Scientists agree that coronavirus is mainly widespread droplets released whenthe infected person toughered, talks or sneezing. That's why health agencies around the world have recommended the use of facial masks as an effective way to stop the pandemic. But there is another daily article that probably comes to hang out in your unwanted drawer for the moment that could be another answer tostop covid of propagation:lip balm.

The discovery comes from new research carried out by scientists in France and the United States, published in the journalAmerican physical societyOctober 2nd 2. The study used high speed video recordings ofSubjects speaking various sounds Determine how potentially infected droplets are expelled from someone's mouth. Visual evidence shows thatLip movements Made to form the consonant sounds lasting "p" and "t" generates the largest number of droplets - but that the lip balm can help reduce the amount of droplets expelled.

The study revealed that the saliva based on the edges of the lips creates ropes, or "filaments" that propagate through the opening of the mouth when it is open and closed, creating droplets when breathing wears the saliva of the mouth in the air. However, scientists have discovered that lip balm makes it difficult for the formation of filaments on the mouth. In fact, research has shown thatUse a lip balm Cut the number of droplets down four times compared to non-hydrated lips.

The results are so surprising that the authors of the study conclude that the use of a lip balm could be a cheap and effective solution for slowing the propagation of the virus, especially in the coming winter months when People - and their dry lips, spend more time inside.

The study is not the first to examine the way the droplets bearing coronavirus can be propagated according to certain movements of the lip. A study published on September 25 in theActs of the National Academy of Sciences Also used a high speed camera to film the movement of the droplets being propagated from aperson speaking several different sentences. They looked at the droplets propagated from short statements, like "we will fight coronavirus", rhymes of an alliterative nursery, like "Peter Piper chose a peck" and "sings a song of Sixpence."

The study concluded thatSome statements broadcast more droplets that others. Researchers in this study also found that the sound of theLetter "p" creates puffs of air In front of the speaker, while an entire statement using "P" sounds, such as "Peter Piper has chosen a peer," created what researchers called a whole "puff train", increasing the chances of Covid transmission.
