The How & Why of Sleep is a field of medicine that is being increasingly emphasized.
A study published in the Biological Psychiatry September 15, 2008 reports "sleep disturbance is associated with inflammation and related disorders including cardiovascular disease, arthritis and diabetes mellitus."
Sleep has a direct relationship to physical and mental health
& healthy sleep is comprised of 90 minute sleep cycles. Each 90 minute cycle consisting of the 5 stages of sleep.
Inadequate sleep increases the risk for heart disease as well as autoimmune disorders (i.e. rheumatoid arthritis).
Lost sleep causes the brain to stop producing cells & thus lower intelligence. "The suppression of adult neurogenesis may underlie some of the cognitive deficits associated with prolonged sleep deprivation.", Dr Elizabeth Gould
Narcotic / prescription sleep meds are detrimental to proper sleep.
are required for personal optimization
University of Chicago Researchers found that the first stage of age-related deterioration of sleep quality in men occurs between the ages of 25 and 45.
Factors involved in poor quality sleep include:
Obesity results in medical conditions like sleep apnea
Prostate enlargement / continence
Alcohol & Caffeine consumption
Too little exposure to sunlight upsets our sleep cycle
Digestive issues such as 'heartburn'.
The discomfort of Arthritis effects sleep position.
Stressors: family issues. financial issues, or social issues
Aging effects our sleep. We wake up more often through the night and sleep less deeply.
As we age we enter into deep REM & Delta sleep less. Deep REM & Delta sleep is where our body has 'time' to heal & recover'.
Proper sleep is very important for health. GABA is a neuro-transmitter involved in REM Sleep / dream state. Enjoy vivid dreams with GABA (When was the last time you had a vivid dream?)
Brain scans during sleep have allowed researchers to actually see brain activity patterns during the stages of sleep.
The 5 Stages of Sleep.
There are 5 stages of sleep that SHOULD cycle through 5 or 6 times throughout the night. Proper restful sleep will cycle through these 5 stages of sleep every 90 minutes throughout the night.
Proper sleep equipment is essential .. you should spend 1/3 your life sleeping.. show sleep the respect it deserves
University of Chicago Researchers found that the first stage of age-related deterioration of sleep quality in men occurs between the ages of 25 and 45
They're sleeping as long as younger men, but they're spending less time in restorative deep sleep, the scientists write in the Journal of the American Medical Association
The scientists studied 149 healthy men ages 16 to 83.
Sleeping less deeply doesn't just mean that thirty something men might be more likely to be awakened by street noise outside the window. (This study did not find that more frequent awakenings during the night accompanied declines in deep sleep.)
It also means that their bodies are secreting less growth hormone, the study found. In recent years, studies in the elderly have linked growth hormone deficiency to increased obesity, loss of muscle mass and reduced exercise capacity.
Another University of Chicago study in 1999 by Dr. Eve Cauter limited a test group of men to only four hours of sleep per night for 2 weeks.
The subjects showed decreased levels of Leptin and increased levels of Cortisol.
There was a measurable loss in production of the positive hormone Leptin & an increase in the negative hormone Cortisol.
The reduced sleep resulted in loss of the rejuvenation benefits of Delta & REM sleep.
Non-REM sleep rejuvenates the parts of the body damaged by metabolism and free radicals,
REM sleep repairs the repair center that rejuvenates the body during Delta Sleep..
