How Fitbit Calculates Resting Heart Rate
Fitbit devices determine resting heart rate by analyzing heart rate data gathered during both sleep and waking periods, focusing particularly on phases of inactivity. This multifaceted approach ensures comprehensive insight into the user's heart rate patterns.
Heart Rate Data Collection
To achieve accurate resting heart rate readings, Fitbit continuously monitors the user's heart rate variability, the time variations between consecutive heartbeats. The device collects data both when the user is asleep and during periods of wakefulness when no physical activity, such as walking, is detected.
Importance of Wearing Your Fitbit to Bed
For precision in resting heart rate calculations, users are advised to wear their Fitbit trackers while sleeping. This habit allows the device to record a more consistent and comprehensive dataset, which is critical for calculating resting heart rate accurately.
Calculation and Display of Data
Fitbit's algorithms integrate the heart rate data from both inactive and sleep states to estimate the resting heart rate. Despite daily fluctuations in physical activity or sleep quality, the Fitbit resting heart rate measurement remains stable, updating only when significant deviations based on nocturnal heart rate are detected. Users can view their resting heart rate trends through graphs available in the Fitbit app.
Acknowledging Potential Inaccuracies
While generally reliable, Fitbit's resting heart rate readings can sometimes be higher than the user's lowest heart rate measured during sleep. Such discrepancies might occur if the Fitbit is not worn to bed or due to inherent limitations in the device's tracking algorithms.
How Does Fitbit Calculate Resting Heart Rate?
Fitbit calculates resting heart rate using advanced heart rate monitoring technologies and algorithms. It measures heart rate both during sleep and periods of inactivity throughout the day. This comprehensive approach ensures accuracy in capturing your lowest sustainable heart rate, providing valuable insights into your heart health.
Technology Behind the Measurement
Utilizing PurePulse technology and photoplethysmography (PPG), Fitbit tracks heart rate continuously. PPG operates by shining a green light on the skin and measuring changes in light absorption caused by blood flow. This technology, sustained by over 50 patents, captures precise heart rate data which is vital for calculating resting heart rates.
Algorithmic Calculation
Fitbit's algorithms integrate data from both awake and asleep states to estimate the resting heart rate. The tracker's algorithm may adapt over time, utilizing current and previous days' data to refine its estimations. Fitbit recommends wearing the tracker during sleep to enhance the accuracy of the resting heart rate measurements.
Understanding the Metrics
The resting heart rate value typically stands higher than the heart rate measured while sleeping. This metric reflects the rate when you are awake, calm, and undisturbed by recent physical activities. By monitoring these variations, Fitbit helps you understand your overall heart health and well-being.

Understanding How Fitbit Calculates Resting Heart Rate
Example 1: During Sleep
Fitbit calculates resting heart rate by analyzing heart rate data when the user is asleep. The device uses the heart rate readings from the sleep period, considering the time when the heart rate is at its lowest, typically during deep sleep stages.
Example 2: Right After Waking Up
Another method involves measuring the heart rate immediately after waking up. Fitbit takes into account the first 30 minutes after awakening, excluding any periods of sudden heart rate increases due to movements or disruptions.
Example 3: Periods of Inactivity
Fitbit also assesses periods of inactivity during the day. The device identifies times when the user is awake but inactive for long periods, capturing the lowest heart rate data to contribute to the resting heart rate calculation.
Example 4: Continuous Tracking
Continuous heart rate tracking technology on Fitbit devices updates resting heart rate values by integrating data collected throughout the day. This comprehensive approach ensures more accurate and reflective resting heart rate measurements.
Example 5: Algorithmic Analysis
Fitbit devices utilize proprietary algorithms to analyze fluctuations and patterns in heart rate data, fine-tuning the resting heart rate estimation. By filtering out anomalies and considering trends, the algorithm provides a stable and reliable resting heart rate figure.

Frequently Asked Questions
How does Fitbit calculate resting heart rate?
Fitbit calculates resting heart rate using an algorithm that includes data from both when the user is awake and asleep. It measures the heart rate when the user is inactive during the day and throughout the sleep period.
What method does Fitbit use to measure resting heart rate?
Fitbit measures resting heart rate by collecting heart rate data when the user is sleeping and also during periods of inactivity while awake. This data is then processed through an algorithm to calculate the resting heart rate.
Why is it recommended to wear the Fitbit while sleeping for accurate resting heart rate measurements?
Wearing Fitbit while sleeping is recommended for accurate resting heart rate measurements because the device needs to gather data on your heart rate during sleep, which significantly influences the resting heart rate calculation.
Does Fitbit resting heart rate calculation change throughout the day?
No, Fitbit does not recalculate resting heart rate throughout the day. It recalculates resting heart rate at the beginning of each day based on heart rate data gathered while sleeping and when awake but inactive.
Conclusion
Understanding how Fitbit calculates resting heart rate is crucial for optimizing your fitness tracking and overall health monitoring. By cleverly intertwining heart rate data from your least active periods, particularly during sleep, Fitbit offers a refined resting heart rate calculation.
