Quick check: Are your hands or feet tingling? Do you feel disoriented, like you just woke up from a weird nap? Try this: pinch the skin on the back of your hand. If it stays “tented” for a second, you’re actually dehydrated. If it snaps back immediately and you feel sloshy, you might be over-hydrated.
Another fun test: Check your lips. Are they dry? Probably need water. Are they chapped but puffy? That could be early water swelling. Wild, right?
