Alternate Sleep Cycles Most people only think that there is one way to sleep: Go to sleep at night for 6-8 hours, wake up in the morning, stay awake for 16-18 hours and then repeat. Actually, that is called a monophasic sleep cycle, which is only 1 of 5 major sleep cycles that have been used successfully throughout history. The other 4 are considered polyphasic sleep cycles due to the multiple number of naps they require each day. How is this possible? Histopathology Welcome to YouTube!

Sleep Sleeping is associated with a state of muscle relaxation and limited perception of environmental stimuli. The purposes and mechanisms of sleep are only partially clear and the subject of substantial ongoing research. Sleep is sometimes thought to help conserve energy, though this theory is not fully adequate as it only decreases metabolism by about 5–10%. Additionally it is observed that mammals require sleep even during the hypometabolic state of hibernation, in which circumstance it is actually a net loss of energy as the animal returns from hypothermia to euthermia in order to sleep. Humans may suffer from a number of sleep disorders. These include dyssomnias (such as; insomnia, hypersomnia, and sleep apnea) and parasomnias (such as sleepwalking and REM behavior disorder; and the circadian rhythm sleep disorders). Physiology

This natural supplement has been used for centuries in China as a memory enhancer, and was even noted by the ancient Greeks for its powerful mind-inducing effects. News and Research This is a graphic depiction of a mitochondrion which are found in great numbers in every cell. These little organelles provide cellular energy to each cell by converting foodstuffs into energy (adenosine triphosphate - commonly known as ATP). This ATP cellular energy is needed for every cell to do its job. Diabetic people typically do not properly metabolize carbohydrates well and thus are relegated to abnormally high lipid and free fatty acid uses, including triglycerides (another form of fat). Lipid metabolism produces one tenth the cellular energy as carbohydrate metabolism.
