It can start to act on your lungs.

It can start to kill the cells of your lungs.

It definitely starts to act on your nervous system.

So once you get beyond a certain pressure and concentration of oxygen,

Your nervous system can no longer defend itself against this essentially onslaught of reactivity.

And you begin to have these really intense symptoms that if you don't remove the oxygen levels will eventually kill you.

It starts with minor muscle twitches.

So people might have small twitches in their fingers or in their arms.

One of the common ones is the upper lip.

You kind of get a little Elvis thing going on.

People start to have visual disturbances.

The eyes use a ton of oxygen.

And so they're one of the more sensitive measurements that we can have to when our breathing gas levels are going awry.

So people start to hallucinate bright flashes or have twitches of their eye to the left and right.

Eventually, it's going to escalate to seizures.

And then from there, if the oxygen levels are not removed, then you'll have death.

Antioxidants are chemicals that react with oxygen and sort of neutralize it.

So when we eat them in food, the theory is that the antioxidants we're consuming will react with the oxygen that's sort of extra in our bloodstream and neutralize it from having some of the more negative effects that can accumulate over time, like aging.

Oxygen is thought to be the reason that we age.

The problem is dosage.
