Do women blink their eyes more often than men?

This is actually a common myth. Men and women usually blink at identical rates. However, one study showed that women on birth control pills blinked 32% more.

Researchers from Oregon studied this by observing the eyes of 59 males and 86 females. Forty-four of the females were taking birth control pills. After observing their eyes for five minutes, they found that men and women (who weren’t on birth control), blinked at comparable rates of 14.5 times a minute and 14.9 times per minute, respectively.

However, the women who were taking birth control pills blinked 19.6 times per minute! We’re not sure why. It’s possible that the pills affect the caudate nucleus, our brain’s control center for involuntary blinking. In fact, animal studies have shown that blink rates are influenced by the amount of dopamine that travels to that section of the brain. Although we don’t know if or how birth control increases dopamine levels, this shows how the intricacies of the body are still sometimes very much a mystery to us physicians.
