Choir singers' heartbeats synchronize

When some choirs sing, the individuals' heart rates quickly synchronize. Researchers from the University of Gothenburg in Sweden monitored the pulse of high school choir singers and also found that when the choir began to sing, their unified voices caused their heart rates to slow.

"When you sing the phrases, it is a form of guided breathing," project leader and musicologist Bjorn Vickhoff told National Public Radio. "You exhale on the phrases and breathe in between the phrases. When you exhale, the heart slows down… The members of the choir are synchronizing externally with the melody and the rhythm, and now we see it has an internal counterpart."

  1. Yes, the BBC also used this "Synchronize Their Heartbeats" phrase in their headline. When you read the content, it's far less exciting. Heartbeats do not synchronize - that would really be news - and it lured me to click to the article. Rather, heart RATES go up and down together (nor do the absolute rates match). This is attributed to the known fact that heart rate changes during in-breaths (faster) and out-breaths (slower). To me it looks like the only news here is that choir members inhale and exhale together.
