Flashback: CO2 affects human health at lower levels than previously thought

The researchers cited mounting evidence that CO2 levels as low as 1,000ppm can cause health problems, even if people are only exposed to them for an hour or two.

They found that CO2 levels exceeding 1,000ppm have already been observed in crowded and poorly ventilated rooms such as classrooms, offices and bedrooms as well as air-conditioned public transport and planes – all places where humans can spend several hours at a time.

Collating the findings of numerous studies, the academics summarised that acute exposure to high CO2 levels can have ‘adverse health outcomes’, citing studies which observed inflammation and reduced cognitive performance above 1,000ppm.

Chronic exposure to levels between 2,000ppm and 3,000ppm can have even worse impacts as this was linked to effects including kidney calcification and bone demineralisation.

...thus meaning wearing a mask is catastrophic for health:
