London - Singing - in a choir boosts the immune system and could even help the body fight cancer, according to research.
Scientists found that just one hour of singing significantly increased levels of immune proteins that the body uses to battle serious illness, and dramatically reduced stress hormones, such as cortisol.
Doctors believe this takes strain off the immune system, allowing it to use its resources better.
The research, published in journal ECancer Medical Science, raises the possibility that singing in a choir could put cancer patients in the best possible position to receive treatment and stop tumours returning.
Scientists at Imperial College London, University College London and the Royal College of Music tested the saliva of 193 members of five different choirs in Cardiff, Bridgend, Pontypridd, Cwmbran and Swansea before and after singing sessions. Of the participants, 55 had cancer.
Diane Raybould, 64, a breast cancer patient who took part in the study, said: “Singing in the choir genuinely makes you feel better.”
