New study measures distances traveled by exhaled breath to assess benefit of wearing a mask. FMTNews FMTLifestyle Covid19 Mask Health
EDINBURGH: New UK research has found that wearing a face mask could reduce the spread of Covid-19, although choosing one which fits your face will be even more effective.
Measurements were taken from people wearing different face coverings while standing or lying down, and also from a mannequin that was connected to a cough-simulating machine. However, the fact that the valves on these masks are there to make breathing easier also means they could allow infectious droplets to travel quite far in a forward distance, say the researchers.
Co-author Dr Cathal Cummins commented on the findings saying, “Even our handmade mask performed very well in preventing the frontal spread of the wearer’s exhaled breath.
