What Biomarkers Wearables Track
Modern wearables are equipped to monitor a variety of biomarkers that reveal the connection between stress and metabolism. For instance, heart rate variability (HRV) is a crucial measure of how the autonomic nervous system responds to stress, while continuous heart rate monitoring helps identify stress-induced changes over time.
Cortisol tracking has been a game-changer in this space. The CortiSense device, for example, uses sweat analysis with aptamers to measure cortisol levels at home. This gives users a way to monitor a hormone closely tied to stress, anxiety, and depression. Sweat analysis has also expanded to include the detection of electrolytes, hormones, and metabolites, offering insights into hydration, stress, and even chronic conditions.
The Aabo Ring stands out for its precision, offering continuous heart rate monitoring with 99% accuracy. It also tracks sleep patterns and blood oxygen levels, providing real-time feedback on how stress impacts recovery.
Another noteworthy advancement is in blood pressure monitoring. Novosound has developed a wearable ultrasound-based device that tracks blood pressure non-invasively, delivering results comparable to lab-level accuracy. This allows users to monitor changes in real time, which can highlight potential disruptions in metabolic health.

Next, let’s dive into the latest sensor innovations that are refining these measurements even further.
New Advances in Wearable Sensors
Recent developments showcased at CES 2025 highlight how wearable sensors are becoming more accurate and user-friendly. For example, STMicroelectronics introduced the ST1VAFE3BX bio-sensing chip, which is designed for next-generation healthcare wearables. This chip combines high-accuracy biopotential input, motion tracking, low power usage, and embedded AI capabilities.
Tedaid by Wis Medical is another standout device. Using soft electronics and machine learning, it achieves a diagnostic accuracy of 94.78%. It tracks vital signs like ECG and respiratory rates, making it suitable for both home and clinical use.
A particularly innovative concept is the Withings Omnia Health Scanner - a smart mirror that integrates multiple health-tracking technologies. It measures over 60 health parameters, including ECG readings and in-depth sleep analysis, offering a comprehensive view of user health.
Women's health has also seen advancements. The Peri AI-Enabled Tracker is designed to monitor perimenopause symptoms, providing personalized insights for better health management.
Overcoming traditional sensor limitations, researchers at the University of Arizona have introduced a novel approach. Associate Professor Philipp Gutruf explains:
"Wearable health monitoring traditionally depends on sensors that directly attach to the skin, but the skin itself constantly renews. This limits how long you can collect reliable data. With our sensor that tracks gaseous emissions from the skin, we overcome this constraint entirely."
These innovations are shaping the future of wearable technology, making it possible to measure health metrics more effectively than ever before.
Wearables vs. Lab Tests
Wearables bring unique advantages when compared to traditional lab tests. Unlike lab tests, which capture a single snapshot of your health, wearables provide continuous, real-time monitoring in everyday settings. This dynamic tracking can reveal patterns and trends that static lab results might miss.
Cost and convenience are also major benefits. For instance, measuring stress hormones like cortisol through lab tests can be expensive and often requires multiple visits to healthcare providers. Wearables, on the other hand, offer consistent monitoring at a fraction of the cost.
The Apple Heart Study demonstrated the potential of wearables by showing how they could detect atrial fibrillation. Similarly, wearable data has been used to predict regional COVID-19 outbreaks by analyzing factors like pulse, physical activity, sleep, and even weather conditions.
In practice, devices like Fitbit and wrist-worn blood pressure monitors have proven useful for improving postoperative care and managing blood pressure. While wearables excel at identifying trends in stress and metabolic responses, lab tests remain essential for validating these findings with clinical precision.
How Stress Changes Your Metabolism: Study Results
Recent research, supported by wearable device data, has revealed a strong connection between chronic stress and metabolic health issues. Chronic stress has been tied to higher blood lipid levels, reduced insulin sensitivity, and elevated glucose concentrations. These factors contribute to a 13%–27% increase in obesity and a 24% rise in diabetes cases between 1990 and 2019. Globally, hyperglycemia and obesity rank as the third and fifth leading risk factors for disease burden, respectively.
Cortisol and Metabolic Health
Cortisol, the body's main stress hormone, plays a dual role as a critical metabolic regulator. Under normal conditions, cortisol levels range from 20–250 ng/mL, but chronic stress can cause these levels to spike. Elevated cortisol has been linked to increased abdominal fat, systemic inflammation, and worsened glycemic control and blood pressure. The acute stress response activates multiple physiological systems, including the hypothalamus–pituitary–adrenal (HPA) axis, the sympatho-medullary axis (SAM), and the autonomic nervous system, all of which disrupt normal glucose metabolism.
Thanks to wearable devices, these changes can now be tracked in real-time. For example, sweat analysis has shown cortisol levels ranging from 7.9 to 141 ng/mL. In one study, participants exposed to cold pressor testing experienced a sharp cortisol spike within 10–15 minutes of ice-water exposure, followed by a gradual return to baseline levels after about 20 minutes. Such measurable shifts highlight the potential for wearable devices to provide immediate, actionable insights.
Practical Uses of Wearable Stress Monitoring
Wearable devices capable of real-time cortisol monitoring are proving to be valuable tools for both individuals and healthcare providers. These devices are especially helpful for people in high-stress professions - like military personnel, police officers, firefighters, and professional athletes - by offering instant feedback on stress responses. For instance, one study documented a 180 nM cortisol spike induced by exercise, providing athletes with important data to optimize their training and recovery.
