Apple has initiated a comprehensive health study in collaboration with Brigham and Women’s Hospital, leveraging iPhone, Apple Watch, and AirPods technology to advance understanding of physical health, mental wellbeing, and their interconnections.

The Apple Health Study, available through the Research app, represents a significant advancement in using consumer technology for medical research. This initiative builds upon Apple’s previous health studies, which have already engaged over 350,000 participants across the United States.

Dr. Calum MacRae, a cardiologist and Professor of Medicine at Harvard Medical School, emphasizes the study’s potential: “We’ve only just begun to scratch the surface of how technology can improve our understanding of human health. This study will explore connections across different health areas using technology that people carry with them daily.”

The research spans multiple health domains, including cardiovascular health, mental wellness, sleep patterns, and cognitive function. What sets this study apart is its holistic approach to understanding how different aspects of health interact – for example, examining how mental health affects heart rate or how sleep quality influences exercise performance.

Dr. Sumbul Desai, Apple’s vice president of Health, explains the broader implications: “Research and validation are foundational to our health initiatives. The insights gained have already led to innovative features like the Vitals app on Apple Watch and Walking Steadiness on iPhone.”

The study’s methodology leverages Apple’s vast user base and device capabilities to overcome traditional research limitations. Unlike conventional medical studies constrained by participant numbers and data collection methods, this digital approach allows for more comprehensive data gathering while maintaining user privacy.

Participation is entirely voluntary, with users maintaining control over their data sharing preferences. The study is currently open to U.S. residents who meet age requirements and complete the informed consent process. Apple emphasizes that participant privacy is protected, with the company having no access to identifying information provided through the Research app.

The potential impact extends beyond immediate health monitoring. Early detection of health changes could lead to more proactive healthcare approaches. For instance, the study suggests that identifying early hearing health changes might help reduce cognitive decline risks.

This initiative represents a significant step forward in democratizing medical research by combining academic expertise with widely available consumer technology. The study is accessible through version 6.0 of the Research app on iPhone models running iOS 16 or later.
