How long can a person survive without water?

We can’t live on air and sunshine alone. The human body needs food and water to survive.

A human can go for more than three weeks without food (Mahatma Gandhi survived 21 days of complete starvation), but water is a different story.

At least 60% of the adult body is made of it and every living cell in the body needs it to keep functioning. Water acts as a lubricant for our joints, regulates our body temperature through sweating and respiration, and helps to flush waste.

The maximum time an individual can go without water seems to be a week – an estimate that would certainly be shorter in difficult conditions, like broiling heat.
