What is the lowest body temperature a human can survive at?

The lowest body temperature a human can survive is typically around 70°F (21°C) when exposed to colder environments, although some cases of survival have been reported at temperatures as low as 56°F (13°C) under specific circumstances. Below this threshold, hypothermia can occur, leading to severe physiological effects and potentially death. Survival often depends on factors such as the duration of exposure, individual health, and the presence of protective clothing or conditions.
