Garmin devices are not FDA-approved and are not suitable for medical monitoring
Garmin is an American, Swiss-domiciled multinational technology company that specializes in GPS technology for automotive, aviation, marine, outdoor, and sports activities. They also produce wearable technology, such as smartwatches and activity trackers. While Garmin devices can track sleep and some are equipped with a pulse oximeter, it is important to note that these devices are not FDA-approved and are not intended for medical monitoring.
Garmin devices, including those with oximeters and sleep-tracking features, fall under the category of wearable technology or smartwatches. These devices are designed to provide users with information about their health and fitness, but they are not meant to be used as medical devices. While they can offer insights into your sleep patterns and blood oxygen levels, they should not be relied upon for medical diagnosis or treatment.
The pulse oximeter feature on Garmin devices, for example, can give you an estimation of your blood oxygen saturation levels. However, it is not intended to replace medical-grade equipment or serve as a diagnostic tool. Similarly, the sleep-tracking feature can provide you with data about your sleep duration and patterns, but it cannot diagnose sleep disorders or provide medical advice.
It is worth noting that while Garmin has made strides towards obtaining FDA approval for certain features, such as the ECG feature on the Epix (Gen 2) Series, this does not extend to all of their devices or functionalities. The ECG feature's approval designates the watch as a Class 2 Medical device, which requires clinical trials and various other hurdles to obtain official certification. As of now, Garmin devices as a whole have not undergone the rigorous process of FDA approval, and therefore, their data should not be interpreted as medical advice.
In conclusion, while Garmin devices with oximeters and sleep-tracking capabilities can provide valuable insights into your health and wellness, they should not be solely relied upon for medical monitoring. For any concerns or diagnoses, it is always recommended to seek professional medical advice and use approved medical equipment.

Garmin watches use reflection to measure oxygen levels, which is highly inaccurate
Pulse Ox technology uses sensors to track blood oxygen saturation levels, indicating whether the body's cells are receiving sufficient oxygen to function optimally. However, it is not intended to serve as a medical device for diagnosing or monitoring health conditions. The readings provided by Garmin smartwatches should be interpreted cautiously as they may not always be entirely accurate.
The accuracy of Garmin watches in measuring oxygen levels is questionable due to their reliance on reflected light. This method can be easily influenced by various factors, resulting in potentially misleading data. For instance, factors such as altitude, physical activity, and individual health conditions can impact the Pulse Ox readings. According to medical experts, healthy blood oxygen saturation levels typically range from 95% to 100%. Readings below 92% may be considered low and could indicate potential health concerns.
While Garmin smartwatches with Pulse Ox capabilities can offer valuable information for individuals prioritising wellness or athletic performance, they should not be solely relied upon for medical purposes. If individuals have specific health concerns or require precise monitoring of their oxygen levels, it is advisable to consult a healthcare professional and use medical-grade devices.
In summary, while Garmin watches with Pulse Ox technology provide convenient estimates of blood oxygen levels, their accuracy is questionable due to the reflective measurement method's limitations. These devices are suitable for general wellness insights but should not replace medical advice and professional diagnostic tools.

Garmin's sleep tracking feature uses secondary indicators like movement, heart rate, and pulse ox
Garmin is an American, Swiss-domiciled multinational technology company that specializes in GPS technology for automotive, aviation, marine, outdoor, and sports activities. They also produce wearable technology, including smartwatches and activity trackers. Many of their watches have sleep-tracking features, including the Forerunner 255.
Garmin's sleep-tracking feature uses secondary indicators like movement, heart rate, and pulse ox to determine when you are asleep. The watch uses your sleep window, which you set, and tries to figure out when you are asleep based on your body metrics showing you are at rest. If you have a period of relaxation before bed, the watch may overestimate your sleep duration by including that time. As with all watch metrics, these are estimates, and a small overestimation is still good enough to give you an overall picture of your sleep.
The pulse oximeter (or pulse ox) is a key feature of Garmin's sleep tracking. This measures your blood oxygen saturation during sleep. To enable this feature, you need to set up the watch as your preferred activity tracker on the app. On the home page, you can click on the watch icon, select your model, scroll to health and wellness, select pulse ox, and change it to 'all day'.
In addition to sleep tracking, Garmin watches can also track your heart rate variability (HRV). This is a measure of the variation in time between each heartbeat. HRV can be influenced by various factors, including hydration, stress, and sleep. By tracking HRV, Garmin watches can provide insights into your overall health and wellness.

Garmin's Body Battery metric guesses your sleep quality, general feeling of rest, etc
The Body Battery metric is a feature on some of Garmin's latest watches. It combines a variety of metrics to estimate your energy reserve throughout the day and your ability to focus, cope and bounce back from challenges. The higher the number (on a scale of 0-100), the greater your ability to take on challenging tasks.
Sleep and rest replenish your Body Battery, while physical activity and stress deplete it. The Body Battery metric is calculated based on changes in your heart rate, also known as HRV status, which reveal the interplay between the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) branches of your autonomic nervous system.
For example, if you have an active and stressful day, your Body Battery will drain and may still be low when you wake up the next morning, especially if you had a poor night of sleep. Alcohol is also a significant stressor for your body, and the stress of metabolizing it can degrade the restorative quality of your sleep, leading to slower recharging of your Body Battery.
By understanding how your Body Battery works, you can make small changes to your daily routines and lifestyle choices to optimise your performance and focus on what matters. For instance, if your Body Battery is consistently low, you may need to adjust your daily routine or make your rest more restful. On the other hand, if your Body Battery is fully charged, you can take on challenging opportunities, activities and tasks with confidence.
