Dear all,

Watch the video to make your own decision whether to wear mask or not.

As you’ll see in the video above, the president of the association, Kazuhiro Tateda, explains that when we talk, we also emit invisible micrometer particles. Micro-droplets if you will. These tiny particles are smaller than the cough droplets, and gravity won’t pull them down. As a result, they can stay in the air for a longer stretch of time, and they can reach you with greater ease, especially if you’re not covered by protective gear.

To prove the theory, NHK and a group of researchers used a high-sensitivity camera and laser beams to record droplets’ behavior during a sneeze and during a regular conversation. The clip shows that large droplets fall to the ground after a sneeze, while micro-droplets persist in the air.

More interestingly, these micro-droplets appear on film even during conversation. They’re so small that you can’t see them with the naked eye. Therefore, you wouldn’t realize the danger you might be exposed to. The researchers have no idea how many such micro-droplets you’d have to inhale to get COVID-19, but they can’t rule out the risk of getting the disease that way.

The researchers simulated what happens with a cough in a closed room, and concluded that the micro-droplets could persist in the air for up to 20 minutes. Everyone in that room would be exposed to them.

The video also shows that a simple solution like opening the window and creating a draft would be enough to prevent the stagnation of micro-droplets. The video also proves that social distancing is one of the best things you can do to minimize the risk of infection.

Thank you
