Researchers at the University of Cambridge have been testing it in university students. They've shown that when people are on the boat, definitely their heart rate goes down. And then what happens when they go into the dungeon is a bit more mixed. So some people seem to be able to remember to do the breathing and it does reduce their heart rate. Other people are less able to kind of implement it in that stressful situation. The research is very clear that this would never be a replacement for traditional therapy.
