Yoshihara examined 4 sorts of face masks: a surgical masks; an N95 respirator; a gaiter, which covers the neck and goes over the nostril and mouth; and a sport masks. None of them considerably elevated physique temperature or coronary heart fee in comparison with the group with out a face masks.
As suggestions modified quickly over the course of the pandemic and differed throughout organizations and geographic areas, there was a big want for scientific steering. This examine is the primary to supply proof to show that masks don’t add any threat to well being when worn throughout train within the warmth.
Contributors walked or jogged for 60 minutes in a 90 degree-Fahrenheit atmosphere at low to average train intensities.
“Earlier than this examine nobody knew if sporting a masks within the warmth would add further stress to an exercising particular person. Whereas we all know masks are necessary to stop transmission of COVID-19, we did not know if exercising with a masks within the warmth, the place your physique is already managing further stressors, would influence security,” Yoshihara says.
Yoshihara and her crew additionally measured the humidity and temperature inside and out of doors of the face masks. They positioned a sensor inside and out of doors of the facemasks on individuals’ faces.
They discovered the game masks and gaiter turned considerably extra humid because the supplies absorbed extra sweat and water vapor from exhaled air.
Whereas individuals did report a higher diploma of respiration discomfort throughout train with a facemask due to the modifications in humidity and temperature inside the face masks, there was no relationship between reported discomfort and measures of physique temperature and coronary heart fee.
Yoshihara hopes this analysis may also help form tips for athletes who’re exercising and competing throughout the summer season and into the autumn whereas ambient temperatures are nonetheless excessive, particularly as vaccination charges outdoors the U.S. stay low.
“It is possible and secure to make use of masks throughout low to average depth train within the warmth,” Yoshihara says.
Whereas this examine didn’t have a look at how effectively these masks forestall the unfold of COVID-19, Yoshihara says this can be a future space of examine she is desirous about investigating.
