skin tenting
n.— «There is a simple way to tell if you are dehydrated, Rodriguez said, and it is a technique called “skin tenting.” In this technique, pinch and lift up the skin on the back of the hand to form a tent, then quickly let it go. The amount it stretches is an indication of its extensibility. The faster it returns to normal, the more hydrated you are. The slower it returns indicates you may be dehydrated.» —“Drink up, it’s hot out there” by James Gilbert Yuma Sun (Yuma, Arizona) May 15, 2009. (source: Double-Tongued Dictionary)
