Hay fever and asthma—two terms often thrown around in conversations about allergies, but did you know these conditions are more closely connected than you might think? Hay fever, also known as allergic rhinitis, and asthma are both common conditions that can significantly impact your quality of life. They share a sneaky culprit: an overactive immune system reacting to everyday allergens like pollen, dust mites, and mould.

While each condition has its own set of tell-tale symptoms, they often coexist and even exacerbate one another, making life even more challenging for those affected. In this blog, we’ll dive into the intriguing relationship between hay fever and asthma, explore their unique symptoms, and explain how they can influence each other in unexpected ways.

What is hay fever?

Hay fever, or allergic rhinitis, is a condition that many of us know all too well—characterised by the dreaded combination of sneezing, a runny or blocked nose, and those relentless itchy eyes. It’s essentially your body’s way of overreacting to harmless substances like pollen, dust mites, or pet dander, treating them as if they were a serious threat. This overactive immune response results in inflammation in the nose, eyes, and throat, leading to the symptoms that can make life miserable, especially during the peak of spring or a dusty autumn day.

Common symptoms:

• Sneezing
• Runny or blocked nose
• Itchy or watery eyes
• Itchy throat or ears

Hay fever can present itself in two main forms: seasonal and perennial. Seasonal hay fever tends to strike during specific times of the year when pollen counts are high, such as in spring or summer. Many Australians find their symptoms peaking from September to December, making it tough to enjoy the great outdoors. 

Perennial hay fever, however, is a year-round struggle, often caused by indoor allergens such as dust mites and pet dander, which can be particularly troublesome in homes that aren’t well-ventilated or cleaned.

Next, let’s explore how asthma weaves into this picture of allergic reactions.

What is asthma?

Asthma is a chronic respiratory condition that affects the airways in your lungs, making it difficult to breathe. Imagine your airways as tubes carrying air in and out of your lungs. In someone with asthma, these tubes can become inflamed and narrowed, causing a range of troublesome symptoms that can vary from mildly annoying to downright frightening.

Common symptoms:

• Wheezing (high-pitched whistling sound when you breathe)
• Shortness of breath
• Persistent coughing
• Chest tightness

Asthma symptoms can be unpredictable and are often triggered by a variety of factors. It comes in different forms. There’s allergy asthma, where symptoms are triggered by allergens like pollen, dust, or pet dander, similar to hay fever. Then there’s non-allergy asthma, which isn’t linked to allergens but can be triggered by factors such as stress, cold air, or exercise.

Now that we’ve covered the basics of hay fever and asthma, let’s explore how these two conditions are more connected than you might think.

How hay fever and asthma are connected

Hay fever and asthma often go hand in hand, a connection rooted in what’s known as the “allergic march.” This concept explains how allergic conditions can progress and coexist, starting from eczema in early childhood to hay fever and eventually asthma. Both hay fever and asthma involve an overactive immune response to allergens such as pollen, dust mites, and mould, which is why it’s common for people to experience both conditions simultaneously.

Impact of hay fever on asthma

When hay fever inflames the upper respiratory tract—the nose and throat—it can easily spread down to the lower respiratory tract, where it worsens asthma symptoms. This connection means that if your hay fever is left unmanaged, it can trigger or exacerbate asthma symptoms, such as wheezing and shortness of breath. Essentially, the inflammation caused by hay fever can act as a domino effect, making breathing even more difficult for those who have asthma.

During high-pollen seasons, the likelihood of asthma flare-ups increases significantly for those suffering from both conditions. This is because the immune system is already on high alert due to hay fever, making it more sensitive and reactive to other triggers that might not usually cause a problem. As a result, people with both hay fever and asthma may find themselves reaching for their inhalers more often during spring and summer.

The role of allergens

Allergens such as pollen and dust mites are double trouble, as they can trigger both hay fever and asthma at the same time. When these tiny particles are inhaled, they can cause inflammation in the nose, eyes, and lungs, leading to a full spectrum of symptoms ranging from sneezing and itchy eyes to coughing and wheezing.

Differences in symptoms between hay fever and asthma

Despite their close connection, hay fever and asthma manifest in distinct ways, primarily affecting different parts of the body.

Hay fever symptoms

Hay fever is most commonly felt in the upper respiratory tract, focusing its annoying effects on the nose, eyes, and throat. If you’ve ever found yourself in a sneezing fit after stepping outside on a high-pollen day, you’re familiar with its tell-tale signs.

Hay fever symptoms, while uncomfortable and often disruptive, don’t usually involve breathing difficulties or chest-related issues.

Asthma symptoms

Asthma, on the other hand, is a condition that targets the lower respiratory system—your lungs and airways—making it hard to breathe.The symptoms are more serious and can be life-threatening if not managed properly, unlike the upper respiratory symptoms of hay fever.

Overlap of symptoms

While the symptoms of hay fever and asthma typically affect different areas, there can be some overlap for those who have both conditions. For example, a persistent cough could be due to post-nasal drip from hay fever irritating the throat and triggering asthma. This overlap can make it challenging to determine which condition is at play, but understanding their distinct symptoms helps in managing them effectively.

