Before the pandemic happened, wearing face masks for some people is just an accessory to their ootd, especially for countries where wearing one in public is not part of their culture. (Because they believe only those who are sick should wear one. And so when they see you wearing one, they'll move away from you.) Now that wearing masks is mandatory and part of the norm, most of us are still adjusting being comfortable going outside wearing one.
Doing tiring activities while on face masks must be done with caution because it might lead to serious health problems like the man from China who became breathless and got his left lung punctured because of jogging while wearing mask. A few days ago, I came across this article featuring an idea of Japan to create a much breathable face masks will help people feel at ease while still protecting themselves from the virus. These face masks, however, are not made due to the case in China but due to the increasing temperature in Japan as summer approaches.
I think this is a really "cool" invention and must be used by people around the world too. 🙂
