Good Lifestyle

If you like to stay indoors with your air conditioner on wet days, you may save more than sweating through your clothes. There is evidence of assembly thatwet air is particularly welcoming for COVID particles. In fact, a new study published today in the journalFluid physics found that the amount of water vapor in the air affects how longRespiratory droplets can live. Thanks to the modeling, the researchers have discovered that the expelled respiratory droplets (which can be infected with COVID) can accommodate up to 23 times longer in high humidity.

To be exact, 50 micron droplets expelled in 95% moisture have lived up to 23 times longer in the air than those expelled in a 0% moisture. This is because the droplets evaporate faster when there is less water vapor in the air. This was particularly true of smaller droplet researchers, compared to those who were 100 microns.

It is important to note that the study did not specifically dealt with coronavirus infected droplets and there are still many unanswered questions about howCOVID TRANSMISSION AIRBORNE works. But we know that carrier respiratory droplets (whether symptomatic or not) areCharge of virus particles. TheFluid physicsThe study suggests that these particles can fly in the air a lot longer on wet days than as opposed to evaporating or falling rapidly on the ground.

In the study, moisture has also affected the distance from the droplets of the source. Small droplets have traveled up to 16 feet of 100% moisture, compared to about 11 feet of 50% moisture. And when the researchers simulated a "jet of cough", they found that the percentage of expelled respiratory droplets that evaporate or fell immediately to the ground diminishing as moisture decreased.

"If the virus load associated with droplets is proportional to the volume, nearly 70% of theThe virus would be deposited on the ground during a cough, "the author of the study,Binbin Wang, PhD, says in a statement. "Maintaining physical distance would significantly consolidate the spread of this disease by reducing droplet deposits on people and reducing the probability of inhalation of aerosols near the infectious source."

However, the relationship betweenRespiratory moisture and droplets is complicated and there are several factors to consider. In June,Bromage Erin, PhD, Associate Professor of Biology at the University of Massachusetts, Dartmouth, told CNN thatHigher moisture can cause larger droplets To fall faster, but the danger would then be in them landing on surfaces and remaining infectious. At lower humidity, the droplets remain smaller, which can keep them in the form of altitude longer. "There is a kind of" Goldilocks "area for coronavirus, between 40 and 60 years old [as a percentage] moisture, where it will not survive for a very long time," said Bromage.

While the pandemic continues, we will probably see much more research on how moisture and other environmental conditions affect transmission. And for more on what we know so far,Dr. Faisci has just confirmed that this only thing kills coronavirus.
