ランニング用、ネックゲイターマスクで飛沫は細かくなってマスクしないときより拡散!

The most effective mask was the fitted N95. Three-layer surgical masks and cotton masks, which many people have been making at home, also performed well.

なっ、布マスクも効くんだよ。


 Neck fleeces, also called gaiter masks and often used by runners, were the least effective. In fact, wearing a fleece mask resulted in a higher number of respiratory droplets because the material seemed to break down larger droplets into smaller particles that are more easily carried away with air.

Folded bandanas and knitted masks also performed poorly and did not offer much protection.

"We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask," Fischer said. "We want to emphasize that we really encourage people to wear masks, but we want them to wear masks that actually work."

 山中さん自身は「走るときにマスクをすると、顔にくっついてしまって苦手」という。代わりに、薄手で伸縮性のある「ネックゲイター」の使用を勧め、鼻と口まで覆う使い方を実演。「マスクの出来上がり。普通のマスクよりも十分快適に走ることができると思う」と語った。


訂正したほうがいいでしょ、これは。影響力大きい方だから。
