What if bad air learns along with us?
When children or adults have trouble concentrating, we usually look for the causes in motivation, talent, sleep, media use, stress, or personal weakness. Hardly anyone thinks first of the room itself. And yet we spend a large part of our lives in classrooms, offices, training rooms, and apartments, exactly where thinking, learning, and mental performance are supposed to take place.
That is why in Dicke Luft we ask a question that is far too rarely asked in everyday life: what if the air in indoor spaces affects learning and concentration more strongly than we realize?
School Should Make Learning Possible, Not Harder
In the book, we describe how self-evident the idea once was that fresh air makes learning easier. Rooms were aired out between lessons so stale air could leave and new air could come in. At the same time, our own story shows how quickly this knowledge disappears in everyday life. Windows stay closed because it is too noisy, too cold, too warm, or too windy. And at some point it becomes normal to spend many hours in rooms where no one seriously asks what that air is doing to attention, mood, and mental performance.
When Concentration Slowly Disappears
One central motif of the book is the experience that concentration problems often do not begin like a dramatic collapse, but gradually. The book describes how, when there is too little fresh air indoors, oxygen deficiency does not occur first. Instead, the CO2 concentration rises much more quickly. With it can come tiredness, pressure in the head, declining thinking ability, mental slowing, inner restlessness, and emotional irritability. Precisely because these complaints develop gradually, they are often not linked to indoor air, but to effort, overload, or personal weakness.
That is exactly where the problem lies: what we interpret as lack of motivation, distractibility, or poor discipline could in some situations also be an effect of poor indoor air.
The Classroom as an Underestimated Factor
In the book, we portray school life as many hours spent in closed rooms, with fixed routines, limited air exchange, and lessons under conditions that hardly anyone systematically questions. Headaches, tiredness, and concentration problems appear early on. Later, it is described how, at secondary school, airing out rooms often stopped completely, even when many students were already complaining about stuffy air. The complaints were still interpreted differently, as sensitivity, an eye problem, boredom, or personal weakness.
That is what makes the topic so explosive. If learning problems are in reality partly caused by the room, the child is often declared the problem even though the room itself may also be one.
Why This Topic Matters So Much to Us
Learning and concentration are not purely inner achievements. They never arise only in the head, but always in an environment as well. If children become tired in stuffy classrooms, adults can no longer follow discussions in meetings, or pressure in the head, a feeling of cold, and confusion suddenly spread in training rooms, then air must finally be taken seriously as a real influencing factor. The book describes exactly such situations and the unsettling fact that those affected are often considered the problem themselves.
Perhaps Part of the Problem Lies in the Room
We are not claiming that poor grades, concentration disorders, or learning difficulties are generally caused by indoor air. It is not that simple. But Dicke Luft suggests that indoor air could be an underestimated amplifying factor, in schools, in education, in offices, and everywhere people are expected to remain mentally productive for hours.
Perhaps part of what we interpret as tiredness, unwillingness, or lack of concentration does not lie only in the person. Perhaps part of it also lies in the room.
