There's advertising for water ozonizers everywhere now, and they're saying it's basically a cure-all. My friend bought herself an ozone generator for 15 thousand rubles and has been drinking ozonized water for a month already. But I don't get it - is there actually any scientific basis to this or is it just marketing?
Ozone does actually kill bacteria and viruses - that's a fact, but it only exists in water for a few minutes before breaking down. So by the time you drink ozonated water, there's basically no ozone left in it. All that remains is water with oxygen, just like if you opened a bottle and let it sit for a while. But the supposed miracle health benefits from drinking ozonated water aren't scientifically proven. If someone feels better - it's most likely a placebo effect or just taking better care of yourself (you spend more time thinking about what to drink, so you end up drinking more water overall).
Ozone generators make sense for disinfecting rooms or aquarium water, where ozone works on the spot before it breaks down. For drinking - it's pretty much wasted money. If your friend feels better - well, maybe she just needed that kind of motivation to keep track of her water intake, and that's good. But it's unlikely to be because of the ozone in the water itself.
Ozone in water is indeed unstable - that's true - but here's the thing: it kills microbes in a matter of minutes while it's breaking down, so ozonation makes sense as a disinfection method, not as a way to saturate your body with some magic gas. In practice, ozonated water is no different from regular boiled or filtered water - the microbes are already dead, there's no ozone left, just clean water. If your friend drinks ozonated water for a month and feels better, that's most likely a placebo effect or she's just drinking more water in general. For 15 thousand you could buy a good filter that would work way more effectively.
