The researchers have claimed that an hour"s laughter can burn up to 100-120 calories and boost the energy a person uses use by up to 20 percent. That is the equivalent of vacuuming for 40 minutes, walking for 15-20 minutes or doing 18-27 minutes of weightlifting.
This means that a top sitcom could help an individual lose 1-2lb a month. “Laughter gets the heart beating faster and boosts blood flow," the Daily Star quoted Dr Helen Pilcher, who led the research for comedy channel G O L D, as saying.
“As you giggle and gasp for air, you breathe in more oxygen. “The chest rises and falls and abdominal muscles get a good workout," Pilcher added.
