    That one is about extremes.

    If you are in sub zero Celsius temps without proper clothing three hours is plenty to kill you especially if there is windchill in play.

    On the other extreme three hours in full sun with a heat index above 40 can cause heat stroke or dehydrate you enough to be deadly as well.
