Asthma and headaches: Is there a connection?

Understanding the Link Between Asthma and Headaches

Asthma is widely recognized as a chronic respiratory condition that makes breathing difficult. It affects millions of people worldwide, triggering symptoms like wheezing, chest tightness, and shortness of breath. But can asthma also lead to headaches—or be linked to migraine and tension headaches?

Surprisingly, research increasingly suggests that people living with asthma may be more likely to experience certain types of headaches, including migraines and tension headaches. This connection is not fully understood yet, but studies have highlighted several biological, neurological, and environmental factors that may explain the overlap.

In this article, we’ll explore the relationship between asthma and headaches, discuss how asthma medications might play a role, describe what asthma-related headaches feel like, and cover potential treatment strategies.

Can Asthma Cause Headaches? Here’s What the Evidence Shows

While headaches aren’t a direct symptom of asthma, there’s compelling evidence that asthma may make individuals more prone to developing migraines and tension-type headaches.

A notable 2015 study found that people with asthma—especially those with more severe symptoms—were more likely to go from having episodic migraines (occasional) to chronic migraines (frequent). This progression suggests a link beyond coincidence.

So what might explain this relationship?

Potential Biological Links Between Asthma and Headaches:

• Mast Cell Degranulation: Mast cells release histamine and other chemicals during allergic reactions and inflammation. These substances can influence both respiratory and neurological responses.
• Autonomic Nervous System Dysfunction: The autonomic nervous system controls involuntary functions like breathing and heartbeat. Imbalances in this system have been associated with both asthma and migraine.
• Shared Genetic or Environmental Triggers: A 2018 study found that both migraine sufferers and asthmatics are more likely to seek hospital care when air quality is poor, suggesting environmental triggers may play a role in both conditions.

Further supporting this connection, a 2017 study found that asthma patients have a higher likelihood of experiencing both tension and migraine headaches. And a 2019 study indicated the link might be bidirectional—meaning people with migraines are also more likely to develop asthma, and vice versa.

By 2021, yet another study reinforced these earlier findings, pointing to a mutual risk between the two disorders.

Even though researchers haven’t pinpointed a single cause behind this connection, the evidence clearly shows that asthma and headaches often go hand-in-hand.

Can Asthma Medications Trigger Headaches?

Sometimes, it’s not the asthma itself—but the medications used to treat it—that could be behind a headache. Almost all asthma medications come with potential side effects, and headaches are a relatively common one.

Here are some common asthma medications that may cause headaches:

• Leukotriene Receptor Antagonists (e.g., montelukast)
• Inhaled Beta-2 Agonists (short- and long-acting)
• Muscarinic Antagonists (short- and long-acting)
• Inhaled Corticosteroids

If you notice that headaches started after beginning a new asthma medication, don’t ignore it. Speak with your doctor—they may be able to switch you to a different drug, adjust your dose, or suggest ways to manage side effects effectively.

What Does an Asthma-Related Headache Feel Like?

The type and intensity of headaches linked with asthma—or its medications—can vary. Most often, they fall into two major categories:

1. Migraine Headaches

• Pain Type: Throbbing or pulsating
• Location: Usually on one side of the head
• Associated Symptoms:
  • Nausea or vomiting
  • Sensitivity to light and sound
  • Blurred vision or aura in some cases

These headaches can be debilitating and may last for hours or even days if not treated promptly.

2. Tension-Type Headaches

• Pain Type: Dull, aching, and steady
• Location: Affects both sides of the head
• Other Features:
  • Pressure or tightness across the forehead or scalp
  • Tenderness in neck and shoulder muscles
  • May be triggered by stress or muscle tension

Understanding the nature of your headaches can help your healthcare provider tailor the right treatment strategy for both your asthma and your headache symptoms.

Other Common Asthma Symptoms to Watch For

In addition to a potential link with headaches, asthma has well-defined primary symptoms that include:

• Shortness of breath
• Chest tightness or discomfort
• Persistent coughing, especially at night or early morning
• Wheezing or a whistling sound when breathing

If you’re dealing with these symptoms regularly, it’s a strong sign that your asthma needs better control. And if you’re also experiencing headaches, it’s time to discuss both issues with your doctor.

