When I am tired a power nap is just the ticket.  If I take a long nap I wake up feeling drugged.  However a power nap and I wake up feeling energized.  

My quiet room is lovely.  I can look out the window and watch nature in all it's glory in the nature preserve behind my house.  The leaves gently swaying in the breeze and the sounds of nature (bird songs) lull me right to sleep.  LOVE it!
