Hamburg - Have you laughed today? Good thing if you have because most people take life too seriously.
But those who laugh are healthier because laughing helps them loosen up. Though it causes the pulse initially to quicken, its slows down considerably, so that blood pressure sinks.
"The skeletal muscles relax and the overall result is better circulation to the muscles," said psychologist Michael Titze, chairman of an association called HumourCare in Tuttlingen, Germany, and a researcher into laughter.
