It’s been known for some time that when people blink it’s to moisten their eyeball. It's something the body does without us thinking about it. New research in Japan suggests blinking does more than that by putting the brain in a temporary ‘safe’ mode like a computer does. Volunteers watched ‘Mr. Bean’ videos and observed blinking and results showed when people blink the brain went in to a default mode which is usually used for daydreaming.

When subjects had to focus more, another region of the brain took over, the attention network.  Researchers concluded that involuntary blinking causes your attention to disengage for a few seconds.
