Put this in full screen. Add headphones. Sit back, and enjoy the world's most relaxing film. It might be a total placebo effect, but this worked for me!
(OK, so I can't verify that this really is the world's most relaxing film, but that's what it's titled, and I'm a sucker for this kind of marketing!! My only complaint is that if they had used the 3D audio style that @alywoah posted about, it might have been even more relaxing). It was all filmed in Denmark as a campaign to get people to visit the countryside more!
The Making Of
And they didn't just make it and hope that it would work, they actually tested it with 100 "busy, city people". Their pulses were monitored, and after having watched the 7 minutes long, relaxing film the guests’ pulse had dropped by an average of 10%, some even by as much as 25%!
Who wants to go on a trip with me to Denmark?! I'm ready!
