One of the important lessons I learnt from a lifeguard is that movies depict a very inaccurate representation of drowning. The movies would have you believe that drowning is a violent and noisy event when in reality it is an inconspicuous and silent event. The victim cannot shout or call for help when they are struggling to keep their nose above the water level.
Another important lesson I learnt that sometimes when someone is rescued from drowning, they are at the risk of secondary drowning which can occur during sleep after the accident. Especially, if a child looks very weak and tired after a drowning accident, it is important to keep the child under medical care for the next 24 hours. Never take the risk of the taking the child back home in such a case.

- mikequinlan 7y agoThe water (and chemicals) in the lungs irritate and damage the lungs, which causes inflammation, which causes fluids to build up in the lungs, which eventually causes suffocation.
- cVwEq 7y ago"Secondary drowning" is another term people use to describe another drowning complication. It happens if water gets into the lungs. There, it can irritate the lungs’ lining and fluid can build up, causing a condition called pulmonary edema. You’d likely notice your child having trouble breathing right away, and it might get worse over the next 24 hours. Both events are very rare. They make up only 1%-2% of all drownings, says pediatrician James Orlowski, MD, of Florida Hospital Tampa.

- young_unixer 7y ago1%-2% doesn't seem "very rare" to me.
- dmos62 7y agoWhat kind of intuition do you have about 1%-2%? I've a crappy grasp of probability. I'd say 1-2% is like being quite certain that you'll experience this or that within 50-100 tries/repetitions. That sounds rare to me. In case of life or death it's not a risk I'd tolerate, but I'd call it rare.
- saagarjha 7y agoEven with a 99% probability, there’s about one chance in three that you wouldn’t experience it if you tried a hundred times.
- dmos62 7y agoHow does that work?
- saagarjha 7y agoThe chance you don't experience it after hundred times is 0.99^100≈0.37.
- notafraudster 7y agoLet's say you roll a dice with 100 sides. If you roll a 1, you die. If you roll anything else, you live. We want to know the probability you will die if you roll the dice 100 times. One way we could do this is look at the probability you'll roll it on the first roll... then the probability you won't roll it on the first roll but you will on the second roll... and so on. But that's a lot of math. The probability of an event (death) and its complement (not death) totals 1.0. So one way we can get the probability of death is 1.0 - the probability of life. Okay, so the only way you'll live if is if survive all 100 rolls. Each dice roll is independent (surviving the first dice roll doesn't affect the second dice roll which doesn't affect the third). So each individual dice roll has probability 0.99 of survival. For joint probability, we can multiply these together. The probability of getting heads on a coin twice is 0.5 * 0.5 = 0.25. So in our situation here, p(survival) = 0.99, and 100 times means 0.99^100, to get the probability of survival. 0.99^100 = 0.36. 36% chance of survival. The probability of death is thus 1 - 0.36 = 0.64. 64% chance of death.
- rsync 7y ago"Is there still water in their lungs? Why doesn't it get coughed out once they are out of the water?" No, it is not as simple as "leftover water from the drowning". Rather, due to the presence of the water in the lungs, which has been presumably expelled entirely, the interior of the lungs becomes irritated and inflamed. This inflammation process produces it's own fluid which will slowly fill the lungs and "drown" you - especially while you are prone, while sleeping, wherein the fluid pools along the entire length of the lung, rather than just filling up the bottom of the lung. It's a misleading term ...
- JdeBP 7y agoAn important lesson to learn in general is that television and movies depict very inaccurate representations of everything.
- TeMPOraL 7y agoIncluding sounds, which are almost universally added to the footage in a separate processing stage, and have no relation to what has actually happened on the stage itself.
- grawprog 7y agoHence why every bird of prey ever shown in any movie ever has the call of a red tailed hawk.
- b0rsuk 7y agoDo you know a single movie which accurately shows drowning?
- Darkstryder 7y agoSecondary drowning, while not shown on-screen, is an important plot point of the series The Affair.
- Ygg2 7y agoThey had those in Baywatch, although they claimed to be caused by saltwater. But overall their message was the same, post drowning, go to hospital.
- BiteCode_dev 7y agoMost depictions of things in movies are like that. Films must show you something interesting, and watching somebody do trial and error painfully on a bash script for 6 hours is not as fun as a fast pace keyboard murder while screaming "i just passed 3 firewalls" with beautiful animations rendering on the screen. If there is a camera, what you see is a lie. The difference between a national geographic documentary and cinema is just how big the lie is. It's a bit insiduous actually, because some parts of the lie are subtil: rythm, speed, dialogs, personalities, agenda, resources... But they look real enough to make our natural social mechanisms trigger, and the lie then creeps into real life. Like people now expect the police, the justice system, school or the hospital to behave in a certain way, and the reality is way less glamourous. The chances we actually find, or even search for somebody that killed you (if it's not very obvious) are very low, not to mention a simple theft or ass kicking. Most things are mondain and boring looking. That's why we are so fond of art. And drowning is like most things.
- fho 7y agoEven national geographic documentaries are probably "lies" ... I just had the chance to get some basic insights in to evolutionary biology ... and boy is bloody mauling and devouring of prey just the tip of the iceberg. Intraspecies rape and infanticide is pretty common out there. (Look up the penis of drakes (male ducks) and why it looks the way it does at some point) Siblings competing for food with only a small percentage surviving. The female tit (the bird ... not what you think) basically cheats so much that there is a possibility that none of the offspring is actually of the male that feeds them ... The list goes on and on and on ...
- notRobot 7y ago> The female tit (the bird ... not what you think) basically cheats so much that there is a possibility that none of the offspring is actually of the male that feeds them ... Pretty sure "cheating" and infidelity are largely human concepts. That's normal and natural behaviour for many species.

