Sleep And Self-Discipline

New research suggests a connection between the two:

[Y]ou have only so much mental energy during a day. From what [management professor Christopher] Barnes’s research suggests, the amount of sleep you get predicts the discipline your body can produce. Why? Sleep deprivation depletes the glucose level in your pre-frontal cortex, Barnes writes. This has consequences for your decision-making: If you don’t get enough sleep, you leave your self-control engine running on empty. If you do get enough sleep, you restore that fuel base. …

“Organizations need to give sleep more respect,” Barnes writes. “Executives and managers should keep in mind that the more they push employees to work late, come to the office early, and answer emails and calls at all hours, the more they invite unethical behavior [like cheating] to creep in.”
