Coospo HW807 – Make your relaxation visible. The ideal companion for VitalNerv.
Product Description
Your body talks to you – we translate it.
You already feel how the VitalNerv-Stimulator helps you reduce stress and find calm. But how deep does this relaxation truly go? The Coospo HW807 provides the proof. It translates your subjective body feeling into clear, measurable numbers.
Why we recommend exactly this sensor for VitalNerv: We rely on radical honesty and science instead of marketing hype. To test the effect of the VitalNerv-Stimulator, we measure heart rate variability (HRV). Studies (including on ResearchGate: "Heart Rate Measurement Accuracy During Intermittent Efforts...") confirm:
-
During rest phases (Your VitalNerv mode): Here, this optical sensor delivers excellent, almost ECG-accurate HRV values. It is therefore the perfect "thermometer" to see how your parasympathetic nervous system reacts to the stimulation.
-
For the sake of honesty: While it is perfect for our purposes (rest & recovery) and steady endurance sports, studies show slight deviations during extremely fast sports intervals. However, for your deep relaxation, it is the undisputed comfort winner.
Comfort meets precision: Forget constricting chest straps that disturb you during relaxation. The HW807 is worn comfortably on the upper arm – you will hardly notice it's there, while it precisely records how your stress level drops.
