Since then I’ve been emailed about this topic as well, probably because I’ve written previously about becoming an early riser. Polyphasic sleep involves taking multiple short sleep periods throughout the day instead of getting all your sleep in one long chunk. A popular form of polyphasic sleep, the Uberman sleep schedule, suggests that you sleep 20-30 minutes six times per day, with equally spaced naps every 4 hours around the clock.
This means you’re only sleeping 2-3 hours per day. I’d previously heard of polyphasic sleep, but until now I hadn’t come across practical schedules that people seem to be reporting interesting results with. Under this sleep schedule, your sleep times might be at 2am, 6am, 10am, 2pm, 6pm, and 10pm. And each time you’d sleep for only 20-30 minutes. How can this sleep schedule work? It was interesting to read some of the posts from people who’ve tried this sleep cycle. Sleep well! Alternative Sleep Cycles: You Don’t Really Need 6-8 Hours!
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? How is this healthy? Well the most important of every sleep cycle is the Stage 4 REM (Rapid Eye Movement) sleep, which has been shown to provide the benefits of sleep to the brain above all other stages of sleep.
This way, you still get the benefits of 8 hours of sleep without wasting all of the time it takes to get to REM cycles, resulting in a much more efficient sleep cycle. Uberman Cycle: 20 to 30 minute naps every 4 hours, resulting in 6 naps each day. Everyman Cycle: One longer “core” nap that is supplemented with several 20-30 minute naps. Dymaxion Cycle: Zinc–air battery. Zinc–air hearing aid batteries During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate (Zn(OH)2− 4), releasing electrons to travel to the cathode. The zincate decays into zinc oxide and water returns to the electrolyte. The water and hydroxyl from the anode are recycled at the cathode, so the water is not consumed. The reactions produce a theoretical 1.65 volts, but this is reduced to 1.35–1.4 V in available cells.
Zinc–air batteries have some properties of fuel cells as well as batteries: the zinc is the fuel, the reaction rate can be controlled by varying the air flow, and oxidized zinc/electrolyte paste can be replaced with fresh paste. Possible future applications of this battery include its deployment as an electric vehicle battery and as a utility-scale energy storage system.
