Fatigue / Yawning

Did you know that yawning is not necessarily a sign of tiredness, but rather can indicate a gas imbalance in the bloodstream?

We yawn both in response to a lack of oxygen and sudden changes in air composition, in order to balance the ratio of O2 to CO2 in our blood.

This imbalance leads to fatigue, which is often a sign of high CO2 concentration in the air we breathe.

According to our observations, especially younger people start yawning and feeling tired at CO2 concentrations of about 700 to 800 ppm without physical activity (e.g., while sitting or standing).

(Personal opinion, scientifically the cause of yawning is still unknown.)

Stress

CO2, NO2, and ozone can cause oxidative stress in the body. Although this phenomenon is often mentioned in advertising in connection with nutrition, air pollutants have a significantly greater impact on oxidative stress than food.

This stress can lead to a variety of other symptoms and physical problems. Based on our experience, a CO2 concentration of 700 ppm overnight, or more than 800 ppm for half an hour, can lead to oxidative stress, which can manifest in inflammation, gastrointestinal problems, or inner restlessness.

vision disturbances

The variations of vision disturbances are diverse and vary from person to person.

The eye, which requires the most oxygen after the brain, already reacts to the slightest amounts of CO2 and NO2 with various disorders. The retina, in particular, is very sensitive to air pollutants.

A noticeable symptom, for example, is the sensation of sand in the eyes, even though this is not actually the case. This sensation can often indicate a lack of oxygen, as the eye can convey only a few sensations. Doctors often diagnose "Dry Eyes" in such cases. However, based on our personal experience, improved air quality in the room is more effective than other treatment methods.

Another symptom of acute oxygen deficiency is double vision or suddenly blurred vision.

With chronic exposure to high concentrations of NO2 or CO2, there can be a decrease in visual acuity, deterioration of night vision, and increased sensitivity to glare. Additionally, tolerance to bright light decreases.

At night, this can lead to faster glare while driving and generally poorer vision in low light conditions.

(Scientifically, it has been proven that CO2 and NO2 cause visual disturbances and that the Eye is sensitive to decreased O2 levels.

Concentration Issues

Concentration disturbances can occur at much lower CO2 levels than previously thought, particularly in still air conditions and during periods of low physical activity, such as in a cinema, office, or classroom.

Due to limited movement, the CO2 concentration from one's own breath can quickly rise above 2000 ppm, as the air does not circulate efficiently in the space. Thus, concentration problems can arise at CO2 levels in the room air of about 600 ppm and above.

In a classroom with closed windows, the CO2 level can reach over 1000 ppm after about 5 minutes. In a home setting, possibly with two people, this level could be reached within 5 to 10 minutes.

(It has been scientifically proven that CO2 causes concentration problems at levels much lower than previously thought, namely already below 1,000 ppm.)

Sensitivity to Environmental Stimuli

Tinnitus

It may sound surprising, but a common cause of tinnitus is a lack of oxygen or too high exposure to CO2.

In the past, I often experienced tinnitus after visiting nightclubs, which could last up to four days. Interestingly, this never occurred at open-air events. However, doctors consistently attributed my tinnitus to the loud music.

A few years ago, I suddenly began experiencing tinnitus, even in the absence of loud environmental noises, and it didn't subside until I started paying attention to better air quality. High concentrations of pollutants in the air can trigger tinnitus within seconds, and it may take several days in an environment with good air quality for the tinnitus to diminish.

(The correlation between NO2, CO2 and tinnitus is scientifically proven)

Inflammation

Inflammation in the body has been scientifically proven to occur at around 1000 ppm CO2 in indoor air. This can lead to oxidative stress, poor wound healing, and a weakened immune system.

Exposure to 2000 ppm CO2 for a period of 10 minutes can, in some individuals, lead to the formation of pimples and boils. These skin conditions might be exacerbated by the body's inflammatory response under such environmental stress. It's essential to ensure good ventilation in living and working spaces to maintain CO2 levels well below these thresholds for better overall health and skin condition.

(The connection between CO2 and inflammations, as well as the deterioration of the immune system, is scientifically proven. Studies have shown that this occurs much earlier than previously assumed, namely already below 1,000 ppm)

Reduction in Muscle Strength

Air pollutants can impair the oxygen supply to muscles, leading to a reduction in muscle strength.

