Sleep Hacking, Part II
AddThis Social Bookmark Button

Animal research suggests that the behavioral consequences of sleep deprivation may be the result of changes in the actual function of brain neurotransmitters. Thus if you keep it up and "sleep hack" you can theoretically change your brain chemistry. By the way, these studies are quite strange. They are adapted from the old "flower pot technique" which is where you put an upside down flowerpot on a tank of water where there is just enough room for the mouse to sit. As he get sleepy he will fall into the water and climb back up so as to not drown- I think this may be where Mark Burnett came up with his first ideas for the reality show <"Survivor".

We are still learning the role of sleep and memory in humans. Thus sleep deprivation, and even partial deprivation can have big effects on someone's memory ("Dude where's my car??"). By sleep-hacking one may be selectively depriving themselves of sleep. You see, sleep occurs in some cyclic patterns which can be altered with deprivation. As an example we see people go into sleep in stage 1, then more to 2, 3, 4, back to 2, and on into REM sleep. Thus to get to the deep good stuff you basically need to go through the cycle. When sleeping for 45 min - 1 hour you don't get a chance to get there. However by doing this it creates a "sleep pressure" or homeostatic drive for sleep. That in and of itself may not be a bad thing as we often use this as a technique called "sleep restriction" for people with insomnia asking them to stay up late and get up early ( restricting their sleep) to build this pressure to help them sleep.

However a second force ( not to be confused with "The Force"-I am an old Star Wars geek) is called the circadian pacemaker. Here we see that the body based on certain cues called zeitgabers (not some weird german delicacy), like light, social cues and exercise, tell the body when to do things like eat or sleep. Thus by napping every 2.5 hours or so you are going against this system for example if you are trying to sleep at 12 noon.

In addition, the entire argument changes as you age. Napping at noon for kids may be just fine while it shouldn't be for a 21-year old ( unless it is Sunday and you have had a big night on the town).

Sleep Hacking
AddThis Social Bookmark Button

Sleep hacking aka polyphasic sleep is an interesting but hardly new topic in the sleep world. We see that, in actuality, everyone at several times in their lives are sleep-hackers. Meaning that they sleep for short periods of time, almost napping throughout the day as opposed to having a longer, continuous bout of sleep. When are these times? Infancy and old age. As infants we move in and out of "naps" quite frequently and the same thing occurs as older adults when there is little else to do.

Sleep hacking appears to be taken from the notion that there were several very famous people who would sleep for short periods of time, create wonderful and miraculous concepts or items ( DeVinci, Einstein, etc). There is now a small movement to "hack" sleep or try to only nap for a certain period of time, then get up and continue the day in the hopes of only getting the most needed sleep in these small bouts and being incredibly productive when awake.

In truth when doing this all that you are doing is causing sleep deprivation to your system. Awhile back a blogger conducted a sleep hack experiment, logging his results. His was a very interesting experiment with somewhat expected results. He consistently had a difficult time waking up at the right time, he felt as though he is a little sick, and is not as productive as he is normally. I really like that he is honest in his experiment and that he has told at least one person to seek medical advice before trying this program. In all likelihood the people who in the past have done this are what sleep researchers call "short sleepers". People who just do not need more than about 2-4 hours at a time.

In my next blog post I will explain why sleep hacking may work for some short sleepers but be fighting the forces of Mother Nature for the others.

Doctor of ZZZZZZZ's

I just wanted to say hi and introduce myself to the blogsphere out there. My name is Dr. Mike Breus, I have a PhD in Clinical Psychology and I am board certified in Clinical Sleep Disorders.

I have been on the WebMD message boards for the past 6 years and man, have I answered some doozies! The great thing about my topic is that everyone sleeps which is why it is a perfect topic for the blogging world.

Now I will admit that I am new to blogging, but I think it reminds me of a cocktail party conversation. Usually my wife tells me that I can't tell people what I do because as soon as I do they hit me with question after question. She usually rolls her eyes and finds a comfy seat on the couch, cause she knows I'm going to be yammering away about sleep.

I'm looking forward to yammering away here on the blog and I hope you all get something out of it -- maybe even a good night's sleep!

p.s. -- There will be no dream analysis here, if I hear one more story about being naked with a 3rd grade teacher...
