Higher-than-normal oxygen levels aren't as harmful to life, but there is an increased change of fire or explosion risk. With extremely high concentrations of oxygen in the air, humans can experience harmful side effects. Very high levels of oxygen cause oxidizing free radicals to form. These free radicals attack the tissues and cells of the body and cause muscle twitching. The effects from short exposure can most likely be reversed, but lengthy exposure can cause death. The right amount of oxygen starts at sea level.
When altitude is increased, such as driving or climbing up a mountain, there is less atmospheric pressure. Lower pressure allows air to expand more than it does at sea level. While the ratio of the oxygen and nitrogen in the air remains the same, less molecules are available within the same space. Each breath you take at a higher altitude contains less oxygen molecules than breathing at a lower altitude. Some places are more humid and some are more polluted — the higher the concentration of other gasses in the air, the lower the concentration of oxygen.
Furthermore, oxygen levels also change over longer periods of time. We knew for a very long time that oxygen concentration in our planet does not remain constant — it is always changing. They revealed that eight major peaks in the cycles of atmosphere oxygen occurred at , , , , , , and million years ago. The problem with oxygen is that it is quite reactive, oxidizing other elements, including those in your body. In fact, you exhale pretty much entire nitrogen that you inhale.
It is just a bumper gas, protecting your body from harmful effects of oxygen. This also means that when people move to Mars, they will have to produce an air-like mixture. Argon, unlike nitrogen, is not much good for anything else, which means that will be a great substitute. It will make your voice deeper, though. Additional comments optional.

Oxygen radicals harm the fats, protein and DNA in your body. But breathing pure oxygen can sometimes be necessary. Astronauts and deep-sea scuba divers sometimes breathe pure oxygen because they work in very dangerous places.
Sick people, including premature babies in hospital or people in hospital with the coronavirus , might also need some extra help breathing. Michael Roizen, MD. Research now indicates that indoor air quality could be five times more aging for us than outdoo Why can mold be a dangerous air pollutant? Molds produce mycotoxins, which weaken or kill the things they live on or compete with. Short-term e Does altitude change the percentage of oxygen in the air?
