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. Once submerged, the body stays underwater until the bacteria in the gut and chest cavity produce enough gas—methane, hydrogen sulfide, and carbon dioxide—to float it to the surface like a balloon.
Do all humans float in water?
Hicks explained not everyone can float — it depends on body density and their ability to displace enough water to float . People with smaller or muscular body types tend to have trouble. RelaxNSwim further explains fat is less dense than muscle and bones, so fat floats more easily.

Why do I sink when I try to swim?
Many swimmers have the tendency to hold their breath when swimming instead of exhaling into the water. ... By keeping your breath in, the air in your lungs creates extra buoyancy in your chest. This will lift you up at the front, which can cause your legs to sink as you lose your streamline body position in the water.
Why do my legs sink when I try to float?
People with a high muscle-to-fat ratio tend to have dense legs, which resist floating horizontally. Because dense legs are less buoyant, they tend to sink, increasing drag . Practicing kicking drills to improve your kick will help you gain additional lift and propulsion to help counteract sinking legs.
How do people drown?
