Effect of polyphasic sleep on life Style
Elshatiti, Ghada Suliman (2018-03-19)
sleep cycle lasts about 90 minutes and during that time we move through five stages of sleep. The first four stages make up our nonrapid eye movement (NREM) sleep, and the fifth stage is when rapid eye movement (REM) sleep occurs. Polyphasic sleep is a sleep trend wherein sleep takes place in fairly brief naps throughout a 24- hour time frame
