There are many methods and products available for helping individuals with sleep problems or insomnia issues to fall asleep. These range from techniques, such as focused breathing and relaxation, to prescription medication, such as Ambien sleep medicine, to novel uses of technology, such as sound and light machines and the use of white noise.

It is this last category - the white noise machines - that is going to be the focus in this article. Why? Because while millions of people deal with sleep problems every night, most of them are familiar with everything on this list above with the exception of using a white noise machine. So let us see if that gap in knowledge can be filled in just a little bit today!

When the goal is to assist with sleep, a sleep machine can be used to block out external sounds and mental stimuli. This is accomplished through the use of constant, repetitive white noise, which the mind locks onto and uses as a kind of barrier between the brain and the outside world. Additionally, in a very real sense, having a Homedics white noise unit close to your bed stand at night literally makes it a sound that is close by, and thus blocks out other sounds from a further a distance.

When the brain gets habituated to a repetitive sound, the conscious mind pushes this sound into the back ground. In other words, a repetitive ceases to be heard in contrast to a new sound. A simple example of this in everyday life is how people rarely hear their clock ticking or how a person might not notice that the air conditioning had been running and making a loud constant sound of air blowing until the AC turns off. In the absence of the sound, the mind recognizes it had been there easier than during the presence of the sound.
