The World Health Organization is adamant that: “People should NOT wear masks when exercising, as masks may reduce the ability to breathe comfortably”; and “Sweat can make the mask become wet more quickly which makes it difficult to breathe and promotes the growth of microorganisms.” The WHO recommendation is to maintain at least one-meter physical distance from others.
But there are also strong arguments for challenging the WHO’s advice. The main one being that the National Health Service in the UK is truly overwhelmed for the first time in its 70-year history because of the rise in COVID hospital admissions. All possible measures must be taken to reduce these numbers.
England is deep into its third lockdown, yet the daily tally of new COVID cases and deaths remains sickeningly high. As Chris Whitty, the country’s chief medical officer, said recently, more needs to be done to bring the pandemic under control.
