How do circadian rhythms influence the estimation of the time of death?

Circadian rhythms play a crucial role in regulating various physiological processes within the body, including the fluctuations in body temperature that occur throughout the day. When estimating the time of death, forensic experts often rely on changes in body temperature as a key indicator. After death, the body begins to cool at a predictable rate, influenced by environmental factors and the individual’s circadian rhythm prior to death.

Understanding how these rhythms affect body temperature allows forensic professionals to make more accurate assessments regarding the time of death. For example, if a person passed away in the early morning hours, their body temperature would have been influenced by the lower temperatures typical of that time of day. Therefore, the regulation of body temperature changes due to circadian rhythms directly impacts the estimation process, making this option the most relevant in understanding post-mortem changes.
