Everything Polsen tracks,
explained.

Prolonged stress vibration

When your body has been more reactive for an extended period, your watch vibrates gently — a quiet nudge to pause, identify what's driving it, and reset with built-in Check-ins and breathing exercises.

Daily stress states

Based on how long your body stayed under physiological stress, how often it spiked, and how quickly it recovered, Polsen watches give you a daily read of how you're handling daily demands — from High Resilience to High Load or Delayed Recovery.

Cumulative Stress duration

Your Overview tracks how much time your body has spent under stress in the recent days: you can see whether pressure on your body is building, and catch early signs of wear and tear before it affects your health.

Cumulative Stress recovery & frequency

Your Cumulative Stress duration is influenced by your stress recovery and frequency: how quickly your body returns to baseline after each spike, and how often it activates throughout the day. If small things are triggering your body too often, CBT sessions help you handle daily demands better. If you're struggling to come back down, prolonged reactivity vibrations nudge you to reset.
