Getting enough sleep is essential to your wellbeing and proper physical and mental health.

It also impacts the way you feel when you are awake and can affect how you think, function, learn, retain information, and interact with others.

If you are not sure how much sleep you are getting on a nightly basis, it can be a great start to invest in a sleep tracker.

A sleep tracker is worn on your body while you are asleep during the night and it will monitor your various sleep cycles to give you more insight regarding your average sleep habits.

We have compiled a list of the top five best sleep trackers, as well as rated them on a scale of one to five to help you start developing better sleep habits and feel better.

What Do Sleep Trackers Monitor?

Sleep Trackers vary depending on the type of model, but they do have some common features:

Sleep Duration

Sleep tracker devices track inactivity, so by tracking this inactivity, they can tell when you are actively sleeping, as well as when you start to wake in the morning.

Sleep Quality

Sleep trackers can tell whether your sleep is peaceful or uninterrupted and whether you are tossing and turning throughout the night.

Sleep Cycles

We will cover more of this in the next section, but sleep trackers help to track the various sleep cycles you enter throughout the night.

Environmental Factors

Some sleep trackers allow you to enter factors such as how cool or warm you keep your sleeping environment or how much light shines into your room.

Lifestyle Factors

You will typically be prompted to enter factors such as how much exercise you do, how much caffeine you consume, times of meals, and your stress levels.

Sleep Cycles

While everyone sleeps, they cycle through various sleep cycles:

1. Stage One

This cycle lasts only a few minutes and is very easy to wake up from, while you are in the beginning stages of sleep.

2. Stage Two

This cycle is still very light and easy to wake up from, but your brain waves will begin to slow.

3. Stage Three

During this cycle, you will begin to fall into a deeper sleep that is harder to wake up from.

4. Stage Four

This cycle will bring you into an even deeper sleep and your body will begin to grow, repair itself, and boost its immune system.

5. Stage Five

This cycle allows you to enter the Rapid Eye Movement (REM) phase, where your brain becomes more active and you start dreaming. Your brain will also store your long-term memories during this phase.  

The REM cycle repeats ever 90 to 110 minutes while you are sleeping, and they will slowly increase in length, depending on how long you are sleeping.

We will give our recommendations for sleep trackers that will help you monitor these cycles.

  • How Accurate Are Sleep Trackers?

    Many people may wonder how sleep trackers know the difference between someone who is sleeping and someone who is lying in bed watching television or playing on their phone.

    The best sleep tracker will track your heartrate to accurately track when you are actively sleeping.

    Obviously, when it comes to tracking your sleep cycles, sleep trackers are not going to be as accurate as obtaining a sleep study done by a professional in a lab. But they can help you gain insight into how you are sleeping each night by tracking your patterns.

    For instance, many fitness trackers provide insights such as sleep stage graphs, which will show you how long you slept and for how long you were in each sleep cycle.

    You can then take this data to analyze your sleeping environment and how it may be impacting your sleep cycles and habits.

    For instance, if you feel more lethargic when you sleep from 10:00 PM to 6:00 AM, but you feel energized when you sleep from 11:00 PM to 7:00 AM, this could be worth adjusting your sleep times (if you have the flexibility in your schedule to do so, that is.)

    In the same vein, if you notice you sleep better when your room is cooler or darker or when you stop drinking caffeine after noon, try implementing these changes into your daily routine.

    Small adjustments like this can have a huge impact on your sleep and, in turn, how you feel when you are awake.

    Having a sleep tracker can help you to pinpoint these areas of improvement and provide you with valuable data. But ultimately, it is up to you to analyze the data provided by the trackers to make educated decisions on what you will adjust.

    Why Should You Pay Attention To Sleep?

    sleeping with alarm

    Sleeping is one of the ways your body recovers at the end of each day, as well as how it repairs your heart and blood vessels.

    If you continuously deprive yourself of sleep, you could be contributing to an increased risk of kidney disease, heart disease, high blood pressure, stroke, obesity, and diabetes.

    Sleep also helps your body maintain balanced hormones, which can control your hunger cues. When you are not getting enough sleep, your ghrelin hormone increases and your leptin hormone decreases, which can make you feel hungrier than normal.

    Sleep is also important to growth and development, which is especially important in children and those who are active and exercise frequently.

    Your immune system can also suffer without proper sleep, which can cause you to get sick more frequently and remain sick longer than normal. You might find that you have trouble fighting off minor illnesses or recovering from minor injuries.

    How Much Sleep Do You Need?

    The amount of sleep you need each night varies depending on various factors, but there are general guidelines that can be followed:

    • Infants aged 4-12 months: 12-16 hours a day
    • Children aged 1-2 years: 11-14 hours a day
    • Children aged 3-5: 10-13 hours a day
    • Children aged 6-12: 9-12 hours a day
    • Teens aged 13-18 years: 8-10 hours a day
    • Adults aged 18 years and older: 7-8 hours a day

    Poor sleep habits and sleep loss will majorly impact your health, as well as impacting your mood and how you are feeling each day.

    If you are struggling to get enough sleep each night, make sure you speak to your doctor about your options and what you can do to improve this.

    Our Recommendation

    Getting the right amount of sleep for your body is crucial in so many ways and you will find that improving your sleep habits will have a domino effect on numerous other factors in your life.

    We recommend looking into purchasing a sleep tracker if you are curious about your sleep habits and want to act to take positive steps in the right direction.

    The best sleep tracker for you will be one that comfortably fits into your lifestyle, provides that data you are looking for regarding your sleep cycles and longevity, and provides guidance on what to do next.
