Just do us a favor and finish this list first. (Adapted from here: http://nyti.ms/261LLPF)
  1. Aim to sleep for 20 minutes
    Anything longer, and you risk drifting into what scientists call slow-wave sleep, a state of languid brain-wave activity considered important for consolidating memories.
  2. Set an alarm clock
    Seriously, we weren't kidding about that 20-minute thing. A slow-wave encounter is likely to leave you with what Dr. Damien Léger calls “sleep drunkenness” instead of a feeling of rejuvenation. (Léger runs a sleep-research center at a hospital in Paris.)
  3. Think of napping as a basic right, not a petty luxury
    Léger wrote a recent report arguing that all workers should be permitted naptime, an especially important respite for those working night shifts or anyone who routinely sleeps 6 or fewer hours daily. Such chronic sleep deprivation is associated with hypertension, diabetes, depression, obesity, cancer and even an increased risk of death.
  4. Find a safe space where you’re unlikely to be bothered
    If you have an unoccupied office or a dedicated rest area nearby, put it to use.
  5. Block out light with an eye mask
  6. Consider earplugs
    Absolute quiet is not a requirement for sleep, but if you are in a particularly noisy place, like a factory, you'll want to block noise out.
  7. You don’t need to lie down
    Napping can be achieved sitting upright, cheek on the desk. “Bring along a small pillow for your head,” Léger says.
  8. Prepare for peak drowsiness.
    The ideal snooze time will depend on your sleep schedule, but most daytime workers are their most drowsy in the afternoon. Léger hopes that someday, a quick slumber will re­place the post-lunch coffee. “Napping is much more powerful than caffeine,” he says, “and there are no negative side effects.”
