Wearable Technology Surge: Transforming Health Monitoring for Americans
WASHINGTON, D.C. (7News) — The prevalence of smart devices among Americans has reached unprecedented levels, as individuals increasingly seek tools to facilitate healthier lifestyles.
From popular options like the Apple Watch, Garmin, and Fitbit, to the Samsung Galaxy Watch and Oura Ring, these wearable technologies can monitor a wide array of health metrics, including heart rate, physical activity, sleep quality, and stress levels.
A recent study featured in the journal NPJ Digital Medicine substantiates this growth. Researchers at Yale School of Medicine scrutinized national health survey data from 2020 to 2024, discovering a remarkable 36.1% increase in wearable device ownership among U.S. adults, culminating in a total of 41.1% by 2024.
However, the findings reveal a paradox: while the majority of wearable users express a willingness to share health data with healthcare providers, less than 20% have followed through.
Researchers underscore the latent potential of wearable technologies to enhance healthcare, albeit acknowledging that user engagement remains crucial for their efficacy, as many individuals fail to consistently utilize their devices or incorporate the gathered information into their medical routines.

Dr. Sos Mboijana, an internal medicine practitioner with The Permanente Medical Group, attests to witnessing this trend’s rapid ascent in his clinical practice.
“The accessibility has certainly increased,” Mboijana remarked. “With costs diminishing significantly, I observe a notable surge in these devices within my practice of internal medicine.”
Patient Questions: “Can I Trust This?”
Dr. Mboijana notes that the inquiries he receives predominantly revolve around the reliability of the information these devices provide, rather than the gadgets themselves.
“Common questions include, ‘Is this accurate? Does it contribute to my health? How can I leverage this to enhance my health outcomes?'” he elaborated. “There’s typically a health-related query behind it.”
He perceives this growing curiosity as a positive development.
“When patients approach me with these questions, it indicates their engagement and interest in tracking their health metrics. That, in itself, is a victory.”
Sleep Scores: Useful Feedback, Not Medical Diagnoses
Numerous smartwatches and rings now provide users with nightly sleep scores derived from data on sleep duration and stages.
Dr. Mboijana cautions that these scores should be regarded as useful personal insights rather than definitive medical evaluations.
“While these devices assess various sleep data effectively, they have yet to achieve validation as medical instruments,” he stated.
The challenge lies in the proprietary algorithms utilized by numerous companies to compute metrics such as “sleep readiness” and “recovery,” which remain elusive for medical personnel aiming to diagnose or treat conditions based on these scores.
“Many of the metrics, including sleep and recovery scores, tend to be proprietary and not rigorously validated concerning health outcomes,” Dr. Mboijana added.
Conversely, certain wearable features possess clinical validation. For instance, he refers to FDA-cleared electrocardiogram (ECG) functions in select smartwatches and continuous glucose monitors used by diabetics as reliable tools for medical practice.
Focus on Trends, Not Isolated Sleep Scores
Rather than fixating on a singular sleep score, Dr. Mboijana advocates for adopting the mindset of athletes who monitor their performance trends over time.
“The key is to acclimatize to the device, utilize it over the long term, and observe broader patterns,” he suggested. “This approach emphasizes trend analysis.”
He notes that the mere presence of a new device can temporarily disrupt sleep, as users are acutely aware of being monitored.
“Allow some time for adjustment,” he advised. “Evaluate the trends in your data over time, rather than getting caught up in daily fluctuations.”
Instead of concentrating on an isolated sleep score, consider what variables might have influenced it. Did late-night exercise, alcohol consumption, or travel affect your rest? Over time, these trends may unveil valuable insights into your overall health and lifestyle.
The Utilization of Wearable Data by Physicians
The Yale study indicates that while most wearable users are open to sharing their data with healthcare professionals, only a minority follow through.
Dr. Mboijana affirms that even when patients do share their data, healthcare systems are still grappling with effective methods for its utilization.
“We are inundated with data,” he remarked. “The conundrum lies in organizing this information effectively so that it can be integrated into electronic health records and applied meaningfully.”
In his dual role as Medical Director for AI and Emerging Technology, Dr. Mboijana posits that artificial intelligence will eventually aid physicians in analyzing wearable data far more adeptly.
“We are caught in this transitional phase where we’re overwhelmed,” he explained. “It’s vital to distill insights that are beneficial, not just for me, but for your health as well.”
He encourages patients to share their wearable data during appointments, although they should not anticipate immediate responses to every chart or graph their device generates.
Guidelines for Selecting the Appropriate Wearable
With a plethora of watches, rings, and fitness trackers available, Dr. Mboijana advises against succumbing to flashy advertisements. Instead, consumers should begin with a fundamental question: What is your objective?
“Am I aiming to lose weight? Focus on my metabolic health? Train for a marathon? What are my objectives for acquiring this device?” he queried.
He recommends consulting a primary care physician prior to any purchase, particularly given the significant costs associated with many wearables.
“Manufacturers provide enticing options, but starting at a manufacturer’s site can lead to confusion,” he warned. “A doctor can assist in aligning a device to a patient’s health aspirations and clarify which metrics hold the strongest medical validation.”
The Future of Wearable Health Technology
The scholars responsible for the Yale study assert that wearable devices hold considerable promise in the realm of preventive healthcare as technology evolves and usage becomes more commonplace.
Dr. Mboijana concurs.
“We are transitioning from simple tracking devices to sophisticated physiological monitors,” he stated. “These technologies are advancing significantly.”
He believes that artificial intelligence, along with other emergent technologies, will ultimately enable practitioners to convert the deluge of wearable data into actionable, personalized health recommendations.
For now, his guidance is straightforward: avoid becoming fixated on a solitary sleep score or heart rate reading.
Instead, leverage wearable devices to gain insight into your patterns, maintain engagement with your health, and discuss longer-term trends with your healthcare provider.
This is where the true value of current wearable technology lies—an area poised for greater evolution in the future.
