How Does Sleep Tracking On Fitness Trackers Work?

How Does Sleep Tracking On Fitness Trackers Work?The simple answer to this is comprised of two components: Heart rate monitoring and an accelerometer.

Heart rate monitoring is a vital feature that fitness trackers have and it tracks your heart rate throughout the day and during the various kinds of activities you do.

They can, with statistics, tell which of your heart rates indicate sleep, which indicate being still, which indicate mild activity, and which indicate vigorous activity. Using this information, a sleep tracker can tell when you’re asleep or not.

Some trackers even come with automatic sports recognition which can easily tell when you’re doing different activities like walking, running, cycling, dancing, playing sports, or swimming.

An accelerometer is a sensor that measures the acceleration of your moment throughout the day, to indicate different activity levels. They can also indicate the number of steps you took and even the steps you’ve climbed if the tracker has an altimeter.

Both of heart rate monitor and accelerometer combined together work to give you sleep monitoring that is as accurate as possible.

How does your fitness tracker know when you’re asleep?

A question that asks itself, however, is whether sleep tracking feature in those fitness trackers is reliable and how accurate the information is.

Well, for a regular everyday consumer, the answer would be that they give you a good idea and a general background on the quality of your sleep. Although it is not a hundred percent accurate.

However, if you’re a person with a medical condition or a sleep disorder, these fitness trackers may not be the most accurate devices to use. This applies especially to the tracking of sleep stages which is something some of the fitness trackers’ manufacturers claim that their trackers do.

To monitor the stages of your sleep, experts and professionals use brain waves and eye movements to give an accurate estimation of how much time you spend in each stage of sleep, broken down into light, deep, and REM sleep.

This is the most accurate way and anything else wouldn’t give you reliable information that you can use for treatment or improvement with your sleeping disorder.

Compared with the polysomnography –a scientific evaluation of a person’s sleep-, the fitness trackers were easy to trick due to their great dependence on the accelerometer.

So the bottom line is, if you’re using the tracker to give you a general idea on the quality of your sleep, then there are no worries and you’ll get a good background on how well you sleep.

Is an HDR monitor worth it

Are High Dynamic Range (HDR) gaming monitors worth buying? It is a common known fact that technology is a forever evolving theory thus it never stops at one point and it keeps generating new and certainly improved gadgets or features that make our lives more easier.

Is An HDR Monitor Worth It?

Is an HDR monitor worth itLet us start with the HDR technology history, it first appeared in the photography department; its main aim was to display images with lighting that looks as realistic as possible.

You might wonder how would that work; HDR functions by boosting up the contrast between the light and dark areas throughout the time of enhancing the displayed colors of an image to make it seem closer to how your eyes would see its colors in real life.

The outcome will be the results of a life-like images that have vivid quality in details as well as the colors.

But as for the gaming department; HDR will offer a great refinement in your gameplay experience, possibly in some games better than some others. You will be the recipient of a display with a much more brighter image with higher contrast and rather highly colored quality with vibrant details in the shadows and highlights.

In consideration of the foregoing, there are some concerns when it comes to HDR and gaming; there is an absence of support and content when it comes to some games as there are not many PC games that support HDR, as well as the occurrence of some issues that appear in the process of toggling HDR mode on windows, you will need to work your way out by fidgeting with a lot of settings and drivers in order for it to work properly.

To receive the best experience possible, you should invest in an HDR gaming monitor that support either FreeSync 2 or G-Sync HDR in order to minimize the issues mentioned above.

In the market, you will be faced with five HDR standards that each one has a different formula which might end up confusing the user more and more.

The first standard is the Dolby Vision, it is the high colored representative as it uses dynamic metadata to improve color for each frame, unlike other standards which only provide static metadata.

Moving on to HDR10 and HDR10+; HDR10 is the most popular, it used by companies like Sony and Microsoft, it is easier to handle for both manufacturers and users. As for the HDR10+, it is an advanced level if the HDR10, it has an improved dynamic application of metadata.

The fourth standard is a bit different, the HLG (Hybrid Log Gamma) is best made for programmers and manufacturers which makes it the ultimate gem for the developers world. Last standard is the Advanced HDR, this standard is highly used for live productions and broadcasts along with many media extensions.

Final Words: Should You Buy an HDR Monitor for Gaming?

To polish this off, here is our final thoughts; we believe that maybe getting an HDR monitor for gaming might not be the greatest idea because there are some games that do not support the monitors’ content which will create a gap in the specifications.

Among other things, most gaming monitors do not offer the optimal HDR viewing experience seeing that they lack the proper hardware for it.

