From Wired’s How To wiki:

Scientists say that a successful midday nap depends on two things: timing and (no kidding) caffeine consumption. Experiments performed at Loughborough University in the UK showed that the sleep-deprived need only a cup of coffee and 15 minutes of shut-eye to feel amazingly refreshed.

1. Right before you crash, down a cup of java. The caffeine has to travel through your gastro-intestinal tract, giving you time to nap before it kicks in.2. Close your eyes and relax. Even if you only doze, you’ll get what’s known as effective microsleep, or momentary lapses of wakefulness.

3. Limit your nap to 15 minutes. A half hour can lead to sleep inertia, or the spinning down of the brain’s prefrontal cortex, which handles functions like judgment. This gray matter can take 30 minutes to reboot.

Probably the biggest issue with workplace meetings is their length. Almost always, meetings take longer than is necessary. This is particularly true for those daily keep-us-up-to-date meetings.

Instead of sitting at a traditional conference table, we took the chairs out of the room and ran meetings while standing on our feet. Well, the length of the meetings DRASTICALLY dropped, because people didn’t want to stand for long. Meetings went from 30-60 minutes to roughly 1/2 of that while still delivering meaty content. Neat, huh?
