How long can a human go without water?
How long can a human go without water?
Remember the rule of 3s for survival:
3 minutes without air
3 hours without shelter
3 days without water
3 weeks without food
3 hours without shelter?
I’ll accept the others but that one’s just cobblers.
Weather extremes. Blizzards, deserts, hurricanes, life rafts… If you’re stranded on a cool summer afternoon, obviously you can be outside for more than 3 hours, but without shade you might get a sunburn.
It’s meant as a survivalist priority list. Build a shelter, find water, make fire if you can. Food can wait until tomorrow or the next day.
Been there, done that. That’s why I questioned the 3 hours thing. Then again my training/service was temperate and jungle.
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.
Still sounds implausible and far fetched. Why would you be outside without adequate clothing? (Also below zero can be fine in jeans and sweatshirt if the sun is shining and there isn’t much wind). And in that case it would be more a heat issue and less like a shelter issue.
The other case also sounds more like a heat/water issue and less like a shelter issue.
I’ve seen that before and the 3 hours without shelter always cracks me up. Someone really needs to come up with a suitable replacement for the 3 hours part.

Heat index above 40? That’s ridiculously low. 80 degrees F and 40% humidity is an 80 index and that’s perfectly comfortable weather. Heck, I used to work manual labor outside for 8 hours per day in a heat index of 136+. It wasn’t fun, and I was hot as fuck, but I did it every day.
It is a good death.