If you choose an HDR monitor for gaming, it will certainly be a major upgrade for better graphics, with that said note that HDR is not supported by TN technology panels.

You might need to consider what is more important to you in this case, a monitor with high-end graphic or a monitor that possesses a 1ms response time for a faster pixel display.

How Do Fitness Trackers Track Calories Burned

When purchasing a fitness tracker that has a calorie burned indicator feature, you must ask yourself how would a fitness tracker calculate the amount of burned calories? If we are going to be real, the thought of it being just a smartwatch wrapped around your hand must have occurred to you, how does it function?

How Your Fitness Tracker Tracks Calories Burn?

How Do Fitness Trackers Track Calories BurnedLet us start from general knowledge first, our BMR short for “basal metabolic rate” is simply the rate at which you burn calories while you are resting just to maintain vital body functions such as: breathing, heartbeat, and brain activity.

Usually your BMR is estimated for at least half of the calories you burn in a day and it can be accounted based on the physical data you entered when purchase a fitness tracker then start creating a health profile which includes information such as: gender, age, height, and weight.

Based on your BMR calories, fitness trackers calculate the burned calories based on your heart rate, it is most likely the best and most reliable way of calculating.

So let’s say If you were very stressed during that meeting, and your heart rate was elevated, the chances of your calories burning abilities will be much higher than usual.

Moreover, a fitness tracker provides an in-depth estimation by taking into account not only the BMR as mentioned above, but also adds on the activities recorded by your tracker, in addition to any activities you might log manually.

The longer you wear your tracker the more accurate your resting rate, and the more accurate your resting rate is, the more accurate the calorie burn estimation will be.

There was a study made a while ago done by some doctors along with an experiment that was based on people testing out fitness trackers by wearing them then later debate any conflictions made between the results of the fitness trackers as devices and the results the doctor produced using professional and medical devices; the study assured how fitness trackers have very low errors in their estimation and their accuracy level is good, and how usually the device work by using the BMR method.

The BMR count in your  fitness tracker will reset itself every night at midnight thus you will be able to start a new day with a fresh negative counter that will begin counting immediately even if you have just gotten out of bed, and it is all thanks to how BMR burned calories work.

Although we should note that any fitness tracker can very much count your heart rates precisely but you can not rely on it for how much calories are burned, after all each body’s metabolism works differently as well as the BMR, it differs from one body to another.

At the end of the day, fitness trackers can not be accounted or relied on for an accurate amount of how much your body has burned calories. It is always best to keep up with a professional rather than a device.

How Does a Fitness Tracker Measure Your Heart Rate?

How Does a Fitness Tracker Measure Your Heart Rate?Lately fitness trackers have invaded the sports world by a storm, it is quite rare now to find a fitness tracker that does not have a heart rate tracking feature. The big questions here are how does it do that? And how precise can it be?

Usually any fitness tracker can also measure your activities such as the distance you walk, the number of steps you climb and the calories you burn, that is why these trackers are becoming an essential device for athletes in order for them to keep tabs on their health stats.

Do Wearable Heart Trackers Actually Work?

These trackers can be placed on your wrist, they are adorned with sensors that can measure the acceleration, frequency, duration, intensity and patterns of your movement while you are exercising, one of the most important sensors of a tracker is the light sensor; these fitness trackers use light to measure the body’s pulse.

The process works by shining a light into the blood vessels located in your wrist after that they start to detect the changes in the blood volume which happens every time your heart beats and pushes blood throughout your body. Sensors on the device detect how much light your blood vessels reflect back thus less reflected light means a higher blood volume.

This technology is called photoplethysmography or PPG for short.

Furthermore, this technology is not only used in the tracker devices but is also used in hospitals. Experts confirm that the devices that use this technology are very accurate at monitoring the heart rate, in spite of that these devices verge to be a bit imprecise when a user starts making an intense activity.

How Accurate Are Fitness Tracker Heart Rate Monitors?

Long story short, these wearable technologies rely on using an LED light to make the capillary veins in your wrist visible to a sensor in order to measure how fast your blood is pumping, after that this information is then interpreted as your heart rate and later is presented in a “beats per minute” data format.

However, if you want to receive an accurate reading, the wearer should be totally still thus any simple move can effect the tracker’s heart rate reading.

If you want a device that solely works on getting an accurate heart rate reading, then a fitness tracker might not be your call.

We suggest getting a heart rate monitor watch, it requires you to be still so it could read your rate, and unlike most trackers; instead of taking an idle reading of your pulse, the device requires you to touch your finger to a built-in pad to such a degree the results have a more accurate reading, one that fitness trackers aspire to have.
