Living Well with Asthma & Allergies
Asthma and allergies are two of the most common long-term health conditions in the country — and they often go hand in hand. Nearly 28 million people in the U.S. live with asthma, and allergies affect millions more. Both are manageable, and understanding them is the first step toward living well.
What Is Asthma?
Asthma causes the airways to become swollen and inflamed, making it harder to breathe. There is no cure, but it can be effectively controlled so it doesn't interfere with daily life.
Common symptoms include:
- Coughing (especially at night or early morning)
- Shortness of breath
- Wheezing
- Chest tightness or pressure
Symptoms can range from mild to severe. A severe episode — sometimes called an asthma attack — is a medical emergency. Knowing the warning signs and having a plan in place matters.
What Are Allergies?
Allergies happen when the body's immune system identifies a harmless substance as a threat and overreacts to it. Those substances are called allergens. When exposed to an allergen, the immune system produces antibodies (immunoglobulin E, or IgE) that trigger a reaction.
Common allergens include:
- Pollen
- Pet dander (from urine, saliva, or skin)
- Dust mites and cockroaches
- Mold
- Insect stings or bites (bees, wasps, mosquitoes, ticks)
- Certain foods
- Medications (drug allergies)
- Latex
Common allergy symptoms include:
- Watery or itchy eyes
- Runny nose and sneezing
- Skin rash or hives
- Itchy throat
More serious symptoms — such as difficulty breathing or swelling in the mouth or throat — may signal anaphylaxis, a life-threatening allergic reaction that requires immediate medical attention.
The Asthma and Allergy Connection
Many of the same things that trigger allergies can also trigger asthma. Common shared triggers include pollen, animal dander, dust mites, mold, air pollution, smoke, strong scents or fragrances, and extreme weather changes. Stress and physical exercise can also bring on asthma symptoms.
Not everyone has the same triggers. Identifying yours is one of the most important steps in managing both conditions.
How to Manage Asthma
Living well with asthma comes down to three things:
- Know your triggers — and reduce your exposure to them as much as possible
- Follow your treatment plan — take prescribed medications on schedule, not just when symptoms flare
- Be prepared — keep your quick-acting (rescue) inhaler with you and use it at the first sign of symptoms
Working closely with a doctor to create a written asthma action plan makes a real difference. Many people — including professional athletes — live healthy, active lives with well-managed asthma.
How to Manage Allergies
Allergy treatment is based on your medical history and the severity of your symptoms. It typically involves one or more of the following:
- Avoidance — identifying and steering clear of your allergens whenever possible
- Medication — over-the-counter or prescription options to reduce symptoms
- Immunotherapy — a treatment that gradually trains the immune system not to overreact to specific allergens
Avoidance isn't always fully possible. For example, if you're allergic to bee stings, you can reduce your risk but can't avoid the outdoors entirely. In those cases, having the right medication on hand — such as an epinephrine auto-injector — and knowing how to use it is essential.
The goal is to stay prepared so allergies don't control your life. With proper care and guidance from an allergist, most people manage their symptoms well and go about their normal routines at home, work, and school.
When to See a Doctor
If you or someone you love is experiencing symptoms that are frequent, hard to control, or worsening over time, don't wait. Early diagnosis and a consistent care plan make a significant difference in quality of life.
