If youâ€™re looking for a quick pick-me-up, try taking a caffeine nap.
- 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.
- Close your eyes and relax. Even if you only doze, you’ll get what’s known as effective microsleep, or momentary lapses of wakefulness.
- 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.
