Best Sleep Tracker Guide

We all know that a bad nights sleep will leave you feeling groggy and tired in the morning. You wake up with a lack of energy and you just aren't ready to attack the day with your usual zest.

The number of people not getting enough sleep every night is rising as the stresses become greater and greater whether its work, family or general life related.

You may already know that you're getting optimal amounts of sleep, but wouldn't it be fascinating to be able to account for these hours. With sleep trackers now you can.

Many studies have been conducted and extensive research has been completed to explore sleeping patterns and behaviour, usually with older generation expensive equipment. Technology has progressed rapidly and now the average consumer now has the capability to monitor their own individual sleep pattern. ​

Scientists have done extensive research on sleep patterns and typically use bulky/expensive equipment to do so. However with the advent of new technologies, it is now possible for the average consumer to easily monitor their sleep patterns.​

Of course you won't be able to accurately diagnose any complex medical issues like a profession assessment would, but a sleep tracker can provide useful and interesting information about the quality of your sleep and can provide additional tips and steps you can take to improve it.​

We've hunted down the top 10 best sleep trackers to help you monitor and improve you sleeping patterns to allow you to get to sleep easier and sleep for longer.​

Alternatives to Sleep Trackers

So you can truly see how effective sleep trackers are, you must first learn about the alternatives that are available to you.

Sleep Tracking Phone Apps

The quickest and cheapest way to get started with sleep tracking is by downloading an app for your smartphone from the app store. The pricing for these apps can range from being free to a few pounds, so they are inexpensive.

​The beauty of using an app is that you don't need to purchase any additional special equipment and the phone uses its own built in accelerometer to record and measure your movement throughout the night.

​They work pretty simply, you turn the app on just before you go to sleep and position your phone under the pillow or close to you on the mattress. The phone will then take over and track all your body movements.

​However these apps do have some major flaws, with the main issue being accuracy. One example of this is that different mattresses will alter readings in a different way.

Calibration of the technology is challenging and your phone can have problems interpreting which movements are from you or your bed partner, which of course lead in inaccurate data. This is by far the worst solution and should be avoided if possible.

Sleep Clinic

The other alternative option to using a sleep tracker is to be admitted to a specialist sleep centre.

You must be refered to a sleep clinic by your doctor if they suspect that you may have a sleep order, and depending on your symptoms a sleep study may be recommended also known as a polysomnography.

Sleep clinic studies usually require you to stay one or two nights in a specially equipped room that has different types of equipment which accurately measure you sleep cycle, pattern and stages throughout the night. You will usually be observed by a medical proffesional and a whole range of information will be collated about your sleeping habits:

  • Heart Rate
  • Heart rhythm
  • Brain Waves
  • Breathing patterns and frequency
  • General muscle activity
  • Eye movement
  • Sleeping positions throughotu the night
  • Oxygen levels within your blood.

Once this is complete, the clinic will have a huge amount of data which can then be used to assess and diagnose any sleep disorders or issues that you may be suffering from.

Of course a small sleep tracker is not going to be as effective as a sleep study but it can still provide you with some very important information that can lead you to getting a better nights sleep.​

It must be remembered that it can be difficult to get referred to a sleep clinic and if you decide to do it privately it can be extremely costly so using a sleep tracker is great initial alternative.​

Non Wearable Sleep Monitor Devices

Whilst the majority of sleep trackers are wrist devices, there is an alternative. There are now a number of non wearable devices that stay in the bedroom that can monitor your sleep.

These are ideal for people that are interested in gathering more detailed and accurate data. The devices is either tucked into you mattress or sits on the top for you to lie on.

The device detects and records three different types of body vibrations: chest movement for breathing, big body movements and Cardioballistic effect. A Cardioballistic effect is tiny recoil within the entire body when the heart beats.​

This technology is still very new to the market so they haven't yet undergone widespread rigorous independent testing. However it's very promising for what the future holds as technology continues to advance at breakneck speed.

How Do Sleep Trackers Work?

The majority of sleep trackers use Actigraphy technology. Actigraphy uses non invasive methods using Accerlerometres; a device that has the capability to record a users movement and position. 

So in simple terms, if there is a certain amount of the movement the device concludes that the user is awake, and when there is little to no movement the device concludes that the wearer is asleep.

Actigraphy is actually used in sleep clinics by health professionals, however they test many different things so it plays a smaller part in the overall results compared to a sleep tracker.

In some ways a home sleep tracker may be more effective and accurate than a sleep clinic. If you are admitted into a sleep clinic you will be sleeping on an uncomfortable hospital bed surrounded by several machines and have electrodes placed on your head. These factors can lead to you finding it even harder to fall asleep.

If you were to use Actigraphy in the comfort of you own home by wearing a device for several weeks, it may give you a truer and more accurate insight compared to ​a couple of nights in an unfamiliar sleep clinic.

How Accurate are Sleep Trackers?

​There have been many debates about how accurate sleep trackers that use Actigraphy are in comparison to polysomnography that is used by sleep clinics.

In 2011 research was published by Hakim and Martin which studied the accuracy, usefulness and effectiveness of wrist Actigraphy for sleep assessment.

It was also compared to to the following other types sleep behaviour assessment.

  • Daily sleep diaries
  • Clinical lab Polysomnography
  • Clinical interviews
  • Sleep Qustionnaires
  • Videosomnography in children

It was concluded that wrist Actigraphy is significantly more effective for assessing sleep patters in natural environments out side of a clinical setting. 

The duo also stated that wrist Actigraphy is accurate when it comes to reporting on information such as:​

  • Total sleep time
  • Sleep percentage
  • How long it takes to wake

In addition they also stated that the main accuracy issue with sleep trackers is that they can wrongly conclude that being awake and motionless is you being asleep. This can be inaccurate for people with severe stage insomnia who lie completely still and do not move about.

It's clear to see that wrist Actigraphy does have some clear drawbacks, but it is definitely useful and manufacturers are constantly making improvements to increase their accuracy.

To solve this issue, many sleep trackers allow you to signal when you are trying to go to sleep rather than just sitting still relaxing. Whilst other trackers also let you manually retrospectively correct any mistakes that you think the​ tracker has made.
