Everyone immediately thinks of air pollutants when hearing "poor air quality." However, this is just part of the whole picture. We must detach ourselves from the misconception that only substances identified as harmful in the air can pose a problem. In science, there's a tendency to look for symptoms triggered by individual "toxic" substances in the air. NO2, for instance, is considered highly toxic. Certainly, it is, but even completely harmless substances can be dangerous and unhealthy in the wrong amounts.

Although we cannot live without oxygen and no one assumes oxygen can be harmful, it has been proven that more than 50% oxygen in the breathing air can cause severe physical damage through oxidation over the long term. This also applies to other substances in the air. Too much is always unhealthy.

The most important discovery we have made in recent months is the fact that we absorb more substances through our lungs than through eating. Oxygen and CO2 alone, by mass, are more than all the food and drink we consume in the same period. It's important to know that not everything we inhale also exits our body via the lungs. Much of it enters the bloodstream and is further processed by the body. Whether the body needs the substance or not is regulated by biochemical processes. Anything unnecessary must often be transformed by other substances in the liver or kidneys so that the original substance can be expelled from the body through the lungs, stomach, intestines, or bladder.

Energy and the right substance for transformation are required for all these processes, thereby straining our entire body. Regardless of what exactly is in the breathing air, it becomes clear that all of it can burden the body.

The biggest problem in our modern life is that we spend so much time in enclosed spaces. There, all sorts of substances accumulate in the air and can only be reduced with difficulty even by ventilating. Everything in our home emits some substances. Although these are mostly non-toxic in principle, the total amount that accumulates indoors over the years poses a serious health problem. Additionally, other pollutants, generated by combustion processes in our environment, accumulate as well. We are thus constantly living in an environment where too much of various substances is present in the air.

Invisible and, due to our habituation to these substances, no longer smellable.

This is comparable to being constantly surrounded by food and stuffing it into ourselves uncontrollably, hoping it exits the body as quickly as possible. We all know what would happen then. Through the lungs, we cannot consciously decide not to breathe something in. Otherwise, we would unfortunately suffocate. So, the only option is to reduce everything that is too much in the air as much as possible.
