Things That Happen to Your Body After You Die

The heart stops beating and blood pools
The moment the heart stops beating is what doctors officially regard as the time of death. Once it stops, the rest of the body begins to die, albeit at different rates. With the heart no longer pumping, the first thing to happen in the process of death is that our blood stops flowing and pools wherever it is in our veins and arteries.

Our bodies change colors
With our blood suddenly non-mobile, our bodies begin to change color. Part of our bodies change to purplish-red or bluish-purple because the blood settles, due to gravity, in the lowest part of our bodies. Other parts turn deathly pale, since the blood (reduced hemoglobin, to be exact) is less concentrated or more drained in those areas.

Livor mortis helps forensics solve cases
Forensic investigators can use this phenomenon, known as livor mortis, to tell if a body has been moved since death because after death our blood congeals in our blood vessels, like a layer of fat which congeals on top of homemade stock or fried foods.

Algor mortis cools the body temperature
The second most popular form of mortis, algor mortis is next thing that happens to our bodies when we die. Known as “death chill”, our bodies lose their 98.6°F (37°C) warmth and slowly acclimate to the ambient room temperature, losing about 1.5°F (0.8°C) per hour.

Rigor mortis sets in
The better-known rigor mortis does not happen until a few hours after the moment of death. The process starts with the eyelids and neck muscles, followed by the entire body, stiffening up due to the depletion of ATP (adenosine triphosphate): the chemical responsible for relaxing muscle fibers after a contraction.

Our bodies can twitch
In what must have scared earlier peoples and made them believe in the undead, our bodies can twitch and flex for hours after death. As muscle tissues die, they can contract. If enough contract, a visible muscle twitch or reflex can be seen, making it seem like the corpse is trying to regain consciousness.

The skin on our face flattens out
In a bizarre perk for Botox-loving people everywhere, our faces get an immediate free-injection of Botox when we die. Well, not exactly Botox, but since our muscles are no longer contracting, the wrinkles on our faces mostly disappear.

Our hair and nails don't keep growing
A commonly-held myth states that our hair and nails continue growing after death. In fact, after our bodies die, our skin loses moisture, causing the skin on our entire body to shrink. The shrinkage exposes more of our nail cuticles and hair follicles, making them appear longer.

We void our bowels
Commonly joked about on sitcoms, this fact does actually happens to our bodies when we die. As rigor mortis is affecting most of the body, some parts (sphincters, more accurately) are being loosened. Since the brain keeps our bodies’ sphincters closed as part of its regulation of involuntary functions, when the brain shuts down, the sphincters open, leading a corpse to rid itself of urine or feces left in the body.

Our bodies secrete putrid odors
To no other object does “putrid” better apply than to a corpse. As our cells die, they release enzymes notifying local bacteria and fungi of the event. The bacteria and fungi rush in to begin decomposition, releasing noxious and putrid gases and odors.

Animals rush in to devour the body
Beyond the bacteria and fungi, blowflies and flesh flies are attracted to the sweet odors put out by a corpse. The flies lay eggs which hatch into maggots which start eating away at the dead flesh. Other creatures such as mites, ants, spiders, and vultures also descend upon the body.

Our bodies can moan
A post-mortem effect which scares even modern-day doctors and nurses, our bodies can make sounds after death! The combination of rigor mortis (including the vocal cord muscles) and gas secreted by bacteria in our guts can lead dead bodies to fart, squeak, and even moan.

The immune system shuts down
Our bacteria-rich guts become a breeding ground for a massive explosion of bacteria. Once our immune system shuts off, our gut bacteria begins digesting our intestines before spreading to other organs.
