Records respiratory rate details during sleep. Can have multiple per day if the user sleeps multiple times.

Body weight measurement.

Provides derived sleep temperature values, calculated from skin or internal device temperature readings during sleep.

A daily average respiratory rate (breaths per minute) for a day of the year. One data point per day calculated for the main sleep.

Contains a daily summary of the user's VO2 max (cardio fitness score), which is the maximum rate of oxygen the body can use during exercise.

A sleep session possibly including stages.

VO2 max value calculated based on the user's running activity. Value stored in ml/kg/min.

Represents a food measurement unit.

Captures user's heart rate variability (HRV) as measured by the root mean square of successive differences (RMSSD) between normal heartbeats or by standard deviation of the inter-beat intervals (SDNN).

Represents an Irregular Rhythm Notification alert, indicating a potential sign of atrial fibrillation (AFib). This data type is based on SaMD feature and any changes to it may require additional review.

User's heart rate zone thresholds based on the Karvonen algorithm for a specific day.

Number of calories burned due to basal metabolic rate (BMR) over a period of time.

Captures the user's instantaneous oxygen saturation percentage (SpO2).

Record of active minutes in a given time interval.

Body fat measurement.

Data Source definition to track the origin of data. Each health data point, regardless of the complexity or data model (whether a simple step count or a detailed sleep session) must retain information about its source of origin (e.g. the device or app that collected it).

Step count over the time interval.

Represents a blood glucose level measurement. LINT: LEGACY_NAMES

VO2 max measurement.

Represents an Electrocardiogram (ECG) measurement session. This data type is based on SaMD feature and any changes to it may require additional review.

Core body temperature measurement, distinct from peripheral body temperature, reflects the temperature of the body's internal organs.

Measures the daily resting heart rate for a user, calculated using the all day heart rate measurements.

Represents a food item.

Swim lengths data over the time interval.

Represents the daily heart rate variability data type. At least one of the following fields must be set: - average_heart_rate_variability_milliseconds - non_rem_heart_rate_beats_per_minute - entropy - deep_sleep_root_mean_square_of_successive_differences_milliseconds

Gained elevation measured in floors over the time interval

Energy burned as part of an activity, excluding the basal energy burn.

Internal type to capture activity level during a certain time interval.

SedentaryPeriod SedentaryPeriod data represents the periods of time that the user was sedentary (i.e. not moving while wearing the device).

A daily oxygen saturation (SpO2) record. Represents the user's daily oxygen saturation summary, typically calculated during sleep.

Holds information about food logged by a user. There are two ways of creating a nutrition log based on the food type: 1. Identified food: Using the food field, which is a reference to a Food resource. In this case fields nutrients, energy, energy_from_fat, total_carbohydrate, total_fat, food_display_name will be populated based on the referenced food. 2. Anonymous food: Using the food_display_name field and setting the nutrients, energy, energy_from_fat, total_carbohydrate, total_fat fields manually. The identified food is preferred over the anonymous food. Nutrition logs created from anonymous food are not editable.

Body height measurement.

A heart rate measurement.

Distance traveled over an interval of time.

Holds information about a user logged hydration.

An exercise that stores information about a physical activity.

Record of active zone minutes in a given time interval.

Captures the altitude gain (i.e. deltas), and not level above sea, for a user in millimeters.

Time in heart rate zone record. It's an interval spent in specific heart rate zone.
