Sleep Iq's Heart Rate Tracking: How Does It Work?

SleepIQ technology is an operating system for smart beds that uses sensors to track your sleep. SleepIQ technology is embedded in Sleep Number beds and can track your heart rate, movement, and breathing. The data is then sent to a web/smartphone app, which provides you with a SleepIQ score, a grade for how well you slept. The Sleep Number app allows you to control your bed, track your sleep, and understand how sleep impacts your overall health and wellness. While SleepIQ technology is impressive, privacy experts have raised concerns about the fate of personal health information collected by smart mattresses and sleep apps.

How does Sleep IQ track heart rate through a mattress?

Sleep Number's Sleep IQ technology is an operating system for smart beds that uses sensors to track your sleep. The Sleep IQ sensors can track your heartbeat, movement, and breathing. The data is then sent to a web/smartphone app, which provides you with a Sleep IQ score, a grade for how well you slept. The score is given on a scale of 5-100 and is calculated based on your sleep session, biometrics, sleep goal, and circadian rhythm. The technology also allows you to input your lifestyle activities to see how they affect your sleep quality.

Sleep IQ uses embedded ballistocardiography, along with network connectivity, signal processing, and machine learning, to detect heart rate, breathing rate, and sleep vs. wake states. The smart bed sensors automatically start data collection when the user enters the bed and stop when the user leaves. The processed data is sent to the cloud for storage and further analysis.

Sleep Number collects more than 8 billion biometric data points every night, which are gathered each second and sent through the internet to the company's servers. This data is used to inform consumers about their health and improve the company's products. However, privacy experts have raised concerns about the collection and storage of personal health information. Sleep Number allows users to turn off data recording at any time through the app or remote, and users can also remove their Wi-Fi network connection from the bed.

While Sleep IQ technology is impressive for sleep tracking, there are concerns about the price and potential stress induced by over-tracking sleep. There are also cheaper and easier alternatives available, such as wrist wearables, which may become more advanced over time.

How does Sleep IQ use ballistocardiography to track heart rate?

SleepIQ technology, embedded in Sleep Number beds, uses ballistocardiography to track an individual's heart rate. This technology uses high-resolution full-body ballistocardiography (BCG) readings from an inflatable air bladder within the bed mattress. The use of BCG as a passive-sensing technology enables the measurement of motion, position changes, breathing, and small movements within the body such as those generated by the ejection of blood with each heartbeat.

The Sleep Number bed's sensors are placed in the mattress and monitor the body while the user sleeps. The bed collects data on the heart rate through a technology called biofeedback, which involves using sensors to detect physical changes in the body. The sensors pick up pulse variations from blood flow in the body. This information is then transmitted to a corresponding app or display. The bed’s sensors are sensitive enough to distinguish between heartbeats and other movements, allowing for accurate heart rate readings without the need for wearable devices.

SleepIQ technology supports overall wellness by using heart rate data in conjunction with other metrics. For example, the Sleep Number bed measures heart rate variability (HRV), the variation in time between heartbeats, which is commonly used to assess the activity of the autonomic nervous system (ANS). Changes to ANS function, as reflected in HRV, can result from factors including lifestyle, aging, cardiorespiring illnesses, sleep state, and physiological stress. By tracking HRV, SleepIQ technology can provide insights into an individual's overall health and sleep quality.

SleepIQ technology has been found to have moderate to strong correlations in measuring sleep data compared to in-lab polysomnography (PSG), including sleep versus wake states, breathing rate, and heart rate. This suggests that SleepIQ technology may provide reliable measurements of sleep quality and access to sleep metrics for large populations over longer periods than what is currently achievable with PSG.

What kind of sensors does Sleep IQ use to track heart rate?

SleepIQ is a feature included in Sleep Number beds that monitor an individual's heart rate, among other things, and relays the information to their phone. Sleep Number beds collect more than 8 billion biometric data points every night, gathered each second and sent via an app through the internet to the company's servers. This data is used to inform consumers about their health and improve the company's products.

Sleep Number's privacy policy states that it collects personal information, including names, age, weight, height, and gender. If a consumer creates a user profile on the bed's app, this personal information is expanded to include specifics about movement, positions, respiration, and heart rate. This data is collected even for children if parents create a user profile for them.

While the exact sensors used by SleepIQ are not publicly known, some users have speculated that the technology is based on commercially available sensors and signal processing. There are no wires going into the mattress, only an air tube to the air pump, so it is possible that an air pressure sensor in the pump is used to detect heart rate.

Privacy experts have raised concerns about the fate of personal health information collected by smart mattresses, sleep trackers, and sleep apps. While Sleep Number has stated that it does not share any SleepIQ or biometric data outside the company, privacy policies of many devices that track and transmit personal information allow for the sharing of data that has been stripped of personal identifiers.

How does Sleep IQ track heart rate in relation to sleep/wake states?

SleepIQ technology is an operating system for smart beds that uses sensors to track your sleep. The Sleep Number smart bed uses embedded ballistocardiography, network connectivity, signal processing, and machine learning to detect heart rate, breathing rate, and sleep vs. wake states. The data collected by SleepIQ technology is sent to the cloud and stored for further analysis.

The SleepIQ score is a grade for how well you slept, based on data collected by the sensors in the mattress. This includes information about your heart rate, movement, and breathing. The score is designed to assess how well a consumer slept and is used heavily in the company's marketing. It is calculated on a scale of 5-100 and is meant to be used to monitor your progress over time. The score can also be impacted by factors such as sleep session, biometrics, sleep goal, and circadian rhythm.

The SleepIQ technology automatically begins data collection as soon as the user enters the bed and stops once the user leaves. It does not offer the option to start or stop the reading manually. However, users can turn data recording off at any time using the Sleep Number app or remote, which will prevent data from being recorded for either side of the bed. Additionally, users can remove their Wi-Fi network from the bed if they no longer want their bed connected to Wi-Fi.

The heart rate and breathing rate data collected by SleepIQ technology are averaged and are not recorded in real-time for diagnostic purposes. These averages help users track consistency and recognize changes in their biometrics. It is important to note that these averages can be impacted by factors such as cardiovascular conditioning, daily stress, alcohol use, age, weight, and overall health.

The smart bed sensors automatically start data collection when the user enters the bed and stop when the user leaves. The data is then sent to the cloud and stored for further analysis.

SleepIQ's heart rate tracking capabilities are particularly notable, as it can detect heart rate through the mattress without any wires or devices that need to be worn or charged. This is made possible by high-resolution full-body ballistocardiography (BCG) readings from an inflatable air bladder within the mattress. BCG enables the measurement of motion, position changes, breathing, and small movements within the body, such as those generated by the ejection of blood with each heartbeat.

By tracking heart rate and other biometrics, SleepIQ provides insights into overall health and sleep quality. For example, a lower resting heart rate may indicate a person is a runner or engaged in regular cardiovascular activity. Additionally, tracking heart rate over time can help identify deviations from a person's average, which may be indicative of stress, alcohol use, or other factors influencing heart rate and sleep quality.
