"Dry drowning": water in the lungs is a time bomb for the alveoli
If water gets into the lungs, no matter if much or little, the alveoli can stick together. The delicate membranes cannot withstand the force of the water. The lack of oxygen intensifies this effect and further restricts the metabolism. However, this does not have to be immediately noticeable at the scene of the accident; it can also occur hours later. Just like an infection from the inhaled water, which can then lead to pneumonia. This phenomenon is known under the term "secondary drowning", which is, however, controversial among medical professionals and which the WHO does not recognize either. It is therefore important that everyone who has been rescued is then observed in the hospital for at least 24 hours. Even if he has spat out the inhaled water and makes an overall impression of being stable.
Whether the drowning person inhales fresh or salt water plays only a minor role. It is true that salt water contains ions that encourage the surrounding cells to pump even more water into the lungs. But compared to the effect of the lack of oxygen itself, this is not decisive for the chances of survival and recovery of the rescued person.
Land life humans: How long can we stand it underwater?
That depends on a number of factors: if you are healthy, well trained and calm, you can stay under water longer without harm than someone in poor physical condition who lashes out in the water. Absolute apnea diving professionals can do it for ten minutes, then the carbon dioxide concentration in their blood becomes too high. The urge to breathe increases. The body signals: please come up - or just: breathe in!
Avoid swimming accidents - but how?
Last summer at least 504 people drowned in Germany. A full 86 percent of them in inland waters. Including non-swimmers who have had accidents, swimmers who overestimate their strength. A heart attack or stroke in the middle of the lake, cockiness or alcohol and drugs can also cause a bathing accident. Getting into deep water carefully and thinking about your condition beforehand can help to avoid unhappiness.
The little ones drove themselves in shallow water
Anyone who cannot swim yet is generally at risk in and around deep waters. The usual swimming aids are not a guarantee of survival and in no way replace personal non-stop supervision by adult swimmers. But there is also a high risk in shallow water: due to their physique, children often cannot save themselves even in shallow water. They frolic, fall down and can no longer get their heads above the surface of the water. It is just too big and heavy compared to the body. The smaller the child, the stronger the effect.
A Forsa survey showed that 59 percent of ten-year-olds in Germany cannot swim safely. A safe swimmer in this context is someone who has received the youth swimming badge in bronze. Among other things, you have to cover a distance of 200 m in less than 15 minutes. Even if the number of deaths from swimming accidents has decreased significantly since 1951, the German Lifesaving Society (DLRG) is critical of the result. The closure of many public baths for cost reasons would have resulted in around 25 percent of primary schools no longer having access to a swimming pool to take swimming lessons. And that's where most of the children eventually learned to swim safely.
