Understanding and Coping With Seasonal Allergies

By: Jameson Price Last updated: 04/28/2025

For many people, warmer weather brings more than sunshine and outdoor activities. It can also bring sneezing, itchy eyes, a runny nose, and congestion. Seasonal allergies, also called hay fever or seasonal allergic rhinitis, affect millions of people and can make certain times of the year difficult to enjoy. Seasonal allergies happen when the immune system reacts to substances in the environment that are normally harmless.

Pollen from trees, grasses, and weeds is one of the most common triggers. The good news is that you do not have to simply put up with allergy symptoms. Understanding your triggers and making a few changes can help you feel better during allergy season.

What Causes Seasonal Allergies?

Seasonal allergies are caused by an immune system reaction to allergens, which are substances the body mistakenly treats as harmful. When someone with allergies encounters a trigger such as pollen, the immune system releases chemicals that cause inflammation and other symptoms.

Different plants release pollen at different times of the year. Trees are often major allergy triggers during the spring, while grass pollen can cause problems in late spring and summer. Weeds, including ragweed, are common causes of fall allergies. Mold spores can also trigger seasonal symptoms.

The exact timing depends on where you live and the weather. Warm, dry, and windy conditions can spread pollen through the air, while rain can temporarily clear pollen from the air.

Knowing when your symptoms tend to appear can help you identify possible triggers and prepare before allergy season reaches its worst.

Recognize the Common Symptoms

Seasonal allergies can affect the nose, eyes, throat, and even your energy level.

Common symptoms include:

Sneezing
Runny or stuffy nose
Itchy nose or throat
Watery, red, or itchy eyes
Postnasal drip
Coughing
Fatigue
Dark circles or puffiness around the eyes

These symptoms can be uncomfortable, but they are usually not dangerous. However, allergies can make it harder to sleep, concentrate, exercise, or enjoy outdoor activities.

It is also important to recognize that allergies can look similar to a cold. A cold is caused by a virus, while seasonal allergies are caused by an immune response to allergens. A fever and sore throat are more common with a cold, while itchy eyes are especially common with allergies. Seasonal allergy symptoms can also last for weeks, while a typical cold generally lasts for a shorter period.

Pay Attention to Pollen Counts

One simple way to manage seasonal allergies is to pay attention to pollen levels.

Many weather websites and local news sources provide pollen forecasts. When pollen counts are high, you may want to spend less time outside, particularly if you know that a certain type of pollen triggers your symptoms.

You do not necessarily have to stay indoors all day. Instead, think about choosing better times for outdoor activities. Mayo Clinic recommends avoiding outdoor activities when pollen counts are high and staying indoors on dry, windy days when pollen can spread more easily.

After spending time outside, changing clothes and showering can also help remove pollen from your skin and hair. Keeping windows closed during periods of high pollen can reduce the amount that enters your home.

Small changes like these can reduce your overall exposure without forcing you to completely give up the activities you enjoy.

Keep Pollen Out of Your Home

Your home should provide a break from outdoor allergens, but pollen can easily come inside on clothing, shoes, pets, and through open windows.

During allergy season, keep doors and windows closed when pollen levels are high. Using air conditioning in your home and car can help reduce the need to open windows.

Regular cleaning can also help. Vacuuming floors and cleaning surfaces can remove allergens that have settled inside your home. Mayo Clinic recommends considering a HEPA filter for rooms where you spend a lot of time, especially the bedroom.

If you spend time gardening or mowing the lawn, consider wearing a mask designed to reduce exposure to airborne particles. You can also ask someone else to handle particularly dusty or pollen-heavy outdoor chores when your allergies are severe.

The goal is not to create a completely pollen-free home. That would be difficult. Instead, reducing the amount of pollen around you can help lower your exposure.

Try Over-the-Counter Allergy Treatments

When avoiding allergens is not enough, medication may help control symptoms.

Antihistamines are one common option. They work by blocking histamine, a chemical involved in allergic reactions. They can help with symptoms such as sneezing, itching, and a runny nose. Some antihistamines are less likely to cause drowsiness than older versions.

Nasal corticosteroid sprays are another common treatment. These medications reduce inflammation in the nose and can help with congestion, sneezing, and a runny or itchy nose. Mayo Clinic notes that nasal corticosteroids are often among the most effective treatments for seasonal hay fever.

Other options include antihistamine nasal sprays, allergy eye drops, and saline nasal sprays or rinses.

Not every medication is right for every person. Some can cause side effects or interact with other medications. If you have other medical conditions, take prescription medications, are pregnant, or are unsure what to use, talk with a health care professional or pharmacist before starting a new allergy medicine.

Consider a Saline Nasal Rinse

A saline nasal rinse is another option for people dealing with congestion. Instead of using medication, saline irrigation uses a saltwater solution to rinse mucus and allergens from the nasal passages.

It can be especially useful when your nose feels stuffed up after spending time outdoors.

If you use a neti pot, squeeze bottle, or another nasal irrigation device, water safety is extremely important. Mayo Clinic recommends using distilled or sterile water, or water that has been boiled and cooled. Tap water should not be used for nasal irrigation because it may contain organisms that can cause serious infections.

Always clean the device according to the manufacturer's directions.

Start Managing Allergies Before They Become Severe

Waiting until your symptoms become unbearable is not always the best strategy.

If you know that you usually have allergy problems during a particular season, talk with your health care professional about when to begin treatment. Some allergy medications work best when used consistently rather than waiting until symptoms are at their worst.

You can also keep track of your symptoms from year to year. Write down when they begin, how long they last, and what you were doing when they became worse. This information can help you recognize patterns and discuss your symptoms with a doctor.

Being prepared can make allergy season much easier to manage.

Know When to See an Allergy Specialist

Many people can control seasonal allergies with avoidance strategies and over-the-counter treatments. But if your symptoms continue despite your best efforts, it may be time to seek professional help.

An allergist can perform testing to determine which substances are triggering your symptoms. Allergy testing may involve a skin test or blood test. Once your triggers are identified, your health care professional can help create a treatment plan.

For people with significant allergies that do not respond well to other treatments, immunotherapy may be an option. Allergy shots expose the body to gradually increasing amounts of specific allergens in an effort to change the immune system's response. Some allergies can also be treated with tablets placed under the tongue.

These treatments take time, so they are not a quick solution for a single bad allergy day. However, they can be useful for people whose allergies have a major effect on their quality of life.

Don't Let Allergies Take Over Your Season

Seasonal allergies can make beautiful spring, summer, and fall days much less enjoyable, but they do not have to control your life.

Start by learning which allergens cause your symptoms and when they are most likely to appear. Watch pollen forecasts, limit outdoor exposure when levels are high, keep pollen out of your home, and shower or change clothes after spending time outside.

When those steps are not enough, medications such as antihistamines and nasal corticosteroid sprays may provide relief. Saline rinses can also help with congestion when used safely.

Most importantly, do not assume you have to live with severe symptoms. If your allergies are interfering with sleep, work, school, exercise, or everyday activities, talk with a health care professional. There are several treatment options available, and finding the right combination can make a major difference.

Managing seasonal allergies is ultimately about finding a routine that works for you. With some preparation and the right approach, you can spend less time thinking about sneezing and congestion and more time enjoying the seasons.
