What is Asthma

Asthma is a chronic condition that many people suffer from. Currently there is no known cure but there are many ways to help control asthma.

While these facts are relatively well known did you also know that there are several different types of asthma?

Airtamer is committed to helping all of our readers understand the different types of asthma and how to help control the symptoms related to each.  Two lesser-known but important types are cough-variant asthma (CVA) and nocturnal asthma. These conditions often go undiagnosed because their symptoms can be subtle or mistaken for other respiratory issues. Understanding them is essential for early diagnosis and effective management.

In this article, we will explore the causes, symptoms, triggers, and treatment options for cough-variant and nocturnal asthma, along with practical tips for better control.

What is Cough-Variant Asthma?

Cough-Variant asthma is a less common form of asthma that is difficult to diagnose. The only symptom associated with this form is, cough. It presents as a dry and non-productive cough meaning that the cough does not rid the lungs and airways of mucus. Cough-Variant asthma is most commonly found in young children and can often lead to classic asthma.

This form of asthma has no known cause, but allergens and certain medications like beta-blockers can trigger it. A methacholine challenge can determine if you have Cough-Variant asthma.

This involves a physician administering small doses of methacholine mist while the patient performs a spirometry test, which measures the amount of air you inhale and exhale. A positive diagnosis for cough-variant asthma means that your lung function has decreased by 20 percent or more.

Key Symptoms of Cough-Variant Asthma

• Chronic dry cough lasting more than 6–8 weeks
• Cough that worsens at night or early morning
• Increased coughing after exercise or exposure to cold air
• No obvious wheezing in many cases

Common Triggers

Understanding triggers is essential for controlling symptoms. Common causes include:

• Dust and pollution
• Pollen and seasonal allergens
• Cold air or sudden temperature changes
• Strong odors or smoke
• Respiratory infections

What is Nocturnal Asthma?

Nocturnal asthma is a very serious form of asthma. It occurs when asthma symptoms are present at night or during your sleep cycle. As with other forms of asthma, the causes are unknown.

Explanations for nocturnal asthma can include an increased exposure to allergens at night, the cooling of airways, lying in a reclined position, hormone secretions during circadian cycles, and GERD. Nocturnal asthma is common in children representing almost half of the child asthma sufferers.

Nocturnal asthma can cause those who suffer from it to awaken during the night due to an attack at least once a week and about 40 percent of people say their symptoms awaken them nightly.

This awakening can cause sufferers to be more tired and irritable during the day, which can lead to a loss in concentration and productivity. Nocturnal asthma can also make it more difficult to control daytime asthma symptoms.

Symptoms of Nocturnal Asthma

• Frequent coughing at night
• Chest tightness during sleep
• Wheezing or shortness of breath at midnight or early morning
• Difficulty staying asleep due to breathing discomfort

Diagnosis of Cough-Variant and Nocturnal Asthma

Proper diagnosis is essential because symptoms can mimic other respiratory disorders. Doctors may use:

1. Spirometry tests to measure lung function
2. Peak flow monitoring to track breathing patterns
3. Methacholine challenge test for airway sensitivity
4. Allergy testing to identify triggers

As with all forms of asthma, if you suffer from cough-variant or nocturnal asthma you should avoid your triggers.

Asthma Relief – Best Wearable Air Purifier

To limit your exposure to allergens at night and reduce the symptoms of nocturnal asthma place an air purifier like the AirTamer A302 next to your bed at night. As cough-variant asthma can occur at any time of the day and anywhere consider one that is convenient to take with you like the AirTamer A310.

It uses negative ion technology to charge and disperse microscopic particles away from the breathing zone, potentially lowering the amount of allergens and pollutants inhaled during sleep or daily activities. This can be particularly useful in bedrooms, travel settings, or poorly ventilated indoor spaces where allergens tend to accumulate and symptoms like dry cough, chest tightness, or night-time coughing episodes can become more frequent.

Conclusion

Both cough-variant asthma and nocturnal asthma are often overlooked forms of asthma that can significantly affect daily life and sleep quality. While cough-variant asthma presents mainly as a persistent cough, nocturnal asthma disrupts rest with worsening symptoms at night.

With proper diagnosis, medication, and lifestyle changes, both conditions can be effectively managed. If you notice persistent coughing or nighttime breathing difficulties, consult a healthcare professional for timely treatment.
