What If You Spent 24 Hours Lost at Sea? - YouTube
Channel: What If
[4]
this man
[5]
is about to dive 20 meters off the top
[8]
of a cruise ship
[10]
what will happen to his body when he
[12]
hits the water
[14]
well luckily for him and others
[18]
the impact of hitting the water wouldn't
[20]
be the worst part
[22]
of going overboard the worst part
[25]
would be what would come next being
[28]
lost at sea even if you're wearing a
[32]
life jacket
[33]
surviving all alone in a giant body of
[35]
water until
[36]
someone rescues you will not be easy
[41]
what would be the biggest threat to your
[43]
survival
[45]
how could fish eyes save your life
[48]
and how long would you have before the
[51]
water
[52]
starts breaking down your skin
[55]
this is what if and here's what would
[58]
happen
[59]
if you spent 24 hours lost at sea
[65]
[Music]
[67]
we say 24 hours because it's a nice
[70]
familiar number but the reality is that
[72]
you'll be lucky
[73]
if you even last that long hypothermia
[77]
can set in within minutes
[79]
and dehydration and exhaustion would
[81]
soon follow
[83]
one crucial thing to keep in mind is
[86]
that
[86]
you'd be surrounded by salt water you
[89]
can't drink it but it could save you
[92]
from drowning
[93]
[Music]
[98]
it's a lot easier to drown in fresh
[100]
water than it is to drown in salt water
[103]
about 90 of all drownings occur in fresh
[107]
water
[108]
not only is salt water more buoyant than
[110]
fresh water but
[112]
it's also safer to inhale
[115]
if you're going to drown in salt water
[117]
it's because the water you inhaled into
[119]
your lungs
[120]
stopped you from getting oxygen and
[122]
expelling carbon dioxide
[124]
but with fresh water it can be a little
[127]
more complicated
[129]
fresh water can kill you even after it's
[131]
been removed from your lungs
[133]
when you inhale salt water the higher
[136]
salt concentration
[137]
prevents the water from crossing into
[139]
your lung tissue
[141]
when you inhale fresh water it can enter
[144]
unprotected lung cells and
[145]
make them swell until they burst
[149]
this can lead to such severe damage that
[151]
you might not recover
[153]
even after the water is removed from
[155]
your lungs
[156]
but salt water has its drawbacks too
[160]
if you only have salt water around you
[163]
dehydration can be a major threat
[168]
if the hot sun is beating down on you
[171]
dehydration can begin
[172]
in about an hour you'll be losing water
[175]
from sweating
[176]
urinating and even breathing
[180]
as dehydration sets in you'll start to
[183]
feel extremely
[184]
thirsty dizzy confused and fatigued
[188]
none of that will raise your chances of
[190]
survival
[192]
if you're lucky it will rain rainfall
[195]
will provide a good source of drinkable
[197]
water
[198]
just lay on your back and open your
[201]
mouth
[202]
but if you don't get any rain you'll
[205]
need to be
[205]
a little more creative try to catch a
[208]
large
[209]
fish if you're successful then all you
[212]
have to do is eat its eyes
[213]
[Music]
[215]
big fish eyes are full of watery liquid
[218]
that will
[218]
surely quench your thirst yeah i know
[221]
it's gross but
[222]
there's no time to think about that
[224]
because you still have to worry about
[226]
hypothermia
[228]
[Music]
[233]
generally you can expect to survive in 5
[236]
degree water for
[237]
10 to 20 minutes before your muscles
[240]
will get weak
[240]
and you lose your strength and
[242]
coordination
[244]
this happens because the blood moves
[247]
away from the furthest parts of your
[248]
body
[249]
and towards the core the best way to
[252]
prevent hypothermia
[253]
is to pull your knees up to your chest
[256]
and keep them there
[257]
so that you can retain as much heat as
[258]
possible the less you move around
[261]
is also better for conserving your
[263]
energy
[264]
and not attracting predators as
[268]
you've probably gathered from the past
[269]
few minutes finding yourself in this
[271]
scenario
[272]
would be very bad your best bet at
[275]
surviving in the sea
[277]
is to avoid getting into this situation
[279]
in the first place
[284]
if you're going out on a fishing trip or
[286]
boat remember to tell people where
[288]
you're planning on going
[290]
and when you're supposed to be back
[293]
technology
[293]
is making it easier to find people who
[295]
get lost in water but
[297]
the more information the better when it
[299]
comes to rescue missions
[301]
you'd want to be rescued from the water
[303]
as soon as possible because
[305]
being submerged in water for any longer
[308]
than 24 hours
[310]
can lead to your skin breaking down if
[313]
this happens
[313]
you'll have open sores and you would
[316]
have a greater risk of
[317]
fungal and bacterial infections even if
[320]
the water is completely sterile
[322]
don't believe me well maybe you should
[324]
test it out by
[326]
sitting in a full bathtub for a few days
[328]
straight
[330]
but that's a story for another
[333]
what if
[337]
