The idea of learning while we sleep has been around for almost a hundred years. It turns out that getting information while we sleep doesn’t appear to be a terribly successful way of learning. But all is not lost.
If we learn something and sleep on it, we do in fact process information and thus can retain and categorize information more effectively.
Now, researchers have determined that if a sound is experienced along with something that we want to remember, hearing that sound again helped recall the original experience. In addition, if that sound is heard while we sleep, it seems to cement the memory of the experience even more than simply re-hearing the sound in a waking state.
In other words, if you see a picture of a cow, and you hear a ticking clock, just hearing that ticking clock the next day will probably help you remember the cow. However, it you hear that same ticking clock sound while you’re sleeping, your ability to remember the picture of the cow will be improved greatly when you hear the ticking.
So, it appears that sonic branding, like I discussed last week, can even have a more powerful impact if those sounds can be heard while people sleep. This could create a powerful way to remember experiences if say, audio brands were interspersed in relaxing music that played while we slept.
It could also be used to design classroom experiences. Key points in a lecture could have musical notes or sounds as an accompaniment. Those sounds could be given to students in MP3 form so they can listen to those sounds when they study and sleep. They could replay those sounds later to help with recall.
I could see it used as well for training purposes. People do a certain task to certain musical tones. When they’re first learning, they can listen to those tones as they sleep.
What if operating rooms had musical sequences to help nurses, techs and surgeons remember pre-operative prepping procedures?
How could you see this research being used?

This recently published blurb in Wired gives three reasons why sleeping late may be better than going to bed early and rising early.
1. You may need more sleep than you think (i.e. You don’t sleep nearly enough)
2. Night Owls are more creative.
3. Rising early occurs during peak Cortisol levels so you may feel tension upon waking early.
When I checked the study responsible for point number 3, another interesting thing became obvious and it may account for point Number 2.
Cortisol is also at its lowest between 10pm and 1am. If stress hormone is low, creativity may be higher during these times.
FORMULA A: Less stress hormone (Cortisol)=more relaxed=more creative.
If I extrapolate a Creativity Curve based upon the cortisol curve we see the following:
Possible Creativity vs. Cortisol Curve (michael plishka, 2008; red curve courtesy of http://www.phoqus.com)
Is the above relationship absolute? Probably not. The folks over at the Benson-Henry Institute for Mind-Body Medicine have shown that changes in stress (i.e the relaxation response) can produce “aha” moments. And, as I mentioned here, stress is essential to performance. So there are most likely some micro-stress trends within the larger trends that can help or hinder creativity.
Nevertheless, studies are starting to show that increased cortisol levels that don’t decline during the day may induce clinical depression. So…
FORMULA B: Less sleep=greater stress=clinical depression=less sleep=greater stress…
It’s a downward spiral that will not help with creative endeavors.
What do we take away from this all?
1. We need sleep.
2. We have to be careful not to stay up too late. If we overshoot our lowest cortisol levels, we may have trouble falling asleep. Since cortisol rises quickly in the AM, we don’t want to be stuck getting stressed when we should be recouping. Rising cortisol levels also might maker it more difficult to stay asleep or get good quality sleep. That means waking up feeling sleep deprived and that puts us into FORMULA B above….bad news.
3. We need to learn to relax better- take time to meditate/pray/relax/play so that we minimize the effects of stress when we’re awake.
What are your thoughts on creativity and sleep?
