Most people can only hold their breath for 1-2 minutes. Some record divers can hold their breath for more than 24 minutes. The length of time a person can comfortably and safely hold their breath depends on the body and genetics. Inexperienced people should not try to hold their breath for more than two minutes. Repeatedly holding your breath for long periods of time can suddenly reduce the amount of oxygen in your blood, leading to health problems. With us you will be able to control the level of oxygen in your blood, which will help you avoid these problems.

About 2.4 billion years ago, Earth experienced an oxygen catastrophe. The first cyanobacteria (blue-green algae) began releasing oxygen en masse through photosynthesis.
