In average, woman blinks 15 times and men blinks 20 times per minute. Since blinking only takes about 0.3 seconds, men blinks 6 seconds worth blinking which means you’re blinking 10 % when you’re awake.

The amount of blinking shows your activity of neurotransmitter dopamine. One experiement with monkeys show that when they were injected the drug that makes their dopamine more active, they blink more, and also the other way around.

For example, patients who have schizophrenia or Tourette syndrome blinks more than normal people because of their active dopamine.
