Upon death, the body's physiological processes begin to shut down, leading to a decline in temperature. This natural process is known as algor mortis, where the body cools down to match the ambient temperature of the surrounding environment.

Immediately after death, there is typically a slight increase in body temperature due to certain metabolic processes that can momentarily continue, such as the heat produced by muscles no longer under control. However, this increase is not a sustained rise but rather a short-lived phenomenon before the inevitable cooling begins.

Understanding algor mortis is crucial for forensic science as it helps in estimating the time of death. Initially, bodies may experience a slight rise in temperature due to post-mortem phenomena before they start cooling down consistently, making this concept essential for forensic investigations.
