Your Body Is An Ecosystem After Death

When you die, your internal microbes begin a massive migration. Freed from your immune system, these gut bacteria travel through your bloodstream to decompose your body from the inside out.

This process creates a specialized community known as the necrobiome, where your own internal organs become an active habitat. As these microbes feast, they release gases that cause the body to bloat until the internal pressure forces them back out into the environment. Scientists can now analyze these specific microbial shifts to accurately calculate the exact time and location of death. It is a biological transition that turns a former life into a complex, temporary ecosystem.
