The Fitbit Sense and Sense 2 are two of the best health-focused smartwatches out there because of the comprehensive health features Fitbit has packed into a smartwatch, including features to help you monitor and manage stress!
With the Sense 2, you can even keep an eye on your stress levels or elevated body reactions throughout the day using the new cEDA sensor and an updated algorithm.
Your Fitbit Sense series watch (or Fitbit Charge 5, which also offers this feature) helps you understand how stress often occurs, what might have triggered it, and how you mentally and physically respond to that stress.
You track your stress with your Fitbit Sense series watch and daily stress management score in the Fitbit app to understand how many physical signs of stress you have on a daily basis.
Armed with this information, you can then take appropriate coping measures. This is very useful for effectively managing your overall stress levels and hopefully avoiding the negative effects that stress has on your health and well-being.

How does Fitbit detect and monitor stress?
With the Sense, Fitbit has doubled down on what it does best: tracking your health.Fitbit Sense is equipped with a biosensor core.
In other words, this smartwatch has been equipped with the latest Fitbit sensor technology to measure your heart rate, blood oxygen saturation level, heart rate variability, skin temperature and electrodermal activity.
And with the Sense 2 model, Fitbit has updated its electrodermal activity sensor so that it monitors your body's reactions all day and continuously (called the cEDA sensor). experience stress.
Electrodermal activity is the core component of Fitbit's stress detection
This is unique to the Fitbit Sense and Charge 5 as the watch uses its Body Response sensor (EDA on the original Sense and Charge 5) or (cEDA on the Sense 2) along with theEDA-Scan-Appto detect the electrodermal activity and then calculate the stress.
This is also calledGalvanic skin reaction sensorand measures small changes in the conductivity of your skin's surface.
Fitbit's proprietary algorithms calculate your stress score based on an assessment of your electrodermal activity AND other metrics like your heart rate variability.
Research has shown that heart rate variability increases during relaxation and recovery activities and decreases during stress. Accordingly, HRV is typically higher when the heart is beating slowly and decreases when the heart is beating faster.
While other wearable platforms like Garmin create a stress score based primarily on heart rate variability, the Fitbit Sense can take advantage of the built-in EDA sensor.
The new PurePulse 2.0 continuous heart rate monitor correlates electrodermal activity with HRV to give you a more accurate stress score.
Other cheaper wearables out there primarily use HRV using the optical heart sensor.
Because heart rate and HRV generally have an inverse relationship, these sensors examine your heart rate data and determine if you are in a state of stress.

The best sensors for detecting stress are the ones that canMeasure the cortisol level in your sweatand draw conclusions. However, this technology has yet to be commercialized by the leading wearables manufacturers.
Existing research on electrodermal activity and emotional state
A long list of research makes the connection between our emotional states and GSR (Galvanic Skin Response) activity, suggesting that our sweat glands go into overdrive mode when we experience certain emotions. (1).
This is especially true for emotions surrounding “anger” and 'Happiness.'
In one study, researchers used happy and sad music on participants while collecting a range of measurements such as GSR and heart rate.
They found a significant increase in GSR activity related to the SCR (skin conductance response) in the happy music state compared to the sad music state. (3).
How do I use the Fitbit Sense stress management feature?
There are two specific features when it comes to understanding your stress level with your Fitbit Sense.
The first of these is operated via the EDA Scan app on your Fitbit Sense
Tapping the EDA Scan app requires you to sit still and relax for more than two minutes while the system collects information and stores it in the mindfulness tile.
An EDA scan accomplishes two things:
- It gives you an insight into your current stress level (right now).
- Provides strategies for managing and reducing stress through breathing exercises, meditation, and other mindfulness practices.
Unlike other sensors, the EDA scan app does not work automatically in the background. You must manually open the app and take a measurement.
How to use the EDA Scan app on your Fitbit
- On your Fitbit, tap OpenEDA-Scan-App.
- ChooseFast scan. You can also chooseguided sessionfor a longer 60-minute relaxation. The 2-minute quick scan shows your EDA response, while the longer session lets you listen to a meditation session in the Fitbit app for up to 60 minutes.
- Place your palm on the screen - your hand must touchall 4 sidesof the Fitbit frame.
- Remain calm and calm during the scankeep your hand on your Fitbit for the full 2 minutes. If you remove your hand, the scan will pause. To continue, put your hand back on the screen.
- Wait for the Fitbit to vibrate, indicating the scan is complete!
