Why Smartwatches Can Be Helpful for Heart Health
Smartwatches are more than just timekeepers—they’re like having a small health assistant on your wrist. For older adults and caregivers, they can provide peace of mind by tracking heart rate, detecting irregular rhythms, and even alerting someone if a fall occurs. These devices use optical sensors to measure your pulse continuously, giving you real-time data about your heart’s activity.
Heart rate monitoring is especially important for older adults because:
- Detecting irregular rhythms: Some smartwatches can spot atrial fibrillation (AFib), a common irregular heartbeat in older adults that may increase the risk of stroke. Note: ECG readings are not diagnostic and require professional medical interpretation.
- Tracking activity levels: They can show how your heart responds to exercise, helping you stay active safely.
- Providing trends over time: Instead of relying on a single reading, smartwatches show patterns in your heart rate, which can be more useful for spotting changes.
Smartwatches aren’t meant to replace traditional health monitoring, like blood pressure cuffs or visits to your doctor. Instead, they complement those methods by giving you more frequent and convenient data. For example, if your smartwatch shows an unusually high or low heart rate, you can check in with your doctor rather than waiting for your next appointment.
This guide is for older adults who want to use smartwatches for heart health and caregivers who want to support their loved ones. We’ll cover how to choose the right smartwatch, set it up, interpret the data, and use it safely.

- Garmin: Garmin Connect app (iPhone or Android)
Step 3: Turn on the smartwatch and pair it with your phone
Turn on your smartwatch by pressing and holding the side button (or following the manufacturer’s instructions). Then, open the companion app on your phone and follow the on-screen instructions to pair the two devices via Bluetooth. This usually involves scanning a QR code on the smartwatch or entering a code shown on both devices.
Step 4: Set up heart rate monitoring
Once paired, enable heart rate monitoring in the smartwatch settings and the companion app. Most smartwatches will automatically start tracking your heart rate, but you may need to adjust settings to get the most accurate readings. For example, you can set the smartwatch to monitor your heart rate continuously or only during workouts.
Step 5: Adjust settings for notifications and alerts
If you want to receive alerts for abnormal heart rates or falls, enable these features in the settings. For example:
- High or low heart rate alerts: Set a range (e.g., below 50 bpm or above 120 bpm) to get notified if your heart rate goes outside normal limits.
- Fall detection: Turn on fall detection so the smartwatch can automatically call for help if you take a hard fall.
- Emergency SOS: Set up emergency contacts so the smartwatch can call them in case of an emergency.
Step 6: Wear the smartwatch correctly
For accurate heart rate readings, the smartwatch must fit snugly on your wrist, with the sensor making good contact with your skin. The band should be tight enough that you can slide one finger under it, but not so tight that it feels uncomfortable. If the band is too loose, the sensor won’t get a clear reading. Note: Optical heart rate sensors may have reduced accuracy for individuals with darker skin tones or tattoos.
Troubleshooting common setup issues:
- Bluetooth pairing problems: Make sure Bluetooth is turned on for both your phone and smartwatch. Restart both devices and try pairing again.
- Heart rate not updating: Ensure the smartwatch is snug on your wrist and the sensor is clean. If the issue persists, check the companion app for settings or updates.

Understanding Your Heart Rate Data
Smartwatches provide a lot of heart rate data, but it’s important to know what it all means. Here’s a breakdown of the key metrics and what they might indicate for older adults.
Key Heart Rate Metrics
- Resting heart rate (RHR): Your heart rate when you’re at rest, usually measured first thing in the morning. A lower RHR generally indicates better cardiovascular fitness. For older adults, a normal RHR is typically between 60 and 100 beats per minute (bpm).
- Maximum heart rate: The highest heart rate you can safely reach during exercise. It’s often calculated as 220 minus your age. For example, if you’re 70, your maximum heart rate would be around 150 bpm.
- Heart rate during exercise: Your heart rate should increase during physical activity. If it doesn’t rise as expected, it could indicate a problem with your cardiovascular system.
- Heart rate variability (HRV): A measure of the variation in time between your heartbeats. Higher HRV is generally a sign of good health and resilience to stress.
Normal Heart Rate Ranges for Older Adults
Heart rate ranges can vary depending on age, fitness level, and overall health. Here are some general guidelines for older adults:
- Resting heart rate: 60–100 bpm
- During moderate exercise: 50–70% of your maximum heart rate
- During vigorous exercise: 70–85% of your maximum heart rate
If your heart rate is consistently outside these ranges, it’s worth discussing with your doctor. For example, a resting heart rate below 50 bpm or above 100 bpm may warrant further investigation.
Identifying Abnormal Readings
Smartwatches can alert you to potential issues, but it’s important to know what to look for:
- Tachycardia: A heart rate that’s consistently above 100 bpm at rest. This could be caused by stress, dehydration, or an underlying health condition.
- Bradycardia: A heart rate that’s consistently below 60 bpm at rest. While this can be normal for athletes, it may indicate a problem in older adults, especially if accompanied by dizziness or fatigue.
- Irregular rhythms: If your smartwatch detects an irregular heartbeat, such as atrial fibrillation (AFib), it may alert you. AFib is a common condition in older adults and can increase the risk of stroke. Some smartwatches, like the Apple Watch Series 4 and later, include an ECG app to detect AFib. Note: ECG readings are not diagnostic and require professional medical interpretation. Apple Watch ECG is available on Series 4 and later.
When to Contact a Doctor
Smartwatches are useful for spotting trends, but they’re not a substitute for professional medical advice. Contact your doctor if you notice any of the following:
- Your heart rate is consistently above 100 bpm or below 50 bpm at rest.
- You experience symptoms like dizziness, chest pain, or shortness of breath along with an abnormal heart rate.
- Your smartwatch detects an irregular rhythm, such as atrial fibrillation, and you haven’t been diagnosed with it before.
- You notice sudden changes in your heart rate patterns that don’t match your usual activity levels.
