Sleep deprivation is not a badge of honor

Lack of sleep hurts workforce productivity ...

"Forgoing sleep is like borrowing from a loan shark. Sure you get that extra hours right now to cover for your overly-optimistic estimation, but at what price? The shark will be back and if you can’t pay, he’ll break your creativity, morale, and good-mannered nature as virtue twigs.

Now we all borrow occasionally and that’s okay if you fully understand the consequences and don’t make it a habit. I did that the other night. We pushed an update to OpenBar, which had me working until 1:30 AM. That wouldn’t have been so bad if it wasn’t because I got woken up at 5 AM to help deal with an issue that arose. But the costs the following day were typical, numerable, and expensive:

* Stubbornness: When I’m really tired, it always seems easier to plow down whatever bad path I happen to be on instead of reconsidering the route. The finish line is a constant mirage and I’ll be walking in the desert for much longer than was ever a good idea.

* Lack of creativity: What separates programmers who are 10x more effective than the norm is not that they write 10x as many lines of code. It’s that they use their creativity to solve the problem with 1/10th of the effort. The creativity to come up with those 1/10th solutions drops drastically when I’m tired.
* Diminished morale: When my brain isn’t firing on all cylinders, it loves to feed on less demanding tasks. Like reading my RSS feeds for the 5th time today or reading yet another article about stuff that doesn’t matter. My motivation to attack the problems of real importance is not nearly up to par.
* Irritability: If you encounter someone who’s acting like an ass, there’s a good chance they’re suffering from sleep deprivation. Your ability to remain patient and tolerant is severely impacted when you’re tired. I know I’m at my worst when sleep deprived.

These are just some of the costs you incur when not getting enough sleep. None of them are desirable. Yet somehow it seems that the tech industry has developed a masochistic sense of honor about sleep deprivation. At times it sounds like bragging rights. People trying to top each other. For what? To seem so important, so in need, so desired that humanity requires you to sacrifice? Chances are you’re not that special, not that needed, and the job at hand not that urgent."    (Continued via 37 Signals)    [Ergonomics Resources]
