Sleeping 4hrs/day

  1. A few friends, especially in California (where trading hours and pre markets are early!) share how they've practiced to work with minimal sleep.

    I was wondering if anyone is successfully pursuing this.

    I'm thinking on attempting to do this, but work with a computer in bed while using minimal energy, except for my head and maybe eyes.
     
  2. Read up on the sleeping habits of Thomas Edision & Ben Franklin for some enlightenment.
     
  3. Thanks
     
  4. "If you sleep more often, you can get by on a lot less sleep"

    Not sure where I saw that or read it, but it sure seems to be true. But only 4 hours a day? I couldn't do it. Some people need more sleep than others, and I am definitely one of those who needs more.
     
  5. If you sleep 8 hours per day and live to be 75 years old, you slept for 25 years.

    Cut down on the sleep and you get free years.
     
  6. I heard it was genetic. Most people need to get 8 hours in order to function. Maybe 6 hours if you train yourself. But 4 or less, you need to be genetically endowed. Probably something to do with the amount of REM sleep one needs.
     
  7. But if you don't get enough sleep, you are asleep on your feet for the other 50. I don't want to live that life. Everyone is different.
     
  8. human beings are extremely adaptable creatures....and for that matter the most underrated.

    having said that, the only way to know if your body can adapt is to gradually reduce your sleep.

    if you normally need 8 hours of sleep, start with 7 hours for around a month and reduce by 1 hour each subsequent month.....your body will be your guide.

    brief afternoon naps can be extremely helpful.
     
  9. Trading takes immense mental focus

    Why do you only want to sleep 4 hours a day ?
     
  10. Big mistake. I night traded for the better part of 5 years.

    Male testosterone production begins to decline in the early 30's. Testosterone is primarily triggered through the HPTA (hypothalamus-pituitary-testicular-axis) via hormonal sequence GnRH > LH > Testosterone.

    The obvious trick is to maximize GnRH, which, incidentally, is released most at night, during deep REM sleep.

    You fuck up sleep, and you'll fuck up your testosterone, which will have a terrible effect on your libido, erections, weight, muscle mass and tone, thought clarity, mood and well-being. I know this through personal experience and it's well established in the scientific literature.
     
  11. Lack of sleep is associated with high BP, diabetes, weight gain and premature death. :eek:

    Dying ain't much of a livin'
     
  12. "I heard it was genetic. Most people need to get 8 hours in order to function. Maybe 6 hours if you train yourself. But 4 or less, you need to be genetically endowed. Probably something to do with the amount of REM sleep one needs."

    If I was genetically endowed I would likely sleep less also.


    Sorry, but that was just a big fat pitch
     
  13. Sleeping is when humans are at the most vulnerable. Clearly mother nature says we need to spend 1/3 of the day in this state for a reason.
     
  14. Take plenty of naps, and i agree, your body will adjust, but at the same time its hard on the body. But do whatever you have to do to succeed. Its not like you will be doing it for the rest of your life. And try to get a workout in there when you can too.
     
  15. I've read a bit about this, it's called polyphasic sleeping, where you take multiple naps throughout the day. Rumor has it famous people like Da Vinci did it. The most extreme is called the uberman/superman sleep schedule where all your sleep are short naps as opposed to one main longer sleep cycle along with one or more naps.

    The research on death and health risks with lack of sleep are focused on just one sleep cycle per day. Not much research is done on polyphasic. Here's some research from a UC medical sleep clinic which shows 7hrs on average is ideal for monophasic:

    Here's some interesting info on polyphasic sleeping:

  16. Did that for a couple of years, when I was in my early twenties; working 3 minimum wage jobs to pay off some bills.

    It was definitely very hard on the body, and I lost a bunch of hair :( And guess what, they didn't grow back :eek:

    It definitely got rid of the bills real quick, though :D

  17. In Western civilization before the Industrial Revolution, segmented sleep was the dominant form of human slumber since time immemorial, according to A. Roger Ekirch, a historian at Virginia Tech. Over the course of nearly two decades of research, Ekirch discovered extensive evidence of this sleep pattern in a wide variety of documents, dating from the ancient world until the nineteenth century. Typically, individuals slept in two discrete phases, bridged by an intervening period of wakefulness of up to an hour or more. Peasant couples, who were often too tired after field labor to do much more than eat and go to sleep, awakened later to have sex.[1] People also used this time to pray and reflect,[2] and to interpret dreams, which were more vivid at that hour than upon waking in the morning. This was also a favorite time for scholars and poets to write uninterrupted, whereas still others visited neighbors and engaged in petty crime.[3]

  18. Virginia Tech...there is the first problem

  19. Be aware of how your attitude might change with lack of sleep.

    If I get less than 7-8 hours sleep a couple days in a row I can be a very grumpy bastard and I get the blues easily.
     
  20. I'm like this as well if I only sleep once. But I found if I take a nap, I feel great (maybe even better) with 5-6 hours of sleep.
     
  21. "Karla Allebrandt and her team from the Ludwig Maximilians University of Munich discovered that people who had two copies of one common variant of ABCC9 slept for “significantly shorter” periods than people with two copies of another version."
