"The NightWave Sleep Assistant is the perfect addition to a healthy sleep routine. Sleep deprivation can lead to hypertension, obesity, type 2 diabetes and cancer by weakening your immune system. Simply get comfortable in bed, turn out the lights, and NightWave leads you through an effective relaxation exercise that allows you to quickly fall asleep and get the rest you need to keep your immune system strong. I recommend it."
Dr James B. Maas"My wife has struggled for many years with difficulty falling asleep. She tends to ruminate on various issues as she tries to go to sleep at night. In recent years, it has become a bigger and bigger problem which is ironic because I’m a certified sleep doctor and run a regional sleep clinic in California.
At an annual conference for sleep medicine, I came across the NightWave Sleep Assistant and decided to purchase one for my wife with the hope that it might provide some relief for her. To our astonishment she finds NightWave so effective that she typically falls asleep within the first 7 minutes and she’s also finding it effective for falling back to sleep in the middle of the night. IMPRESSIVE! This little device is extremely simple to use and I’m now recommending it as a possible relaxation technique for patients within my sleep practice."
Dr. Barry Feldman, MD"Poor sleep causes problems for thousands of people and some even resort to sedative medication, drugs or alcohol to help them sleep better. I’ve had several of my patients use the NightWave Sleep Assistant machine and without exception, they’ve had great results. Best of all - it’s very inexpensive - and very portable."
"...this simple little inexpensive gadget actually works brilliantly well. It’s about the size of a cigarette packet, runs on a battery and just sends out a pulsing wave of blue light. You can choose the frequency of the pulsations depending on what suits you best for your own sleep pattern. After about two nights, I was dozing like a baby after about three minutes."
Dr. Gordon Cameron"The NightWave Sleep Assistant offers a viable alternative to more traditional (and expensive) sleep therapies. After having spent literally hundred of dollars on over-the-counter and prescription therapies, I trialed the NightWave and was initially skeptical. The device is safe, easy to use and most importantly, extremely effective when used as directed by the manufacturer. As a direct result of consistent use of the NightWave, I was able to stop using the oral medications entirely. I am happy to endorse this wonderful product."
Alexander R. Toll"This is a wonderful, wonderful product, a miracle product. I weighed 102 lbs. as a result of Lupus and cancer. My bones hurt and I suffer from difficulty falling asleep. Before using NightWave, I was not able to sleep at all during the night or day. But right after I got my NightWave, I was able to fall alseep every night. And unlike before, I can now relax enough to nap during the day... This is truly a gift from God."
Mrs. Lucy-Ann Greenway"I was totally amazed with the results of this product. I had been taking sleep-aid medications for five years. Within three days of using NightWave, without any pills and within three minutes I was sound asleep. I was so delighted when after two weeks I no longer needed NightWave. I have gifted this to my parents and am hearing the same thing from them."
