Algor mortis is a topic that has generated great interest in today's society. Over the years, this topic has become relevant in different areas, from politics to popular culture. There are divided opinions on Algor mortis, with some considering it positive while others seeing it as a problem. However, it is important to thoroughly analyze all facets of Algor mortis to understand its true impact on society. In this article, we will explore different perspectives and address key aspects related to Algor mortis, with the aim of offering a complete and enriching view on this topic.
Algor mortis (from Latin algor 'coldness', and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched. This is generally a steady decline, although if the ambient temperature is above the body temperature (such as in a hot desert), the change in temperature will be positive, as the (relatively) cooler body acclimates to the warmer environment. External factors can have a significant influence.
The term was first used by Bennet Dowler in 1849. The first published measurements of the intervals of temperature after death were done by John Davy in 1839.
Applicability
A measured rectal temperature can give some indication of the time of death. Although the heat conduction which leads to body cooling follows an exponential decay curve, it can be approximated as a linear process: 2 °C during the first hour and 1 °C per hour until the body nears ambient temperature.
Generally, temperature change is considered an inaccurate means of determining time of death, as the rate of change is affected by several key factors, including:
Stability or fluctuation of the ambient temperature.
The thickness (i.e. thermal insulation value) and body coverage of clothing or similar materials.
