Wel, every single human who breathes Oxygen dies eventually. Just saying.
It’s a decent hypothesis, but you’ll never gather enough data to convince the naysayers.
“The results just aren’t in yet, look at all the people alive”
So to not die, we just need to stop breathing !
Pure oxygen is actually toxic for humans, leading to hyperoxia. People who breath pure oxygen such as scuba divers need specific training.

I always think this when I see those annoying posts about diet coke dissolving screws.
Oxygen will burn your lungs, that’s why we dilute it with nitrogen
Life is a game of burning but trying to do it slowly.
Our lives are a balance between needing oxygen and preventing oxidation damage. We have several enzymes that constantly reduce radicals and chemicals caused by oxidation. So yes oxygen is continuously damaging us. And will eventually win.
100% of people exposed to oxygen die.
Ban the wOkE government chemical Dihydrogen monoxide from our water supply! BAN DHMO, LIBERATE AMERICAN WATER FREEDOM! 🇺🇸🦅👊🇺🇲🔥🦅🇺🇸 USA! USA!
Wait until you read about Dihydrogen Monoxide. Everyone who has ever been exposed to it has died.
There’s a whole website dedicated to raising awareness of its danger : https://www.dhmo.org/
The funny (and scary) thing is how many conspiracy theorists will not get the joke or realize it’s water.
Wait till you hear about this ancient roman curse called gravity.
I mean, oxygen is the most aggressive oxidator, to the point we named the process after it.
F you.

And if you meet flourine out on the wild, you will be F’ed. It will bind itself to you without your consent or caring about things like essential biological processes for life.
70-80+ years exposure to this stuff is lethal
Imagine what it can do to software
It can document it!
Those damn electrons!
There are quite a few sci-fi stories and short stories built on a similar concept. One of my favorites is an alien ship lands on a random farm in the US and (leaving a lot of details out, read the book!) it comes to light that the aliens normally live at insanely hot temperatures like 900F (480C) and consider Earth an “Ice World” (that’s also the name of the book). Anyway, one of the catches in the book is that farmer figures out the alien wants to trade (again skipping a lot of details) but all he has on him that he can give up is a cigarette (the farmer doesn’t know it’s super hot inside the ship). He does the trade and we later find out that most of the galaxy is INSANELY vulnerable to being 100% completely utterly addicted to nicotine. When the alien took in the cigarette it instantly vaporized and sent the nicotine into the air and they breathed it and became instantly addicted worse than any opiod addiction IRL.
You didn’t mention the book name, so how are we to read it?
That’s the exact theme of many stories on r/HFY
Unrelated but the bottom navbar in that screenshot makes me long for the Alien Blue days of Reddit. I also just miss that iOS design (along with the OS X Mavericks design)
Dude, I just had to use an old Mac with OS10.11 on it (I know not that old) to recover a laptop in target disk mode.
It still has the widgets!
I miss the widgets.
I’ve currently been reducing my oxygen intake. My wife keeps telling me it’s impossible and my doc says I’ll supposedly die, but they’re just hating on my progress.
This is a valid athletic technique. Usually achieved by training at altitude.
Doesn’t it only work if you then return to a lower altitude? I wonder how long the benefits last for.
Now that I think about it, I don’t actually know how this even works. Well I know what I’m going to go read about next.
Edit: My findings:
-
At high altitude, cardiac output (the overall rate of blood pumped by the heart) increases, largely due to increased heart rate. This increased heart rate reduces as one acclimatises to high altitude (though I’m unsure of if it returns to baseline. It appears to be complex, and at least somewhat differing person by person. These individual differences may explain why some people experience health problems at high altitude, beyond the initial ill feelings caused from first arriving somewhere that’s high altitude)
-
The stroke volume (volume of blood pumped by each beat of the heart) is lower at high altitudes. This does improve as one acclimatises, but not entirely. This seems to be affected by blood pressure stuff, such as reduced plasma volume at high altitude. It seems to be complex enough that we don’t fully understand how the various regulatory stuff works.
-
Most of the acclimatisation occurs by increasing the number of red blood cells in the blood. The hormone erythropoietin, which usually exists at a low level in non-hypoxic conditions, stimulates the production of new red blood cells. At high altitude, the level of erythropoietin in the blood rises to around 1000 times its baseline level. Increased production of red blood cells happens for a few weeks, by which point, there is enough to make up for lower oxygen levels at high altitude.
-
When returning to low altitude, it appears that the changes back to the baseline happen over a similar timeline.
Tangential fun fact: a red blood cell has a lifetime of around 4 months. A single red blood cell travels around 400 miles before it is old enough to be recycled by the body.
Its also said that smokers are used to having less oxygen intake so if you throw a smoker and a non smoker on a mountain for a night, the smoker is less likely to get altitude sickness. Long term staying at altitude they’ll no longer have the advantage.

