Smartwatches are designed to encourage their owners to move more actively. However, these devices have much more potential to make their wearer healthier. Thus, we analyzed the functions of smartwatches that will help keep the body in optimal condition. These features are present in Huawei watch GT 3 pro 46mm and also in other brands’ smartwatches:
Count Steps and Calories Burned
Literally, every model of “smart” watches, from budget to premium versions, is now equipped with an accelerometer. This device counts the number of steps taken per day, as well as the total distance traveled, and transmits data to branded applications like Activity.
There, the user can see extended movement statistics, evaluate what time of the day he moved most productively, and, if necessary, adjust his lifestyle. Some smartwatches also know how to count the number of calories burned per day. The counter displays how much the body has burned in rest mode, walking and training.
Measurement Of Pulse and Blood Oxygen Levels
Already a more serious function, which requires more complex technological stuffing. A pulse oximeter that measures blood oxygen levels (saturation) is far from being found in all watches, even from the premium price segment. Saturation measurement is essential to make sure that all tissues and organs are getting enough oxygen.
During training, the smartwatch shows dynamic values of heart rate and saturation. On the graph, you can see at what point the body was most difficult, and based on this data, adjust the loads so that they are not excessive. You can also set up notifications when the indicators are too high – the watch will vibrate and prompt you to take a break.
Using a watch as a thermometer is still perceived as something out of the ordinary. This is because not all manufacturers have figured out how to fit temperature sensors together with the rest of the filling and not lose the compactness of the device.
After the measurement results are displayed on the dial screen. The user can also set the function to turn on automatically at certain intervals or measure the temperature on their own. You can also activate the temperature alert system.
In the current conditions, this function is literally worth its weight in gold. For higher measurement accuracy, it is worth placing the watch under your arm – if the situation requires you to act quickly, you can forget about the inconvenience.
With the smartwatch, you can also set the quality sleep mode. The built-in app allows you to set your bedtime and wake-up time. As soon as the required value appears on the watch, it will send a notification that the user should go to bed.
Many watches also automatically record the time of falling asleep and waking up, the total duration, the number of awakenings, and even the phases of sleep (from light to deep). After that, you can rate the quality of a night’s rest from 1 to 5. The system works best if you do not remove the bracelet all night, and for this, the device will require high autonomy.
Pressure Measurement And ECG
Modern watch models use a photoplethysmography method for measuring blood pressure. The same technology is used in conventional blood pressure monitors. The device reads the pulse wave, and the data is processed by the microcomputer and then displayed on the screen.
And even though the fitness bracelet cannot determine ultra-precise pressure indicators, since it is not a professional medical device, it still shows approximate values close to the true ones. In order to synchronize the smartwatch and the blood pressure monitor as much as possible, you need to calibrate them manually. To do this, just specify the standard level of your blood pressure in the application.
