Reply to comment by illessen in ELI5: why do our bodies randomly act like we haven’t had water in days and that we need to chug a bunch randomly? by Serratedlily

That’s not true. Dehydration means you are taking in less water than you are losing to the point that your body isn’t working well. The first signs of mild dehydration include thirst, but also headaches, muscle cramps, dark urine, cool dry skin.

If you are just thirsty, you should drink some water. But just being a little thirsty doesn’t mean you are in danger of anything.

The first signs of dehydration are not headaches and muscle cramps lol that's when you're already well into it. Your physical and mental performance will have already been reduced by the time you feel thirsty. If you're correctly hydrating you won't experience any symptoms whatsoever

….if you’re correctly hydrating you won’t be dehydrated. So of course you won’t experience symptoms of mild dehydration!
