Is blinking solely to keep your eyes moist, or does it play a deeper role in eye and brain health?
- Research estimates we blink around 20,000 times daily. Each blink lasts about 0.2 seconds, closing your eyes for roughly 10% of waking hours.
- Studies suggest women blink more often than men, though findings vary. People with lighter eyes also blink more frequently than those with darker eyes.
- Blinking primarily moistens eyes and protects them from dirt and debris.
- Emotions like nervousness or infatuation can trigger more frequent blinking.
- A study indicates blinking exceeds what's needed for moisture alone. It may function like a brief neural reset, akin to a micro-nap, altering brain activity during those moments.
