Correlation not causation. No doubt it would have an effect but it's ridiculous to say that it would have a greater effect than masks without data.

In an ideal world where everyone were fit with strong immune systems, the threshold of dying from covid would be more similar to that of the flu--you wouldn't need to wear a mask for the same reason you wouldn't need to wear one for the cold and flu season. (That said I'm not against masks. We should have been wearing them for cold and flu seasons this whole time.) It's causation, not just correlation. If you want an explanation, here's what physicians say: > Then, there is Newton's second law: force = mass × acceleration. It requires more muscle force to displace the diaphragm downward when a substantial fat mass lies below it. Abdominal obesity also makes it more difficult to breathe in a prone position that is favored to improve ventilation in patients with COVID-19. Among more specific mechanisms is expression of angiotensin-converting enzyme 2 protein in adipose tissue. This is the docking protein for SARS-CoV-2 to enter a cell, and fat has higher levels than the lungs and so may serve as a viral refuge and replication site, prolonging virus shedding. https://www.acpjournals.org/doi/10.7326/M20-5677 https://www.acpjournals.org/doi/10.7326/M20-5677
