Fitness trackers now provide a wide range of medical data. This expands the offer. Device prices are falling. Our buying tips will help you choose.
Smartwatches and fitness trackers are becoming increasingly popular.
Fitness trackers are increasingly used to detect medical problems. The manufacturers of these models, which mostly appear in the form of watches, no longer come only from the health sector. Smartphone manufacturers such as Apple, Samsung and, more recently, Xiaomi have also presented smartwatches that go beyond simply counting steps and calculating calorie consumption.
However, these standard functions are still on board, as well as the sleep analysis, which provides you with a detailed breakdown of your nights in terms of deep sleep, light sleep and REM sleep phases. However, additional sensors and evaluations now give you a broader picture of your fitness and health.
Heart rate and oxygen saturation become standard
Heart health has come into particular focus. Therefore, almost all current fitness trackers and watches measure the wearer’s heart rate – in the case of the angular ones

to grab. The fitness bracelet costs just under 100 euros, but does without GPS and color display, among other things.
For the same price (100 euros) you can also get them

with round 1.39-inch display as well as heart rate and SpO2 sensor. The latter measures the oxygen saturation of the blood and, in conjunction with the sleep analysis, can also alert you to nocturnal breathing pauses, the so-called sleep apnea. You can see the progress of your breath in the smartphone app.
They are also equipped with an SpO2 sensor

Even more help: recognize and reduce stress

The Mi Watch also includes a breathing assistant that is supposed to help you calm down with guided breathing exercises in stressful situations. The duration of the exercises can be adjusted.
The Fitbit Sense goes one step further: In the associated smartphone app, it offers a menu item “Stress Management” in which you are informed of your stress level based on your heart rate variability (HRV), physical activity and sleep rhythm.
Under “Mindfulness” there are guided relaxation exercises that use the EDA sensor of the Fitbit Sense. This measures the electrodermal activity, which indicates stress. You can also enter your mood manually in the app.
The sleep analysis also receives an additional measurement with the Fitbit Sense: The watch measures the nighttime skin temperature on the wrist and determines fluctuations.
