In dense, salty water, a little body displaces a lot of mass, and most of the body stays out of the water so, it’s hard to drown a person when most of their body is floating on top of the water. The Dead Sea water has a density of 1.24 kg/litre, which makes swimming similar to floating.

What are floating and sinking?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.
