What Is Resting Heart Rate?
Resting Heart Rate (RHR) is the number of times your heart beats per minute when you're at rest. It's a good gauge for your sleep quality, recovery, and overall health. Normal RHR in adults can range anywhere from 40-100 BPM.
Oura monitors your resting heart rate throughout the night and displays your lowest 10-minute average. It evaluates the optimal level for your RHR by studying your data after active days and recovery days for a couple of weeks.
Oura interprets a RHR slightly below your average as a sign of good readiness, whereas an exceptionally high or low RHR is a sign of an increased need for recovery. If your RHR reaches its lowest point during the first half of your night, it can be a sign you've recovered well from the day.
What Affects Your Resting Heart Rate?
Your RHR is affected by various factors, such as physical activity, nutrition, body position, and other environmental factors. A low RHR is often associated with good fitness sound wellbeing.
Your RHR might appear elevated after a late-night workout or if your body temperature is higher than normal. Alcohol, a heavy meal before bed or late exercise speed up your metabolism and keep your RHR elevated, delaying your recovery and increasing your sleep needs. It’s normal for your RHR to be higher than usual when recovering from an intense training day. As you increase your training volumes and your fitness improves, your RHR should start to decline over time.
For women, the menstrual cycle can cause a small increase in RHR during the second half of the cycle (ovulatory and luteal phases).
