The Nox smart sleep light can also act as an alarm clock.

Tech companies have a growing interest in what you do in bed. Take, for example, Sleepace. The company displayed its Nox Smart Sleep System at the Consumer Electronic Show in Las Vegas Wednesday. Nox, which will cost $280 when its released in the first quarter of this year, includes a monitor that goes under your sheets, a smart sleep light and an app that work together to ensure a better night's sleep.

Many wearables track your sleep; the Misfit Ray and Fitbit Blaze are just a couple of examples of what we've seen so far at CES 2016. But there are a growing number of products like the Nox that put hardware in bed with you so you don't have to wear anything while you sleep, such as the yet-to-be-released Samsung SleepSense and the Beddit. But Nox steps away from the slumber pack by including a multi-function light in its system.

The RestOn sleep monitor goes beneath your sheet and mattress.

The Nox system's sleep monitor, called the RestOn, is a long, microfiber band filled with sensors that you lay between the mattress and your sheet. It gathers information about your sleep patterns, heart and breathing rates and body movement and sends it to an app that recommends what you can do to get better sleep. The RestOn also sends that information to the Nox light so it can adjust for the best sleeping conditions. For example, the Nox light will turn on to wake you up once the RestOn monitor senses that you're in the lightest part of your sleep cycle. The lamp will also play soothing sounds to help you settle in and turn off when you're asleep.

The Nox light is fairly small -- about eight inches tall and four inches wide. I'd be afraid of knocking it on the floor on those morning when I'm reaching for my glasses (bad vision is a struggle, guys). But it is a promising step to incorporate lighting into your sleep routine.
