A sudden onset of sneezing, itchy eyes, or even difficulty breathing can be alarming. If you’re a Miami resident, you know that allergies are common in this subtropical climate. But how long do allergic reactions typically last, and when should you seek medical attention? Let’s dive in and uncover the answers.

What is an Allergic Reaction? Your Immune System on Overdrive

It’s not the allergen itself that’s harmful: It’s your body’s exaggerated response. When exposed to something you’re allergic to (pollen, pet dander, certain foods), your immune system releases chemicals like histamine, triggering those familiar, unpleasant symptoms.

Symptoms of an Allergic Reaction: Beyond the Sneeze

Allergic reactions can manifest in a variety of ways, from mild to severe:

• Respiratory: Sneezing, runny nose, itchy or watery eyes, cough, wheezing, difficulty breathing.
• Skin: Hives (raised, itchy welts), eczema flare-ups, redness, itching.
• Digestive: Nausea, vomiting, diarrhea, abdominal cramps, swelling of the lips or tongue.
• Other: Fatigue, headache, dizziness, anaphylaxis (a life-threatening reaction)

How Long Do Allergic Reactions Last?

The duration varies significantly depending on the type of allergy, your level of exposure, and individual factors:

• Mild Reactions: May last a few hours or a few days, often resolving on their own or with over-the-counter antihistamines.
• Moderate Reactions: Can last for several days or even weeks, depending on continued exposure to the allergen.
• Severe Reactions: Anaphylaxis is a medical emergency requiring immediate treatment. Its effects can be prolonged, sometimes requiring hospitalization.

Are Allergies Contagious?

No, allergies themselves are not contagious. You cannot “catch” someone else’s allergy to pollen or peanuts. However, some triggers, like the common cold virus, are contagious, and catching a cold can exacerbate allergy symptoms.

Biggest Difference Between Cold and Allergies

Many symptoms overlap (runny nose, sneezing, cough), but here’s the key distinction:

• Colds: Caused by viruses, they typically last 7-10 days and often involve a fever.
• Allergies: Triggered by allergens, they can last much longer (throughout pollen season, for example) and rarely involve a fever.