- Tap Record to reflect how you're feeling, tap Skip, then swipe down to see the summary of your EDA scan, including your number of EDA responses, your heart rate at the start and end and each added reflection.
EDA response rates vary. However, you'll get fewer EDA responses when you're calmer and more when you're under stress.
Stress management score missing from Fitbit Sense?
We've seen several new Fitbit Sense users complain about not being able to find their stress levels. The stress management score seems to be missing from their Fitbit app.
Please note this is normal. It typically takes 4 to 5 days for the Fitbit Sense system to record all of your activity and evaluate the baseline metrics to generate a stress score.
If you recently bought the Fitbit Sense and are simplesee a zero scorefor stress management it is normal. Give it a few days, and then your daily stress scores will appear on the Today tab.
Fitbit recommends wearing the Sense for a full day before it can show you your stress score, but we've found it takes more than two to three days for some users.
Also note that the stress score is only available to you when you use the heart rate function. This is enabled by default on your Fitbit Sense and Versa 3.
If you don't see a sleep metric, make sure your heart rate tracking feature is working.
The good news is that unlike older Fitbit devices, you can't turn off heart rate tracking on the new Sense or Versa 3.
If your HR tracking isn't working, it may mean the sensor is defective and you'll need to contact Fitbit Support and request a replacement device.
How to access the stress score on Fitbit Sense
The second stress management feature is embedded in the Fitbit app.
Here you can find your stress management score and see how your body responds to stress based on your heart rate, sleep and activity data.
Start by tapping the Today tab. Next, tap the Stress Management Score tile. Here you can find the daily stress score. If you swipe up on this screen, you will see a history of your stress levels.
When you open the Fitbit Premium app on your mobile device, your stress management score is available along with some insights right after your activity/step metrics details.
New Sense owners can use Fitbit Premium for free for a year, after which a monthly subscription is required.
Understanding your Fitbit Sense stress levels
Stress scores range from 1 to 100. According to Fitbit, a higher number indicates you are less stressed.
You will receive a daily stress score every morning. This number does not change throughout the day.
- A high score indicates that your body is showing fewer signs of physical stress, so you might consider starting a new project or exercising.
- A low reading indicates your body is showing signs of stress, so you might want to take a break — go to bed early or meditate.
The scoring function uses more than ten different factors to calculate the aggregate stress score. These factors are clearly divided into three main categories.
- Responsiveness: heart rate data and Electrodermal Activity (EDA),
- Stress balance: Effect of physical activity on your stress level.
- Sleep patterns: Effect of sleep duration and quality on your stress level.
A quick tip:If you want to measure your stress at intervals throughout the day, use the EDA Scan app and take a reading.
How to improve stress management score on Fitbit?
Try to reduce stress in your daily life! Easier said than done, here are some pointers that can help you manage your stress better and improve your score.
- Intelligentes Training. Please don't overdo it and push too hard for too many days without allowing your body to recover. Train consistently. As mentioned earlier, a higher HRV means less stress. You can get a higher HRV by using a certain amount of sprint training or interval training. Try it and see how it feels.
- Steady healthy diet.
- sleep quality.It's not just about the amount of sleep you get, but your sleep quality and consistency. It is beneficial to go to bed and wake up at similar times each day.
- auto regulationIn general, it's helpful to try to get your body on a consistent schedule (particularly with sleep and food). Your body does things more efficiently when it knows what to expect.
- hydration.The more hydrated you are, the easier it is for your blood to circulate and deliver oxygen and nutrients to your body. It's a good goal to drink nearly an ounce of water for every pound of body weight every day.
- Avoid alcohol.A night of drinking can negatively affect your HRV for up to five days and indirectly affect your stress score.
- PracticeResonanzatmungat least twice a day. You can use the guided meditations available through the Fitbit Premium app.
The Fitbit app has tools to help you manage stress, including mood logging to reflect how you're feeling and content related to mindfulness, sleep, activity, and nutrition. Try these features and see if you can manage your stress better.
In Summe,The Fitbit Sense is definitely a cutting-edge smartwatch focused on providing a comprehensive toolset to help you lead a healthy lifestyle.
Fitbit's stress management capabilities through the new Sense take a unique multi-pronged approach to tracking stress by integrating common metrics such as heart rate variability (HRV) and resting heart rate elevation, as well as EDA readings and heart rate readings captured during sleep.
The only small caveat is that we hope that the next generation will include a better EDA app design that is more intuitive.
