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.
A new study has been causing a lot of buzz in the cannabis industry. Researchers from Oregon State University found that compounds in cannabis could prevent infection with COVID-19, but that doesn't mean smoking marijuana prevents people from getting infected. CV Sciences medical advisor Dr. Michael Lewis joined Cheddar News' Closing Bell to discuss.
A new study published in "JAMA Pediatrics" looked at how staying home impacted the mental and physical health of students during the pandemic. The results from 11 different countries found across the board that children's mental health was affected, with increased depression and symptoms of anxiety. Cheddar News speaks with clinical psychologist Eileen Kennedy-Moore on how parents can best decide on whether to send their kids back to the classrooms during the surge of Covid-19 cases.
Food waste is a major contributor to greenhouse gas emissions in the United States. Strella Biotechnology is trying to solve the problem by introducing new technology to a business that's been around for generations -- farming. The 24-year-old CEO created hi-tech sensors that interpret the shelf life of produce and alert farmers when fruits and vegetables are ready to be sent to supermarkets. The company says the process can help farmers make money, reduce food waste and increase the quality of produce. Strella Biotechnology's co-founder and CEO Katherine Sizov and co-founder and COO Jay Jordan joined Cheddar Climate to discuss.
Adele Shraiman, Campaign Representative for the Sierra Club’s Fossil Free Finance Campaign, joins Cheddar Climate, where she explains how Wall Street and climate change are related. She also elaborates on how decisions made by financial institutions are actually hurting the ability to reduce carbon emissions.
Two reports from NASA and NOAA say that 2021 was the Earth's sixth-hottest year on record, part of a seven-year streak of the hottest years reported since the data has been recorded. Meanwhile, the U.S. experienced 20 separate billion-dollar climate-related disasters, including Hurricane Ida which cost $75 billion in its aftermath. These trends are moving upward at the same time. What could be in store for 2022? Chelsea Harvey, a reporter for E&E News, joins Cheddar Climate to discuss these federal reports, the monetary impact of climate disasters, and more.
Breakthrough Energy Catalyst, a private-public fund backed by Bill Gates, is planning to invest up to $15 billion in clean technology initiatives across the U.S., UK, and European Union. It will target four key areas and help fund large projects that otherwise would not be financially possible. Bobby Hollis, Director of Breakthrough Energy Catalyst, joins Cheddar News' Closing Bell to discuss.
Washington Post Climate Reporter Sarah Kaplan joined Wake Up With Cheddar to discuss a stark climate report that definitively shows the earth is getting warmer.
Chicago schools opened their doors again following a dispute between the teachers union and the city over as the omicron variant continues to surge, but the safety issues they fought over weren't just limited to the Windy City. Dr. Bayo Curry-Winchell, family medicine and urgent care doctor, joined Cheddar in discussing concerns of parents, teachers, and students as schools try to operate amid COVID and noted what she's been observing as the number of infections among children rises. "I am seeing them contract the illness from so many different aspects," she said. "It could be from a fellow classmate. It could be from a parent. All of those things really play in the effect of transmission as well as contracting the illness."
One startup is working to reverse climate change one seed at a time. Terraformation is a global forest accelerator that provides tools, training, financing, and business support to help scale forest restoration projects worldwide. Forests naturally absorb carbon and Terraformation says that reforestation is a safe, low-cost, and scalable solution to the climate crisis. Yee Lee, VP of growth at Terraformation, joins Cheddar Climate to discuss.
