My sister has fallen asleep to the dulcet tones of Law & Order every night for years. I myself am partial to the sound of rain at bedtime. A friend, meanwhile, swears by sleepcasts. One gadget that could work for all of us - and may work well for you too - is a Bluetooth sleep mask.

If you like to listen to something as you nod off, earbuds specially designed for sleep are certainly an option. But some people (like my sister, who has a newborn) don't want to block out all noise, which earbuds tend to do. Others just don't like the feeling of having something jammed in their ear canals all night, especially if they sleep on their side or stomach.
