Spring Allergies or Something Else? How to Tell the Difference…

As spring arrives in Oregon, many people notice familiar symptoms like sneezing, congestion, and watery eyes. With trees blooming and pollen levels rising, seasonal allergies are a common cause. But these same symptoms can also overlap with colds, sinus infections, or other illnesses.

At South Tabor Family Physicians, one of the most common questions we hear this time of year is: “Is this just allergies or am I getting sick?” Understanding the differences can help you manage symptoms more effectively and know when it’s time to check in with a health care provider.

Why Spring Allergies Are So Common in the Pacific Northwest

The Portland area and surrounding regions experience high pollen levels in the spring, especially from trees such as alder, birch, and cedar. Even on rainy days, pollen can remain in the air or build up over time.

Seasonal allergies, also called allergic rhinitis, occur when the immune system reacts to pollen or other environmental triggers. While not dangerous for most people, allergies can be uncomfortable and disruptive to daily life.

Common Symptoms of Seasonal Allergies

Allergy symptoms often develop gradually and can last for weeks or even months during peak seasons. Typical symptoms include sneezing, a runny or stuffy nose, itchy or watery eyes, postnasal drip, and an itchy throat or ears. Many people also experience fatigue, especially if symptoms interfere with sleep. Unlike infections, allergies do not cause fever and are not contagious.

How Colds and Illnesses Differ

Colds and other respiratory illnesses can look similar at first, but there are key differences.

Colds usually develop over a few days and tend to last about 7 to 10 days. Symptoms may include congestion, cough, sore throat, mild body aches, and sometimes a low-grade fever.

Illnesses are caused by viruses, meaning they can spread from person to person. Symptoms often improve gradually and then resolve.

Signs It May Be Something More Than Allergies

While allergies and colds are common, certain symptoms may suggest a different condition that should be evaluated. These include a persistent high fever, shortness of breath, severe sinus pain, symptoms lasting longer than 10–14 days without improvement, or worsening symptoms after initially feeling better.

If symptoms feel different than your usual seasonal allergies or are interfering with daily life, it is a good idea to check in with a health care provider.

Quick Comparison: Allergies vs. Illness

While symptoms can overlap, a few general patterns can help:

> Allergies tend to cause itching (eyes, nose, throat), last longer, and do not include fever.
> Colds or infections are more likely to include body aches, sore throat, and sometimes fever, and typically resolve within a shorter timeframe. If you are unsure, a provider can help clarify the cause.

Simple Ways to Manage Seasonal Allergy Symptoms

While you cannot completely avoid pollen, small steps can help reduce exposure and improve symptoms. Keeping windows closed during high pollen days, using air filters indoors, and showering after spending time outside can help limit allergens. Washing bedding regularly and avoiding outdoor activities during peak pollen times may also be helpful.

Over-the-counter antihistamines, nasal sprays, or other medications may provide relief. It is always a good idea to talk with your provider about what options are safest and most effective for you.

Supporting Your Immune System During Spring

Good overall health can help your body respond more effectively to seasonal changes.

Getting enough sleep, staying hydrated, eating balanced meals, and incorporating regular movement can all support immune function. Managing stress also plays an important role in how your body handles both allergies and illness.

When to Schedule a Visit

You may want to schedule an appointment if symptoms are not improving with basic measures, are affecting sleep or daily activities, or if you are unsure whether you are dealing with allergies or an illness. For some patients, allergy symptoms can also trigger asthma or worsen other conditions, making evaluation even more important.
