Under the same rule, how long can you go before you may become unconscious from hypothermia?

• A. 1 Minute
• B. 10 Minutes
• C. 1 Hour
• D. 2 Hours

Answer: (C)

Hypothermia cools the core of the body, and as the core temperature falls, brain function slows until consciousness is lost. Unconsciousness tends to occur when core temperature reaches roughly 28–32°C, and in typical outdoor cold conditions with inadequate clothing, this progression often happens after about an hour. That’s why the one-hour estimate is the best fit for the scenario. Shorter times like a minute or ten minutes would require very rapid cooling (such as in cold water), while two hours is longer than the usual window for losing consciousness in ordinary exposure. Remember, the exact timing depends on temperature, wetness, wind, and clothing, but the hour mark is a common rule-of-thumb for this risk.
