The ACTUAL process AFTER the body is no longer alive

  • 0:00 - 0:02
    What happens to your body after death?
  • 0:02 - 0:05
    A lot of videos I educate about are about how we live,
  • 0:05 - 0:08
    how the body goes through the dying process,
  • 0:08 - 0:10
    but I don't really talk about what happens to the body
  • 0:11 - 0:12
    after it dies.
  • 0:12 - 0:14
    This video is going to do just that.
  • 0:18 - 0:21
    So, what happens immediately to your body
  • 0:21 - 0:22
    after it dies?
  • 0:22 - 0:24
    It relaxes,
  • 0:24 - 0:25
    like I've been saying,
  • 0:25 - 0:28
    hence why people urinate,
  • 0:28 - 0:29
    have bowel movements,
  • 0:29 - 0:34
    sometimes have fluid come up their nose or out of their eyes or nose,
  • 0:34 - 0:34
    ear,
  • 0:34 - 0:35
    I mean,
  • 0:35 - 0:38
    all of the things in your body that are holding fluids in.
  • 0:39 - 0:40
    Relax.
  • 0:40 - 0:43
    That's why death can be messy sometimes. After someone dies,
  • 0:43 - 0:44
    not always,
  • 0:44 - 0:47
    but sometimes the body relaxes so much,
  • 0:47 - 0:48
    it releases
  • 0:49 - 0:50
    all of its fluid.
  • 0:50 - 0:51
    So, I like to talk about it,
  • 0:51 - 0:54
    so people aren't surprised if that happens,
  • 0:54 - 0:55
    very normal
  • 0:55 - 0:57
    and to be expected sometimes.
  • 0:57 - 0:59
    The second thing that happens,
  • 0:59 - 1:00
    and you probably have noticed this,
  • 1:00 - 1:02
    the body temperature drops.
  • 1:02 - 1:02
    Now,
  • 1:02 - 1:04
    I have noticed personally,
  • 1:04 - 1:06
    just through seeing a lot of dead bodies,
  • 1:06 - 1:08
    that people's bodies are different.
  • 1:08 - 1:10
    Some people will start getting cooler
  • 1:11 - 1:11
    immediately.
  • 1:12 - 1:13
    Some people take a while,
  • 1:13 - 1:14
    maybe an hour,
  • 1:14 - 1:15
    maybe an hour and a half,
  • 1:15 - 1:16
    it just depends.
  • 1:16 - 1:18
    But their body temperature will drop.
  • 1:18 - 1:19
    Technically speaking,
  • 1:19 - 1:22
    the body temperature should drop about 1.5
  • 1:23 - 1:27
    degrees Fahrenheit per hour to eventually match whatever the
  • 1:27 - 1:29
    temperature is in the room that they're in.
  • 1:29 - 1:32
    One thing that I think people don't know that happens is
  • 1:32 - 1:37
    all of the blood will pool downward towards the ground.
  • 1:37 - 1:37
    So,
  • 1:37 - 1:38
    if you let someone
  • 1:39 - 1:40
    lie there for long enough,
  • 1:40 - 1:42
    which we do sometimes,
  • 1:42 - 1:45
    you don't have to hurry up and make sure your loved one leaves the house.
  • 1:45 - 1:46
    So, they're at the house,
  • 1:46 - 1:48
    the body will be laying there and if you turn them,
  • 1:49 - 1:51
    you will notice usually the back of their legs,
  • 1:51 - 1:55
    the whole backside of them will look purple or darker.
  • 1:55 - 1:57
    That's because all their blood is pulling
  • 1:58 - 1:58
    down,
  • 1:58 - 2:00
    gravity is pulling it down,
  • 2:00 - 2:04
    so they will eventually get, have like a darker color tone of skin
  • 2:05 - 2:06
    on their backside.
  • 2:06 - 2:06
    Now,
  • 2:06 - 2:10
    the one thing that everyone knows that What happens is the stiffening of the body,
  • 2:10 - 2:11
    the rigor mortis.
  • 2:11 - 2:13
    People always have questions about this.
  • 2:13 - 2:14
    When does it happen?
  • 2:14 - 2:15
    Why does it happen?
  • 2:15 - 2:16
    So, here it is.
