How does Circular track my Resting Heart Rate (RHR) and how to use it?

Please read first our previous article about What increase and decrease Rested Heart Rate (RHR).

Resting Heart Rate can help you get an idea of your overall wellness and fitness, and can help you set fitness goals.

The fitter you are, generally the lower the Resting Heart Rate. This is due to the heart getting bigger and stronger with exercise, and getting more efficient at pumping blood around the body, so at rest, more blood can be pumped around with each beat, therefore fewer beats per minute are required. 

Usually, the best moment to measure RHR is just after waking up but we can’t force you not to be active after waking up. So we find that the best measure is taken when getting in your bed before going asleep. We give one average reading per day inside the “Activity analysis” circle.

Circular takes a measure of your Resting Heart Rate when resting, although not sleeping (as your heartbeat significantly drops then).

Your own baseline RHR

A RHR between 60 and 100 beats per minute (BPM) is considered normal, but 60 to 80 is optimal. Generally, a lower resting heart rate indicates more efficient heart function and greater cardiovascular health. Research has connected a higher Resting HR with a higher risk of cardiac events like stroke and heart attack.

Many factors influence what’s normal for any one person. Genetics, age, and gender all have an impact on your baseline HR and play a part in determining your normal range. Those aren’t really things that you can change, but there’s one factor you can: your fitness level.

Circular automatically determines your baseline RHR for you. You are able to find it in the “Activity analysis” circle, by swiping to the RHR graphs. It is represented as a blue line for comparison. As your fitness levels are what can impact the most efficiently your RHR for the better, Kira is made to recommend certain activity programs or lifestyle changes for you.

Average Resting Heart Rate Circular

What can be deduced from RHR:

You’re not active enough

If you’re sedentary most of the day, your RHR likely approaches or exceeds the top end of the range above. This may be because your heart is less efficient. The good news? By regularly engaging in moderate to vigorous aerobic activities (brisk walking, biking, swimming), you will help your heart become more efficient at pumping blood which will lower your Resting Heart Rate over time. Even modest reductions in RHR can dramatically reduce your risk of cardiovascular disease and add years to your life!

You’re overtraining

While pushing your body can lead to great gains, it can also be detrimental. If you notice an increase in your Resting Heart Rate when you’re going heavy on the training and light on the rest, your body may be telling you that you need to scale back. By giving it the proper rest it needs, your body can repair and adapt and you may bounce back stronger than ever.

You’re too stressed

Prolonged mental and emotional stress can also cause your RHR to creep up over time. Try adding relaxation into your day: read, meditate, go for a walk with friends. Regular relaxation activities may help you combat your stress and which could lead to a lower RHR.

You’re sleep-deprived

Always exhausted? Chronic sleep deprivation which can lead to fatigue, a slower metabolism, and extra snacking can also raise your RHR. Aim for at least 7-9 hours of sleep each night.

You’re dehydrated

During a hot summer day, if you notice a temporary increase in your RHR, your body might simply be trying to cool down. However, it could also mean you’re dehydrated especially if you’re thirstier than usual, your mouth is dry, and your pee is more yellow than normal. To help lower your RHR, drink more water.

You’re developing a medical condition

If you experience shortness of breath, unusual fatigue, dizziness, and your RHR has increased, you might be at risk for a medical condition. High RHR can be a sign that something is abnormal. However, even if you have a low RHR combined with symptoms (like those above), it could indicate an issue.

Don’t just look at the RHR, combines it with all the metrics especially HRV. If your RHR looks unusual but you don’t feel lightheaded, weak, short of breath, dizzy, then there is nothing to worry.

Resting Heart Rate increases with age
Most of the time your RHR can be modified. Unfortunately, as you get older, your RHR tends to increase. To reduce the impact that aging can have on your cardiovascular system, you can help maximize your results by exercising within your target HR zone to help lower your RHR. You can compare to other people your sex and age to get a good idea if you’re in the averages. But keep in mind an average isn’t personal (genetics too are involved!) and doesn’t necessarily reflect the best practices and target RHR. We recommend you to stick with Circular’s recommendations.

Medication affects Resting Heart Rate
Changes in your RHR can also result from over-the-counter or prescription medications. Medications to treat asthma, depression, obesity, and attention deficit disorder tend to increase your RHR. However, medications prescribed for hypertension and heart conditions (beta blockers, calcium channel blockers) typically decrease your resting heart rate.


Circular will send you recommendations concerning your wellness if it detects something abnormal. Never forget to never just look at the numbers, but also evaluate how you feel for yourself.

The RHR is a very good tool to correlate with your HRV, your sleep and, your activity. If the HRV and RHR indicators are relevant together then you can consider analyzing your vital signs over the next few days.

Although, when thinking solely about your wellness, RHR is a great tool and the programs designed in the programs circle might help you out. Don’t forget to also follow Kira’s recommendations about your sleep schedule. You will always have a great companion by your side in your Circular app (Kira), that’ll try to do its best at helping you higher you RHR in good proportions. And remember that her recommendations are measured and have a good chance of reflecting situations you’ll be better off changing.

We remind you that the Circular™ ring is not a medical device and should not be used to diagnose or monitor a pathology.

In practice 

In your Circular app, dive into the activity analysis circle. On the first page is displayed, along with other metrics, your daily RHR measure. As stated previously, there is one measurement a day.
