Imagine your smartwatch is like a detective watching you closely. It listens to how fast your heart beats and how evenly it goes up and down. When you're stressed, your heart works harder, and the watch notices these changes, just like a detective sees clues at a crime scene. That’s how it knows when you're feeling tense or worried.
Examples
- Your smartwatch sees your heart beat faster when you're worried.
- It notices that your heartbeat becomes uneven during a tough meeting.
- When you finish work and your heart slows down, the watch knows you're relaxed.
