Best Sleep Trackers For Optimal Energy Reviewed

Few things inhibit human consciousness and capability like getting inadequate rest. When you don’t rest there is a myriad of things that start going haywire in your body. On a purely cognitive level, some reports list the level of impairment of going without a full night’s rest as being similar to the level of impairment of someone who is over the legal limit of alcohol. Tracking one’s rest can be done with sleep trackers.

Considering just how dangerous it is for someone to be operating a vehicle or finding their way around public while being impaired from alcohol, imagine how inadequate rest impairs your day-to-day functions.

When you don’t get enough rest, aside from the immediate consequences of having compromised reflexes, judgment, and motor skills, you are also putting yourself at a higher risk for chronic health conditions. Among these conditions are obesity, heart disease, and diabetes. While we rest, our body generates the hormones it needs to help regulate things like appetite, metabolism, and the processing of glucose. When you disrupt this cycle, all of these processes get thrown out of whack, and your health, both long-term and short-term, suffers as a consequence.

For athletes, adequate rest is vital. For the average person, rest is a time for the body to perform nightly maintenance. For people who are pushing their bodies to the limit during the day, however, rest takes on an extra dimension. It is the time when the body repairs and tends to stretched-out and damaged muscle tissue, building it up and making it stronger. If you skimp on the rest and don’t give your body time to recover, eventually your body will break down and give out. It’s like taking your car offroading without doing any preventive maintenance or checkups; you’re just asking for trouble.

When you are able to get enough rest, the benefits can be amazing. You’re sharper, clearer, and more on top of your game. Being able to bring your absolute best to the ring, court, or mat necessitates that you are getting quality REM time every night. To be able to detect your rest patterns and nightly cycles, it there are many great products out there that can help you gain access to this knowledge.


10 Best Sleep Trackers



1. Withings / Nokia

Nokia is perhaps most infamously known for their seemingly indestructible cell phones. That same durable spirit has carried forward through the years. This product tracks heart rate continuously both during rest and while waking up, keeping detailed reports. It also reports on your rest metrics, keeping records of such data as your light and deep rest cycles, how often your rest is interrupted, and the depth and regularity of your REM and other cycles.

25 Day Battery Life
While you're charing your item, you're not using it. Why purchase something if you have to take it off every day just to juice it up? Each time it's off your wrist, it's not doing what you paid for. This product, though, only needs to be charged every twenty-five days, making sure you get the most out of your purchase.

Smart Notifications
This is one the most advanced rest monitors on our list, being a fully bonafide smartwatch in addition to its other functions. This product can be synced with your smartphone to give you all the notifications you'd normally see on your phone in one convenient device you can wear wherever you go.

Cost and Value
This is the second-most-expensive product on our list. If you're not looking to spend a lot of money and are just looking for a simple rest monitor that doesn't have a lot of extra features, you'll want to go elsewhere. However, if you want a high-end product, or are in the market for a smartwatch and want one with an advanced rest-monitoring feature, this could very well be your dream product.

Real-time Tracking

When you’re not resting well, you’re not fighting well. In order to get the most out of your training, you have to ensure that you’re getting adequate recovery time as well. A fighter that is getting the most out of their nighttime respite is a fighter that is in tip-top shape inside the ring. The benefits aren’t only physical, by means of better circulation, denser muscle mass, and less lactic acid buildup. The benefits are also mental and psychological: you’re more alert, more acute, and quicker to respond. Overall, getting a good night’s sleep is one of the best gifts you could give yourself.



Criteria for Evaluating the Best Sleep Trackers


  • Smartwatches: One of the most common and ubiquitous items in today’s world of wearable biometrics is the smartwatch. These devices sync up to your phone and allow you to track all kinds of activity, not just your metrics during the night. These products are typically used as workout assistants, though they are versatile in their capability. These devices not only allow you to access your biometrics in real-time but also, by virtue of their connection to your phone, allow you to view your notifications without having to carry your phone around with you.
  • Wearable devices: Wearable devices are devices that need to be placed on your body in some fashion or other while you rest during the night to be able to access your body’s data. These devices are typically put in one of three places: (1) around the wrist, (2) as a ring around your thumb, or (3) as a necklace around the neck. These devices need to be flush against the skin to be able to track heart rate, among other things.
  • Bed monitors: Bed monitors are the only variety of rest monitor that does not need to be worn. Rather, sensors are placed underneath the mattress. From underneath the mattress they sense patterns in your movement throughout the night, as well as taking readings on the different cycles your unconscious brain is cycling through. These items are usually freestanding and connected to the sensors either remotely or via wires.


  • Cycles: There are three main cycles the unconscious mind goes through throughout the night. Light, deep, and REM sleep. REM stands for Rapid Eye Movement and refers to the state in which dreams occur. It is normal to cycle through these different phases multiple times throughout the night, and each serves an important purpose in the body’s recovery process from the trials of the day before, and preparation for the day tomorrow.
  • Blood oxygen: The amount and level of oxygen in your blood is a huge indicator of how restful and useful for nighttime will be. Detectors that monitor for blood oxygen also tend to measure snoring. Many have built-in vibration alarms to warn you if you begin to snore.
  • Heart rate: This is perhaps the most basic metric that can be gathered. It is also universal to all rest monitors. No matter the make, model, brand, or type, this is one data point that you can be sure will be recorded.


  • View on-device: Some products, especially smartwatches, have display screens built right in that allow you to read your metrics in real-time. These screens are usually LED and are backlit for ease of viewing. The only downfall of this method, though, is that it is difficult to view a detailed and long report on such a small screen.
  • View externally: Some products do not have a built-in interface and require you to access the data through another method, by USB cables, for example. The method is either an app that you download with the purchase of your rest monitor, or in an interface that can be viewed on tablets, computers, and smartphones. The plus side of this method is that it is easier to view large amounts of data on a larger screen.



Frequently Asked Questions

Q: How does this device measure my biometrics?

A:  Rest monitoring devices use a variety of methods to track your biometrics. Some wearable units, such as smartwatches, use LEDs built into the underside of the watch to reflect light on the skin in order to detect changes in blood flow. Some use something called actigraphy–or recording movement through a device to detect your current amount of motion. Others use an array of sensors placed underneath the mattress to detect levels of movement.

Q: What do I do if the software stops working?

A: Contact the manufacturer immediately. They will either help you with troubleshooting the problem, rebooting your product or will send you a replacement product. Some products glitch or crash; the particular defects you may experience are usually unique to the individual model of rest monitor you purchase.

Q: How do I know which kind I should buy?

A: This depends largely on your individual needs and budget. If the idea of wearing a product to bed annoys you, you’ll want to purchase a model that is freestanding and doesn’t need to be in physical contact with you. If you’re looking for a device that can do more than just measure your nighttime biometrics, you may want to consider purchasing a smartwatch.

Q: Can I download my data into an excel spreadsheet?

A: This will vary largely from device to device. Some only display your data on pre-formed charts. Others will allow you to fully export all of your data into a variety of templates and apps. As a rule, higher-end models generally have more capabilities for exporting data; these, however, also come with an increased price tag.

Q: Is this device compatible with Mac? (Or Windows?)

A: You will need to check the individual product specifications to determine its compatibility. Generally, most products have cross-platform and cross-OS compatibility. Companies want to maximize profits, and thus it’s in their best interest to make their products as widely usable as possible.

Q: Am I able to sync my rest monitor with my phone?

A: It will determine the variety of product you purchase. If you are using a smartwatch as a rest monitor, then the answer is yes. Other kinds of products may also sync with your phone via an interactive app. Others, though, need to be accessed through a computer or in-device screen.