For those managing chronic conditions, continuous cortisol tracking can identify stress-related metabolic triggers. Metabolic syndrome, which impacts 30–40% of adults over 65, is one area where stress plays a significant role. By monitoring cortisol fluctuations throughout the day, wearable devices enable users to make timely adjustments - such as modifying their diet or exercise routines - to reduce long-term health risks.
Study Results: Wearables Help Prevent Metabolic Problems
Emerging studies show the potential of continuous monitoring to prevent metabolic disorders. Lower cortisol levels have been associated with reduced rates of such conditions. One study introduced an advanced wearable patch featuring soft microfluidics and flexible electrodes. This patch uses a pseudoknot-assisted conformation-switching aptamer to achieve pH-calibrated, noninvasive sweat cortisol monitoring. It demonstrated a wide detection range (1 pM to 10 μM) with exceptional sensitivity.
The ability to track stress in real time offers significant preventive benefits. For example, individuals with high sugar consumption are 32% more likely to develop metabolic syndrome. By identifying stress-induced vulnerability periods, users can adjust their behaviors - like cutting back on unhealthy snacks - before issues escalate. Healthcare providers can also use wearable sensor data to detect sudden cortisol spikes and intervene early, potentially heading off stress-related metabolic complications.

What's Next for Wearables in Stress and Metabolic Health
The future of wearables in stress and metabolic health is shaping up to be much more advanced, with devices poised to go beyond basic cortisol tracking. These next-generation tools aim to deliver deeper health insights, setting the stage for a shift in how we approach preventive care.
Tracking More Biomarkers
Upcoming wearable devices are being designed to monitor a broader range of biomarkers simultaneously, providing a fuller picture of metabolic health. While current wearables primarily focus on cortisol, researchers are innovating sensors capable of detecting additional markers like cortisol metabolites, anti-stress hormones, and volatile organic compounds (VOCs) that indicate stress responses.
For instance, studies have shown that sweat contains multiple stress biomarkers, including benzoic acid, n-decanoic acid, benzyl alcohol, and other compounds found in sweat from the forehead and underarms. Prototypes already demonstrate the ability to track cortisol through sweat continuously over extended periods. This ability to monitor diverse metabolic markers could pave the way for more advanced health analytics.
AI-Powered Health Recommendations
Artificial intelligence is revolutionizing wearable technology, transforming these devices from simple data collectors into sophisticated health advisors. AI algorithms can interpret complex biochemical patterns, offering personalized insights and even predicting health issues before symptoms arise.
The results are already promising. For example, a study found that combining wearable data with blood biomarkers could predict insulin resistance with 76% sensitivity and 84% specificity. Among at-risk individuals - such as those who are obese or sedentary - this model achieved even higher accuracy, with 93% sensitivity and 95% adjusted specificity.
"AI now optimizes data interpretation, learning autonomously to predict nonsymptomatic events proactively... My goal is to be able to predict things that are nonsymptomatic and do it in a proactive manner rather than doing it reactively, where you're trying to always keep treating the symptoms. I want to be able to predict, using sensors, that something is coming." - Shravan Aras, PhD, Associate Director of Sensor Analysis and Smart Health Platforms, Center for Biomedical Informatics and Biostatistics, University of Arizona Health Sciences
AI doesn't just analyze data; it filters out irrelevant signals, identifies subtle patterns, and provides real-time recommendations. For example, if a wearable detects elevated cortisol levels alongside VOC patterns linked to stress, the AI could suggest interventions like breathing exercises or dietary changes to prevent metabolic disruptions.
This approach is already proving useful in clinical settings. During a 90-day trial at Ochsner Medical Center in New Orleans, an AI tool reduced the complexity of diagnostic coding by 44%, leading to faster and more accurate health assessments. Soon, these systems will integrate seamlessly into personalized intervention plans.
Benefits for Prevention and Healthy Aging
With advanced sensors and AI capabilities, future wearables will play a key role in preventive care. For example, early detection of insulin resistance through wearable devices can guide lifestyle changes to manage or even reverse conditions like diabetes, insulin resistance, and PCOS.
For those with PCOS, continuous monitoring of stress-related metabolic markers could help manage hormonal imbalances that contribute to weight gain and insulin resistance. Similarly, wearables could provide older adults with insights into how daily stress affects long-term health, helping to combat metabolic syndrome - a common issue in aging populations.
Conclusion: Better Metabolic Health Through Stress Management
The link between stress and metabolism is undeniable, and wearable devices are changing how we approach health by offering real-time insights. Unlike traditional lab tests that provide snapshots, wearables deliver continuous updates, giving a clearer picture of how stress impacts your body. Research highlights that adults in high-stress groups face a 45% greater risk of developing metabolic syndrome. Meanwhile, wearable devices boast an impressive 92% accuracy in detecting stress levels in metabolic syndrome patients by tracking metrics like ECG, galvanic skin response, body temperature, SpO2, glucose levels, and blood pressure.
By monitoring factors such as heart rate variability, skin conductance, and temperature shifts throughout the day, these devices help you identify stress triggers early. This early detection allows for timely interventions, potentially preventing the chain reaction of metabolic issues caused by chronic stress.
The value of objective data in health management cannot be overstated:
"Objective data like the information provided by a wearable can help improve your health significantly. There is a huge difference between thinking you sleep well and having actual sleep scores, for example." - Renae Thomas, MD, MPH, Lifeforce Physician
