The world’s first EDA sensor in a smartwatch
Electrodermal activity (EDA) responses are tiny electrical changes on your skin which may indicate your body’s response to stress. Sense uses a multi-path electrical sensor to detect EDA responses through your palm.
Measure your body’s response to stress
Sense’s on-wrist EDA Scan app detects your electrodermal activity while you’re doing an EDA mindfulness session. Simply place your hand over the watch, and get instant feedback. Typically, you’ll see fewer EDA responses the calmer you are.
Improve your mental health
By doing regular EDA sessions on your Sense and tracking your responses over time, you can build a mindfulness practice and improve your mental well-being. Clinical studies have shown that mindfulness-based practice, such as meditation, is most effective at reducing stress.*
Sense users see a daily Stress Management Score in the Fitbit app ranging from 1 to 100—where a higher number means you’re showing fewer physical signs of stress. It’s calculated based on three metrics: your responsiveness, exertion balance and sleep patterns.
Only Fitbit Premium members see their score breakdown.
Sense looks at your heart rate data and electrodermal activity to see if your body is showing the “fight or flight” response. A higher number means you’ve shown fewer of these signs the last few days.
Too little physical activity can raise your stress hormone levels, but too much activity can lead to fatigue and bodily stress. A higher number means you’re getting the right balance of activity for you.
Good sleep makes it easier for your body to deal with stress. A higher sleep patterns score means you’re well-equipped to handle stress based on your recent sleep patterns.
Keep track of how you’re feeling from Very Calm to Very Stressed to gain awareness of your emotional well-being and how it changes. Together, your reflections and Stress Management Scores on Sense give you a holistic picture of how well you’re handling stress.
