How long can the human body survive without food vs. without water?
The body can last weeks without food, but only days without water.
What factors influence the amount of water a person needs?
Body size, gender, metabolism, age, weather, food intake, and activity levels.
What is dehydration?
It occurs when fluid loss exceeds intake, and the body doesn’t have enough water for normal functions.
