Sneezing In To Your Elbow Is the Right Thing to Do


As kids we’ve often heard our mother’s say sneeze in t your elbows rather than the palm of your hands. That is because you tend to come in contact with plenty of objects throughout the day and you can avoid spreading your germs to someone else. The researchers at the Massachusetts Institute of Technology [MIT] now have a plausible reason as to why one should sneeze into their elbows even if no one is around. What they discovered was that the virus droplets expelled through the air, when you cough or sneeze, travelled in an invisible cloud-like structure that travels up to 200 times faster than if they had to be individual particles moving by themselves.


This cloud-like structure could hang freely suspended in the air for several seconds before it possibly affect someone passing by. This was according to the research published by them in the April use of the Journal of Fluid Mechanics. It could even make its way to currents created by heating or cooling units before the droplets evaporated. The researchers studied this with the help of images. They took these high-speed imaging photos of people coughing and sneezing. They then examined and analyzed them in the lab and conducted various other experiments via simulations and mathematical modeling. This helped them figure out how the cold virus travels and track its journey from the time it leaves your nostrils. It was found contrarian to previous theories, where it was believed that smaller mucus drops travel further than larger ones.

“When you cough or sneeze, you see the droplets, or feel them if someone sneezes on you,” study coauthor John Bush, a professor of applied mathematics at MIT, said in a statement. “But you don’t see the cloud. The influence of this gas cloud is to extend the range of the individual droplets, particularly the small ones.”
