Total Burn, or your total daily energy expenditure includes all the calories you've burned during the day whether active or resting. Oura begins calculating your total burn at 4 am by logging the estimated amount of calories your body burns while at rest, also known as your Basal Metabolic Rate (BMR). Continuing to calculate until 4 am the next morning, all calories burned by your daily activity are added to the sum. 

While physical activity increases your daily calorie burn, most of your total burn comes from your BMR.

Activity Burn is an estimate of your net calorie burn - it shows the calories you've burned by walking, training or doing other activities (the portion that exceeds 1.5 MET level). Tracking your activity burn can help you to balance out your current activity level and your calorie intake, which is key to good recovery and maintaining a healthy weight.
