Here’s a playful one: Press your thumb into the top of your other hand for five seconds. When you lift it, does a white mark remain for more than a second? Some people swear this indicates dehydration. Is it 100% scientifically proven? Debatable. But it’s fun.
Consider it a friendly reminder. If your thumb leaves a ghostly little crater, just have a sip of water. No pressure, no stress. Worst case, you get a hand massage out of it.
