"Simply squeeze the skin on one of your finger knuckles for a moment, then let go. If you’re well hydrated, the skin will return to its original position immediately, Raj said. But if you’re dehydrated, it loses its elasticity and will stay in a pinched or “tented up” position for a moment, he added."
