Hidden dangers in bodies of water are something a lot of people don’t think about until it’s too late. Things like strong currents, sudden drop-offs, or even hidden debris can be really risky, especially if you're swimming or boating. Sometimes the water looks calm on the surface but hides serious dangers underneath. Knowing about these things can help you stay safe and avoid scary situations. It also helps you feel more confident when you're out enjoying lakes, rivers, or the ocean. Being prepared can literally save lives. Credit:

FunTranscript
00:00Dangers in the ocean and seas are obvious, but few people realize how terrifying ordinary
00:05ponds, lakes, or rivers can be.
00:08Amoeba living in there can eat your brains, underwater quicksand can trap you.
00:13It doesn't even have to be a body of water.
00:16Even your average bottle of drinking water can ruin your health.
00:20All because of these smelly, blooming algae.
00:24They can be blue-green, red, or brown.
00:27Touch them, and it can be your last day.
00:30Many algae species are toxic to humans and animals.
00:35These green buddies are cyanobacteria, and they can form harmful algae blooms.
00:41This bacteria can perform photosynthesis, and some of its species are capable of producing
00:46dangerous cyanotoxins.
00:49People can accidentally ingest these substances while swimming, inhale their vapors, or eat
00:54fish caught in contaminated waters.
00:58Algae toxins are so widespread that even a water you drink every day can have them.
01:04Although bottled water from a supermarket is much safer.
01:08According to estimates, 30 to 48 million Americans receive drinking water from lakes and reservoirs
01:14that may periodically be polluted with cyanobacteria.
01:19In such cases, the algae can cause serious problems to health, depending on the class
01:24of cyanotoxins.
01:26It can cause skin irritation, liver damage, respiratory problems, and more.
01:31Also, take care of your pets.
01:34Dogs, for example, are very sensitive to the effects of blooming algae.
01:39Almost any water source contains phosphorus, nitrogen, and other substances necessary for
01:45the growth of plants, algae, and microorganisms.
01:49This is completely natural and essential for maintaining life in aquatic ecosystems.
01:54But when there's too much of these substances, they pollute the water and promote the growth
01:59of bad algae and bacteria.
02:02This often happens near cities and rural areas when streams of polluted liquids enter open
02:07bodies of water.
02:09Worm water temperatures encourage the growth of cyanobacteria.
02:13They begin to multiply and absorb more sunlight, making the water even warmer and accelerating
02:19algal growth.
02:21It doesn't mean that it's only algae you should steer clear of.
02:24Water currents pose a serious threat to people too.
02:28And yet again, you can encounter this phenomenon not only in seas and oceans, but also in large
02:33lakes.
02:34For example, it can easily happen in the Great Lakes.
02:39The currents in these lakes form in various natural conditions.
02:42A combination of strong winds, uneven bottoms, beach slopes, waves, and other factors create
02:49dangerous water currents that may be invisible on the surface.
02:53But if you get caught in one, escaping won't be easy.
02:57Some currents can exceed a speed of 5 miles per hour.
03:01That's faster than the speed of an Olympic swimmer.
03:04There are different types of dangerous currents, but let's look at rip currents.
03:09These occur when water gets trapped in a small pocket between a shallow and a beach.
03:15The water accumulates there and has nowhere to go.
03:18More and more water gets into the gap.
03:21Pressure builds up and at some point, the water breaks through a narrow path, flowing out
03:27in a powerful stream.
03:29If you get caught in this stream, it will carry you out into the lake.
03:33To escape, you need to swim sideways.
03:38There are also dangerous currents that run along the shore.
03:41You swim forward a bit and the current starts carrying you sideways.
03:45In this case, you need to swim diagonally towards the shore while moving with the current.
03:52But one of the most dangerous, if not the most dangerous, things in water is underwater quicksand.
03:59If you get stuck, you're in big trouble.
04:02Because the more you struggle, the more the quicksand restricts your movements.
04:06When the water from a natural source, such as an artesian spring, rises and disrupts the
04:12riverbed, it creates a loose and dense mixture at the bottom that becomes a real trap.
04:19This mixture is too loose to support your weight, but too dense to let you escape.
04:24This danger can also lurk in stagnant waters, where an upwelling from underground springs
04:30occurs.
04:32Besides underwater locations, quicksand is most commonly found near coastlines, in swamps
04:38and close to riverbanks.
