The research raises the possibility that singing in choir rehearsals could help to put people in the best possible position to receive treatment, maintain remission and support cancer patients.
The study tested 193 members of five different choirs. Results showed that singing for an hour was associated with significant reductions in stress hormones, such as cortisol, and increases in quantities of cytokines — proteins of the immune system — which can boost the body’s ability to fight serious illness.
Dr Ian Lewis, Director of Research and Policy at Tenovus Cancer Care and co-author of the research, said: “These are really exciting findings. We have been building a body of evidence over the past six years to show that singing in a choir can have a range of social, emotional and psychological benefits, and now we can see it has biological effects too.
“We’ve long heard anecdotal evidence that singing in a choir makes people feel good, but this is the first time it’s been demonstrated that the immune system can be affected by singing. It’s really exciting and could enhance the way we support people with cancer in the future.”
Choir members gave samples of their saliva before an hour of singing, and then again just after. The samples were analysed to see what changes occurred in a number of hormones, immune proteins, neuropeptides and receptors.
Diane Raybould, 64, took part in the study and has been singing with the Bridgend Sing with Us choir since 2010. Diane was diagnosed with breast cancer when she was aged 50. Her daughter was diagnosed with breast cancer at the same time and sadly, passed away from the disease at just 28. Diane said: “Singing in the choir is about more than just enjoyment, it genuinely makes you feel better. The choir leaders play a huge part of course, but so does the support of the other choir members, the inspirational programme and uplifting songs. The choir is a family, simple as that. Having cancer and losing someone to cancer can be very isolating. With the choir, you can share experiences openly and that is hugely important.”
Rosie Dow, Head of Sing with Us at Tenovus Cancer Care and co-author of the research, added: “This research is so exciting, as it echoes everything all our choir members tell us about how singing has helped them. I’ve seen peoples’ lives transformed through singing in our choirs so knowing that singing also makes a biological difference will hopefully help us to reach more people with the message that singing is great for you — mind, body and soul.”
