Masks during exercise

According to a report in the UK Daily Telegraph French medics have criticised the requirement for runners in many French cities to wear face masks as “nonsensical”.

They argue that as the runner’s sweat seeps into the mask it impedes air flow unto the mouth and traps organic matter in the mesh of the mask, causing it to lose its effectiveness.

Masks would have to be changed regularly throughout the period of exercise to be effective. Many doctors argue that maintaining physical distance is a much more effective way of safeguarding against the spread of infection.
