It hisses and smells bad. My heartbeat speeds up two gears. With a plastic mask over my mouth and nose, which gives me an emergency-room-ready look, I try to breathe in and out in a relaxed and regular manner. But no sign of relaxation. What on earth am I doing here? According to the website, the special oxygen treatment with “O_PUR” that I was persuaded to take should make me moreTolfioow, increase my performance and concentration and even slow down cell aging. Who does not want that?
I could definitely use a little boost of energy at this gloomy time of year. So I bravely keep breathing – until a coughing attack ends the experiment for the time being. Sign of a cold or reaction to the highly concentrated oxygen? And shouldn’t it be odorless? Like most living things, humans need oxygen to get nutrientsto burn, which provide energy to the body. The content of this gas in the ambient air is around 21 percent. The brain is particularly sensitive to a deficiency. But: If the concentration is too high, it becomes poisonous. That’s why my bottle of 99.5 percent oxygen comes with instructions for use. It should not be used in certain lung diseases, and only with caution in the case of severe obesity, fever and some other risk factors. Otherwise, hardly any side effects are to be expected. But the package insert makes it clear: What I’m holding in my hands is a medicine! Cardiovascular diseases, states of shock and respiratory disorders are mentioned as indications. I’d be at the doctor’s for a long time!
A feel-good product – and it’s advertised as such on the website – looks different to me. But maybe I’ll change my mind after the next oxygen ration. I prescribe five breaths – the beginner’s dose. That should be enough. After all, I don’t face extreme physical challenges. The same thing again after two hours. Now it works without a cough. And I’ve almost gotten used to the strange smell that apparently comes from the breathing mask. A few days later, everything is routine: open the mask, open the valve, breathe. Only the effect is long in coming. Apparently my body follows the research opinion that oxygen cannot be stored in the blood. Or maybe I feel a little more awake after the oxygen shower? Does theSkin a touch fresher? Could I possibly have fought off an infection unnoticed because my immune system is now working more actively? Questions that will forever remain unanswered.
Conclusion: The oxygen content outside the door seems to be sufficient for my body. After almost three weeks, I give up trying. Unharmed, but just as fit (or unfit) as before.
Further information: The 2 liter can of “O_PUR” with a mouthpiece costs 9.95 euros, the 66 liter bottle with a breathing mask costs 64.95 euros.
