Almost everybody is trying their best to lead the healthiest life possible. What most people don’t realize is that sleeping well is as important as eating healthy food and exercising. The lack of sleep can lead to various health problems. It increases your chance of illness, heart-related diseases; it affects your mood, sex drive, and overall health. It can even impact your memory! People who sleep less also crave for junk food and sugar, so that affects health as well.
People who came to this realization have been paying particular attention to sleeping well. That’s why sleep trackers have been such a huge trend these last few years. They are great if you want to find out more about your nightly slumber. If you are struggling with your sleeping patterns, or you want to learn more about your shut-eye, getting a sleep tracker may be a good option for you.
Sleep trackers can monitor your nocturnal movement, heart, and breathing rate, and some of them can even record snoring. They can measure the total time you spent asleep, if you had any interruptions, how many times you have woken up during the night, how long it took you to fall asleep, and even track the different stages of sleep.
Sleep trackers collect all this data and then give you detailed analytics and graphs about all of these things. What’s great is that most of them have coaching tips for better sleep, so not only you will learn about your sleeping habits, but you’ll also get useful advice on how to improve these habits.
They can also monitor ambient noise, light, and temperature, all of which play a significant role in helping you fall asleep faster.
Continue reading to learn more about different types of sleep trackers, how they work, and how to pick the best one for you. We have also selected, tested and reviewed some of the best sleep trackers on the market for you.
Wearable vs. Non-Wearable
There are two types of sleep trackers – the wearable ones and the ones that are contactless. If you choose the wearable option, you can pick between sleep tracker rings and bracelets. They are great for active people because not only they give you information about your sleep, but they also have great fitness trackers that can count the steps you make, your calorie intake and consumption, and other things that can improve your health.
Contactless sleep trackers usually consist of tracks of fabrics embedded with movement sensors and a small processor that collects the data. They are specially designed for tracking your sleep, so you don’t get all the other fitness perks of a wearable sleep tracker. Because of that, they come at a lower price, so you can save a few dollars by buying the non-wearable option.
Both wearable and contactless models connect to a sleep tracker app that gives you all kind of information about your sleep. Sleep tracking apps can do all sorts of things, depending on the app, but generally, they can track the total time you were asleep during the night, how many times you’ve woken up, and some can even monitor your heart rate, breathing rate and snoring. What’s amazing is that they can also figure out how much time you’ve spent in different stages of sleep, so they can tell you when you were in the light, deep and even in the REM stage. Most of them also have a smart alarm option, and they can calculate when you are in the light stages of sleep and wake you up. That is very important because waking up in the deep stages of sleep can make you feel groggy, disoriented and more likely to hit that snooze button a few times. And it’s so easy to use this option; if you need to wake up at 6 am, you just put in the desired timeframe when you want to wake up, e.g., 5.30 am to 6 am, and the app calculates when you enter the light stages of sleep during that time frame and wakes you up (for example at 5.47 am). Standard alarms can often be too loud and can make your awakening the worst part of your day, but that isn’t the case with these alarms. They tend to rely on vibrations and soft melodies, so waking up is going to be a much more pleasant experience.
How do They Work?
Wearable sleep trackers rely on measuring tools called actigraphy. The principle behind this is pretty simple; a device called accelerometer measures movement, and the lack of movement corresponds with sleep time. It also measures heart rate and combines those two parameters to see if you are really sleeping or just resting in your bed.
Non-wearable models are a bit different, but with the same idea. They operate on infrared technology and strips of materials with sensors under or on top of your mattress, and then they measure movement, heart rate, as well as other things and describe your sleeping patterns. They can also measure respiration, which is an excellent indicator of sleep quality as well.
The logic behind this idea is pretty solid, but the main question is how well sleep trackers work and how accurate they are.
How Accurate are Sleep Trackers?
It is crucial to know how accurate sleep trackers are. If they are just some fancy gadgets with no real accuracy, they won’t be of much use.
Scientists have done their part and did some research on wrist actigraphy, and how effective it is. The results are pretty promising.
