Since the mechanical alarm clock was invented in 1876, there hasn’t been much innovation in waking up.

While the idea was the same as the rooster: loud, sudden noises ripping you from the sweet embrace of sleep, it was certainly a vast technological improvement.

However that concept is set to be changed by a slew of new gadgets. There would be easing of the manner in which people get up every day by the new technologies like sensors and lighting.

Hormone melatonin, which tells the body it’s time for sleep, is blocked by blue light, studies have shown. Features that remove blue light from smartphone screens at night to supposedly help people sleep better are being added to the smart phone by companies like Apple and Google.

That same concept is being used by sleep gadgets to wake people up. With the aim of simulating the sunrise, Aura connected alarm clock slowly floods a room with bright blue light. This is helpful for anyone without access to the actual sun.

The other major area that sleep gadgets are focused on includes gadgets like the companion sensor that slips under the mattress to track your sleep patterns and cycles.

Light, deep and REM, which is when we dream are the three sleep cycles that we go through every 90 minutes. It’s best to wake up during the light sleep cycle so that you’re less groggy and disoriented, the devices claim.

Modern sleep gadgets are also able to tracks information like how long it took you to fall asleep, if you snored, and how many breaths you took each minute. An example of this is the Beddit which is a sensor similar to Aura’s. It pairs with an app to wake you up during the lightest sleep. This technology turns sleep into a game by giving a daily score for the quality of slumber, which can be improved with a nap like many tracking products.

Apps like the Sleep Cycle can be used for simpler tracking. The movements of the person while asleep are helped to be tracked by the person’s smartphone’s accelerometer or microphone in this app.

While one has to feel comfortable wearing them at night, wearables like Fitbit also offer sleep tracking tools. Many don’t offer alarms, just suggestions based on what they’ve learned about you.

The It Bed by Sleep Number is however on the overkill end of the spectrum. It is essentially a mattress that acts like a traveling sleep lab. A sleeper’s movements and vital signs are tracked hundreds of times every second by embedded biometric sensors. to connect to the other apps and wearables piling up on your bedside table, it even has an API. The company creepily promises to “track your every day and night.”

With all this data that it collects the device finds patterns and make suggestions. For example, a person may sleep better when the temperature is below 65 degrees. A level of firmness based on the exhaustive dossier it’s collected on your life will be recommended by the adjustable bed.

It sounds like a nice, harmless way to start the day – waking up gradually to a pretty light and your favorite music, even though it can be hard science. However it is advised that one should be aware of getting too tied up in tracking and quantifying your every toss, turn, and REM state. This could lead to more anxiety.
