Watch: A Slow-Motion Sneeze Looks A Lot Like Breathing Fire

It not rocket science but this MIT Research Group proves why covering your mouth before sneezing is so important.












To a mathematician, it’s a violent explosion that shoots out missiles of hot, wet air, slamming a turbulent cloud of moisture into anybody or anything that crosses its path.

To the rest of us, it’s a sneeze.

And Lydia Bourouiba has made a career out of studying it. Bourouiba, a mathematical physicist, leads a research group at the Massachusetts Institute of Technology that studies fluid dynamics. On Wednesday, her team published a slow-motion video of a sneeze in the New England Journal of Medicine.

It’s mesmerizing. It’s also important.

“Respiratory infectious diseases still remain the leading infectious diseases in the world,” Bourouiba explains. Many of them hop from person to person in coughs and sneezes, or “violent emissions,” as she calls them. If she can understand how a sneeze moves, she says, she can better understand how to prevent microbes from moving from a sick person or contaminated surface to somebody else. Read full story….
