A novel study shows that facemask use does not affect indicators of cognitive performance when the wearers are resting or performing moderate physical work in hot environments. However, wearing a facemask does make it more difficult to breathe when performing moderate physical work in a hot environment.
The study is conducted by researchers at the Department of Nutrition, Exercise and Sports, University of Copenhagen in collaboration with the European research consortium ‘HEAT-SHIELD’.
Facemasks are mandatory by law in many countries and recommended by the World Health Organization (WHO) to prevent spreading of the COVID-19 virus.
