Choir singing as an activity to manage anxiety and temporomandibular disorders: Reports from a Brazilian sample

The aim of this study was to evaluate anxiety, stress and symptoms of temporomandibular disorders (TMD) among a sample of participants that practice choir singing as a recreational activity. As the literature shows the positive effects of choir singing on mental and physical health, we hypothesized that anxiety, stress and TMD symptoms would be less frequent in the choir group when compared to participants from the general population. The choir group included 33 adults who participated weekly in a choral singing group as a recreational activity and the comparison group included 40 participants from the general population. Choir singers had significantly lower levels of anxiety and TMD. A significant positive correlation was observed between anxiety and TMD scores. The groups did not differ regarding the presence of stress symptoms. It seems that choir singing was associated with better mental and physical outcomes. This study reinforces the promising benefits of choir singing as a recreational activity. Although we only included amateur singers in our sample, the literature shows that singing as a professional may be an etiologic factor for developing TMD. Future studies should explore differences between professional and amateur choir singers regarding TMD symptoms
