2. Oxygen deficiency > Consequences in the long term

1. Cardiovascular diseases

A lack of oxygen means that the cardiovascular system is permanently on the threshold between aerobic and anaerobic metabolism.

However, this does not strengthen the heart, nor does it improve the training condition, resulting in a state of exhaustion.

In combination with lack of exercise this condition leads to heart failure and high blood pressure in the long term.

A lack of oxygen also has a negative effect on the condition of the blood vessels. The pH value in the human organism is reduced and the tension in the area of the blood vessel walls is reduced.

Consequently, the development of arteriosclerosis and peripheral arterial occlusive diseases is also favored.

2. Orthopaedic diseases

A lack of oxygen means that muscle cells have to work too much in anaerobic metabolism. This leads to higher lactate accumulation, fascia adhesions and muscle shortening.

The supply of bone and cartilage cells is also impaired.

3. Mental illnesses

Oxygen deficiency impairs the nervous system of the human organism and leads to states of exhaustion.

This also has a negative impact on mental illness.

4. Cancers

Due to a lack of oxygen, more and more cells in the human organism fall from aerobic to anaerobic metabolism for energy production.

In combination with other individual cancer factors, cells increasingly go into inactive mode and develop into cancer cells.

5. Respiratory diseases

A lack of oxygen worsens lung function and impairs the cleaning mechanisms of the lungs.

This increases the potential for the development of respiratory diseases.

6. States of exhaustion

A sufficient supply of oxygen is essential for every cell in the human organism to work in aerobic metabolism at rest or under moderate stress.

If this is not guaranteed, only a few other factors are needed for exhaustion to develop.

7. Performance greatly reduced

It usually takes a little more than a lack of oxygen to cause massive exhaustion.

However, a reduced oxygen supply can already lead to greatly reduced performance.

8. Frequent occurrence of infections

The likelihood of infections occurring is significantly increased by a lack of oxygen.

It creates an environment in the human organism in which pathogenic bacteria feel comfortable and health-promoting bacteria do not.

The lack of oxygen is particularly worrying if you already have an infection.

3. Causes of oxygen deficiency

  • Too much time indoors, too little time outdoors
  • Incorrect and inadequate ventilation
  • Living in the city
  • Deforestation without reforestation
  • Increasing sealing of surfaces with concrete and asphalt
  • Environmental toxins inhibit plant growth
  • Increasing water shortages in large parts of the world
  • Increased oxygen consumption due to road traffic and power plants
  • Lower oxygen production by plants in winter

4. Prevent oxygen deficiency

4.1 Spend at least one hour a day in the fresh air, ideally in combination with aerobic exercise

4.2. Do not spend hours in closed rooms with large numbers of people. Take a short 10-minute walk with a conversation partner during a party or spend your lunch break at work in the open air!

4.3. Ventilate instead of opening the fanlight! 1-2 minutes of airing brings a much higher air exchange than opening the skylight for an hour. All energy consultants also recommend this method for cost reasons.

4.4. Ventilate 2-3 times a day

4.5. Force yourself to go outside, especially in winter, due to the lower oxygen production. Cold or bad weather is no excuse!

4.6. Try to do lots of outdoor sports! To go running, for example, you don’t have to go to the gym on the treadmill, you can just as easily do it outside.

4.7. Living in rural areas offers more oxygen and cleaner air. I advise all city dwellers to go for a run/walk in the forest at least once a week for an hour.

5. Oxygen - Conclusion

There is a historical imbalance on Earth between oxygen (plants) and CO2 producers (animals and humans). As a result, a massive imbalance between oxygen and carbon dioxide has developed in the atmosphere.

CO2 is not, as is often claimed, the dangerous greenhouse gas, but together with oxygen regulates the imbalance of oxygen and CO2 producers created by humans.

Higher levels of CO2 and increased solar radiation lead to a significant increase in plant mass, especially in the world’s oceans.

For humans, more CO2 and less oxygen means significantly more difficult living conditions and an increase in civilization diseases. For this reason, the above rules for preventing oxygen deficiency should always be followed.
