“When we do not sleep enough or when we are tired or exhausted, for example after a day of work in an open office, it is our reflecting brain that is tired and it is our cognitive resources that are depleted. This is even visible in brain scans where we can see that the part of the brain that moderates the emotional brain is too sleepy to do its job. [321] This not only has a negative impact on the quality of our thinking, but since our reflecting brain then has difficulties regulating our emotional reflex brain our emotions become more primitive and exaggerated, we become over-reactive, over-emotional towards negative stimuli and are much less able to see negative things in their proper context. It also leads to a decrease in emotional intelligence in general and less socially intelligent behavior, due to a lessening of our intrapersonal awareness, interpersonal skills, emotion management, empathy and moral judgment. [322] A well-researched aspect is that with a lack of sleep we have greater difficulties appraising emotional facial expressions, [323] which of course reduces our ability to react in an emotionally and socially intelligent way.”
