Neuroscientists know that although other brain areas can cope relatively well with too little sleep, the prefrontal cortex cannot, reports Harvard Business Review.

Previous McKinsey research has highlighted a strong correlation between leadership performance and organizational health, itself a strong predictor of a robust bottom line. In a separate study of 81 organizations and 189,000 people around the world, we found that four types of leadership behavior are most commonly associated with high-quality executive teams: operating with a strong orientation to results, solving problems effectively, seeking out different perspectives, and supporting others. What’s striking in all four cases is the proven link between sleep and effective leadership.
