We told them so! COVID face masks linked to seizures, cancer; Mask study published by NIH suggests N95 Covid masks may expose wearers to dangerous level of toxic compounds linked to seizures & cancer

study published in April found disposable masks can have toxic chemicals Experts said this could make newly instated mask mandates ineffective; masks raise risk of stillbirths, testicular dysfunction

‘Face masks may raise the risk of stillbirths, testicular dysfunction and cognitive decline in children, an 'explosive' new study has claimed.

Authors of a review of dozens of studies on face coverings suggested they can cause mild carbon dioxide poisoning when worn over long periods.

The German academics who carried out the research believe masks create a pocket of dead space between the mouth and mask, which traps the toxic gas.’

The surgical N95 mask has been held up as the gold standard when it comes to protecting against Covid. 

But a study quietly re-shared by the National Institutes of Health in spring suggests the tight-fitting mask may expose users to dangerous levels of toxic chemicals.

Researchers from Jeonbuk National University in South Korea looked at two types of disposable medical-grade masks, as well as several reusable cotton masks.
