The Effect of Mud on Body Temperature

In the movie, Arnold is covered in a clay-like mud slime. A thermographic camera found that it would only work for a very brief amount of time until the mud heated up from the human body temperature underneath it. The 2022 film Pray cleverly adapts this having our hero in this movie instead of covering themselves with mud, they ingest a traditional medicine which lowers one's body temperature through medicinal means and is able to then give the hero the same advantage over the predator.
