Sign up for the Nature Briefing newsletter what matters in science, free to your inbox daily. Similar results were also shown in studies with mouthguards where a slightly increased RAW and reduced respiratory parameters were observed at rest and during exercise16. Healthcare workers providing direct care or working within the patient/client/resident zone for individuals where assessment suggests a high-risk of transmission, should use P2/N95 respirators rather than face masks, along with the other PPE required.