  • 2:16 - 2:18
    Rigor mortis or the stiffening of the body
  • 2:18 - 2:22
    usually takes place within like 1 to 2 hours after death and then
  • 2:22 - 2:27
    worsens and then loosens over the next like 24 to 30 hours.
  • 2:27 - 2:32
    I have seen people become very stiff almost immediately after death,
  • 2:32 - 2:34
    like a few minutes after death,
  • 2:34 - 2:35
    and other people,
  • 2:35 - 2:36
    their body takes longer,
  • 2:36 - 2:38
    so it just depends,
  • 2:38 - 2:40
    but there is a stiffening of the muscles.
  • 2:40 - 2:40
    First,
  • 2:40 - 2:43
    it'll be in the smaller muscles like your eyes,
  • 2:43 - 2:44
    your face,
  • 2:44 - 2:45
    then your neck,
  • 2:45 - 2:48
    then gradually you'll stiffen throughout your trunk
  • 2:48 - 2:50
    and your body going to your extremities,
  • 2:50 - 2:50
    hands,
  • 2:50 - 2:51
    fingertips,
  • 2:51 - 2:51
    toes.
  • 2:52 - 2:53
    So, why does rigor mortis happen?
  • 2:53 - 2:59
    It happens because your body's metabolism stops and it could no longer produce ATP,
  • 2:59 - 3:02
    which is adenosine triphosphate,
  • 3:02 - 3:03
    which is a mouthful for me to say,
  • 3:04 - 3:05
    but it's the body's cellular energy.
  • 3:06 - 3:07
    I want to be very accurate about this.
  • 3:07 - 3:08
    I'm just gonna read it for you.
  • 3:08 - 3:09
    So, it says here,
  • 3:09 - 3:14
    ATP is necessary to break the cross bridges between actin and myosin,
  • 3:14 - 3:19
    two muscle proteins that contract and relax to allow muscles to move.
  • 3:19 - 3:20
    When ATP levels drop,
  • 3:21 - 3:26
    actin and myosin filaments bind together and contract permanently,
  • 3:26 - 3:29
    causing muscles to stiffen and lose elasticity.
  • 3:29 - 3:30
    This is hard for me to read.
  • 3:30 - 3:31
    There you have it.
  • 3:31 - 3:32
    That's what rigor mortis says.
  • 3:32 - 3:32
    So,
  • 3:32 - 3:33
    rigor mortis
  • 3:34 - 3:36
    starts from time of death and then
  • 3:37 - 3:37
    goes
  • 3:37 - 3:40
    over the next 24 to 36 hours,
  • 3:40 - 3:42
    and then eventually the body loosens again,
  • 3:42 - 3:45
    so the body does not stay stiff the whole time.
  • 3:45 - 3:46
    One thing I'd like to mention that most
  • 3:46 - 3:48
    people don't realize that after someone dies,
  • 3:49 - 3:50
    they become very,
  • 3:50 - 3:51
    very heavy.
  • 3:51 - 3:55
    So, cleaning them on your own after they die would be almost impossible,
  • 3:56 - 3:56
    I guess,
  • 3:56 - 3:58
    unless you're much bigger than the person who died,
  • 3:58 - 3:59
    then you probably could.
  • 3:59 - 4:00
    But they are very heavy,
  • 4:00 - 4:03
    so you will likely need help to move them,
  • 4:03 - 4:04
    change them,
  • 4:04 - 4:06
    wash them if that's what you plan on doing.
  • 4:06 - 4:07
    So, like I said,
  • 4:07 - 4:09
    after a day or so after death,
  • 4:09 - 4:11
    the body does loosen again.
  • 4:11 - 4:15
    The body's tissues relax and it causes the stiffness to break down.
  • 4:15 - 4:16
    Usually by this time,
  • 4:16 - 4:19
    the person's body is in the mortuary,
  • 4:19 - 4:21
    and then depending on what you as a family wanted to
  • 4:21 - 4:25
    do with the body is how the mortuary will move forward,
  • 4:25 - 4:26
    whether that's embalming,
  • 4:26 - 4:27
    cremation,
  • 4:27 - 4:29
    there are green burials,
  • 4:29 - 4:30
    it just depends.
