Ever notice it's easier to fall asleep when you hear the gentle chirping of crickets in the night or the low whirring of a fan in the window? You can use the power of white noise to help you relax when you're not sleeping. Take a break from your busy day and block out all the telephone rings, babbling co-workers, and computer tapping by listening to white noise. The soothing sounds of crashing beach waves, a thunderstorm, rain pouring, chimes, a clicking clock, or wind are subtly calming. They can bring you to a state of relaxation instantly. Buy CDs of tranquil sounds, or if you have an iPod Touch or iPhone, download the White Noise ($1.99) or Ambiance ($.99) applications.
