Decreasing the amount of oxygen people are breathing, by forcing people to wear masks, is cruel and medically stupid, as Dr. Buttar points out. Under the mask, O2 readings drop from a regular 21 to an unhealthy 17.5, ringing the alarm of the official OSHA devices that measure such things.
The usual amount of CO2 in the air is approximately 400 ppm, when measured around the nose or mouth would be higher. But wear a mask and concentrations shoot up to 5,000. This is not healthy! Carbon dioxide in the air we breathe usually is at 0.0390 percent. When we breathe out, it is 4.0 percent. It is not the concentration we want to be breathing in.
The minimum oxygen concentration in the air required for human breathing is 19.5 percent. Approximately 78 percent of the air we breathe is nitrogen gas, while only about 20.9 percent is oxygen. The Occupational Safety and Health Administration, OSHA, determined the optimal range of oxygen in the air for humans runs between 19.5 and 23.5 percent.
Viruses of all types will get out of control in people who are vitamin D and oxygen-deficient and who are breathing back in their CO2. Add vitamin D deficiency to the mix, and we have a non-virus health crisis in the making. Its clear, no death from the coronavirus at vitamin D blood concentrations above 34 ng/ml. Light is essential; it is the backbone of life and can be used as a potent medicine against COVID-19. So keeping people indoors would never be the answer for any wise doctor.
