Swimming is always less than the height of water, why can drown people?

Answer:

According to the study, drowning can be basically divided into two types: one is drowning drowning occurs when the mind is lucid, these people in the event of drowning usually there will be a certain degree of brief struggle; the other is drowning occurs when the drowning man has lost consciousness, this situation often occurs in the process of serious diving the head or cervical trauma, or paroxysmal diseases, such as heart attack, stroke or seizure, and is called a shallow water syncope situation.
In the second case, loss of consciousness occurs before drowning, and drowning occurs quietly. If the temporary loss of consciousness occurs on the land, the result is what we call "fainting". Usually, after treatment or without treatment, we wake up to ourselves. However, loss of consciousness occurs in underwater activity, and death is almost inevitable if it is not discovered and saved in time. In this case, regardless of whether the body is drowned is tall, strong physique, and whether it can swim.Traumatic and episodic diseases cause loss of consciousness, which is not difficult to understand. What is the condition of shallow water syncope?
Shallow Water Blackout (SWB) refers to the loss of consciousness in the shallow water of divers who are less than 5 meters deep in the brain.SWB has generally been regarded as an ordinary drowning because of lack of awareness, so there is no data on the incidence of SWB. However, SWB is now considered to be the number one drowning reason for experienced swimmers, especially young adults.According to the WHO (WHO) was first released in 2014 global report 37200 people died from drowning, drowning passive worldwide in 2012, including a good swimmer, including swimming athletes and professional free divers.Our country folk also said "drowned are swimming", although this is not entirely correct, under normal circumstances, people who can swim drowned opportunity than not. However, it also shows that people who observe "swimming" will be drowned, but the reason is puzzling. Therefore, it is not surprising that people take it for granted.If you know something about SWB, you won't be surprised at the phenomenon of "drowning and swimming.".
