Criteria Used for Evaluation

Features

If you are going to invest in a nice fitness tracker, you want one with the features which will meet your needs. Since we are talking about sleep monitoring, that is the first feature you will want to look for. Find a tracker which monitors your sleep patterns during the hours that you are normally asleep. It should keep track of your deep sleep, lighter sleep, and wake times. Then the information should upload into an app where you can see it at one place and can analyze it to see what the patterns are. From there you will be able to make changes to help yourself get a better rest which always makes a huge difference in your health.

Check out all the varieties of faces and bands on fitness trackers. Find the colors you like and a face which is big enough to read easily without being too bulky, especially if you have a thin wrist. Make sure it syncs to your specific smartphone brand or to your computer.

It is also handy if you have a tracker which will monitor your incoming messages so you will not lose track of important messages. Most of them show you who is calling, let you briefly see a text message, or give you incoming social media messages.

Ease of Use

You want a fitness tracker which is easy to use. If you are using it to monitor your sleep, you need to be able to wear it to bed. That means you need a watch which is not going to be bulky to scratch you during the night. It also needs to not light up and wake you up whenever you brush against it while moving around. Having a vibrating alarm is handy too so you can be woken up easily and gently without waking up other people in the room.

The display should be easy to read and it should be easy to page through the information you are looking for either with a touch screen or with easy to understand buttons. It is nice if the display lights up and it should be big enough you can read it easily.

Having a tracker which is compatible with Bluetooth helps with ease of use so it is easier to connect with apps. Speaking of which, the app should be easy to navigate so you can get to the information you need and easily understand what you are reading because they have it set up clearly.

Most of the trackers have notification alerts which help you easily see who is calling you so you know if it is important enough to interrupt your workout and answer. Most of them also let you see text messages as they go across the screen. Some of them also help you keep track of social media messages like Facebook, Instagram, Twitter, and others.

Durability

Since this is something you will probably be wearing to 24/7 you will want a fitness tracker which is durable. The band should be durable yet flexible and made of a material which will not irritate your skin. The clasp should be sturdy and hold it on your wrist without slipping or scratching.

The face of the watch would be durable enough to resist scratches while you are wearing it during your everyday life. It is also handy if your watch is water resistant so you do not have to worry about sweating or running in the rain. It should also be dust resistant so dust cannot get into the cracks and mess up the functions.

Being durable means having a strong battery life and also the connection to recharge it. It should be water resistant. It would be handy if you could wear it in the pool or even in the shower, but at the very least it should stand up to your body sweat.

Comfort

You will be wearing this fitness watch for most of the day and night, you need one which is comfortable. Take a look at the band and the material it is made out of. It should be soft and flexible while being durable. You should be able to wear it snug against your skin without it irritating or causing your arm to sweat too much.

The clasp should keep the watch snug and attached while at the same time being at a good angle where it is not going to irritate you in your daily life by snagging on your clothes or anything else. The face of the watch should be big enough for you to be able to see comfortably so you can read it on the go, but it should not be so bulky on your arm that it gets in the way.

You need a tracker which has a strong battery as well so you can keep your monitoring on track. The battery should last for a long time, usually at least a week or so. When it is time to charge, it should be easy to do and quickly. If it plugs into a USB port, the plugs should be sturdy so they do not break off when you use them.

Effectiveness

You want a fitness tracker which is going to be effective at helping you to track the quality of your sleep. It should keep track of your heart rate during the day and then while you are sleeping as well, and be able to tell when you are in deep sleep or light sleep. This information should be recorded and uploaded to an app where it can be analyzed you can recognize patterns. From there you should be able to look at the information and use it to make changes in your habits so you can get better rest and improve your health.

Also to be effective, the tracker needs to be able to keep accurate data. It should give you the correct time and when it monitors your heart rate and blood pressure as well as steps and other fitness information, those numbers should be accurate so they will be useful for you.

It is also nice if you have a watch which will help you keep track of phone calls, messages and calendar events so you do not have to worry about such things while you are working out. To be more effective, it helps if the tracker is scratch resistant, dust resistant and water resistant so it does not interfere with whatever you are doing throughout the day.

