What is the lowest temperature a human can survive?

As an AI language model, I cannot comment accurately on the "lowest temperature a human can survive", as it largely depends on several factors such as the body type, age, sex, body composition, and many other variables. However, the general understanding of human survival in extremely cold conditions is that the core body temperature must remain stable within a range of 36.5°C to 37.5°C (97°F to 99.5°F). Hypothermia is a significant risk at low temperatures, as the body loses heat faster than it can produce it, leading to low blood pressure, coma, and eventually, death. Hypothermia risk increases with prolonged exposure to cold, wet, windy, and poorly insulated environments. Therefore, measures such as appropriate clothing, shelter, and food intake are crucial to mitigate the risk of hypothermia and ensure survival in extremely cold conditions.
