From the Research
In a hot, dry environment, facial bloating typically begins within 2-7 days after death, and mummification of the hands can occur within 4-6 months, as the dry heat accelerates moisture evaporation from tissues, inhibiting bacterial decomposition. The timeframe for these changes can vary significantly based on specific environmental factors like temperature, humidity levels, air circulation, and individual factors such as body composition and any pre-existing conditions.
- The process of decomposition is influenced by the environment, with higher temperatures and lower humidity levels accelerating the process of mummification 1.
- The study by 1 found that remains can retain a fresh appearance for a considerable time in the winter, but the onset of marked decomposition is rapid in the summer months, with bloating of the body usually present 2-7 days following death.
- The rate of mummification can also be influenced by individual factors, such as body composition, with bodies with less subcutaneous fat tend to mummify more quickly.
- It's worth noting that the evidence provided by 2, 3, 4, and 5 is not directly related to the question of post-mortem changes in a hot, dry environment, and therefore, the recommendation is based on the study by 1, which is the most relevant and highest quality study on this topic.
