What You'll Learn
Use a smartphone app
If you want to track your sleep without wearing a device, you can use a smartphone app. Many apps can track your sleep if your phone is nearby. For example, iPhone users can use the Bedtime feature to track their sleep. You can also use third-party sleep tracking apps, such as those offered by Fitbit. While these apps may not be as accurate as wearable devices, they can still provide valuable insights into your sleep patterns.
The Health app on the iPhone can help you set sleep goals and create a customized sleep schedule. You can set the number of hours you want to sleep, as well as your bedtime and wake-up times. To view your sleep history, simply open the Health app and tap "Browse" at the bottom of the screen. From there, you can access your sleep data, including the time and percentage spent in different sleep stages such as Awake, REM, Core, or Deep sleep.
Additionally, the Samsung Health app can be used in conjunction with a Galaxy Watch or a Galaxy Ring to track your sleep. The app allows you to view your sleeping time, record your snoring, and access sleep coaching options. By wearing your Galaxy Watch or Galaxy Ring while you sleep, you can analyze your sleep patterns, including your blood oxygen and skin temperature. This data is then synced with the Samsung Health app, providing you with valuable insights into your sleep quality.
It's important to note that sleep-tracking apps may not always be entirely accurate. They often rely on actigraphy, which measures movement, to determine sleep. This can lead to instances where the app assumes you are sleeping when you are actually awake but still, or awake when you are actually asleep. For medically accurate sleep-tracking data, a polysomnography test is recommended.

Try a ring sleep tracker
If you're looking for a way to track your sleep without wearing a watch, a sleep-tracking ring could be the perfect solution. These small, unobtrusive devices comfortably slip onto your finger, where they can collect a variety of health metrics and insights.
One of the most popular options is the Oura Ring. Oura combines top-quality hardware with smart algorithms to track your heart rate, body temperature, blood oxygen levels, and movement. It automatically recognizes activities, breaks down each night's sleep, and even adjusts goals based on your readiness. The Oura Ring Gen 4 promises up to 8 days of battery life, though in practice, it's closer to 5 or 6 days. It's worth noting that Oura is the only smart ring in the top tier that requires a monthly subscription.
Another option to consider is the Ultrahuman Air, which offers great sleep and stress tracking and around 6 days of battery life. The RingConn Gen 2 is also a strong contender, boasting the smallest footprint and the longest battery life of up to 12 days. It provides excellent sleep tracking and 24/7 stress tracking.
The Samsung Galaxy Ring is another option that can analyze your sleep, including blood oxygen and skin temperature, and provide useful data in the Galaxy Wearable and Samsung Health apps on your phone.
Smart rings are a great choice if you want to track your sleep without the bulk of a watch. They offer a more elegant way to monitor your sleep and health, with the added benefit of shorter charging times.

Wear a watch sleep tracker
If you're looking for an alternative to the S3 for tracking your sleep, you might want to consider a watch sleep tracker. These devices can be strapped to your wrist and are designed to monitor your sleep patterns. Some popular options include the Fitbit watch, the Oura ring, and the Samsung Galaxy Watch.
The Samsung Galaxy Watch, for example, can detect and calculate your sleep patterns. By connecting it to the Samsung Health app, you can view your sleeping time, record your snoring, and even use sleep coaching options. The watch can also be used to control smart devices, such as your TV, to ensure you don't stay up too late.
To use the sleep tracking feature on the Galaxy Watch, you'll need to enable it in the Samsung Health app. This involves opening the app on your watch, navigating to Settings, and turning on features like "Blood oxygen during sleep."
Another option is the Apple Watch, which has built-in sleep tracking capabilities. However, reviews of its sleep tracking accuracy are mixed, with some users finding it useful while others have had different experiences.
In general, watch sleep trackers can provide a wealth of sleep data, but their accuracy may vary. They often measure inactivity as a way to estimate sleep, and they can be useful for recognizing patterns in your sleep habits. For more precise data, a medical sleep study that monitors brain waves would be necessary. Nonetheless, watch sleep trackers are a convenient and accessible way to gain insights into your sleep health.

Monitor your heart rate
Monitoring your heart rate while sleeping can help detect irregularities and lead to better overall health and sleep quality. Typically, a normal resting heart rate is between 60 and 100 beats per minute (bpm), while a normal heart rate during sleep drops to between 40 and 50 bpm.
There are several ways to monitor your heart rate without wearing a watch. One way is to use a chest-band device. These monitors are considered the most accurate as they measure your heart rate directly rather than your pulse rate. Chest-band devices use electrical detection to track the electrical activity of your heart through a band that wraps around your chest. To improve electrical conduction, the band must be wet or you can use a conductive gel where the sensors touch your skin.
Another option is to use a smart ring, such as the Oura Ring. These devices are very new, so there aren't many commercially available yet. The Oura Ring measures your heart rate and heart rate variability, as well as sleep latency (how long it takes you to fall asleep) and your overall sleep quality.
You can also monitor your heart rate using a smartphone app. For example, if you have an Apple iPhone, you can use the Health app to track your sleep and view your heart rate, respiratory rate, and average temperature. However, Apple warns that these last two metrics are not intended for medical use. To use this feature, you need to wear your Apple Watch to bed and ensure it is charged to at least 30% before sleep.
Additionally, some companies are starting to offer smart sensors that integrate into your bed. These sensors can track your sleep and heart rate without the need to wear any devices. However, if you suspect you may have a sleep disorder, it is best to consult a doctor, who may recommend an in-lab or at-home sleep study with professional equipment for more accurate heart rate readings.

Measure your respiratory rate
Respiratory rate is the number of breaths you take per minute. It is one of the main vital signs, along with blood pressure, pulse, and temperature. A person's respiratory rate naturally changes during sleep and in response to factors like exercise and illness. It tends to slow while sleeping, reaching its slowest during deep sleep. In REM sleep, a person's respiratory rate increases and becomes less regular.
The normal respiratory rate for healthy adults is between 12 and 20 breaths per minute. At this breathing rate, the carbon dioxide exits the lungs at the same rate that the body produces it. Breathing rates of below 12 or above 20 can mean a disruption in the breathing processes.
To take an accurate measurement, watch the person’s chest rise and fall. One complete breath comprises one inhalation when the chest rises, followed by one exhalation when the chest falls. To measure the respiratory rate, count the number of breaths for an entire minute, or count for 30 seconds and multiply that number by two.
There are also wearable devices that can compute the respiratory rate during sleep, obtaining measurements without the conscious knowledge of the user. Commercial wearable devices accomplish this through photoplethysmography (PPG), usually at a single point of contact, either on the wrist (smartwatches, trackers, straps) or the finger (rings).
