5 smartwatch functions that will be useful for those who care about health

Smartwatches are designed to stimulate their owners to move more actively. Regular notifications that it’s time to warm up and that Usain Bolt woke up in your body yesterday, and today – a turtle, motivate you not to lower the bar. However, these devices have much more opportunities to make their owner healthier. Together with HerzBand, we analyze the functions of smartwatches that will help keep the body in optimal condition.

Counting the number of steps and calories burned

Literally, every smartwatch model, from budget to premium versions, is equipped with an accelerometer today. This device counts the number of steps taken per day, as well as the total distance traveled, and transmits the data to proprietary applications like “Activity”. There, the user can see extended statistics of movements, estimate at what time of the day he was moving most productively and, if necessary, adjust his lifestyle. Some smartwatches can also calculate the number of calories burned per day. The counter displays how much the body has burned during rest, walking, and training. An extremely convenient function for those who care about the indicators of KBZHU (calories/proteins/fats/carbohydrates) and notes the balance of eaten and burnt.

Heart rate and blood oxygen level measurement

This is a more serious function, which requires a more sophisticated technological filling. A pulse oximeter that measures oxygen in the blood (saturation) is not found in all watches, even from the premium price segment. Saturation measurement is essential to ensure that all tissues and organs are receiving sufficient oxygen. A level of 95% and above is considered normal. At saturation below 90%, a person may experience shortness of breath, headache, and pain in the chest, and lose consciousness. Prolonged hypoxemia (a decrease in the level of oxygen in the blood) provokes irreversible consequences for the respiratory system and the body as a whole. The situation is similar to the pulse – a sudden increase in heart rate can be a signal of possible health problems that usually go unnoticed. We are talking about arrhythmia, which is often not given special importance, and this symptom can become a “wake-up call” for more serious diseases. The smartwatch can measure heart rate and oxygen saturation in two modes: manual and automatic. At the first, the owner of the device independently opens the corresponding application and can track the indicators on the screen. In the second, the device takes measurements after a certain time, which can also be configured (for example, intervals from 10 to 60 minutes). During training, the smartwatch shows dynamic values ​​of heart rate and oxygen saturation. On the graph, you can see at what moment the body was most difficult, and based on this data, adjust the load so that they are not excessive. You can also set up notifications when the numbers are too high – the watch vibrates and tells you to take a break.

Body temperature measurement

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. However, HerzBrand succeeded. Their model of a fitness bracelet Elegance ECG-T is able to measure body temperature using a CT1711 chip. After the measurement results are displayed on the dial screen. The user can also set up the automatic activation of the function at certain intervals or measure the temperature on his own. It is also possible to activate the temperature rise alert system. In the current environment, 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 inconveniences.

Sleep monitoring

You can also set up a quality sleep mode with your smartwatch. The built-in application allows you to set the time of going to bed and the moment of waking up. As soon as the required value appears on the watch, it will send a notification that it is time for the user to go to bed. Many watches also automatically record the time you fall asleep and wake up, the total duration, the number of awakenings, and even the phase of sleep (light to deep). After that, you can give the quality of night rest a grade from 1 to 5. The system works best if you do not remove the bracelet all night, and for this, the device will need high autonomy.

Pressure measurement

Modern watch models use the photoplethysmographic method for measuring blood pressure. The same technology is used in conventional blood pressure monitors. The device reads the pulse wave, the data is processed by a microcomputer and then displayed on the screen. In HerzBand Elegance ECG-T this function is also implemented. And although the fitness bracelet cannot determine ultra-precise pressure indicators, since it is not a professional medical device, it still shows approximate values ​​close to true. In order to synchronize the smartwatch and the tonometer as much as possible, you need to calibrate them manually. To do this, it is enough to indicate in the application your standard blood pressure level. You can also take an electrocardiogram with the HerzBand Elegance ECG-T. It is enough to open the application or find its icon from the general menu. Then you need to put your finger on the electrode located at the end of the case and wait about a minute. ECG data is immediately displayed on the application screen, after which it can be saved in PDF, JPEG, and other formats. In addition to the ECG trace, the report provides an overall assessment of the measurements and a rough estimate of the likelihood of potential heart disease. This watch can make an excellent tandem with a cardiologist, informing both the owner and his doctor about possible problems in time.
