Looking for a more natural way to slip into sleep? One good side-effect-free option is music therapy. Phil Eichling, M.D., M.P.H., of the Sleep Disorders Center at the University of Arizona speculates that you can sedate yourself naturally by listening to rhythmic music with an ultra-slow beat, which may bring brainwaves into calming sync. Let these CDs help you drift off to dreamland. The expansive rhythms, hushed tones, and shimmering textures on Slow World evoke the serene feeling of lying seaside under starry skies.
