With all the things our brains have to constantly process, it is fair to say that they might often need a much-deserved break. Thankfully blinking is here to the rescue about 15 to 20 times per minute. According to a study, that miniscule moment of shut-eye helps the brain to power down and go on a mental break for a split second before attention being restored once again. Therefore, according to scientists, we blink more when we are conducting a task that requires more mental activity since our brain would require more rest the more we stress it.