04:41To understand how to escape from quicksand, let's find out how it works.
04:47Quicksand is a mix of water and dense material, sand, silt or clay.
04:52This combination creates a surface that looks solid but collapses under weight or vibration.
04:58The solid part of quicksand makes up most of its mass, but the water creates space between
05:04the dense particles.
05:06When this viscous substance encounters external stress, it changes its viscosity and acts like
05:12a gel.
05:14When you step into it, the density of this gel decreases and you start sinking.
05:19The sand around your feet collapses and tightens.
05:23The more you move, the longer the mixture remains liquid, while the sand particles compress
05:28around you more tightly.
05:32In movies, we often see quicksand completely swallowing a person.
05:36But in reality, it works differently.
05:39You sink into quicksand up to your waist at most, but you can't get out.
05:44If you're stuck in quicksand near a riverbank, there's a danger that the tide will rise and
05:48the water will flood the area.
05:51You also risk losing body heat or experiencing breathing difficulties.
05:56There are many problems, but only two solutions.
05:59The first is to call for help.
06:01But if no one's around, you must try to escape the sand with very slow, smooth movements.
06:07The more you move, the lower your chances of success.
06:11The first thing you should do is calm down.
06:14The more you panic, the more unnecessary movements you make.
06:18Then try to lean back or forward and slowly move your legs as if attempting to swim.
06:24The less weight and pressure you exert on the sand, the freer your movements will be.
06:30This means you need to shift your weight from one spot and distribute it evenly across the
06:35surface around you.
06:37No sudden movements.
06:38If you reach solid ground, sit on it and then slowly pull your legs out of the quicksand.
06:44If you're far from land, slowly swim toward it and call for help.
06:51And now, the scariest danger some bodies of water hide.
06:55In some of them, there are amoebas that can eat your brain.
07:00They are literally called brain-eating amoebas.
07:04Scientists first discovered these amoebas in the 1960s in Australia after people were hospitalized
07:10with an unusual form of meningitis.
07:14But currently, the largest number of infections are recorded in the United States.
07:18However, only American scientists track cases of this infection.
07:23It's possible that, in other countries, where such records aren't kept, people suffer from
07:28these amoebas much more often.
07:31The chances of surviving an encounter with them are about 3-5%.
07:37Brain-eating amoebas live in warm fresh water and soil.
07:41Salt water or water disinfected with chlorine is unsuitable for these creatures.
07:47Unlike toxic algae, brain-eating amoebas can't harm you if you swallow them.
07:53They infect the human brain exclusively through the nasal passages.
07:57When water enters the nose, the amoeba penetrates the nasal tissue, moving to the brain, and attacks
08:03the central nervous system.
08:05The first symptoms infected people feel are headaches, fever, neck stiffness, and nausea.
08:12The infection can develop within several days, but the more time passes, the worse the condition
08:18of the infected person becomes.
08:21If you feel something similar after swimming in fresh water, seek medical attention immediately.
08:27The chances of recovery are slim, but it's worth fighting for.
08:30Moreover, there have been cases where prompt medical help saved a person.
08:36It's impossible to detect the presence of these amoebas.
08:39If you're unsure but really want to swim in a lake, try not to dive.
08:44In this case, the amoebas won't have a chance to infect you.
08:48The main thing is to prevent the water from entering your nose.
08:51Even if you want to swim in a pool, make sure the water is well disinfected.
08:58But no matter how paranoid you get after this video, let's calm down a bit.
09:03There are not many cases of infection in the world that involve brain-eating amoeba.
09:08The chances of getting it into your nose are quite low.
09:12You're not always afraid of being attacked by a shark when you swim in the sea, are you?
09:16But still, be careful!
09:29I'm sorry.
09:30It's OK!
09:31What do you think?
09:32You're not always afraid of being attacked by a shark animal.
09:36Which is the real thing?
09:37Yeah.
09:38There's a real thing and that's the real thing.
09:40So that's true!
09:41I was thinking about the mystery of this car but I've never just gone into it.
09:44I think it's the real thing.
09:45That's true.
09:46It's a real thing, and that's true.
09:48So that doesn't get the energy there, but you should do that then.
09:50The way you do, I'm not going to get the energy here.
09:53So that's right, what's going to be that.
09:55Bye.
09:56Bye.
09:57Because that's the cover.
