There is strong evidence that links sleep deprivation over time, even minor, to long term health problems. As someone who cut sleep for years (6 hours was normal in twenties and much of thirties), I can attest that at some point, it becomes difficult to operate on less sleep. If all of your coping strategies involve putting in more time (essentially at the expense of sleep), when you can no longer cut the sleep, you may be in a bind when that is no longer the corner that can be cut. Though not always, that point in time often coincides with when your parental commitments are at their peek as well, and as a parent, you probably shouldn't cut that corner. So what then... Something like the Pomodoro method helped me alot. Or just be really rich.
