It is fairly common knowledge that strength training provides the body's muscles with a workout, but fewer know how to provide the lungs with a good workout, nor the positive respiratory changes that can occur as a result of exercise. For example, did you know that regular exercise can improve lung function and reduce your risk of chronic respiratory disease? The following article aims to answer some of the most commonly asked respiratory-related questions.
The term ‘respiratory health’ refers to the health of the organs and muscle tissue that make up our respiratory system, the system responsible for helping us breathe. Therefore, a prime example of someone with ‘good respiratory health’ would be an individual with healthy respiratory organs and muscle tissue, which would be demonstrated by their unrestricted breathing. Unfortunately, our respiratory health can be temporarily and permanently impaired by certain health conditions. Conditions like the common cold and coughs can temporarily impair our ability to breathe, although for most, these types of conditions are more inconvenient than they are harmful. However, chronic respiratory conditions can pose a greater threat to our health. According to the latest statistics, chronic conditions such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer are present in roughly 540-545 million individuals worldwide.1 Alarmingly, research has identified chronic respiratory diseases as one of the leading causes of death, therefore highlighting how important it is for us to look after our respiratory health.2
Because there is a wide range of respiratory health issues, the symptoms an individual may experience can differ greatly depending on their condition. Below are some of the symptoms most common in those suffering from respiratory health issues.
According to an article published in the journal Breathe, regular exercise (particularly aerobic exercises such as jogging, cycling, and swimming) can provide a wide range of respiratory benefits.3 Below are some of the main respiratory benefits that those who exercise will likely experience.
Like weight training helps improve the strength of our muscles, aerobic-based exercises help us build a stronger and more efficient respiratory system. When performing aerobic exercises such as jogging, swimming, and cycling, the body's muscles require a higher amount of oxygen in order to create energy. Because of this, the lungs and the rest of our respiratory system have to work harder in order to ensure the muscles' oxygen demand is met. Over time, this ‘extra work’ forces the respiratory system to begin to adapt, meaning it becomes stronger and more efficient at dealing with oxygen. Below are some of the ways research has observed regular aerobic exercise improves our respiratory system.
As well as increasing the strength and efficiency of our respiratory system, regular exercise also helps maintain its health. Numerous studies have found a clear link between regular exercise and a reduced risk of chronic respiratory disease. For example, a research paper published in the Journal of Physical Activity and Health found that those who regularly exercise over the course of their lifetime were ‘significantly’ less likely to develop COPD than those who do not.4
Exercise has also been shown to provide benefits to those who have already been diagnosed with some form of respiratory disease. Research has shown that regular exercise can reduce the frequency and severity of a patient’s symptoms, whilst also improving their quality of life.5 Furthermore, other studies have found that regular exercise can also greatly improve the life expectancy of those with chronic conditions like COPD, therefore further highlighting how beneficial exercise can be.6
The psychological effect of chronic respiratory conditions is often overlooked. A 2017 study found that those diagnosed with chronic respiratory disease were more likely to develop anxiety and depression than those who did not have the condition.7 Fortunately, this is another area in which physical activity can help. An investigation found that regular exercise helped reduce the symptoms of depression and anxiety in those diagnosed with chronic respiratory disease, helping reduce their risk of also developing chronic psychological conditions like depression.5
Before beginning any sort of exercise programme, those diagnosed with any form of respiratory disease should contact their healthcare provider in order to ensure that it is safe to do so. Whilst it is mostly safe for those with respiratory health issues to exercise, there are certain risks. To ensure you remain safe during your workouts, stop exercising immediately and contact your healthcare provider if you experience any of the following symptoms:
Our respiratory system is vitally important to us, and for that reason alone should be taken care of. Based on the many studies conducted on the relationship between our respiratory health and exercise, it is clear that regularly performing aerobic exercises such as walking, jogging, cycling, and swimming can greatly benefit respiratory health, even in those who have already been diagnosed with some form of respiratory disease.
