And it has nothing to do with sweat.
Even though hydration is a pretty basic human necessity, the structure of our modern daily lives can make it difficult to down the right amount of water each day. We all have our own tricks for helping ourselves remember to guzzle a minimum of eight glasses in a 24-hour period, but how many ways can we diagnose just how dehydrated we really are?
Enter: Your skin, the largest organ in (or on) your body. It serves countless functions for your overall health and well-being, and one of those functions is its ability to reveal just how hydrated (or dehydrated) you are within seconds.
It all comes down to your skin’s elasticity, or turgor. Thanks to its elasticity, your skin naturally maintains the ability to change shape and return to its normal orientation. But you know what that elasticity relies on? Proper hydration. If you’re lacking water, your skin isn’t nearly elastic as it should be.
So the skin hydration test is simple: Just pinch the skin on the back of your hand to make a little tent shape and hold it there for a few seconds. After releasing it, if it quickly returns to normal, your hydration levels are on point. If it resists and takes a little time to return to normal, you need to reach for that water bottle.
Because it’s non-invasive, painless and fast, you can make use of this test anytime, anywhere. But we find it particularly helpful as the seasons change and our hydration levels seem even more out of whack than usual. We shouldn’t wait to feel thirsty to drink more water, and the urine color test only shows us what we need to know when it’s too late. So when in doubt, just give yourself a little pinch, and you’ll be good to go.
