“Rule of Threes”

“Survival experts apply the “rule of threes” to lasting without essentials. You can go about three weeks without food, three days without water, three hours without shelter, and three minutes without air. However, the “rules” are more like general guidelines. Obviously, you can last a lot longer outside when it’s warm than when it’s freezing. Similarly, you can last longer without water when it’s humid and cool than when it’s hot and dry.” []

  • 3 weeks without food
  • 3 days without water
  • (3 days without sleep)
  • 3 hours without shelter
  • (30 minutes in frigid water can make you numb and helpless)
  • 3 minutes without air
