How long can a human survive on just water?

Answer 1

A human can go up to a month without food. The body cannot go very long without water. A human can only live up to a week without water.

Answer 2

I'm not completely sure, but you probably couldn't live on only water because you will need to eat. I believe you can go about 72 hours without food...

Answer 3

It depends on the conditions in the environment. On very hot days, the time is shorter. But 100 hours in temperate temperatures is about as long as possible.

Answer 4

Till he dies

Answer 5

3 Days
