How many times does a human blink in one day?
1
Answer
Scientists have shown that the average person blinks 15-20 times per minute. That's up to 1,200 times per hour and a whopping 28,800 times in a day—much more often than we need to keep our eyeballs lubricated. In fact, we spend about 10 percent of our waking hours with our eyes closed.
