sinus infections. Symptoms of sinusitis include:
- Nasal congestion
- Post-nasal drip
- Coughing
- Sneezing
- Thick, yellow or green nasal discharge
- Facial pain or pressure around the forehead, eyes, and cheeks
- Reduced or lost sense of smell
- Fever
Knowing the difference between seasonal allergies and sinus infections
Because there is so much overlap between symptoms, figuring out whether you have seasonal allergies or a sinus infection can be challenging. Three clues to help solve the mystery include:
- Unique symptoms. If you have watery or itchy eyes, you’re likely suffering from seasonal allergies. If you have facial pain, a loss of smell, or a fever, a sinus infection is the most probable cause.
- Timing of symptoms. Do you usually get stuffy when you’re outdoors, and then start to feel better the longer you’re inside? If so, seasonal allergies are most likely to blame.
- Duration of symptoms. Sinus infections typically go away within a week to 10 days, while hay fever symptoms can last for as long as the offending pollens are circulating in the air.
For a definitive diagnosis, always see a medical professional.
How to treat symptoms of hay fever and sinusitis
Some people prefer to treat their symptoms naturally. Saline sprays or neti pots can help moisturize dry nasal passages, and flush out allergens and mucus. Medications that can be effective in treating symptoms of hay fever and sinusitis include:
Antihistamines: Typically used for seasonal allergies, antihistamines like loratadine and cetirizine block histamine, a chemical that the body releases during an allergic reaction. For best results, allergy sufferers should start taking antihistamines about a week prior to the start of allergy season and continue taking them throughout the duration of the season.
Nasal corticosteroids: Nasal sprays like fluticasone and mometasone help relieve nasal congestion and swelling for both seasonal allergies and sinus infections. These medications work best when used consistently, not just when symptoms are bad.
Decongestants: These medications bring short-term relief from sinus pressure or a stuffy nose caused by hay fever or sinusitis. Most are sold in pill form and are available over-the-counter, but some may raise your blood pressure. Nasal spray decongestants like oxymetazoline should be used only for three days in a row at the most to avoid rebound congestion.
Your doctor will advise you on which medications and treatments will work best. It’s wise to consult with a doctor when:
- Your symptoms are worse than during a “normal” allergy season
- You suffer from seasonal allergies and live with asthma
- Over-the-counter medications aren’t helping
- Your symptoms are affecting your quality of life
Tips and tricks to survive spring allergy season
If you or your family member has a history of seasonal allergies, try these tips to reduce your symptoms and limit your exposure to pollen.
Monitor weather forecasts. Watch the daily pollen counts and stay indoors as much as possible on high-pollen days.
Time your outdoor activity. Pollen levels tend to be higher in the early morning and lower in the evening. So, if you usually walk before breakfast, consider switching to an after-dinner stroll during allergy season.
Keep the windows closed. In general, it’s safer for allergy sufferers to turn up the air-conditioning than to open the windows, especially on windier spring days.
Clean your living space. Vacuum and dust inside your house regularly. Use air purifiers with HEPA filters. Change and wash your bedsheets often.
Garden smartly. Wear sunglasses and a hat to shield your eyes and forehead from pollen. Consider wearing a mask over your mouth and nose for added protection.
Wash up after being outside. Take off your shoes, change your clothes, and take a shower to wash off all pollen and avoid carrying it throughout the house.
Choose the right foods. Fruits and leafy green vegetables are high in vitamins and antioxidants, supporting immune health and helping you fight off sinusitis or seasonal allergies.
