There was a suggestion from the reader to consider the shower as hazardous to the lungs. There was no subsequent explanation, so I will try to justify the harm and benefit myself.
Here, honestly, without preparation, I will dump everything that is in my soul about the shower.
Let's start with water and hot steam. In the vast majority of cases, the steam makes it easier to breathe and everything clears up. The mothers, whose child had croup pain, know well what it is like to sit in the bathroom with the child in an armful at midnight and breathe in the steam from the shower. There is no doubt about the benefits.
For any cold at any age, it is useful to greatly increase the humidity of the house for a while. A hot shower behind an open bathroom door instantly raises the humidity in adjacent rooms. This is the simplest way to humidify the air.
It is harmful to humidify the air for a long time. If the humidity in the room is above 50% for more than a few days, mold will start to grow in the corners. And already from this mold you can cough up and get sick.
Some asthmatics swear that moist air makes them worse. But, in my opinion, these are only those who react too strongly to smells. Many people feel bleach in water, and this unbalances them.
Now about the water. In the water, there can really be an infection, from which it is easy to get pneumonia. Most often they talk about Legionella. This filth always lives in the water, but there is usually little of it.
Legionella needs water with a temperature of 20 to 50 degrees to grow. If it is below 20, then it grows poorly, and if it is above 50, then it dies.
That is why the water supply of the house must be designed and installed by a professional. There should be no unnecessary zigzags or unnecessary containers along the pipes. This is important so that cold water does not have time to warm up, and hot water does not have time to cool down.
There was a bike ten years ago (from British scientists) that they settled in the shower head non-tuberculous mycobacteria, which will build a biofilm there and then, together with water droplets, will fly out of the shower. But scientists address this horror story to people with impaired immunity. For ordinary average people, such an infection does not harm.
Well, something like this... Did you talk about it, or was there something else terrible?
