The NightWave Makes You Fall Asleep Faster With Soothing Blue Light

The NightWave is a tiny “sleep assistant” designed to relax you quickly into sleep. The soft blue light guides your breathing and focuses your mind until the next thing you know, it’s morning.

Falling asleep quickly is a challenge for many of us, myself included. (Sometimes it feels like my overactive mind keeps me awake for hours before I finally fall asleep.)

The NightWave is a smart cure for this problem. You project the light onto the ceiling or a wall and breathe in and out in sync with the light, which gradually becomes slower and slower. This does two things: It gives your active mind something to focus on (easier than doing math or counting sheep) and it gets you to relax and breathe slowly — the way our bodies naturally prepare to sleep.

I tried it for a few nights and conked out before the seven-minute session was over; I didn’t even need to try the longer 25-minute setting. My six-year-old daughter tried it with me and fell asleep before I did — a huge sleep advancement in our household.

The small device runs off a 9V battery (good for 600 uses) and has two other settings so it can be used as a nightlight or, during the day, as a relaxation device. For that latter option, you’re supposed to hold the NightWave in your hand and look at the beating light, which mimics a normal heartbeat at a relaxed 60 beats per minute. I didn’t try that option because it just seemed weird to stare at the light directly.

Using the NightWave for sleep is kind of like when you get groggy watching TV and your eyelids keep getting heavier and heavier until you just give up and go to sleep.

If you have trouble falling asleep too, you can pick it up for $79.95 directly from the Australian site, however, given the exchange rate, it’s probably a bit cheaper to pick it up from the US for $US49.95 with $US18 shipping.

  • I’m sorry but a blue light is the last thing you want as your going to sleep.

    Hence why programs such as f.lux and blue filtered lighting try to remove it before sleep. Blue light is great for the day, but it also suppresses the release of melatonin more so than other wave lengths. It is shown to completely mess with your circadian rhythm.

    Healthy natural sleep should be in a completely dark room. No light source what so ever. I’m pretty sure I’ve seen this recommendation on lifehacker also so it boggles the mind why suggest actually introducing a light source to the bedroom in the first place!

    • Your missing the Point – its for people who can’t fall asleep regardless of how dark the room is. It focuses your mind on your breathing using a subtle light and helps you fall asleep. The light turns of after a few minutes so it’s dark. As for a night light some ppl are scared of the dark (kids) and need a subtle light.

      • No, the point is that the wavelength of light selected stimulates the suppression of melatonin production. Melatonin stops you from going to sleep. Any psychological value from the device would likely be cancelled out by the actual physiological effects making the device useless.

        The fix is to remove the blue LED’s and replace them with a LED mix that provides a reddish-orange glow. This wavelength of light doesn’t suppress the release of melatonin and thus you get both the physiological and psychological value from the device.

  • LOL no. My speaker’s volume control emits a faint blue glow on the roof etc and I can tell you it does NOT help you sleep. It is so unhelpful in fact I often roll out of bed to turn it off. also LOLOLOLOL at “it focuses your mind on your breathing … blah blah blah so you can fall asleep”. Do you like naturopaths too? most BS i’ve heard all week.

    Sleeping isn’t about doing things to go to sleep when youre in bed. They will keep you up. What you need to do is to establish a good routine

    Wake up early. Exercise during the day (not 3 hours before bed). Work hard, so you know, you’re actually tired. No video games or TV after 10pm (you wont be able to sleep easily for at least an hour). Try, where possible, to keep your bedroom only for sleep and work in another room. Keep a regular routine and that’ll do it

  • If you are or suspect you maybe Bipolar it’s worth noting that there’s good scientific evidence linking bipolar people to increased sensitivity to blue light in the suppression of melatonin. It can not only disrupt sleep but make you more likely to experience bipolar episodes. It certainly did for me. If you have any trouble sleeping, stay well away from blue light for a few hours before sleep. F.lux is a really great tool if you need to use a computer, and it’s also available on jailbroken iOS, while Lux provides a similar app on Android.

    It’s worth also noting that sleep disruption is not all blue light at night can cause. In 2007 the World Health Organisation announced blue light at night “can alter sleep-activity patterns, suppress melatonin production and disregulate genes involved in tumor development,” while mice studies have shown mice on identical diets gain unhealthy weight when under blue light, while staying lighter and healthier when exposed only to natural light (blueish during the day, dark during the night). With an estimated 10% of human genes affected by melatonin, we can only begin to understand the health impacts of something like this. Citation on science: while more articles are listed at
