12 Things You’ve Always Incorrectly Believed About Dead Bodies

Your hair and fingernails do not keep growing after you die. This is false. Fingernails need new cells and glucose to grow. When you expire, your body stops making glucose. Therefore, your fingernails cannot grow.

Hair faces the same issue. Hair grows from burning glucose. When your heart stops pumping oxygen, cells cannot form or divide for long. Thus, your hair stops growing around the time you pass.

Why do these myths persist? Part of the reason involves hair and fingernails.These things appear to continue growing.The skin and flesh around hair follicles and nails recede after some time. This makes hair and nails look longer, even if they have not actually grown.This happens because the skin and flesh around hair follicles and nails start to pull back.This receding skin makes hair and nails look longer, even though they haven't grown.

People tell stories that bodies get stiff after death, but the reality is more complex. One factor is rigor mortis.Rigor mortis, the process that stiffens your body, can take up to 12 hours to set in. After that, muscle contraction keeps your body rigid, but it does not last forever.The process making your body stiff takes up to 12 hours to finish. Then, rigor mortis makes your body rigid by tightening all your muscles. But this does not last forever.

About 18 hours later, rigor mortis begins to reverse. Muscles lose their tightness and stop contracting. This lets your body become floppy and relaxed again in two days or less, like it was at death.

Some traditions demand a coffin for burial. The coffin movement believes burying a body without one pollutes groundwater.

However, burial methods matter little. We generally bury bodies three to four feet down, away from water sources. Groundwater flows much deeper, at 75 feet. Minerals and microorganisms break down chemicals from cadavers between the body and the water.

If fluids leak out, whatever toxic substances escape are neutralized before reaching the deep groundwater.

Stories exist about bodies frightening morgue workers. Tales from hundreds of years ago claim a worker found a recently deceased person sitting up on a table.

The reason for this is that bodies hold many gases.These gases can cause muscles to contract. This forces the body to stand up stiff, as if it were alive.The body bolts upright because these gases cause muscle contraction.

But the story is false.The story is falseAfter expiring, the body fills with gases and must expel them through the anus, even groaning. Your muscles may also twitch.Muscles might twitch.To sit up, you need your stomach muscles to work together. They must hold you upright. The body is not alive; it cannot do either.

We embalm bodies because we thought embalming kept the public safe for a long time. That is not true, according to the Funeral Consumers Alliance.The Funeral Consumers Alliance.Embalming offers no public health benefit. Most places do not require it, and some outlaw it if the body has contagious diseases.

People usually embalm bodies for religious or personal reasons, or to make the body look better for viewing.

The embalming process itself is dangerous. Workers use highly toxic chemicals and must cover their entire bodies and wear a respirator to stay safe.

Scattering ashes is a wrong term. Burning a body happens in a cremation chamber, also called a retort.retortThe retort burns at a very high temperature. Unlike wood ash, bodies have many components. Only a few components remain as material during cremation.

Most of the body is water. As the fire burns, this moisture vaporizes, leaving mostly bones. These bones harden in intense heat, flake, and crumble. After burning, everything left goes into a cremulator, which crushes the bones into a substance like gravel.

Most urns hold a substance that looks more like road-paving material than fine ash.

Embalming, even now, often looks like an in-depth ceremony.An in-depth ceremony.The reality is much simpler. However, embalmers do not remove all organs.

Embalming and autopsy are totally different procedures.Autopsies happen only for medical or legal reasons, or when asked. They can involve weighing, studying, and dissecting organs. Even then, a pathologist or doctor usually places organs back in the body before embalming or burial, not the embalmer.Autopsies happen only for medical or legal reasons, or when asked.

Ancient people and today's people believed cadavers spread disease and make people sick. This long-held belief is wrong. There is no science supporting the idea that a corpse is dangerous or spreads disease just because it is not living. Breathing air around cadavers does not harm you.Cadavers pose a danger to public health.cadavers are dangerous to public healthNo science supports this.There is no science to support the notion that a corpse is dangerous or spreads disease just because it is not living. Breathing air around cadavers will not kill you or make you sick.

This idea about cadavers being dangerous is a problem, especially for disaster relief.Disaster relief.During a huge disaster, people rush to bury bodies quickly to stop disease spread. This shifts focus from relief work. Microorganisms causing decomposition do not spread disease or cause illness.Bacteria and viruses expire within a day after life ends.Exceptions exist. The Ebola virus stays active in dead victims, making their bodies very dangerous. You must bury them quickly.

HIV is one such exception.HIV does not spread.HIV can live in a cadaver for up to 16 days if it stays refrigerated. Most blood-borne pathogens are not a major risk if you use proper hygiene and safety.

This idea makes embalmers sound like evil vampires or mad scientists. Embalmers do not try to suck out all your blood. They use a pushing motion instead.

Blood must be removed, but embalmers push it through as they inject fluid. This moves the blood still in your veins because the circulatory system loops. This process is calledArterial embalming does not remove all your blood.This procedure uses minor cuts and incisions.

Other parts of you have fluids and gas that must exit. Embalmers use a trocar tool to remove this waste and excess fluid. This involves only a small cut; there is no sucking out.

People think that once blood is pushed out and organs have excess gas and fluids removed, they are toxic waste. This belief might come from thinking cadavers harm health. Or perhaps it comes from when embalming happened at home. That idea is no longer true.

Modern embalming practices send our blood and fluidsRemoved bodily fluids go straight into the sewer.The process mixes blood and fluids with strong disinfectant chemicals. This causes environmental damage, though they are not a direct public health threat.

We often picture corpses as pale, ghostly things, sometimes blue or gray. Art and film usually show them this way. That is not always accurate.

Skin color depends on how you died. If you passed on your back, blood and fluids pooled there during livor mortis. If you passed face down, your face and front might turn very red, even purple. Even so, asThe natural process of decomposition makes corpses not always pale.begins, the bacteria in your intestine will turn your midsection green.

When blood vessels in your body break down, your body starts to marble, showing purple lines and bruises where your veins were. Then, the skin turns black.

People believe bodies are toxic. They also think one can ruin the ecosystem they inhabit. This myth is wrong. When an unembalmed body is buried, the remains actually create their own biome, called aThe necrobiome affects the soil.This biome attracts all kinds of fungus and bacteria. This explains why old burial mounds stay green and thrive now.

Therefore, a movement called "green burials" is growing. People bury without embalming. Embalming fluids contain chemicals unfriendly to the soil. This burial method actually helps the ecosystem.
