Ever find yourself fighting off those midafternoon yawns and droopy eyelids?
Don’t blame yourself for having a big lunch or a lack of willpower.
Sleepiness is actually caused by our natural sleep-wake rhythm controlled by our internal body clock.
Activley taking a power nap during the day makes perfect physiological sense.

But what is it about power naps that actually helps us recover?
The secret lies in the deep non-REM sleep that comes at the onset of sleep.

In non-REM sleep, we reach Stage 2, a light sleep level, about 20 minutes after first falling asleep.
It’s durring stage 2 sleep that the accumulated cache memory is cleared from our brains.
Brain fatigue is washed away resulting in a positive effect on the body.
