One hour of this type of singing can improve mood, immune function and more…

Singing in a choir for only one hour can improve mood, reduce stress and even boost immune proteins, a new study finds.

The largest improvements in mood were seen among those suffering with the greatest level of depression and lowest mental wellbeing.
The research involved 193 people whose lives had been touched by cancer and who were members of five different choirs.
Dr Ian Lewis, one of the study’s authors, 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.”

Dr Daisy Fancourt, the study’s first author, said:
“Many people affected by cancer can experience psychological difficulties such as stress, anxiety and depression.
