Can Stress Make Allergies Worse?

Yes, stress can make allergy symptoms feel worse. While stress doesn’t actually cause allergies, research suggests it can amplify your body’s immune response and even change how intensely you experience symptoms.

During Philadelphia’s grass pollen season – especially when bluegrass and ryegrass pollen levels are high – this connection between stress and allergies can leave many people feeling miserable.

How Are Stress and Allergies Connected?

Stress is your body’s natural response to a challenge or perceived threat. Whether you’re facing a work deadline, financial worries, or a family emergency, your brain signals the release of hormones like cortisol and adrenaline.

These hormones affect nearly every system in your body – including your immune system.

An allergy is also an immune response. Instead of ignoring a harmless substance like pollen, your immune system mistakenly identifies it as a threat and releases chemicals, including histamine, to defend your body.

Histamine is responsible for many familiar allergy symptoms, including:

• Sneezing
• Itchy, watery eyes
• Runny nose
• Nasal congestion
• Swelling

Research suggests that stress may increase inflammatory activity and influence histamine release, potentially making allergy symptoms feel more intense. Stress can also heighten your awareness of discomfort, meaning symptoms that were once manageable may suddenly seem overwhelming.

In other words, stress and allergies can create a frustrating cycle: allergies increase stress, and stress may make allergies feel worse.

Can Stress Trigger Allergies?

This is one of the most common questions patients ask.

The answer is not exactly.

Stress doesn’t create an allergy if you aren’t already allergic to something. However, if you have seasonal allergies, stress may increase the severity of your symptoms or make flare-ups more noticeable.

Researchers continue to study the relationship between stress and allergic disease, but there is growing evidence that chronic stress can influence how the immune system responds to allergens.

What Does the Research Say?

Several studies have found an association between psychological stress and increased allergy symptoms.

One study found that people experiencing high levels of emotional stress reported more frequent allergy flare-ups than those with lower stress levels. Another study suggested that learning stress-management techniques may reduce the likelihood of allergy symptoms following stressful life events.

While stress reduction is not considered a standalone allergy treatment, improving emotional well-being may complement traditional allergy care.

Can Reducing Stress Help Your Allergies?

Managing stress won’t eliminate pollen from the air, but it may help reduce the impact allergies have on your daily life.

Simple habits that support both your overall health and your immune system include:

• Getting 7-9 hours of quality sleep
• Exercising regularly
• Practicing deep breathing, meditation, or mindfulness
• Taking breaks from work and making time for hobbies
• Setting healthy boundaries and avoiding unnecessary stress when possible

Many patients also find that staying well-hydrated and maintaining healthy routines helps them better cope with allergy season.

Don’t Forget the Basics

Stress management works best alongside proven allergy treatments.

Depending on your symptoms, your ENT or allergy specialist may recommend:

• Antihistamines
• Nasal corticosteroid sprays
• Saline nasal irrigation
• Eye drops
• Decongestants (when appropriate)
• Allergy immunotherapy (allergy shots or sublingual tablets) for long-term relief

It’s also helpful to reduce pollen exposure by keeping windows closed on high-pollen days, showering after spending time outdoors, and changing clothes after yard work or exercise.

When Should You See an ENT or Allergy Specialist?

If allergies are interfering with your sleep, work, exercise, or daily activities – or over-the-counter medications no longer provide enough relief – it may be time for a professional evaluation.

An ENT specialist can determine exactly what’s triggering your symptoms, identify other conditions that may mimic allergies, and develop a personalized treatment plan that helps you breathe easier throughout allergy season.

The Bottom Line

Stress won’t give you allergies, but it can make living with them more difficult.

By combining healthy stress-management habits with effective allergy treatment, many people are able to reduce symptoms and enjoy life – even during Philadelphia’s  busiest pollen season.
