What actually happens when your mind is completely blank?

According to researchers, the phenomenon of "mind blanking" often appears after activities that require high concentration such as studying for exams, in a state of sleep deprivation or after high-intensity exercise.

A new scientific study has discovered the phenomenon of "mental blankness," a special mental state in which a person is completely devoid of any thoughts or awareness, distinct from ordinary states of distraction or daydreaming.

According to researchers, this phenomenon often occurs after activities requiring high concentration, such as studying for exams, during periods of sleep deprivation, or after high-intensity exercise. Notably, this state tends to occur when the brain is either too highly or too low in terms of stimulation.

Experiments on healthy volunteers showed that when in this state, the brain exhibits signs of "deactivation" with an increase in slow brainwaves similar to those experienced during sleep.

The test subjects' heart rate and pupil size both decreased, and parts of their brains appeared to enter a state of localized sleep.

Particularly dangerous, a person in this state is completely unaware of any stimuli from their surroundings. This can have serious consequences if it occurs in situations requiring alertness, such as driving.

The study also indicated that "mind blanking" is one of the core symptoms of generalized anxiety disorder and is linked to several serious health problems such as stroke, seizures, traumatic brain injury, and Kleine-Levin syndrome—a rare sleep disorder that often affects adolescent males.

Dr. Thomas Andrillon from the Paris Brain Institute, one of the lead authors of the study, suggests that if we can better understand the mechanisms of this phenomenon and control it, it could become a useful method for coping with anxiety and negative emotions.
