How Does a Body Decompose in Water


Have you ever wondered what happens to a human body after it’s been submerged in water? Most people assume that the body simply decomposes like it would on land, but there are actually several factors that contribute to how a corpse breaks down underwater. Let’s take a closer look at how a body decomposes in water.

The first thing to keep in mind is that the type of water makes a big difference. For example, saltwater accelerates the process of decomposition because it’s full of bacteria that can break down flesh. Freshwater, on the other hand, doesn’t have as many microorganisms, so decomposition happens more slowly.

Temperature also plays an important role in how quickly a body decomposes underwater. In warm water, bacterial activity increases and the rate of decomposition speeds up. In cold water, however, bacteria activity slows down and the process takes longer.

Finally, the depth of the water can also affect how quickly or slowly a body decomposes. If a body is submerged in shallow water where there’s still contact with air, decomposition will happen more quickly than if it were submerged in deep water with no access to oxygen.

When a body decomposes in water, it starts to bloat as gases are produced by the bacteria that are breaking down the tissues. The body will float at first but then sink as the gas is released and the tissues start to break down. The skin will become wrinkled and pale and the eyes will sink into the sockets.

The hair and nails may fall out as well. As decomposition continues, the soft tissues will be eaten away by fish and other aquatic creatures and eventually all that will remain is the skeleton.

How Long Does It Take for a Human Body to Decompose in Water?

The decomposition of a human body in water is a process that takes place over several months. The rate at which decomposition occurs depends on a number of factors, including the temperature of the water, the level of oxygenation and the presence of scavengers. Initially, when a body is first submerged in water, bacteria that are already present in the gut begin to break down tissues.

This process accelerates as more bacteria from the surrounding environment colonize the body. autolytic enzymes produced by cells also contribute to tissue breakdown. As decomposition proceeds, different bacteria predominate and produce different gases.

This results in characteristic changes in both the appearance and odor of the corpse. For example, early on in decomposition there may be an effervescent greenish-black foam produced by gas bubbles escaping from putrefying tissues. This is followed by a change to a reddish-brown color as blood is broken down and released into the water.

The final stage of decomposition is characterized by complete skeletonization as all soft tissues have been degraded or consumed by scavengers. Depending on environmental conditions, this process can take anywhere from weeks to years.

Do Human Bodies Decompose in Water?

Yes, human bodies do decompose in water. However, the rate at which they decompose varies depending on a number of factors, including the temperature and pH of the water, the amount of oxygen present, and the presence of other decomposing materials. Generally speaking, warmer water temperatures will accelerate decomposition, while cooler temperatures will slow it down.

Additionally, higher pH levels (i.e., more alkaline) will also speed up decomposition, while lower pH levels (i.e., more acidic) will have the opposite effect. The amount of oxygen present is also an important factor to consider. In well-oxygenated waters (such as rivers and streams), bacteria that consume organic matter for food are able to thrive and break down bodies relatively quickly.

In contrast, stagnant or poorly-oxygenated waters (such as ponds or lakes) can retard decomposition significantly due to the lack of available oxygen for bacteria to perform their functions. Finally, the presence of other decomposing materials can impact how quickly a body breaks down in water. If there are already significant amounts of other organic material present in the water (such as leaves or fish), this can provide a ready food source for bacteria that would otherwise be breaking down human tissue.

As such, these other materials can cause human bodies to decompose somewhat slower than if they were present in isolation.

What Does a Body Look Like After Being in Water for 2 Weeks

What Does a Body Look Like After Being in Water for 2 Weeks When someone drowns, their body goes through a number of changes. The first thing that happens is that the person starts to gasp and take in water instead of air.

This water then fills up the lungs and the person starts to experience what is called “wet drowning.” Wet drowning is when the lungs are filled with fluid and can no longer exchange oxygen and carbon dioxide effectively. The person will then become unconscious and their heart will stop beating.

Once the heart stops, blood flow to the brain also stops and death quickly follows. The changes that happen to a drowned body after death are largely due to the effects of water on tissue. Water is heavy and it puts pressure on all of the organs in the body which causes them to start breaking down.

The skin becomes wrinkled as all of the fluids in the body start to leak out into the surrounding water. The eyes sink back into their sockets and often pop out completely as well due to this same pressure differential between inside and outside of the eye ball. Internally, all of the organs swell up as they fill with fluid from within the body cavity itself.

Finally, bacteria starts to break down any remaining tissues leading to decomposition. So, after two weeks in water, a human body would be unrecognizable due its bloated state, sunken eyesockets ,and wrinkled skin . It would smell bad too because of all bacterial growth occurring throughoutthe corpse .

In some cases , however , depending on environmental factors suchas temperature or currents , bodies can mummify which slows decomposition significantly .


When a body decomposes in water, the process is called aqua purga. The first stage of decomposition is called putrefaction. This is when the body starts to break down and release gases.

The second stage is called saponification, which is when the body starts to dissolve in the water. The third and final stage is called mineralization, which is when the body turns into minerals and sediment.
