3 daysIn a harsh environment — it's snowing, say — you have 3 hours to survive without shelter. After 3 days, you need water or you'll perish. You can make it 3 weeks without food, though we promise you that won't be fun. Despite this possibly helpful rule, some people have survived 8 to 10 days without water.
