How Does Sleeplessness Affect Our Minds and Body?

Lack of sleep isn’t good for you, in fact, it is harmful. It affects your body. 

Dodie is a retired RN with close to 40 years of experience.


“We certainly know that a lack of sleep will actually prevent your brain from being able to initially make new memories, so it’s almost as though without sleep the memory inbox of the brain shuts down and you can’t commit new experiences to memory,” said sleep expert Matthew Walker, professor of neuroscience and psychology at the University of California and author of the book Why We Sleep

“After just one night of four to five hours of sleep, there is a 70 percent reduction in critical anticancer-fighting immune cells called natural killer cells,” he wrote.

“And that’s the reason that we know that short sleep duration predicts your risk for developing numerous forms of cancer.”

  1. Few add on points

    Lack of D wave sleep leads to metabolic issues. This is because you need 2 hours per night D wave to regenerate hormones.

    One of the common but not discussed reasons for lack of D wave sleep is airway restriction this is usually genetic

    Signs of airway restrictions:

    1. Light sleep
    2. Sleep anpnia
    3. Panic dreams
    4. Waking up and difficulty falling back to sleep
    5. Other breathing issues
    6. Mouth jaw formation issues
    7. Clutching teeth
    8. Grinding teeth
    Plus others issues including organ/ blood pressure heart ect…

    Metabolic system energy supply comes from ( in order of importance)

    1. Oxygen
    2. Sugar
    3. Carbs
    4. Fat

    If oxygen is short what will you crave? 🙂 self medication

    Interesting related fact. Before you were born you had gills to breath. To breath you would clutch your mouth and push fluid to increase oxygen

    When you grind and clutch teeth you are subcontiously attempting to increase your oxygen intake

    I’m told that many adult onset diabetes is misdiagnosed oxygen issue as people will self medicate with increase in sugar and carbs

    • Very interesting. Over 20 years ago, I had surgery to remove uvula, route out sinus cavities, etc. due to severe apnea. It didn’t take.
      Today, I’m 64 lbs. lighter and use a CPAP. The first night I used it, the results were incredible. There was enormous clarity in my thinking, brain functions, and big improvement physically.
      I either have forgot😁, or never heard of the D waves, but will research more about it.
      Thanks again.

  2. Sinus
    Under bite
    Tongue tied ( various degrees)
    Orthodontic work some dental work can all impact airway

    Swallowing are paramount to living a healthy life

    Know your dentist and orthodontist! Very few are oral biology trained
