Today Komatsu introduces a daily action - sneezing. What is the action of sneezing?
Advanced explanation of sneezing
Every sneeze is a "hitchhiker" of germs and bacteria
People often cough and sneeze during respiratory diseases, and a large proportion of respiratory diseases are caused by viruses and bacteria. When coughing and sneezing, a lot of saliva fluids and droplets will be spewed out at high speed. Viruses or bacteria will also ride on the "hitchhiker" of these saliva to fly with the wind, spread, spread, and spread again. More critically, these saliva fluids and droplets can spread far and wide, not just between the fingers.
The video is 0.34 seconds after a person sneezes, and after the instrument sees the spread of spit, we can see that in the 0.34 seconds that cannot be covered, the saliva has spread to 70 centimeters away. Because of this, when we cough and sneeze, we must cover our mouths to avoid spreading diseases.
Why don't you use your hand to block sneezing?
We can imagine if you cover your mouth and nose with your hands when you have a cold and sneeze, it does block the spread of droplets into the air, but the virus quickly runs to your hands with your spit, and the temperature of the human hand is just right for the virus to survive, the terrible thing is that it can survive for 3 hours, if you do not wash your hands, eat or touch your nose and mouth, the virus then runs back to your mouth. After a cycle, the virus all went back.
What's even more frightening is that if you don't wash your hands in time and touch public objects such as stair railings and bus handrails, you will spread the virus to these items, which will easily spread the virus to others.
The right way to sneeze please keep in mind
Sneezing experiments by authoritative institutions have proved that the tightness of the hands is not as tight as the sleeves, and the best way to cover the mouth with your elbows when coughing or sneezing. This is a better way to avoid the spread of disease, protect family, friends and more people.