A study done in 2011, by Martin and Hakim shed some light on how accurate wrist actigraphy is. They looked at how this technique compares to sleep diaries, clinical interviews, laboratory polysomnography and other methods the doctors use to grade sleep quality. They concluded that this method is good at obtaining information about sleep in natural surroundings, rather than the laboratory. They also found that it can pretty accurately give information about the total sleep time, sleep percentage and how long after sleep the waking occurs.
Another study done in 2013, by Marino and a group of researchers tried to determine how good the actigraphy is compared to polysomnography. Polysomnography is a technique used by doctors to assess the quality of sleep and detect sleep disorders. It is done in a laboratory, and the patients are carefully examined and observed for a number of nights, while machines measure different things including heart rate, breathing rate, and brain waves. Polysomnography is considered a gold standard when it comes to sleep, but it has its problems. It’s done in the lab surroundings, and it’s invasive, so it’s kind of hard to imagine you can sleep naturally with needles stuck in your skin.
The study reported very similar results to a 2011 research, and they conclude that the actigraphy can be very useful in determining the sleep time and wakefulness after sleep.
Even though scientists agree that actigraphy can accurately detect when people are asleep, they are a bit more skeptical whether they can determine the time spent in individual stages of sleep.
Although the commercially available wearable sleep trackers still need to go through rigorous testing, we can see that the science behind them works and that they can be beneficial. Contactless ones haven’t been put to such a degree of research, but the manufacturers are claiming that their accuracy is very high. They go as far as saying that those are the best sleep trackers available on the market.
Customer reviews also give us some insight into how well they work. Most common complaints about sleep trackers are that they sometimes can’t distinguish laying still and sleeping. People with insomnia would often lay motionless, and trackers could mistake it for being asleep. Sometimes, they can even think that you are sleeping while you’re in bed, reading a book or watching a show. However, the new models are pretty advanced, and those mistakes are not frequent.
How to Pick the Best Sleep Tracker that Fits Your Needs?
There are just so many sleep trackers on the market, so how to decide which one is the best for you? Even though the principle behind them is the same; there are still many differences between them. You need to look at several things if you want to pick the perfect one for yourself. Here are some things that you should keep in mind before buying a sleep tracker:
- The first thing that you need to consider is whether you want a wearable or a contactless model. If you are easily irritated by wearing something on your wrist, maybe you should consider getting the contactless one. Wearable trackers are not an ideal solution for people who don’t like to wear jewelry. If you are one of them, it is the best idea to get the non-wearable model. The manufacturers always try to use the best and most comfortable materials possible, but even the most comfortable materials can irritate this group of people after some time.
- Wearable sleep trackers are so much more than just that. They are fitness trackers as well, so they are the best choice for active people. They can give you great insight into how much you exercise, how well you eat and how all of that corresponds with your sleep. They are amazing if you want to know more about your overall health, besides the sleep part.
- Non-wearable trackers can only track you while you are in bed, and they usually need to be plugged into a wall. Also, some of them need to be turned on every night before you go to bed, which can be a minor inconvenience, especially for those who don’t want to have to remember this every night. If you are forgetful, you should avoid trackers that need to be set every night.
- What is your budget? The price can vary depending on the features and the design, and it can range from $50 to $300. Usually, the amount of money corresponds to the number of functions you are getting, but that’s not always the case. So be sure to check what are you getting for your money.
- Check the app! The interface of the app is something you want to look at, as you’ll be looking at it every day. There’ll be graphs, analytics, sleep tips, and reminders. Check for manufacturers videos, take a look at app store screenshots, and decide which one suits you best.
- If you want a wearable tracker, check out what size and color you want. It’s something you’ll wear every day so make sure it suits your style.
- See if you are getting a warranty with your sleep tracker, as most of them come with a warranty for one or two years.
- Lastly, check the reviews as they can help you make the right decision!
If you still can’t decide for yourself, let us show you some of our favorites. We have tested and reviewed some of the best sleep trackers available on the market. Here are our top picks in both wearable and non-wearable category.