Treatment Options for Asthma and Associated Headaches

While there’s no cure for asthma, it can be effectively managed with the right medication, lifestyle changes, and trigger avoidance. The same goes for headaches—particularly migraines—which can also be managed with preventive and abortive medications.

Managing Tension Headaches

• Over-the-counter pain relief: Such as acetaminophen or ibuprofen
• Relaxation techniques: Yoga, meditation, deep breathing
• Proper hydration and rest

Treating Migraine Headaches

Doctors may prescribe a variety of medications based on the frequency and severity of migraines:

Abortive (Acute) Treatments:

• Triptans (e.g., sumatriptan)
• NSAIDs (e.g., naproxen)
• Combination pain relievers
• Anti-nausea medications
• Ergotamine derivatives

Preventive Medications:

• Anti-CGRP drugs (e.g., erenumab)
• Beta-blockers (e.g., propranolol)
• Anticonvulsants (e.g., topiramate)
• Antidepressants
• Calcium channel blockers

It’s essential to work with your doctor to develop a treatment plan that considers both your asthma and headaches to avoid potential drug interactions and ensure the best outcomes.

When Should You Talk to a Doctor?

If you’re experiencing asthma symptoms for the first time or noticing that your current asthma treatment isn’t keeping symptoms under control, don’t delay—see a healthcare provider right away. Early diagnosis and effective treatment are crucial in preventing long-term damage and improving your quality of life.

Also, if you begin to experience new or worsening headaches, or if your headaches seem to coincide with starting a new asthma medication, that’s another clear reason to check in with your doctor. Sometimes, simple adjustments in your treatment plan can make a significant difference.

Here are some red flags that warrant medical attention:

• Headaches that persist for several days
• Migraines that occur more frequently than usual
• Headaches that disrupt daily activities or sleep
• Headaches combined with vision problems, dizziness, or confusion
• Headaches that begin after a change in medication

Don’t try to self-diagnose or push through discomfort. Whether the headache is a side effect or part of a more complex relationship between asthma and neurological symptoms, a doctor can guide you toward the most effective path forward.

Real-Life Tips for Managing Asthma and Headaches Together

Living with both asthma and headaches can feel overwhelming—but there are several proactive strategies that can help you manage both conditions and improve your quality of life.

1. Identify and Avoid Shared Triggers

Both asthma and headaches can be triggered by environmental factors, so paying attention to what sparks symptoms is key.

Common triggers include:

• Air pollution or poor indoor air quality
• Strong odors or perfumes
• Cigarette smoke
• Changes in weather or barometric pressure
• Stress and anxiety
• Certain foods or drinks (like red wine, aged cheese, or processed meats)

Try keeping a symptom diary to track when your asthma or headaches flare up. Over time, patterns will emerge that can help you and your doctor tailor your prevention strategies.

2. Practice Stress Reduction Techniques

Stress is a known trigger for both asthma and tension headaches. Incorporating mind-body techniques into your daily routine may reduce the frequency and intensity of both conditions.

Effective options include:

• Meditation or mindfulness
• Breathing exercises
• Light physical activity like walking or yoga
• Progressive muscle relaxation

3. Prioritize Sleep and Hydration

Lack of sleep and dehydration are two often-overlooked factors that can make both asthma and headaches worse. Try to maintain a regular sleep schedule and aim for 7–9 hours of restful sleep per night. Drink plenty of water throughout the day to stay hydrated—especially if you live in a dry climate or are physically active.

4. Use Medications as Directed

Whether you’re taking daily controller medication for asthma or prescribed abortive meds for migraines, consistency matters. Skipping doses, taking too much, or using medications incorrectly can lead to rebound symptoms, side effects, or reduced effectiveness.

Always follow your doctor’s instructions and consult them before making any changes.
