Will wearing two masks better protect me from the virus? AP Illustration/Peter Hamlin
Does wearing two masks provide more protection?
It depends, but it’s possible that doubling up could help in some situations.
The U.S. Centers for Disease Control and Prevention recommends wearing a cloth mask made with two or more layers, and ensuring it covers your nose and mouth. The agency says it should fit snugly so there aren't any gaps at the sides of your face.
Wearing just one mask should be enough for most situations, as long as it fits well and isn't loose, said Dr. David Hamer, an infectious disease expert at Boston University.
“Starting out with a good mask to begin with is going to be key,” Hamer said.
Still, some people might want extra protection if they're at risk for severe illness if infected or will be in situations where they expect to be around others for extended periods, such as on a plane.
One option in scenarios when you want extra protection is to wear a cloth mask as well as a regular surgical mask, said Dr. Monica Gandhi, an infectious disease expert at the University of California, San Francisco.
Gandhi said that combination -- with either mask on top -- could help achieve a similar effect as the N95 mask. She recommended the added protection for people who will be indoors in areas where transmission rates are high — which could reflect the circulation of more contagious variants.
Another option Gandhi and a colleague recommend for situations where you want “maximum” protection: A two-layer cloth mask that has a filter material in between.
With single cloth masks for everyday use, Gandhi noted it's important that they're made of tightly-woven material and have at least two layers, which creates “an obstacle course” that makes it harder for virus-carrying particles to break through.
In a nearly 3,700 page UN report, climate scientists outline the imminent dangers caused by climate change, saying fossil fuels are 'choking humanity.' The report calls some of the impacts of global warming 'irreversible,' warning of extreme consequences in the near future. Kristie L. Ebi, Professor of Global Health and Environmental and Occupational Health Sciences, University of Washington joined Cheddar's Opening Bell to discuss.
World leaders are currently dealing with a handful of pressing issues, including Russia's invasion of Ukraine, inflation, and not to mention the COVID-19 pandemic; but it could be argued that the most pressing issue is one that has experienced its fair share of neglect in the past -- climate change. As tensions escalate between Russia and Ukraine, there is fear the focus on climate will once again be pushed aside. However, the White House appears to be making some effort to prevent that from happening. The White House Office of Science and Technology held a first-of-its-kind roundtable discussion with some of the nation's leading climate scientists on Thursday. Michael Mann, Director of the Earth System Science Center at Pennsylvania State University, and author of the book 'The New Climate War' joins Cheddar News' Closing Bell to discuss his experience as one of the climate scientists at the White House event.
On December 25, 2021, NASA got into the holiday spirit by launching the James Webb Space Telescope, the largest and most powerful space science observatory in history.
It is intended to succeed the Hubble Space Telescope as NASA's flagship mission in astrophysics and is able to view objects too old and distant for Hubble. Gregory Robinson, director of NASA's James Webb Space Telescope program, joins Cheddar News' Closing Bell to discuss the mission. "I think a lot of what we don't know today is what I'm expecting to find and certainly really understand what took place more than 13.5 billion years ago and see the formation of some of the first galaxies in our universe," said Robinson.
The COVID-19 pandemic disrupted blood donations leading to severe shortages throughout the country. Chloe Aiello reports on the desperate need for new donors.
GSK has unveiled its new consumer health unit called Haelon. Haleon will debut as a standalone company later this year. Katie Williams, U.S. chief marketing officer at GSK, joined Cheddar News to discuss.
Even amid the Great Resignation, the cannabis industry saw major job growth. As of January 2022, the legal industry supported more than 428,000 jobs — a 33 percent increase year-over-year, according to the sixth annual jobs report from Leafly, a website focused on cannabis use and education. Yoko Miyashita, CEO of Leafly, joined Cheddar News' Closing Bell to discuss. “You know we've got big moments coming ahead in New Jersey and New York with adult-use sales starting in New Jersey, hopefully by this fall, with New York quickly to follow," she said. "So we're hugely optimistic about the kind of job growth that those markets can drive with the right type of market setup.
DNA evidence now shows that the 500-pound black bear the public had nicknamed “Hank the Tank” is, in fact, three not-so-little bears who have damaged more than 30 properties around Lake Tahoe in recent months.
The Biden administration will significantly loosen federal mask-wearing guidelines to protect against COVID-19 transmission on Friday, according to two people familiar with the matter.
