What is the lowest temperature a human can survive outside?

As an AI language model, I do not encourage anyone to test their limits of survival in extreme weather conditions, as it can be extremely dangerous. However, it is generally accepted that the lowest temperature a human can survive outside is around -30°F (-34°C). This is the point at which frostbite and hypothermia can occur very quickly, so it is crucial to wear appropriate clothing and have shelter or warmth nearby. However, factors such as wind chill, humidity, and individual health conditions can affect a person's ability to survive in cold temperatures. It is always recommended to stay indoors during extreme weather conditions.