- econcon 7y agoI never learned to swim. At age 14 I felt like someone pushed me into the river at noon time, sun was very bright and there was no one there but me catching fishes alone, I fell right into the river. I didn't drown I figured out how to swim out of instinct - I wonder how common it is. This is one of the least things shown in movies that some people can end up swimming on their own without having previously learnt it.

The movies would have you believe that drowning is a violent and noisy event when in reality it is an inconspicuous and silent event. The victim cannot shout or call for help when they are struggling to keep their nose above the water level. My daughter, when she was about 2, fell over in about 2 feet of water in a lake and it was completely and utterly silent. One moment she was there and the next she was under and reaching up at me, bubbles coming out of her mouth. If I had been even remotely distracted I never would have known that she had gone under.
- jakemal 7y agoWhen I was a kid I was swimming in a children's pool in our backyard with my two younger brothers. One of my brothers was afraid to go under water. At one point, I turned around and noticed that he was underwater. It looked like he was making swimming motions as people normally do. I was surprised that he decided to do it, given his fear, and just watched him for maybe ten seconds. After some time passed I got concerned and pulled him up. Sure enough, he was drowning and I was just sitting there watching him. I learned that day how non-obvious drowning looks. I still feel bad about it to this day, even though he ended up being alright.
- ensiferum 7y agoYeah this can happen because the bronchi in the lungs is covered with this "teflon" like non-stick coating that prevents the lungs sticking together when breathing out. When a person inhales water in a near drowning this coating might get washed away resulting in the bronchi to get stuck. This will reduce the breathing capacity of the organ could result in hypoxia. Therefore after near drowning supervision in a hospital is a good idea.
- MS90 7y agoThere was a video my fireman friend showed me a while back of two men drowning near a drainage pipe. There was a chunk of floating hardwood or something that they wanted for some reason, but neither could swim (I know, brilliant). The only violent and noisy parts of the incident was then frantically trying to swim back to the banks for about a minute. After that, they seem to lose all energy, go still, and sink shockingly fast, like rocks.
