Why Pure Oxygen Will Kill You, But The Oxygen In The Air Won’t

We’re dead without oxygen, but we’d also be dead with too much oxygen. Breathing in 100% oxygen will kill in you a few days, with symptoms showing in about 24 hours. Oxygen (along with food) is one of the key ingredients for your mitochondria to produce energy via cellular respiration. But, one of the by-products of cellular respiration is reactive oxygen species (ROS). These ROS react with the molecules that form the cell, eventually disrupting the cell’s functioning and killing that cell. The first organ affected by a 100% oxygen intake is the lungs, followed by the nervous system (which is why you’ll feel dizzy and nauseous after breathing in pure oxygen for too long).

Furthermore, understanding the intricate interplay between oxygen and nitrogen within our respiratory system sheds light on the delicate equilibrium required for optimal lung function. While oxygen is crucial for sustaining life, nitrogen plays a pivotal role in maintaining lung inflation and regulating air pressure within the respiratory system. This dynamic balance ensures the efficient exchange of gases necessary for cellular function and overall physiological well-being. Consequently, disruptions to this equilibrium, such as prolonged exposure to pure oxygen, can have profound repercussions on respiratory health and systemic function. By delving deeper into the complexities of oxygenation and its physiological implications, we gain valuable insights into the fundamental principles governing human biology and health.
