We have reported on the NightWave before, and it is essentially a light in a box that helps users fall asleep.
I got a chance to try it out for myself, and I got to see how it is supposed to work. NightWave has a single button controls which control a blue light which glows high and then dims to nothingness in increments that are as long as breaths. The user is supposed to time their breathing with these light phases. This stops the over-stimulation of an active mind, and relaxes the user until he or she nods off.
In all honesty, I have been working so hard lately that I haven’t had a hard time sleeping, but I tried the NightWave last night. I found that the blue light created a soft mood, and concentrating on nothing but breathing is enough to make me relaxed enough for sleep. As a rule, I usually just stop trying to sleep if I lie awake at night for too long. Next time, I’m going to turn on the NightWave.
The NightWave is powered by a single 9 Volt battery which is oddly included, and automatically shuts off to conserve power. The NightWave innards are nothing more than a 1 1/2 x 2 inch circuit board, and my only complaint is that the box case falls apart too easily. It does have a handy feature of being a blue flashlight, in case you need some light in the dark.
You should be able to get the NightWave for about $49.95 at the company site. That might sound expensive, but figure out how much it costs for sleep meds, and decide for yourself what is a better deal.
