The effect of stress on the brain
From the Harvard Business Review:
What toll does it take, over time, if you get too little sleep; skip breakfast or settle for something unhealthy; struggle with a relentlessly challenging commute; attend meeting after meeting with no breaks in between; pump yourself up through the day with multiple cups of coffee or sugary snacks; deal with hundreds of emails that accumulate in your inbox; remain at your desk for lunch if you eat lunch at all; push through fatigue in the afternoon; head home at night feeling exhausted, but continue to check email through the evening; work on the weekends; and limit your vacations to no more than a week or two, if you vacation at all?
. . . .
"Allostatic load" is a term coined by the neuroscientist Bruce McEwen that refers to the physiological consequences — most especially on the brain — of chronic exposure to relentless demand. When fight-or-flight hormones circulate in our body for too long, keeping our arousal high, they become toxic — not just physically, but also emotionally and mentally.
The most immediate problem with the fight-or-flight state is that our pre-frontal cortex begins to shut down. We become reactive rather than reflective. We lose precisely what we need most in these complex times: the capacity to think analytically and imaginatively; to embrace nuance and paradox rather than choosing up sides; and to take a long-term perspective rather than making the most expedient choice.
It's not good for us . . . .