I got my oxygen intake down to single digits! My family wasn’t supportive however and got me a new pair of lungs, haters
Big O lackeys are everywhere. They want to keep you alive so they can sell you more O.
On the topic, as oxidation is a pretty prevalent negative side effect of living, our body has multiple mechanisms to deal with it, no? So my question is: where do the “antioxidants” that we can eat come into the picture here? Are they like preventing oxidation from even occurring, or are they like the shields that our cells use to protect themselves from oxidative stress, or what have you?
we have enzymes to prevent oxygen radicals from forming. such as Superoxide dismutase, which is present in nearly every cell in our body, and we have 3 different version. most oxygen dependant organisms have similar enzymes.
another fun fact, our immune system can produce the same superoxide as a defense against bacterial infections, reactive oxygen species including radical oxygen. but bacteria can produce the enzyme to neutralize that too.
i think the dietary source, is somewhat alittle homeopathic/ pseudosciency, because our stomach acid would probably neutralize any beneficial effect before we can absorb it. of course there are some foods that provide nutrional benefit to certain cells(if they a chemical compound). but they dont have like anti-oxidant effect of something like superoxide dismutase. also because of this effect, people with chronic illness as a result of the dysfunction.
Oxidation is the loss of electrons, whereas reduction is the gain of electrons. The mnemonic is OIL RIG: Oxidation Is Loss, Reduction Is Gain.
Oxygen is highly electronegative (second only to fluorine), meaning that it will strongly attract electrons. So, oxygen is good at oxidizing things. It’s good at stealing their electrons. (When the oxygen takes the electron, the oxygen becomes reduced!)
The reason that oxygen is so important in your body for respiration is because of its high electronegativity. It is used as the final electron acceptor in a chain of chemical reactions that are used to convert high energy molecules that you’ve eaten into different high energy molecules that your body can use.
Think of the analogy of a staircase and a ball. The ball is an electron and the stairs are energy states of different molecules along the metabolic pathway. As the ball goes down the stairs, the electron loses energy (which is usually converted to ATP or NADH). At the bottom of the stairs is oxygen, once the electron gets there, it doesn’t have anymore potential energy to lose, unless maybe you have some fluorine around. The final, reduced state of oxygen in this pathway is carbon dioxide. It’s no longer useful for respiration and thankfully can just be exhaled. How convenient!
An oxygen missing an electron (an oxygen radical) is highly reactive. This is not good. It’ll just steal an electron from whatever molecule is nearby. That may be DNA or any other molecule that it’s in your best interest to keep intact. Antioxidants are helpful as electron donors, neutralizing radicals before they do damage.
Ok, I’m going to make a new nutritional supplement: “oops! all electrons!”
antioxidants are our internal sacrificial anodes?
Cell mechanisms cause oxidative stress in the body which can lead to inflammation and faster aging. Antioxidants provide the body with an easy way to neutralise the bi-products.
I actually thought about this a few years ago, is it possible that we age because of oxidation to some degree? Is there a way to prevent that? I thought about it, how blood can rust and just had the connecting thought but I’m not smart enough to know if there’s any actual correlation.
Edit: Got some really cool responses out of this to think about, thank you everyone!
Pretty sure oxidation plays a major role in aging, but can’t tell you the exact mechanism, I have no idea about it.
But about the blood rust idea, I don’t think that can work, cause we don’t have just iron particles that can directly interact with oxygen just floating around in our blood, we have a complex (I.e. hemoglobin) that contains significant amounts of iron, which somehow makes it really good for binding to and carrying oxygen.
Deviating a bit, carbon monoxide poisoning is really akin to suffcation iirc, cause it binds and occupies the hemoglobin, effectively reducing the amount of oxygen that can be carried by your blood.
However, do fact check me, I might be wrong about something…
Edit: BTW, it seems that “oxidation” might not be the right term to use here, so do understand that I am referring to free radicals here.
You’re pretty much right about everything. Oxygen (especially as free radicals) is damaging to pretty much all your tissues, so your body moves it around in little bodyguard proteins (hemoglobin). These each contain 4 small iron molecules as part of the much bigger structure and doesn’t rust or function like iron in any way. The iron is mostly used for electrons (and also damages your body if it’s not inside the hemoglobin and causes more aging)
Carbon monoxide has a higher affinity for hemoglobin than oxygen, so it sticks to your blood cells and makes them useless for hours. Super dangerous.
Point being “oxidative stress” is bad for you and a major cause of aging that your body tries to fight. If your body doesn’t fix this well, you age faster. If it repairs damage too well, you’re more prone to cancer. Just wear and tear of using your body.
So to the original question of can this process be stopped… Absolutely! Hold your breath - the oxygen will stop coursing through your body and you will stop aging. Just ten minutes is enough to end aging indefinitely! Then you have to worry about other problems like body decomposition, but the oxidative stress will be cured!
Carbon monoxide, not dioxide.

I’m no expert but I’m fairly sure that is basically true in a way. As per zr0’s top-level comment. Forms of life that can make do with less cellular respiration, for example by using external sources to regulate temperature (cold- blooded), don’t need to invite as much oxygen into their cells, and so they get less weird damage over time. Mammals in general have not adopted this strategy.
