Why Women Blink Twice as Much as Men

Why Women Blink Nearly Twice as Much as Men

If you've ever been in a staring contest, you might have noticed something odd: women tend to blink way more than men. Like, almost twice as much. Women clock in at around 19 blinks per minute, while men cruise along at a leisurely 11.

So what's going on? Are women just bad at staring contests, or is something deeper at play?

It's All About Hormones (Of Course)

The main culprit is estrogen. This hormone doesn't just influence reproductive health—it also affects your eyes. Estrogen stimulates the production of oils and mucus that make up your tear film, the liquid layer coating your eyeballs. More tear production means eyes need more maintenance, and blinking is how your body spreads that moisture around.

Men have lower estrogen levels, so their eyes don't produce as much tear film. Less maintenance needed = fewer blinks required.

Interestingly, women on hormonal birth control or going through menopause sometimes report changes in how often they blink or experience dry eyes, further proving the hormonal connection.

Testosterone Plays Defense

While estrogen revs up blinking, testosterone might actually suppress it. Men's higher testosterone levels are associated with thicker, more stable tear films that don't evaporate as quickly. Think of it like comparing a puddle to a lake—the lake takes longer to dry up.

This means men's eyes can go longer between blinks without feeling uncomfortable or dry.

Eye Shape and Sensitivity Matter Too

Women tend to have slightly different eye anatomy. Some research suggests women have more sensitive corneas and a greater tendency toward dry eye conditions. When your eyes are more sensitive, your nervous system triggers more frequent blinking to keep things comfortable.

Plus, women are statistically more likely to wear eye makeup, which can irritate the eyes and lead to—you guessed it—more blinking.

When Blinking Goes Wrong

Both excessive and insufficient blinking can cause problems:

Too much blinking can signal anxiety, fatigue, or neurological conditions
Too little blinking (common when staring at screens) leads to dry, irritated eyes
The average person blinks 15-20 times per minute, but that drops to 7 times when using computers

Whether you're a rapid blinker or a stare-master, your blink rate is just another quirky way biology makes us all a little different. And next time someone accuses you of blinking too much, just blame your hormones.

Frequently Asked Questions

Why do women blink more than men?

Women blink nearly twice as much as men primarily due to higher estrogen levels, which increase tear production and require more frequent blinking to maintain eye moisture. Hormonal differences in tear film composition also play a role.

How many times per minute do women blink compared to men?

Women blink approximately 19 times per minute on average, while men blink about 11 times per minute. This represents nearly a 2:1 ratio between the sexes.

Does birth control affect how much you blink?

Yes, hormonal birth control can affect blinking rates and eye moisture. Some women report dry eyes or changes in blinking frequency when starting or stopping hormonal contraceptives due to fluctuating estrogen levels.

Is excessive blinking a health problem?

Excessive blinking can sometimes indicate anxiety, eye strain, fatigue, or neurological conditions, but normal variation between individuals is common. If blinking feels uncomfortable or interferes with vision, consult an eye doctor.

Why do we blink less when looking at screens?

People blink about 7 times per minute when using computers or phones, compared to the normal 15-20 times per minute. This reduced blinking during screen time leads to eye strain and dry eyes, regardless of gender.