  • 4:30 - 4:32
    In a world where people didn't have access to a
  • 4:32 - 4:35
    mortuary or a healthcare system and they just died naturally,
  • 4:36 - 4:37
    our bodies are built
  • 4:37 - 4:38
    to after death,
  • 4:38 - 4:39
    decompose,
  • 4:39 - 4:41
    and this is how the body would do that.
  • 4:41 - 4:45
    So, there are four key stages to decomposition of a body.
  • 4:45 - 4:47
    So, the first stage is called hypostasis.
  • 4:47 - 4:48
    This I actually already spoke about.
  • 4:48 - 4:50
    This is when the person dies
  • 4:50 - 4:51
    shortly after 1 to 2 hours,
  • 4:51 - 4:56
    their blood vessels will collapse and start to pool downwards towards gravity,
  • 4:56 - 4:57
    towards the earth.
  • 4:57 - 5:01
    This causes them to have their blood pool at the bottom or the
  • 5:01 - 5:06
    back of them and causes like a purplish brownish color to happen
  • 5:06 - 5:07
    at the back of their body.
  • 5:08 - 5:09
    It can almost look like one big bruise.
  • 5:09 - 5:09
    Now,
  • 5:09 - 5:10
    it's not a bruise,
  • 5:10 - 5:11
    but it could look like one.
  • 5:11 - 5:13
    The second stage is called algor mortis.
  • 5:13 - 5:16
    This is when the body follows the Newton laws of cooling,
  • 5:17 - 5:18
    which I talked about before,
  • 5:18 - 5:22
    where it drops in like about 1 to 1.5 degrees
  • 5:22 - 5:26
    every hour until it matches the temperature of the room.
  • 5:26 - 5:31
    It takes about 12 hours for the body to feel cool to the touch and 24
  • 5:31 - 5:34
    to actually be cool to its core.
  • 5:34 - 5:36
    So, the core temperature of the body
  • 5:37 - 5:38
    will actually match
  • 5:38 - 5:39
    whatever room they're in.
  • 5:39 - 5:41
    The third stage is called autolysis,
  • 5:41 - 5:44
    also called self-digestion.
  • 5:44 - 5:44
    Basically,
  • 5:45 - 5:50
    enzymes begin to break down oxygen-deprived tissue.
  • 5:50 - 5:54
    This process actually begins and starts only several minutes after death.
  • 5:54 - 5:56
    The last process is called putrefaction,
  • 5:56 - 6:00
    and it usually starts between 4 to 10 days after death.
  • 6:00 - 6:02
    This is when gasses start being released,
  • 6:03 - 6:04
    so there's an odor,
  • 6:04 - 6:07
    there would be discoloration of the skin and the body.
  • 6:07 - 6:12
    black putrefaction occurs between 10 to 20 days after death.
  • 6:12 - 6:14
    When the exposed skin turns black,
  • 6:14 - 6:17
    there could be some bloating and fluids are released from the body.
  • 6:17 - 6:22
    So, this is the part where the body is literally decompensating
  • 6:22 - 6:22
    and
  • 6:23 - 6:27
    how we would die and how the body would die before we had things like mortuaries.
  • 6:27 - 6:29
    So, it's a very normal thing.
  • 6:29 - 6:29
    However,
  • 6:30 - 6:31
    since we really aren't exposed to it,
  • 6:31 - 6:32
    and when we are,
  • 6:32 - 6:35
    it's usually from some kind of dramatic ending where someone finds
  • 6:36 - 6:36
    a body,
  • 6:36 - 6:37
    things like that.
  • 6:37 - 6:40
    But this is a natural part of the body decomposing.
  • 6:40 - 6:44
    So that is the natural process of what happens to a body if we
  • 6:44 - 6:48
    didn't take it to a mortuary to be embalmed or to be cremated.
  • 6:48 - 6:50
    That's why I think it's so important to know
  • 6:50 - 6:51
    what you'd want
  • 6:51 - 6:52
    with your loved one.
  • 6:52 - 6:54
    What do you want after you die?
  • 6:54 - 6:57
    There are different options besides cremation
  • 6:57 - 6:58
    or embalming,
  • 6:58 - 6:59
    burials.
  • 6:59 - 7:01
    There's green burials.
  • 7:01 - 7:03
    There's all different options out there for us.
  • 7:03 - 7:05
    It's just important to be informed and to know what you want.
