NAP26 is the amazing power nap program that gives you the rest and rejuvenation of a 3-hour nap in just 26 minutes-without feeling groggy! With NAP26 you can grab a power-nap and feel the benefits of 3 hours of sleep in just 26 minutes. The soothing, pulsating sounds help you block out the world and enter a relaxed, regenerative state. Just before you enter the deep sleep cycle, a gentle voice tells me my nap is over. You wake up charged, alert, and completely refreshed. **NASA research on test pilots revealed 26-minutes as the optimum nap time, improving performance by 34% and alertness by 54%.** I am a big fan of the NAP26 power nap system. As a frequent traveler, my position takes me to different time zones and naturally I end feeling tired due to the time changes. I use NAP26 either on the plane or in my hotel room prior to meetings. It never seems to fail me! I am constantly recommending this product to my friends and associates. - Paul Brown - Airport Retail Consultant “As a firefighter, I work long hours for an extended period of time. NAP26 gives me an opportunity to catch up on lost sleep after my shift. The 26 minutes I get from NAP26 helps me fall asleep into a state of relaxation, and then I wake up to get things done before my next shift. I have recommended it to all of my buddies!” -Daren Drown, Firefighter “The NAP26 app is exactly what I needed. I sing up to 4 times on a weekend and Sunday’s I am up from 5:00am and don’t stop until 10:00pm. The 26-minute power nap keeps me going. I’ll take one around noon during my break and then I’m ready to go. I would recommend the NAP26 app to anyone and everyone!” -Jacki Taylor, Lead Singer-Sweet Chariot
