Is water less dense than the human body?
The average human body has a density of 1.010 kg/litre
The density of pure water is exactly 1 kg/litre
The density of sea water is 1.025 kg/litre
So the average human is denser than fresh water but less dense than seawater.
There are significant differences in density between people, women tend to be less dense than men, muscular people tend to be more dense, fat people tend to be less dense. We can also reduce our density by breathing in deeply.
Incidentally dead bodies tend to float after a few days due to the build up of decomposition gases within the body reducing its density.

Most people can just about float in water what does this tell you about the density of the human body?
Well both a dead body and living one floats on top of water. But the more you panic, the faster you will sink. If you were to stay calm and relax, you will have no problem with floating on top of water.... this is because of density. Anything less dense than water will float and anything more dense than water will sink. Our bodies(YOU CAN BE 600LBS) have a density less than water....so we will…