Learn The Sleep Stages So The Information Is Useful

It is important to know a little about the sleep stages so you can get the most out of your monitoring. When you are sleeping at night you typically go through multiple sleep cycles which last about 90 minutes each. You have stages of light sleep and deep sleep through the night. The deep sleep periods are usually longer earlier in the night. The REM sleep periods feature vivid dreams and are usually longer as the night goes on.

Wearing A Monitor Gives You A More Natural Read

If the watch will help you monitor your sleep at home, then you can get a real sense of your true sleep health. You are at home in your own environment so you can make a good decision about how to optimize your sleep. The long term tracking will help as well.

Other Factors to Consider

Band

You want a band which is soft and comfortable so you are content with wearing it all day. It can be made of rubber material, plastic, or leather. The band should fit snugly without any extra length hanging which is going to get caught on things.

It is also nice to have a band which is water resistant so it will not be affected by sweat or rain. There are fitness trackers you can even swim or dive in, however, we do recommend that no matter how resistant they are, you should take it off in the shower. It is better for your skin if you take it off so you will not have water under the band. You want your wrist to stay clean and dry.

Frequently Asked Questions

q: How does a sleep monitor work?

a:

The main way that your sleep cycle watch measures your sleep activity is through actigraphy. Actigraphy uses movement, as measured through an accelerometer to measure your sleep. This is based on the idea that the period when you are awake you are moving more than when you are asleep.

​Even though polysomnography is the most accurate measure of sleep activity, it has its problems. It involves hooking a person to a whole lot of measuring machines before they fall asleep. This, in itself, is bound to ensure that the person does not have a normal sleep; it is far too invasive. As a result, actigraphy has been used by researchers as a less invasive method of recording sleep activity for decades.

q: How Accurate Are Sleep Trackers?

a:

Sleeptracker watches provide relatively little data when compared to the gold standard for measuring the quality of sleep – polysomnography. This is a collection of different physiological measures that can be used to define and characterize sleep. Patients stay overnight for these sophisticated sleep studies which require a slew of equipment, from muscle monitors to EKG machines.

Fitness monitors use accelerometers to measure actigraphy. Rather than actually measuring sleep, they are measuring your sleep approximately by measuring your movement. Since the purpose is to make estimates on deep sleep versus light sleep, the best sleep monitor uses a unique algorithm that measures the level of movement your body does in different amounts during the night.

So, how accurate is actigraphy as a method of measuring sleep? A study was conducted in 2011 by Martin and Hakim which looked at that very question. Their conclusion was as follows:

Actigraphy should never be used as any type of substitute for using things like sleep diaries, clinical interviews, or overnight sleep studies, it does provide useful information concerning how you sleep in your natural environment which could clue you in on things which may need additional monitoring. They are not able to record sleep latency, which is the time it takes to fall asleep. Neither are they very good at telling how long you are awake in the middle of the night or your total sleep time relative to the time you are in bed.

Sleep monitor devices do encourage you to pay more attention to your sleep habits. This is a very good thing. A lack of sleep can affect mood, ability to concentrate and stay tuned in to our day. Fitness band sleeps trackers not only help us to get our steps in. They also help us to get our zzz’s in.

q: How long does the battery last?

a:

This answer will vary a lot depending on the tracker you have. It will depend on how many features it has run on it. You can usually count on 5-7 days of life before you need to charge it. If it a battery inside the unit which you have to replace, most of the time they last about a year.

q: What is the most accurate type of sleep monitoring?

a:

Polysomnography is the most accurate way to measure sleep, but it is also very expensive and impractical for most of us. These sleep trackers fill the gap. Tracking your sleep actigraphy (body-movement analysis) which is what they use is up to 90% as effective as the expensive polysomnography.

q: Why is good sleep important?

a:

Sleep is a major key to good health. It helps your body relax and rest. You wake up full of energy and have good concentration. It also helps in keeping you from getting sick. It is not just the amount, but the quality of sleep that matters.
