Caskets Can Potentially Explode. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water. BODY DECOMPOSITION TIMELINE. Blood pools at the lower parts of the body. The body's tissues then begin to break open and will release gas and other fluids in the same way as a fruit that has been left too long in the sun. Sort your garbage on a timeline to better understand decomposition. A protected body may also limit insect activity, resulting in a slower rate of decomposition if insects cannot easily access the corpse, in addition to retaining body heat. Liquids settle in the tissues, creating lividity, or discoloration on whichever side of the body faces downwards. 24-72 hours after death — the internal organs decompose. How quickly a body decomposes depends on several factors: surrounding temperature, whether the body is buried or exposed to air or water, and the number of bacteria present.
