Do You Get Wetter Walking or Running in The Rain?

You finish dinner at a restaurant, and it’s suddenly pouring. You gaze at your car parked not so far away. Is it better to walk or run in the rain?

Believe it or not, scientists have debated this for years.  If you run you get there faster, so less rain hits you.  But meanwhile you’re slamming more frontwise into the droplets, making them preferentially strike your chest and legs.  If you’d walked, they’d mostly hit your head and shoulders, which offer less surface.

Is this logic correct? Do you get wetter walking or running in the rain?



In the late eighties, an Italian physicist calculated that running through a rainstorm would keep you 10% drier than walking.  Barely any difference. Hardly worth the effort, especially since you’d be more likely to slip and fall.  Then, in 1995, a British researcher decided that walking is better because the drenching of your entire front side would negate the slight benefit of getting there faster.

The next year, two North Carolina climatologists put the whole issue to an actual test.  They each wore identical clothing and water-measuring equipment. One of them ran 100 meters through a downpour while the other simultaneously walked.  Result?  The one who walked was 40% wetter.

Bottom line: Run to the car.

But you already instinctively knew that, didn’t you?

Now, did you know water shouldn’t be wet? I’ll explain why water—beyond its obvious life-giving properties—is truly astonishing.
