Without a king in my head. The activity of the prefrontal system depends on many factors: stress, lack of sleep, mental and physical overload, and burnout weaken it. Poor overall health, hormonal imbalances, lack of sunlight or a poor environment can all reduce the strength of the prefrontal cortex. In addition to the general decrease in mental productivity, something even worse occurs: inhibitory control over subcortical centers, including the amygdala, nucleus accumbens, etc., is weakened. Disinhibition leads to the phenomenon of “mind wandering,” which, against the backdrop of stress and fatigue, takes on a negative coloration. After all, in a state of stress, the significance of negative factors is higher and they automatically attract attention.
