Fitbit is introducing stress management tools to millions of its users by bringing them to its activity trackers for the first time.

The tech giant's new Stress Management Score will be made available to all FitBit heart-rate enabled devices, providing a daily assessment of the user's body’s ability to handle stress based on their activity levels, sleep and heart rate.

Fitbit Premium members will get a detailed breakdown of their Stress Management Score, including information on their exertion, sleep patterns and responsiveness.

Premium members will also have access to a range of workouts and nearly 200 mindfulness sessions from popular brands like Aaptiv, Aura, Breethe and Ten Percent Happier to manage stress.

This includes Deepak Chopra’s Mindful Method, a wellness collection created for Premium with more than 30 sessions to make a mindfulness practice more accessible.

Fitbit is introducing four new sessions to Mindful Method, focused on bringing the power of mindful awareness to many real-life situations.

Deepak Chopra said: "I share Fitbit’s belief that mindfulness and mental wellbeing are an important part of our holistic health.

"By better managing your emotional wellbeing, it can help make a positive lasting impact on your overall health, including better sleep, improved mood and more meaningful personal relationships.

“For example, I regularly see my heart rate lower after doing a meditation session and over time, my heart rate variability trends have improved.

"Mindful Method makes a regular mindfulness practice easy and accessible – no matter whether you are learning how to begin, or are interested in taking your mindfulness practice to the next level.”

The roll out of Stress Management Score coincides with the launch of Fitbit Luxe, a "fashion-forward fitness and wellness tracker" designed to help users take a more holistic approach to their health and wellness.

With a luxury bracelet designed by Gorjana and a colour touchscreen, the tracker has a focus on fashion.
