How long does it take for a body to float after drowning, and how long does it take for a person to

The specific gravity of the human body is slightly larger than that of water. After soaking in water, the density becomes smaller, and the air in the body is added, and it will naturally float. Since the specific gravity of muscle is much greater than that of fat, fat people have a smaller specific gravity and are easy to float, and the situation you are talking about must be a fat person!

The density of human beings is not about the same as that of water, so they can float on the surface of the water when they are alive, but they have to expose their heads in order to breathe, so they lose their balance and will sink.

These things are necessary after death, so it will be natural and comfortable to float on the water.

In addition, the corpse will swell after soaking in the water, and the density will become smaller, making it easier to float on the water.

In addition, after death, some biochemical reactions will occur in the corpse, releasing gases, thereby reducing the density.

When you drink water, you will naturally float up.

It's scary, hopefully it's a movie.

Depending on the length of time of death, the time for the corpse to float is determined.

Because it floated and fluttered and floated and floated, it was discovered, roaring.

You're asking the wrong place! Thank you! It's scary! Find a medical examiner!

It takes 24 hours for a person who can't swim to surface after jumping into the river to commit suicide. If people commit suicide by jumping into the river, they can't swim, they won't float up right away, they will wait for their bodies to swell, and they will float when they lose weight, and in the summer, the temperature is a little higher, the time will be shorter, and it will take about nine hours, and the density of people is very similar to that of water. <>

When people enter the water, there will be air in the lungs, at this time people can float on the water, but people who can't swim will be in the water, drinking water leads to a decrease in the gas in the lungs, and finally becomes zero, at this time the density of people will be greater than the water, and people will go down, after a period of time, after the decomposition of microorganisms in the body, the density of people will change, and it will float up again if it is greater than water, and the time to surface will probably be about 12 hours to 24 hours, people have a saying, Nowadays, many people who die in the water, most of them can swim, and this statement is completely true. <>

Now children's data shows that 70% of recent children can swim, self-rescue and swimming are not exactly equal, we are drowning, strive for more rescue time, first let yourself float up, if we are in the water, don't be nervous, head up and hands on the sides, head up to breathe better deeply, when you take a deep breath after the lungs are full, the alveoli will float up, slowly lift the body up, this time can not shout for help, Instead, hold your breath and save yourself some time. <>

You can also make a lifebuoy by yourself, accidentally fall into the water, floating will be particularly tired, find a piece of clothing to tie the clothes together, hang around the neck, so that there is air in the clothes to grasp with your hands, so that it is a temporary swimming ring, so that you can save your life with this method. If it is a very chaotic time, if you want to break free, after being entangled in fish grass, you can't be nervous, you have to look for opportunities, get out as soon as possible, you can't struggle, the more you struggle, the tighter it will be, if we have leg cramps in the water, break your toes straight and cramp, you can also solve the head surface, take a deep breath, put your body in a ball in the water and break your toes straight for cramps, it's okay.
