A new study conducted by a group of Swedish researchers suggests that choir singers not only manage to synchronize their voice with others in the group but also synchronize their heartbeats.
Researchers from Sahlgrenska Academy at Gothenburg University in Sweden observed 15 choir members performing three different types of songs and recorded their heartbeats as they sang.
AdvertisementThe researchers found that the heartbeats of the members increased and decreased at the same rate when they sang in a synchronized manner.
"When you are singing, the heartbeat for the whole group is going up and down simultaneously. It gives you pretty much the same effect as yoga breathing. It helps you relax, and there are indications that it does provide a heart benefit. We already know that choral singing synchronises the singers' muscular movements and neural activities in large parts of the body. Now we also know that this applies to the heart, to a large extent", lead researcher Dr Bjorn Vickhoff said.
