Why do Humans get dehydrated so quickly?

654 viewsBiologyOther

Been seeing that you should keep drinking until your pee is clear, but its quite astounding how quickly the pee turns dark. Like just 4h of no water or eating a meal will turn it dark. If water is needed so often how do people of the past (who probably don’t have that frequent access to water) even live?

You’re conflating a few basic facts. Dehydration does not mean you are dying. You’re not dead after 4 hours of not drinking water. Humans can survive 2-3 days without water.

The purpose of replenishing fluids frequently is to maintain optimal hydration – think of it as topping up your fluids. Once you go for a few hours without hydrating, your body begins to deteriorate in function, which you will recognise through symptoms like lack of focus, heads, tiredness, drowsiness, etc. You’re not dying, but you’ll start being cranky and tired.

People in the past did have access to water. There’s a reason why civilisation grew around rivers and lakes.