Based on our personal observations, this impairment can become noticeable within just a few seconds in environments with high concentrations of pollutants.

This could provide a scientific explanation for the functioning of dowsing rods. A dowser, continuously tensing their muscles while holding a dowsing rod, might experience an immediate, yet unnoticed, change in muscle strength upon entering a room with poor air quality. This change could lead to the dowsing rod reacting. Although dowsers may not be aware of this process and might interpret it differently, this insight offers for the first time a scientific perspective that suggests the feasibility of using dowsing rods to detect poor air quality.

(Reduced muscle strength has been demonstrated in studies even at low concentrations of CO2 and NO2)

Anorexia / Obesity

CO2 can influence lipid metabolism, thus altering how the body processes nutrients.

In some individuals, this can result in the body not storing fat, potentially leading to anorexia in extreme cases. In others, it may lead to increased fat storage. However, in these instances, the body does not use the stored fat as an energy source but compensates for the lack of energy by increasing the desire for food.

For those affected by this disorder, attempts to lose weight often prove unsuccessful and can be distressing. The desired weight loss outcome often does not materialize or cannot be sustained in the long term. A similar situation occurs with anorexia: the body cannot adequately process the ingested food and thus attempts to get rid of it.

Our experience shows that just a few days in an environment with less than 600 ppm CO2 and low exposure to other pollutants can automatically change eating behavior. As quickly as good air quality can contribute positively to health, poor air quality can have the opposite effect. Therefore, anyone wishing to maintain a healthy weight should primarily focus on consistently good air quality. Further positive effects often follow naturally.

(Studies showed a disruption of lipid metabolism already at 1,000 ppm CO2)

Chronic Fatigue / Sleep Disorders

Long-term chronic exposure to air pollutants like CO2 can lead to chronic fatigue.

Until I understood this connection, I used to sleep about 16 hours a day. Now, with CO2 concentrations below 600 ppm, I only sleep 5 to 7 hours and feel much fitter than ever before.

Given that poorly ventilated homes often have very high CO2 concentrations, it's possible that for some people, the COVID-19 lockdown triggered symptoms of chronic fatigue due to increased exposure to air pollutants. Another issue could have arisen from the mandatory use of masks, as they can also increase the concentration of CO2 inhaled.

Sleep disturbances are demonstrably triggered by high CO2 concentrations. Yet, even in sleep laboratories, questions about home living conditions or bedroom ventilation habits are often not asked.

(Studies have shown sleep disturbances and chronic fatigue already at 1,000 ppm CO2)

Bone problems

Elevated CO2 concentrations in the environment can potentially impact bone health.

Research has shown that exposure to increased levels of CO2 can affect various biochemical markers in the body that are relevant to bone metabolism.

For instance, studies focusing on exposure to elevated CO2 concentrations have observed changes in the excretion of bone resorption markers, such as collagen crosslinks.

Personality Changes

While CO2 tends to cause concentration problems and fatigue, NO2 can penetrate directly into the brain and cause significant disturbances there.

These disturbances can be as varied as the people themselves and can have dramatic consequences after years of exposure.

Some of this is detailed in my life story. To give you a preview: It can make the difference between being "normal" and a "psychopath."

If your partner seems like an angel on some days and then you find yourself arguing over trivialities the next moment, consider whether it might be related to the environment or air quality before blaming your partner or yourself. Sometimes, just opening a window can make all the difference.

(Studies have shown that NO2 directly crosses the blood-brain barrier and can trigger aggressive behavior)

Type 2 Diabetes

Specifically regarding Type 2 Diabetes, there are studies attributing more than 10% of the cases to the effects of the air pollutant NO2. However, these studies do not take into account individual exposures but only environmental burdens.

Based on our experience, individual exposures to air pollutants are often significantly higher than assumed in such studies. Therefore, it is plausible to suspect that a significantly higher percentage of cases could be attributable to air pollution than previously thought.

(Studies attributing more than 10% of the cases to the effects of the air pollutant NO2)

Cancer

Air pollutants are known to contribute to the development of various types of cancer, not just lung cancer.

Specifically, CO2, NO2, and particulate matter are known for their toxic properties. These pollutants can cause oxidative stress and impair the oxygen supply to organs, which in turn can promote the development of cancer and weaken the body's immune system.

(Various types of cancer have been linked to air pollution in studies)
