00:00Have you always wondered, why do we blush?
00:02Blushing may be one of the strangest things our bodies do.
00:06It's involuntary, impossible to hide,
00:08and humans are basically the only creatures who do it.
00:11Scientists think blushing is tied to our fight-or-flight response.
00:16Yes, it occurs whenever you're embarrassed, complimented,
00:19or suddenly realize you've had spinach in your teeth
00:22during an entire wedding reception.
00:24And when that happens, your brain goes...
00:26Open the adrenaline floodgates.
00:28Which causes tiny blood vessels in your face to widen.
00:32Blood rushes to your cheeks, and your face declares to the world...
00:35Attention shoppers!
00:37A socially awkward moment now in progress in aisle four.
00:41But here's the really odd part.
00:42You blush because your brain thinks everyone is paying attention to you.
00:47Which, ironically, they probably weren't
00:49until your face turns the color of a fire truck.
00:53Always wondered.
