Researchers analyzed the CO2 content of inhaled air among children wearing two types of masks, as well as wearing no mask
CO2 in inhaled air under surgical and filtering facepiece masks came in between 13,120 ppm and 13,910 ppm; the German Federal Environmental Office set a limit of CO2 for closed rooms of 2,000 ppm
Younger children appeared to have the highest CO2 values; a level of 25,000 ppm was measured from a 7-year-old wearing a facemask
The researchers believe the use of facemasks could lead to “impairments attributable to hypercapnia,” which is a buildup of CO2 in the blood
Children wearing facemasks at school have reported symptoms such as shortness of breath, dizziness, headaches, irritability, fatigue and difficulty concentrating
Mandating children to wear facemasks for long periods of time while at school and participating in other activities is an unprecedented move, one that was put into place despite no research showing the practice is safe. It’s not simply a case of “something is better than nothing,” because the act of mask wearing comes with a risk of adverse effects.
Now that the pandemic is more than a year behind us, evidence is starting to accumulate showing that the use of face masks in children may cause more harm than good. One of the latest studies noted that the evidence base for making face masks compulsory in schoolchildren is “weak,” and looked into their effects on carbon dioxide in inhaled air.
