— the level of stress in the body is a very relative indicator. The metric that determines heart rate variability (see above) helps to evaluate it. However, the user's breathing rate and oxygen consumption are taken into account. Stress levels are usually shown on a scale from 0 to 100, often indicating the number of hours the body is under stress and the time it takes for it to return to normal. From a practical point of view, this parameter allows you to determine the most optimal body mode for playing sports or all kinds of activities.
