Guide to lowering your resting heart rate with wearables

Your resting heart rate is important. This is evidenced by a report published recently in the Canadian Medical Association Journal which suggests it can even be used to predict your chance of keeling over!

The study of over 1.2 million people found that those who have a resting heart rate (RHR) of 80 bpm are 45% more likely to die of any cause in the next 20 years compared to those with the lowest measured heart rate of 45 bpm. Researchers found that the risk of dying from any illness or health condition raises by around 9% for every 10 beats per minute over. The chance of suffering a fatal heart attack or stroke rises 8%.

What is a resting heart rate and why is it so important?

guide to lowering your resting heart rate with wearables 2 - Guide to lowering your resting heart rate with wearablesThe basal or RHR is defined as the heart rate when a person is awake, in a neutrally temperate environment, and has not undergone any recent exertion or stimulation. Measurements are typically taken in the morning, after a rest day because the sympathetic nervous system is no longer active following strenuous exercise. A normal RHR for a healthy adult is anywhere between 60 and 80 beats per minute.

As you can see from the chart comparing RHR to fitness level, the fitter you are, generally the lower your RHR. This is due to the heart getting bigger and stronger with exercise, and getting more efficient at pumping blood around the body. This means, at rest more blood can be pumped around with each beat, therefore less beats per minute are required.

So, how do you rank?

What factors influence my resting heart rate?

The above table provides only a generalization of your fitness and health. There are many other factors which may account for variations in heart rate such as medications and illness. Even the air temperature and weather can effect your day to day readings. So for a more accurate idea of where you average, its best to take into account readings over a longer period.

Other factors that can affect your RHR include:

  • Age: As you age, due to the decline of physical fitness, your readings will typically go up.
  • Dehydration: If you are feeling dehydrated your heart has to work harder to maintain an adequate body temperature and to provide enough oxygen and nutrients to muscles.
  • Stress: If you are feeling stressed, the central nervous system orders the heart, brain and muscles, to prepare for a fight-or-flight situation. This leads to an increase in your RHR.
  • Genome: Finally, your genome is another important factor that can influence your RHR.

Your individual readings can also be used to assess fatigue levels. If you find that your RHR is elevated from its normal average (by more than 7 bpm), that could be a sign that you’re not fully recovered from a hard workout. You should then consider taking a few days to allow your body time to recover.

How to use wearables to lower your readings?

The good news is, whatever your RHR there are things you can do to improve it. It’s not rocket science – exercise is the best way to lower your values. When you workout regularly, your heart pumps more blood before it contracts, which results in fewer beats per minute. Regular amounts of high intensity exercise are particularly important, as they strengthen the heart and improve its efficiency. When your RHR decreases as a result of training, it is a sign that your aerobic fitness has improved.

Other ways to lower your RHR include staying hydrated, reducing stress, limiting the intake of stimulants such as caffeine and coffee, limiting alcohol intake and eating a healthy, balanced diet. Getting enough quality sleep is also important, as is maintaining a healthy body weight.

Essential reading: Best devices for heart zone training

It is advisable to monitor how your resting heart rate is changing over time in order to know whether you are making progress. Luckily, new advances in technology have made this easier than ever. Many fitness trackers and smartwatches will automatically figure out your RHR for you. All you need to remember is to wear them. They will also provide a historical record, which you can tap into to see how your readings are changing over time.

Best wearables to track your resting heart rate

The heart rate monitor inside your activity tracker may not be as precise as the equipment used in doctors offices and hospitals, but researchers say that smartwatches and wristbands are accurate enough for most consumers’ needs. Nevertheless, its worth noting, these are not medical devices so should not be treated as such.

Most half-decent fitness trackers and smartwatches will keep tabs on your RHR. That is, if they have a built-in heart rate sensor. What follows are a few of our favourites.

Fitbit’s flagship fitness tracker is a sleek looking device that carries over all of the features found on its predecessor, and upgrades it with a bigger OLED display. Waterproofing is another important upgrade. Charge 3 has a water-resistance rating of 5 ATM which means you can dunk it down to depths of 50 metres.

The device has an embedded optical heart rate sensor and its heart rate tracking is continuous and fairly accurate. It will also keep track of your resting heart rate throughout the day and display the result within the app, plotting its course over a period of the last 30 days.

Plus there are a few new features that tap into your hear-rate readings. The most useful one is called Cardio Fitness Level. It gives you a snapshot of your fitness level using a personalised Cardio Fitness Score, which is based on your VO2 Max and lets you know how you compare to people the same age and gender.

The Garmin Vivosmart 4 ticks most the boxes for those looking for a 24/7 fitness buddy. This is a particularly popular choice with women due to its sleek form factor. Its body houses sensors allowing it to track step, distance, calories, floors and sleep, along with some more advanced metrics such as VO2Max.

Thanks to Garmin Elevate wrist heart rate technology you still get around the clock heart rate monitoring. As part of that 24/7 monitoring, when users are not on the move the device measures heart-rate variability which it uses to calculate and measure stress levels.

Garmin has also slapped on some new features in the fourth generation device. In additional to all the usual fitness tracking smarts, Vivosmart 4 comes with a blood oxygen sensor and it will keep tabs on your body’s energy reserves to let you know when its time to push hard when to rest.

Most Garmin devices dish out RHR figures and they all use the same Garmin Connect app. If you are after a more fully featured device, check out our overview of the company’s fitness trackers. Or you could perhaps opt for one of Garmin’s dedicated sports watches.

apple announces third generation smartwatch with lte 5 - Guide to lowering your resting heart rate with wearablesThe fitness tracking information on the Apple Watch is comprehensive in that it wants you to exercise for 30 minutes per day, stand for at least a minute for 12 hours and burn enough calories every 24 hours. It’ll also tell you steps and distance travelled, which is a staple of the tracker.

The Series 5 delivers a few improvements over its predecessor, most notably an always-on display. There’s the addition of a compass and a better processor but other features are pretty much identical to the Series 4 device. Which means you get the ECG sensor, a next generation accelerometer and gyroscope which can sample motion data 8 times faster, GPS and more.

Apple’s optical heart rate sensor is one of the best ones on the market. The watch will alert you when it detects an abnormal spike in your readings and you’ll get your RHR in the morning.

This is hands down the most advanced smartwatch you can buy today. But with each iteration, it’s getting closer to becoming a must have health device as well.

    For those not ready to get a band that includes heart rate there are some free phone apps that will do a good job of measuring resting heart rate. Our favorite app measures resting heart rate, automatically logs the lowest reading of the day, and displays the trends in an unique and informative way. Ok, maybe we’re a little biased because we developed it at SensorBLE. You can find the Resting Heart Rate app for Android phones at https://play.google.com/store/apps/details?id=com.sensorble.hrmonitor and for the iPhone at https://appsto.re/us/PXv_8.i
