Wearable technology for tracking sleep: What is the best sleep- tracking bracelet?

Rapid advancement happening in the field of wearable technology is revolutionizing the healthcare industry. More and more people are using wearable devices that could track various markers of their health. One such important marker is sleep. If you want to know what is the best sleep-tracking bracelet, please read till the end. I will start with what exactly sleep trackers are, why you need them, and finally, list some popular sleep trackers. You will then be able to compare and choose the one you like.

What are sleep-tracking devices?

Devices that track our bodily functions when we are asleep are known as sleep-tracking devices. There are different types of sleep-tracking devices that are out there on the market, starting from sleep-tracking bracelets that you can wear on your finger or wrist to bedside sleep trackers that you can keep on a bedside table or even devices that you put under your mattress or bed sheet, also known as Bed sensors. These days, there are even watches that records sleep patterns.

Sleep trackers generally track things such as the body movement of a person while he or she is asleep. Another important thing is that most modern trackers monitor heart rate. It also tracks the following

Duration of Sleep: These devices can track your duration of sleep. They do so by tracking the time one is inactive in bed.

Quality of sleep: Quality of sleep is very important along with duration. Sleep tracking devices detect the interruption to one’s sleep and let the user know when he or she is waking up during sleep.

Different phases of sleep:  Also known as sleep cycles such as REM sleep. However, many experts say that sleep trackers cannot track sleep stages correctly. For that, a proper sleep test needs to be performed in a hospital or laboratory setting.

Some sleep trackers even record environmental factors.  They might track the temperature of your room or the amount of light your room gets.

Why do we need to track our sleep?

So what is sleep? Well, it is a physiological phenomenon that is necessary for our body. Sleep rejuvenates the body and is necessary for the health and well-being of every individual. It repairs our DNA. Lack of sleep could lead to various health issues like high blood pressure, heart disease, and stroke. It’s even linked to obesity and diabetes. 

Sometimes, even if someone thinks he or she is having a good night’s sleep, in reality, might be suffering from conditions like sleep apnea which if untreated, could become fatal.

You  definitely need to track your sleep if 

  • During sleep at night, you frequently wake up.
  • Feel too sleepy during daytime
  • Looking forward to optimizing performance and improving your fitness.

I am going to list six different sleep trackers below which are widely purchased

Fitbit Sense


Fitbit Sense is a Smartwatch that also tracks your sleep in detail. I think it’s the best Fitbit is offering right now. It has an ECG sensor that tracks the electrical signals of your heart and lets you know if you have any signs of atrial fibrillation. It also has a stress monitoring function which is really useful. It helps you in measuring your stress level and keeping it under control. Fitbit Sense estimates sleep stages by detecting movement and heart rate patterns.

Fitbit Sense can also measure your Oxygen saturation level during the night, thus helping you to check if you have any signs of Sleep Apnea.

Skin temperature can also be measured with this device.

If you are conscious about your health and want to put an eye on your sleep and heart health, this is the best device for you.


  • Contains ECG
  • Good battery life
  • The band looks good and is very comfortable to wear.
  • You will be able to make virtual friends with whom you could do challenges.


  • Needs to sign up for premium support to use the ECG facility after six months trial period is over.
  • To use the music function, you need to sign up for paid services like Spotify, Pandora, or Deezer.
  • The Heart rate monitor is not perfect.

Garmin  Venu 2
