For many living with asthma, the search for complementary strategies to manage symptoms is a constant journey. Breathing exercises are often discussed, but what does the science say? This is a look at the evidence for their benefits and crucial limits.
An Introduction to Breathing Techniques
Several structured breathing techniques have gained popularity for asthma management. The most studied include the Buteyko method, which involves controlling breath to reduce over-breathing (hyperventilation); the Papworth method, which combines diaphragmatic breathing with relaxation; and general diaphragmatic or 'belly' breathing. The common goal of these practices is to retrain breathing patterns, aiming for slower, calmer, and more efficient respiration, primarily through the nose and using the diaphragm muscle rather than the chest and shoulders. Many people with asthma adopt dysfunctional breathing patterns, which can worsen feelings of breathlessness, and these exercises are designed to help correct that.
The Evidence for Symptom Improvement
The strongest evidence for breathing exercises lies in their ability to improve quality of life and reduce symptoms. Multiple studies, including a major Cochrane review, have shown that people with mild to moderate asthma who practice these techniques report feeling better. A trial on the Papworth method found it reduced respiratory symptoms by a third, an effect that was maintained even a year later. Similarly, research on the Buteyko method has shown it can significantly reduce asthma symptoms and improve quality of life. These benefits also extend to psychological well-being, with studies noting reductions in anxiety and depression among participants.
Can You Use Your Inhaler Less?
One of the most appealing claims is that these practices can reduce the need for medication. The evidence here is promising but requires careful interpretation. Several studies have found that consistent practice of techniques like the Buteyko method can lead to a significant decrease in the use of reliever (rescue) inhalers, sometimes by as much as 50% or more. Some research has even shown that doses of preventer (controller) medication could be halved in some patients with mild asthma. However, this reduction in medication use is a result of better symptom control, not a change in the underlying disease. The exercises help manage the day-to-day feelings of breathlessness, leading to less reliance on immediate relief.
Understanding the Crucial Limitations
This is where understanding the limits becomes critical. While breathing exercises can make a person feel better and reduce their symptoms, there is no strong evidence that they improve core lung function. Objective measures like FEV1 (the amount of air you can force out in one second) generally do not show significant change. This means the exercises are not reversing the fundamental airway inflammation and constriction that defines asthma. Therefore, they are not a cure. Pulmonologists and asthma organisations are clear on one point: breathing exercises are a complementary therapy, not a replacement for prescribed medication. Stopping the use of preventer inhalers without medical guidance can be dangerous, as the underlying inflammation would be left untreated.
Integrating Practice with Medical Care
The safest and most effective way to incorporate breathing practices into your asthma care is to view them as a supportive tool within your doctor-approved management plan. Think of them as strengthening your respiratory muscles and improving your ability to control your breathing, especially during moments of stress or mild breathlessness. Before starting any new regimen, it is essential to discuss it with your doctor or a respiratory physiotherapist. They can help ensure the technique is right for you and that it complements, rather than conflicts with, your existing treatment. A trained professional can also provide proper instruction, which is key to achieving the best results and avoiding improper technique.
