Apple has broadened the availability of its sleep apnea detection feature to several additional countries across Europe, Asia, South America, and beyond. This functionality—available on the latest Apple Watch models—reflects Apple’s continued push to position its wearable devices as powerful tools for health and wellness.
😴 What is Sleep Apnea Detection on Apple Watch?
Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during the night, often without the individual realizing it. Apple Watch detects sleep apnea by using its built-in accelerometer to track subtle wrist movements associated with disrupted respiratory patterns.
When interruptions in breathing occur over multiple nights, the system identifies signs consistent with sleep apnea and provides insights through the Health app on iPhone. Users must wear the Apple Watch for several consecutive nights to receive an accurate assessment.
🌐 Newly Supported Regions for Sleep Apnea Detection
The feature is now available in the following locations:
- 🇦🇷 Argentina
- 🇦🇺 Australia
- Christmas Island
- 🇨🇨 Cocos (Keeling) Islands
- 🇪🇨 Ecuador
- 🇭🇲 Heard and McDonald Islands
- 🇭🇳 Honduras
- 🇮🇩 Indonesia
- 🇲🇩 Moldova
- 🇳🇫 Norfolk Island
- 🇷🇸 Serbia
- 🇹🇼 Taiwan
- 🇹🇭 Thailand

These additions bring the total number of countries with access to sleep apnea detection to over 150 worldwide. The feature is available on the Apple Watch Series 9, Apple Watch Series 10, and the Apple Watch Ultra 2.
🫀 Expanded Heart Health Features
Apple has also extended the availability of several key heart health features:
- ECG (Electrocardiogram)
- Irregular Heart Rhythm Notifications
- AFib History (Atrial Fibrillation)
These features are now live in:
- 🇦🇷 Argentina
- 🇨🇷 Costa Rica
- 🇷🇸 Serbia
AFib History is tailored for individuals diagnosed with atrial fibrillation by a medical professional. It allows users to track the frequency and duration of their episodes directly on their Apple Watch. Meanwhile, Irregular Rhythm Notifications monitor for abnormal heart patterns—such as unusually high or low heart rates—that could indicate a more serious condition.
The ECG feature, available on compatible Apple Watch models, can provide a one-lead electrocardiogram capable of detecting atrial fibrillation, bradycardia (low heart rate), and tachycardia (high heart rate).
🗺️ Global Availability
All three heart-related features—ECG, Irregular Heart Rhythm Notifications, and AFib History—are now supported in more than 150 countries. Apple continues to update its Apple Watch feature availability list to reflect new rollouts and regional support.
