What happens if you breathe pure oxygen for too long?

Contrary to popular myth, hyperventilating air at ordinary pressures never causes oxygen toxicity (the dizziness is due to CO2 levels dropping too low), but breathing oxygen at pressures of 0.5 bar or more (roughly two and a half times normal) for more than 16 hours can lead to irreversible lung damage and, eventually.

Why is it bad to inhale pure oxygen?

Breathing pure oxygen sets off a series of runaway chemical reactions. That’s when some of that oxygen turns into its dangerous, unstable cousin called a “radical”. Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally.

Is it dangerous to breathe pure oxygen?

So, the short answer is, pure oxygen is generally bad, and sometimes toxic. Your lungs are basically a long series of tubes that branch out from your nose and mouth (from trachea to bronchi to bronchioles) and end in little thin-walled air sacs called alveoli. Think of soap bubbles on the end of a straw, and you’ll understand alveoli.
