Disclaimer: The elevated temperature detection feature is designed to indicate deviations from your typical temperature pattern and is not a medical thermometer. It should not be used to diagnose fever or any medical condition. For accurate temperature readings or health concerns, always use a clinical thermometer and consult a healthcare professional. 

Body temperature is a crucial biomarker as it has the ability to impact various aspects of your health and can indicate potential signs of illness.

The TempTech 24/7 module is able to track body temperature 24/7, including overnight and during a workout.  It is normal for your temperature to rise and fall at night as inflammatory responses are amplified to fight sickness or health problems. By following your temperature trends over the long term you can build better night time habits as well as stay on top of your fluctuations which may indicate the onset of an illness.

Your body temperature can change periodically while you work-out and so it's important to stay on top of your data. Especially as heat exhaustion is a common problem in people over 65, with health conditions or those living in a hotter climate; Tracking your live exercise temperature shifts will help you stay informed, and prevent yourself from overheating which can benefit your performance & post-workout recovery.

Calibrating your baseline temperature

Body temperature readings are reliant on your baseline temperature. When you initially install your ScanWatch 2, your baseline temperature will be set at a standard value. However, this value will be refined and tailored to your individual physiology as you continue using your device — it will continue to gather more temperature measurements over the course of a few days.

When first wearing ScanWatch 2 the Temperature Module will take approximately 15 minutes to calibrate to your body temperature. If you remove the watch it may need to recalibrate when you put it back on. In this case, you may also notice irregular temperature readings for a few minutes after you take off the watch.

Note: The algorithm is designed to assess temperature trends over time rather than focusing on a single reading. Its accuracy is intended to reflect overall patterns rather than individual measurements, and it should not be directly compared to occasional spot checks.

Viewing your continuous temperature reading on your watch

On your ScanWatch 2 your temperature reading is activated by default, and is always shown as the last measurement in the menu. In order to view it at any time simply navigate the menu using the crown and you should see your instant temperature reading. You can now see your temperature displayed, proceed with a simple press to display the baseline variation.

Viewing your continuous temperature data in the Withings App:

In order to view your Body Temperature graph on the Withings App, follow these simple steps:

1. Open the Withings App.
2. Find and tap "Continuous Temperature" on your Home tab.
   
   
3. You can now see your Continuous Temperature detailed view.
   
   

The status indicates if your temperature is elevated or usual. This status is based on nighttime measurements, as they are more consistent from night to night and make it easier to detect shifts in your baseline. During the day, your temperature can fluctuate significantly due to various factors such as stress or physical activity.

You can follow your temperature trends long term thanks to the Week, Month, Quarter, Year and All views.

Workout Temperature Zones:

With ScanWatch 2, optimizing your physical performance is made easier through the workout zones feature. You’ll get key insights into your body temperature as it changes. The 3 temperature zones have been carefully designated so you can understand and use them to support your well-being: 

• Warm Up Zone: This is the lowest temperature zone, that’s optimal for preparing your body before starting your workout. Spending the first few minutes in this zone helps to raise your body temperature gradually, priming your muscles for optimal performance. 
• Performance Zone: This zone is where you should stay for the majority of your workout. It provides ideal conditions for peak muscle performance, allowing you to workout efficiently and achieve better overall results. 
• Overheating Zone: This zone should be avoided whenever possible. Exercising in this zone can have negative consequences related to overheating — muscle cramps, nausea, headaches, dizziness, confusion, or even loss of consciousness. Ensuring you stay clear of this zone is essential for your well-being while you workout.

If your body temperature reaches the overheating zone, you should immediately slow down your physical activity and allow your body temperature to return to a lower zone, ideally the performance zone or a normal body temperature for you.

The technology behind the Temperature module:

The ScanWatch 2 includes our TempTech24/7 module which consists of an optimized combination of 4 sensors (thermistor, heat flux, PPG, accelerometer), delivering 4 inputs ( heat flux, “skin” temperature, heart rate, actigraphy), powering an algorithm that delivers body temperature, along with a tailored in-app data visualization algorithm capable of body temperature baseline and notifications for the user.
