Good news for those singing birds: your time humming in the boys choir has been good for your breathing. According to this observational study by researchers from Canterbury Christ Church University, singing in a choir may help those with congestive obstructive pulmonary disease (COPD), a condition that makes breathing difficult, breathe easier. See How To Seduce Her With A Song and How To Become The King Of Karoake. Those with COPD have a tendency to take short gasps of breath, which can escalate COPD, while singing gets people to breathe more deeply. Singing can gradually improve the musculature around the lungs, throat, and upper chest to improve lung function. In this study, over 100 participants with COPD attended weekly 90 minute sessions of socialising and 60 minutes of singing. Researchers collected info on their lung function and their qualitative evaluation of their feelings at the start, middle and end of the 10 month study. The results? At the end of the study, both lung function and health-related quality of life improved. Researchers found an increase of 30ml loss in Forced Expiratory Volume, the amount of air that can be forcefully exhaled in a second, though they hoped to find a 40ml loss in Forced Expiratory Volume. Participants reported that partaking in singing groups was enjoyable and that the quality of their life and well-being improved. Dr Ian Morrison, the lead author of the study, says that chronic disease is isolating, so socialising and getting out can help improve well-being. A controlled randomised trial is needed to further explore the effect of singing on lung function and well-being among those with COPD.
