Your smartwatch isn’t just a fashion accessory or a step counter—it’s a powerful health-monitoring tool. One of its most valuable features is the ability to track your heart rate and alert you if it goes too high or too low. Whether you’re an athlete optimizing workouts, managing stress, or simply staying proactive about your health, setting up heart rate alerts can be a game-changer.  

In this guide, we’ll walk you through enabling heart rate alerts on popular smartwatches in the U.S., including Apple Watch, Samsung Galaxy Watch, Garmin and Kloo Watch. Let’s get started!  

Why Set Up Heart Rate Alerts?
Heart rate alerts help you:  
- Monitor safety during workouts (avoid overexertion).  
- Detect irregularities (e.g., unusually high or low resting heart rate).  
- Track stress or anxiety levels (elevated heart rate can be a signal).  

Note:While smartwatches are helpful, they’re not medical devices. Always consult a doctor for health concerns.  

How to Enable Heart Rate Alerts on Popular Smartwatches  

1. Apple Watch (watchOS 9 or later)  
1. Open the Watch app on your paired iPhone.  
2. Go to My Watch > Heart.  
3. Tap High Heart Rate or Low Heart Rate.  
4. Set your thresholds (defaults are 100 BPM for high, 40 BPM for low).  
5. Toggle alerts On.  

2. Samsung Galaxy Watch (Wear OS) 
1. Open the Samsung Health Monitor app on your phone.  
2. Tap Heart rate.  
3. Toggle High/Low heart rate alerts.  
4. Adjust thresholds (defaults: 100 BPM high, 40 BPM low).  
5. Confirm to save.  

3. Kloo Watch  
1. Open the H Band app on your phone.  
2. Tap your profile icon > your device.  
3. Select Heart Rate Settings.  
4. Enable High & Low Heart Rate Alerts.  
5. Customize thresholds (Kloo watch recommends 100-150 BPM for high, 40 BPM for low).

4. Garmin (Venu, Forerunner, or Fenix Series)  
1. Press the watch’s menu button.  
2. Go to Settings > User Settings > Heart Rate.  
3. Select Heart Rate Alerts.  
4. Set High Alert and Low Alert thresholds.  
5. Enable alerts during activity, rest, or both.  

What’s a “Normal” Heart Rate? 
- Resting heart rate: 60–100 BPM (athletes may dip lower).  
- During exercise: Up to 70–85% of your max heart rate (calculated as 220 minus your age).  

Adjust your thresholds based on your fitness level and doctor’s advice.  

Troubleshooting Tips
- Alerts not working? Ensure your watch fits snugly (loose bands reduce accuracy).  
- Too many false alerts? Raise/lower your thresholds slightly.  
- Battery drain? Continuous heart rate monitoring uses more power—schedule rest periods if needed.  

Stay Informed, Stay Healthy
Heart rate alerts turn your smartwatch into a 24/7 wellness companion. Whether you’re pushing limits in a spin class or recovering on the couch, these notifications keep you in tune with your body’s signals.