 

Managing hay fever to help control asthma

Effectively managing hay fever is not only crucial for reducing its own symptoms but can also play a significant role in keeping asthma under control. By minimising hay fever flare-ups, you can help prevent the chain reaction that often leads to asthma attacks. Here are some strategies and treatments that can help manage hay fever, ultimately making it easier to keep asthma symptoms at bay.

Medications for hay fever

• Antihistamines: These are often the first line of defence against hay fever symptoms. They work by blocking the action of histamine, the chemical responsible for the sneezing, itching, and runny nose associated with allergies. By keeping these symptoms in check, antihistamines can also help prevent the nasal congestion and post-nasal drip that may aggravate asthma. Just be mindful of choosing non-drowsy options if you plan on driving or working.

• Nasal corticosteroids: These are highly effective in reducing inflammation in the nasal passages, which is crucial for preventing the upper respiratory inflammation that can spread and trigger asthma symptoms. Using nasal corticosteroids regularly during hay fever season can provide significant relief and protection against asthma flare-ups.

• Decongestants: While these can provide quick, short-term relief from a blocked nose, they should be used with caution. Overuse or prolonged use can sometimes lead to a rebound effect, making nasal congestion worse. Additionally, decongestants may elevate heart rate and blood pressure, potentially aggravating asthma in some individuals. It’s best to use them sparingly and under the guidance of a healthcare professional.

Asthma medications

• Preventer inhalers: These are a must for anyone with asthma, especially during hay fever season. Preventer inhalers contain corticosteroids that reduce inflammation in the airways, helping to keep them clear and less reactive. Using them regularly, even when you’re feeling fine, is key to preventing asthma attacks. For better results, using a spacer with your inhaler can help deliver the medication more effectively to your lungs. There are various types of spacers available, from compact, travel-friendly ones to larger versions with masks, so you can choose the one that best suits your needs and lifestyle.

• Reliever inhalers: Always have your reliever inhaler on hand. It provides quick relief from symptoms like wheezing and shortness of breath if they do occur. Using a spacer with your reliever inhaler can also be beneficial, especially for children or anyone who finds it difficult to coordinate their breathing with the use of the inhaler.

In addition to medications, controlling your environment can greatly reduce exposure to the allergens that trigger both hay fever and asthma:

• During high-pollen days, keep windows and doors shut to prevent pollen from entering your home.

• Consider investing in a high-efficiency particulate air (HEPA) filter for your home. It can help remove airborne allergens like pollen, dust mites, and pet dander.

• Regularly clean your living space, including bedding and soft furnishings, to reduce dust mites and pet dander. 

• Washing clothes after being outdoors can also help minimise pollen exposure.

• Mould can be a significant trigger for both hay fever and asthma. To prevent mould growth, especially in areas prone to humidity like bathrooms and kitchens, use mould prevention solutions. For a natural option, consider using SAN-AIR, an Australian brand known for its comprehensive range of mould removal and prevention products. These solutions can help keep your home mould-free and reduce the risk of asthma flare-ups.

• When you’re out and about, especially during high-pollen days or in areas with poor air quality, wearing a mask can help protect you from inhaling allergens. P2 or N95 masks are recommended as they offer 95% filtration efficiency, providing better protection against airborne particles. For an even higher level of protection, consider the AMD P2 mask, which boasts a Particle Filtration Efficiency (PFE) of ≥99.66%, outperforming standard P2 or surgical masks.

Combining these strategies can help you manage hay fever more effectively, reducing its impact on asthma and allowing you to enjoy life with fewer interruptions from these bothersome conditions.

Knowing when to seek medical support

While managing hay fever and asthma can often be done at home with the right combination of medications and lifestyle changes, there are times when professional guidance is essential. Knowing when to seek medical advice can make a significant difference in your quality of life and help prevent more serious complications.

Consult your doctor

If you notice that your symptoms are persistent, worsening, or not responding to your usual treatment plan, it’s important to consult your healthcare provider. This is particularly crucial if you experience frequent asthma attacks, severe shortness of breath, or if your hay fever symptoms are making daily activities difficult. Your doctor can assess your current condition and adjust your treatment plan to better suit your needs, ensuring you have the best strategies in place for both prevention and relief.

Get an allergy test

If you’re struggling to pinpoint the specific triggers behind your symptoms, you can consider doing an allergy test. Identifying exactly what’s causing your hay fever and asthma symptoms—whether it’s pollen, dust mites, pet dander, or something else—can help you tailor your management plan more effectively. With this information, you and your healthcare provider can develop a strategy that targets these specific allergens, potentially reducing the frequency and severity of your symptoms.

Create a combined action plan

For those managing both hay fever and asthma, having a personalised action plan is essential. Work with your doctor to create a combined plan that addresses both conditions. This should include a list of your medications and when to take them, strategies for avoiding triggers, and steps to take in case of an emergency. An action plan not only provides clarity on how to manage day-to-day symptoms but also ensures that you’re prepared if things take a turn for the worse. This proactive approach can help you maintain better control over both conditions and reduce the risk of severe flare-ups.
