Sleep deprivation not only makes you feel miserable the next day, it’s also dangerous. When you don’t get enough z’s, your reaction time slows significantly and your emotional state turns fragile. You’re also at greater risk for diabetes and heart disease. People who suffer from sleep problems often try sleeping pills and lots of other approaches. But one of the most commonly overlooked issues is sound quality in the bedroom. Some sounds, such as snoring from a partner, are simply annoying, while irregular noises, such as a barking dog or sirens, keep your body on high alert, making restorative sleep virtually impossible. To improve the sound quality in your bedroom, consider trying one of these great “white-noise” machines…

My current favorite sound machine is the iHome Zenergy iZBT10. Based on real science, this product features nature sounds, white and pink noise and many other auditory experiences that will help you fall asleep. I recommend this to many of my patients. Where to by: iHomeAudio.com. Cost: $99.99.
