A few weeks ago, I wrote an essay for the Wall Street Journal that mentioned how four hours of sleep loss produces as much impairment as consuming a six-pack of beer.

Take a moment to think about the implications from this research. Across almost all professions, people will go to work today in a near-drunken state. Managers and leaders, even if they do so unintentionally, often make the problem worse by rewarding and recognizing people who stay up late and sacrifice sleep. Consider what would happen if you turn this question around and ask:

  • Do you want the person operating your car, train, bus, or airplane to have the equivalent of six beers before taking you to your destination?
  • How would you feel if the surgeon that was about to operate on you only had a few hours sleep the night before?
  • Should the person teaching your children show up for work in this state of impairment?
  • Would it be okay for your manager to show up at work after a six-pack?
  • Is it okay for your banker or accountant to essentially be drunk when making important decisions about your personal finances?

You could insert almost any profession in this equation and our answer — as parents, patients, passengers, and customers —  is a resounding “no.” Yet much of how we structure our work today is based on the flawed assumption that cutting sleep is a way to get ahead and be more effective.
