**OUR CYCLES OF SLEEP! <br /> <br />The Neurologists often speak, of five different <br />stages of sleep! <br />Sleep generally commences in a light state, - <br />When the brain triggers high amplitude <br />‘theta waves’! <br />And after some five to ten minutes, rapid bursts <br />of ‘sleep spindles’ flow, - <br />Which lasts for some twenty minutes or so! <br />Next we float on to a transitional phase, - <br />When the brain triggers ‘delta waves’, - <br />And we float between a light and deep sleep <br />phase! <br />Soon we get submerged into ‘delta sleep’, - <br />With Non-Rapid Eye Movements, - going <br />into deep sleep! <br />And with some people it has been seen, bed- <br />wetting, or sleepwalking, - <br />Often occurs during the end of this phase! <br />Finally comes the REM* stage when we dream, - <br />When increased respiration and brain activities <br />are seen! <br />But despite our active mind, our voluntary <br />muscles remain paralyzed! <br />This REM stage is said to increase, with the <br />progress of our night’s sleep! <br />And when the night grows dark and deep, - <br />These stages of our cycles of sleep, - <br />Breaks away from these sequential stages ! <br />When after the fourth stage, comes the third <br />and second phases, - <br />Repeating themselves till the day breaks! <br />When finally after our REM dreaming state, - <br />We once more begin to gradually awake! <br /> -Raj Nandy <br /> 10 Apr 09 <br />(*REM= Rapid Eye Movement: dreaming phase! <br /> Based on various articles.Prelude to my next <br /> poem about sleepwalking!)<br /><br />RAJ NANDY<br /><br />http://www.poemhunter.com/poem/our-cycles-of-sleep/
