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.

During testing, body temperature and thermal discomfort did increase in both trials, but not to a greater degree while wearing a mask. However, the study also showed that wearing a facemask does make it more difficult to breathe when performing moderate physical work in a hot environment.

Eight healthy, active males, aged 27 - 41, participated in the study. On two different occasions, one with a facemask and one with a bare face, participants sat in a climatic chamber regulated at 40°C and 20% humidity for 30 min to become accustomed to the testing conditions. After which they exercised for 45 minutes at an intensity that simulates occupations with manual work.
