How much oxygen is there in the air? Everything you need to know

When we think about indoor climate and air quality, we often overlook the essential aspect of the oxygen content in the air. Oxygen is essential for our well-being, but how much oxygen is actually in the air we breathe every day?

The percentage of oxygen in the atmosphere

The composition of the atmosphere consists of approx. 21% oxygen, 78% nitrogen, 0.038% carbon dioxide and 0.93% argon. These oxygen percentages are essential for human survival and health, as oxygen is used for cellular respiration and energy production.

Why is oxygen important?

Oxygen is needed for cellular respiration, a process in which the body's cells use oxygen to produce energy from glucose. Without sufficient oxygen, we can experience symptoms such as fatigue, dizziness, and in extreme cases, unconsciousness.

The risk of too much or too little oxygen

While having sufficient oxygen is important, too much oxygen can also be harmful. Over-oxygenation can lead to oxygen poisoning, which can damage the lungs and central nervous system. Read more about the risks of oxygen at Crowcon .

Indoor climate and oxygen

In modern buildings, the oxygen content can be affected by many factors, including ventilation, number of people in the room, and the presence of pollutants. Effective ventilation is key to ensuring a constant and healthy level of oxygen indoors.

According to our blog on CO2, plants or venting, venting is one of the most effective ways to improve air quality. Plants can also help, but aeration is essential to remove excess CO2 and supply fresh oxygen.

Measure and optimize your oxygen content

To ensure optimal air quality, it can be useful to measure the oxygen level regularly. IoT solutions such as those we offer at ÅBN can help monitor and optimize air quality in real time.
