Deep Sleep provides time for your cells to go through their repair cycles.  The immune system and repair systems of the body are many times more effective during sleep than when you are awake.  It is not enough to just sit back and relax and entertain ourselves.  We must get into the deep sleep cycles where our body is programmed to shut down and start the repair cycles.  Sleep science (yes there is such a thing) has proven that 7 ½ hours of sleep per day are optimal, anything less or more than this and the body cannot efficiently function.  Sorry folks, there is no substitute for sleep.  If you are sick, follow the sage old advice.  Go to bed and get some sleep.  This is much more effective than any drug could be.
