Waheguru Ji Ka Khalsa, Waheguru Ji Ki Fateh,
Yes, it does work. I have tried it. I was just wondering if there are any Gurmat related issues to getting sleep by listening to this kind of CD? This question might seem absurd but the very fact that I don't know, is why I ask.
The technology behind it is as follows:
How does it work?
When you sleep under normal circumstances, your brain cycles through several different stages of Delta, Theta, Alpha, and Beta sleep waves. You drift from one stage of sleep to another—from deep sleep to dreaming to wakefulness and so on. These waves are inaudible to the human ear.
Through advanced mastering technology, Power Nap piggybacks the sleep waves on audible “carrier waves” within the audible range. The result: you get the effect of the natural waves so you can sleep!
Listen to the Power Nap recording through headphones. Your brain has no sensory input other than the carrier waves playing through your ears. When you hear more than 60 seconds of a certain frequency, your brain modulates to match it. Listening to the Power Nap recording through stereo headphones for 20 minutes guides your brain through a pattern of deep sleep that would otherwise require three hours!
What happens when you listen?
You will hear pleasing waterfall-like sounds throughout the duration of your Power Nap. During the first 5 minutes or so, your brain adjusts to the sounds coming through the headphones. For the next 10 minutes, the Power Nap recording cycles your brain between deep and REM sleep periods, finally bringing your mind to a state of heightened wakefulness at the end of the recording. Then the waterfall-like sounds stop. You awaken spontaneously, feeling refreshed—as though you’ve had a long nap.
What do the waterfall sounds do?
The waterfall sounds actually don't do anything. The waterfall sounds are there so you don't have to listen to 20 minutes of "nothing" while you are Power Napping. The wavelengths that actually make Power Nap work are well below the range of human hearing, generally between 1 and 12Hz. While you are listening actively to the recording, you will begin to think you’re hearing all kinds of sounds within the white noise. This is normal. These “artifacts” are a sign that your brain has synchronized with the recording and that Power Nap is working.
I would request the opinion/views of others on this topic also, please.
Thanks
