Newer sensible watches seize each these metrics. And even when you have an older machine, you may nonetheless purchase a further HRV monitor that syncs to a smartphone app.
HRV displays whole physique stress from any supply. It doesn’t differentiate bodily versus psychological stress, and it doesn’t differentiate good from dangerous stress.
