Absolutely breathtaking (new review):

In reliable human experiments face #masks lead to 1.41–3.2% carbon dioxide breathing, exceeding both NIOSH limits for CO2 respiration:

-acute limit for 15 min: 3% CO2

-chronic limit for 8 h:: 0.5% CO2

2/6🧵
Regarding CO2, circumstantial evidence exists that mask use may be related to current observations of a significant rise of 28% to 33% in stillbirths worldwide and a reduced verbal, motor, and overall cognitive performance in scores in children born during the pandemic

3/6 🧵
A significant increase in CO2 body levels in mask wearers under various conditions has been demonstrated by many scientific intervention studies

4/6 🧵
According to these data, wearing face masks has the potential to exceed acute (3% CO2 for 15 min) and chronic (0.5% CO2 for 8 h) NIOSH limits for CO2 respiration.
This causes toxicological risks of carbon dioxide rebreathing for particularly vulnerable groups.

5/6 🧵
Animal experimental data shows deleterious proven effects of elevated CO2 of inhaled air with threshold values of above 0.3%, 0.5% and 0.8% (Neuron destruction, impaired memory and learning, increased anxiety, destruction of cells in testes, stillbirth, and birth defects).

5/6 🧵
in view of the limited scientific evidence for masks as an effective pandemic measure (SARS-CoV-2), there is need to re-evaluate and reconsider mask mandates especially for vulnerable subgroups (pregnant, children and adolescents)
