Change Leadership
In an interesting TED talk, Russell Foster explain why it’s a myth that we all need 8 hours sleep a night. He also claims that people who boast about getting up early in the morning are simply ‘smug’!
Foster explains the neuroscience behind why sleep deprivation can also lead to being overweight with poor problem solving skills and lack of judgement.
Think again, if like former British PM Margaret Thatcher, you believe that sleep is for wimps!
Ever considered that the amount of sleep you get is a key factor in whether you lead and retain your staff?
Researchers tell us that sleep is critical for our children’s capacity to learn. If they don’t get enough sleep, their ability to make new connections and their ability to concentrate is impaired.
Typical daily sleep requirements for children by age are:
Infants (3 to 11 months): 14-15 hours
High performing brains, especially the pre-frontal cortex areas (PFC), require heaps of energy in the form of glucose. The PFC is responsible for our executive functioning like planning, decision-making, analysis, comparisons and behaviour control i.e. complex cognitive activities.
Just like children, if we are haven’t had enough sleep then our bodies prioritise the available energy just to keep us physically functioning. That means our brains, especially the PFC, lag behind in the race for glucose.
Result: tired brains find it hard to come up with new or the best answers.
So, for example, we may end up repeating what we have done before even if we know we should find a new approach. We find it hard to focus, we procrastinate or we hastily make decisions that we should have slept on!
Dan Ariely at Duke University (check out his TED talks) wondered if decisions made in negative emotional circumstances in the past influenced future actions when the original emotion was no longer present. He did some experiments and concluded that they did.
Reason: when we make decisions, we tap into the memories of decisions we made in the past that can be linked in some way to the present situation. That’s easier for our brain than having to come up with new neural connections (a new decision).
Now, negative memories (and their associated decisions) will always come to mind first because our amygdala is always on guard to protect us. They will, as Ariely puts it become part of the blueprint’ for future actions.
And it’s when we use this blueprint and respond inappropriately, that’s what I call The Almond Effect®.
If we are tired our PFC is too exhausted to reflect back on the emotional circumstances in which the original decision was made and consider whether the decision is still the correct one in the fresh situation.
We are then likely to make the same poor decision even though we may not be feeling the same negative emotions we felt when the original decision was made!
I wonder if that’s why office feuds and politics, silo battles, home arguments, even wars, go on for so long – long after the original cause has been defused. We just haven’t stopped to challenge the pattern in our brain and so keep repeating decisions and behaviours because that’s the way it’s always been.’
So, for most of us lack of sleep means snap decisions, procrastination, repeating bad decisions, inability to concentrate and bad moods. And because we are tired we eat the junk food our bodies crave for an instant sugar (glucose) hit. We are too weary to do any exercise and so the exhaustion cycle continues – just adding to the load on our bodies and the depletion of energy.
Do your people love working for you when you are like that? Are you a good leader? Do they feel engaged’? They might put up with it for a few days, a few weeks, even longer but in the end, they’ll walk away and find someone who is easier to work with.
I’m not going to tell you to go to bed earlier, take a break, get some exercise, eat proper food, cut down on the alcohol – you can work that out yourself.
But at the very least, acknowledge when lack of sleep is impacting the way you lead. Consider whether, if you were in your people’s shoes, you are providing the kind of leadership that will encourage your best employees to perform and stay?
If the answer is no and lack of sleep has something to do with it, then maybe you should let your kids put you to bed, read you a bedtime story and kiss you goodnight!
