While some people swear by using their Apple Watch for sleep tracking, others prefer smart rings, which are lightweight, compact, and unobtrusive.

What You'll Learn

Smart rings vs smartwatches for sleep tracking
Smart rings and smartwatches are both popular choices for sleep tracking, but there are some key differences between the two. Smart rings, such as the Oura Ring, Ultrahuman Ring, and Circular Ring Slim, are typically more lightweight, compact, and unobtrusive than smartwatches. They are also often more comfortable for overnight wear, as they are less bulky than smartwatches and don't have a screen that might disturb your sleep. Additionally, smart rings usually have longer battery lives than smartwatches, which typically require nightly charging. This makes smart rings a more convenient option for sleep tracking.
However, smartwatches have their own advantages. Smartwatches with LTE connectivity can function as standalone devices, allowing you to make calls, send SOS alerts, and access apps and voice assistants. They often have adjustable straps for a perfect fit and can be customized with different materials and colors. Additionally, some smartwatches, like the Apple Watch Series 10, offer sleep apnea detection, providing valuable insights into breathing disturbances during sleep. Other notable smartwatches for sleep tracking include the Google Pixel Watch 2, which integrates Fitbit's sleep-tracking features, and the Fitbit Charge 6, which offers reliable sleep data and a useful sleep score.
When it comes to accuracy in sleep tracking, smart rings have an edge over smartwatches. This is because smart rings collect data such as heart rate, movement, and temperature, which are essential for understanding sleep patterns. While smartwatches can also track these metrics, they may not provide the same level of detail and insights as smart rings. Additionally, the lack of a screen on smart rings might appeal to those who want to disconnect from screens, although it may be a disadvantage for those who want to control music playback or track specific activities in real-time.
Ultimately, the decision between a smart ring and a smartwatch for sleep tracking depends on personal preferences, budget, and specific needs. Smart rings are ideal for those seeking a more comfortable, discreet, and accurate sleep-tracking device, while smartwatches offer a wider range of features and functionality beyond sleep tracking.

Apple Watch Series 10 for sleep apnea detection
Sleep trackers are available in the form of smartwatches, bands, and rings. While the Oura Ring is a popular and comfortable option, some users may prefer a smartwatch.
The Apple Watch Series 10 is a great option for sleep tracking. It has a larger, brighter, and thinner display, making it more comfortable to wear at night. One of its key features is Apple's FDA-cleared sleep apnea detection. Sleep apnea is a sleep disorder in which breathing stops and starts overnight, and it is estimated to affect 936 million adults globally. The Apple Watch Series 10 can detect signs of moderate to severe sleep apnea by measuring movements in the wrist associated with breathing interruptions. This data can be viewed on a one-month, six-month, or one-year timeline in the Health app.
The watch's motion-detecting accelerometer plays a crucial role in detecting potential sleep apnea signals. It measures subtle movements in the wrist that reflect the oscillation of the chest during breathing. These readings are logged as a new metric called breathing disturbances. The watch can also track your temperature while you sleep, which can be useful for family planning. Additionally, the Sleep app helps you create a bedtime routine and schedule, and provides insights into your sleep stages and relevant data.
While the Apple Watch Series 10 is an excellent choice for sleep tracking and apnea detection, it is important to note that it cannot replicate a sleep study or provide a diagnosis. However, it can help users identify potential sleep disorders and prompt them to consult a doctor for further evaluation.
