Shift workers, elite athletes, executives and students use power-naps to increase energy, concentration and performance.
A Perfect 10
The perfect power-nap should last for 10 minutes. Sleeping too little or too much will leave you feeling groggy after your nap. Exactly 10 minutes ensures you wake up refreshed and reinvigorated. Alarms can only countdown time. They are unable to know when you have entered stage 1 sleep to begin counting down from 10 minutes. Thim knows when you’ve fallen asleep – to the minute. Providing you the perfect power-nap for the first time.
Why 10 minutes?
Researchers tested four nap time spans: 5, 10, 20 and 30 minutes (and a control group that didn’t nap). They then tested participants across several benefits for three hours after the nap. Here’s a summary of the results:The 5-minute nap produced few benefits in comparison with the no-nap control. The 10-minute nap produced immediate improvements in all outcome measures (including sleep latency, subjective sleepiness, fatigue, vigor, and cognitive performance), with some of these benefits maintained for as long as 155 minutes.
How does thim do this?
The 20-minute nap was associated with improvements emerging 35 minutes after napping and lasting up to 125 minutes after napping. The 30-minute nap produced a period of impaired alertness and performance immediately after napping, indicative of sleep inertia, followed by improvements lasting up to 155 minutes after the nap.The problem is that naps are awfully hard to cut down to 10 minutes; once you get a little taste, it’s tempting to just keep sleeping. But as this and other studies indicate, longer naps are not the best naps. Snooze for just 30 minutes and you fall into sleep inertia, the feeling of grogginess and disorientation that comes with awakening from a deep sleep.
