(Reuters) In general terms, the human body can go two to three days without water and, it is often said in survival guides, 30 to 40 days without food of any kind. (Many of these guides also discourage people from scavenging for wild plants or shrubs because of the adverse effects these can have.)
Now back to the question at hand. How long can you go without water? Assuming you're in reasonable shape and in ideal conditions -- that is, not in the heat or cold and not exerting, a human can probably live for about 3 to 5 days without any water.Healthier humans can live another day or so longer. This isn't something you should test.ssuming you're in reasonable shape and in ideal conditions -- that is, not in the heat or cold and not exerting, a human can probably live for about 3 to 5 days without any water.
