Actually, the humor in this tip is practically nothing. Message about the benefits of laughter quite seriously listened to 2,000 delegates from 80 countries participating in the 4-day European congress on obesity, quit in Athens June 4, 2005. The report's author - Matej Bachovski, American Associate Professor of Polish origin, who works at Vanderbilt University Medical Center. He believes that together with his colleagues was the first who decided to find out how much energy is required to ensure that laugh. "We discovered that laughter produces energy," - said the scientist. So, if you believe Bachovski, 10-15 minutes of genuine laughter can burn calories equivalent to a chocolate bar of medium size. In order to find out, we had to experiment with, as usual, volunteers from the students. The researchers invited about 100 volunteers - 45 pairs of friends. Young people were shut in a room that looks like a room in a cheap hotel. In fact - it was a so-called metabolic chamber. It determines how much oxygen a person inhales, and how much carbon dioxide he breathes out - thus, the scientists measured the power consumption. In addition, the room has the equipment that monitors heart rate, and conducted a record of all sounds. Volunteers were seated in a chair watching television, have banned the move and speak, so they do not waste energy in vain. At the same time they were misled - said that the aim is to study the emotional reactions to various videos. "It's not so easy to catch genuine laughter - explained Bachovski. - Because if you say to people that are going to measure laughter, they will laugh. A specially induced laughter is regulated by a totally different part of the brain. We wanted to laugh was genuine." The first thing needed to know rates of metabolism - metabolic rate of students staying in the relaxed state. Scientists have shown them the English countryside: "First you need to have half an hour of something boring, so we have chosen English landscape", - said the doctor. The next phase for each group of volunteers lasted more than an hour. On the screens they saw a 10-minute piece of comedy, then - 5 minutes wistfully wandering sheep, then another 10 minutes of comedy and so on. The researchers separately tested seven pairs of male friends, 17 pairs of girls and 21 mixed couple (like detect differences). In the end, the data on heart rate, recorded laughter and breathing information were assembled in the laboratory and carefully analyzed. It turned out that the young people laughed more than girls. The longest laughter lasted 40 seconds. And scientists have found that when people laugh, there is approximately a 20 percent increase in metabolic rate. "Laughing, the students burned 20% more calories - said Bachovski. - Then we tried to figure out what would happen if someone will be laughing for 10 or 15 minutes a day, and found that would burn up to 50 calories, Depending on body size and intensity of the laughter. According to our calculations, for the year laughter can help you lose up to 2 kilograms, if you're having fun every day. " Laugh, mind you, definitely need a voice, loudly. Otherwise they will not work. True, it is unclear who or what might trigger a daily 15-minute session of laughter, says MEMBRANA.RU.
