The density of the human body is less than that of the water. Therefore, when a human dead body falls in water, it floats for a few seconds in it. But when water goes into the body, its density becomes more and it sinks.

Is it possible for a human to sink in water?
This is, in short Archimedes' Law. A human submerged in water weighs less (and is less 'dense') than the water itself, because the lungs are full of air like a balloon, and like a balloon, the air in lungs lifts you to the surface naturally. If an object or person has a greater density than water, then it will sink.
Do humans sink?
Muscles are generally more dense than water and cause us to sink. Fat is less dense than water, party because it contains oil, which floats on water. ... Those of us with a higher fat to muscle ratio will tend to float. Yes that's right, fat people float better than muscular people - generally speaking.
Will a dead body float or sink?
As a general rule, yes. A cadaver in the water starts to sink as soon as the air in its lungs is replaced with water. ... Most dead bodies float this way, but there are exceptions. The smaller the limbs, the more likely a corpse will float facing up—short arms and legs create less drag.
Why a living person sinks and dead people float?
The general idea is that because a man is alive he can make himself stay above the water whereas a dead person has no abilities, therefore, he has to sink.
Can a person float forever?
“The trick is to not panic; as long as you don't panic, you can float forever, until you are rescued or until you find the energy to swim to shore.”
Does everyone float in water?
With very few exceptions, everyone floats, however most people think they are that exception when in reality 99,9% are not. It is the degree of flotation and how easy it is to float that is influenced by your body's make-up. People usually float to varying degrees and in varying ways.
Why do humans sink?
The density of the human body is similar to the density of water, and what keeps us floating--other than the dog paddle--is the air in our lungs. A corpse begins to sink as the air in its lungs is replaced by water.
Will a body sink in cold water?
The putrefaction of flesh produces gases, primarily in the chest and gut, that inflate a corpse like a balloon. In warm, shallow water, decomposition works quickly, surfacing a corpse within two or three days. But cold water slows decay, and people who drown in deep lakes, 30 metres or below, may never surface.
How long can a dead body float in water?
Even a weighted body will normally float to the surface after three or four days, exposing it to sea birds and buffeting from the waves. Putrefaction and scavenging creatures will dismember the corpse in a week or two and the bones will sink to the seabed.
What does a drowned body look like?
The usual postmortem changes of vascular marbling, dark discoloration of skin and soft tissue, bloating, and putrefaction occur in the water as they do on land though at a different rate, particularly in cold water (4).
Will a dead body float in Lake Superior?
Normally, bacteria decaying a sunken body will bloat it with gas, causing it to float to the surface after a few days. But Lake Superior's water is cold enough year-round to inhibit bacterial growth, and bodies tend to sink and never resurface.
Do fat people float better?
In fact, they float just like normal-sized people do. ... This fact is because fat tissue has a lower density than water. In other words, the reason why fat people float is that “fat” because it's less dense than water. And since obese people have more fat than other persons, they generally float easier.
How much time can a human swim?
We estimate the outer limits of swimming non-stop in the open water without sleep is 80-100 hours and would best be done swimming/floating downstream in a warm-water river that starts in the highlands (not the mountains) and flows out to the ocean in a non-industrial area.
Why can't we float in the air?
Air is made up of lots of /really/ little things, like nitrogen and oxygen atoms. These atoms hardly weigh anything, so gravity doesn't pull on them very hard, but they weigh enough to be held near the ground.
Can some humans not float?
Some people can't float because they are too nervous in the water. Muscular people or people who are lean might have trouble floating too. If you have a low body fat percentage, floating on water might be difficult. But, everyone who can swim can float.
How do skinny people float?
Use your lungs.
1 - Inhale and hold your breath for 5 seconds while treading or floating. 2 - Quickly exhale while kicking harder, as you tend to sink when the air in your lungs leaves. 3 - Quickly inhale and you will feel a more natural float for those 5-6 seconds, allowing you to kick less.
