Oura's Use of METs with Activity
Oura uses METs, or metabolic equivalents when measuring your daily activity output. This article explains why Oura uses 1.5 METs as the lowest threshold for activities that contribute to your daily active calorie burn.
1.5 METs is a True Reflection of Active Calorie Burn
1 Metabolic Equivalent (MET) corresponds with Resting Metabolic Rate (RMR). RMR is the total number of calories burned while your body is completely at rest. This is part of what your body needs to sustain itself while you’re awake. Because accuracy is at the heart of how Oura provides you with personalized insights, by using 1.5 METs as the lowest threshold for activities that contribute to your daily active calorie burn, we’re able to generate a value that reflects only calories burned through physical activities—as opposed to a combination of calories burned through physical activity and those acquired through bodily maintenance that takes place while you’re at rest. You can find further details on this topic outlined below.
Sedentary vs. Physical Activities
During sedentary activities, METs range from 1 to 1.5. Sedentary activities include dining, or lounging while watching television. In contrast, active calories relate to intentionally active tasks or activities (e.g., household chores, walking the dog, or dancing). Physical activities typically result in calorie burn greater than 1.5 METs.
Accuracy Above Everything
Active calories above 1.5 METs are typically associated with active energy burn. Using 1.5 METs as the threshold for active calories prevents you from accumulating large amounts of active calories from low-intensity activities. This increases the accuracy of your Activity Score, and metrics found on the Activity tab—and doesn't exaggerate calories burned while you're seated or at rest.
