Sleep induced recovery means that the brain shuts down to a low idle, and much needed repairs take place during down time - this happens between hours 4 and 7, the first few hours are for data sorting, processing and storage, and the last for forging new associations, a sort of internal learning and integration of knowledge, for which a slow awakening of certain parts of your brain are necessary. This coincides with the rise in autocrine function as the body prepares for the business of survival for another day.
Naps temporarily provide energy by shutting down drain on low supplies. Thats all. Once you pass out of the early stages of sleep into deeper sleep in a long nap, you confuse and disrupt important internal clock processes.
This is not a good practice. I can't recommend it, Premier, as neuromuscular fatigue is associated with a higher baseline of stress hormone. Normally, this is due to the accumulation of oxidative damage (wear and tear) from simple living and hard training for extended periods. Not so in the case of missed sleep. This is the disturbance of fundamental nighly repairs. Once the cells are damaged beyond a certain point (as they are, in chronic sleep deprivation), they cannot be repaired.
You have only so many cell divisions. In order for higher order creatures, like humans, to survive to have long natural lives, our bodies must be very parsimonious (hang on tightly to our cells), and so we have clever repair and defense mechanisms.
Each one of these mechanisms is disabled when we short cut our sleep. There is no real recovery and repair under these circumstances. Furthermore, sleep is the golden key for growth hormone release. Its pulsate, and its minions, IGF-1 and other anabolic hypertrophic factors, are being tuned to do their cellular best at about the time you are cutting sleep off...
In other words, it promotes accelerated aging. I can tick off other issues, like faulty blood sugar control and appetite management..need I really say more?
I think not.
