Technology in Pregnancy and How Wearable Health Trackers Can Help

Key Health Metrics Monitored by Wearables

Modern wearable devices have become invaluable for tracking several health metrics, especially during pregnancy. These devices provide insights into both physical and emotional health, helping expectant mothers make informed decisions throughout this transformative time. One of the most critical areas of focus is heart rate data, which can reveal early signs of potential issues.

Heart Rate and Heart Rate Variability

Heart rate and heart rate variability (HRV) are two essential metrics wearable devices can monitor during pregnancy. HRV measures the time intervals between heartbeats, offering a glimpse into how well the autonomic nervous system is managing stress.

During pregnancy, heart rate typically increases after conception, peaks around two weeks later, briefly dips, and then rises again until just before delivery. Meanwhile, HRV tends to decline until about 33 weeks of pregnancy before beginning to recover.

A study conducted by WHOOP Inc. between March 2021 and October 2022 analyzed data from 241 participants across 42 U.S. states and 16 other countries. The findings showed that maternal HRV decreases during pregnancy until about 33 weeks, after which it starts to rise. Importantly, the study also discovered that changes in nighttime HRV could act as a digital biomarker for detecting the risk of preterm delivery.¹

This is particularly critical given that the U.S. singleton preterm birth rate is 8.42%². By spotting early shifts in HRV, healthcare providers can identify mothers who may need further evaluation or interventions, such as progesterone treatments to delay labor or corticosteroids to support fetal development.

Sleep Quality and Sleep Patterns

Sleep often becomes more challenging as pregnancy progresses, making sleep tracking one of the most beneficial features of wearables. Approximately 80% of pregnant women experience sleep disturbances, which can have serious health consequences for both mother and baby.

Wearable devices monitor metrics like total sleep time, sleep stages, deep sleep, and periods of wakefulness. This data is vital because poor sleep during pregnancy has been linked to risks like preeclampsia, gestational diabetes, prolonged labor, and higher rates of cesarean sections.³

As Jodi A. Mindell, PhD, a psychology professor at St. Joseph's University, explains:

Thanks to surging hormones, sleep disturbances may begin right at the start of pregnancy.

By tracking sleep patterns, wearables help expectant mothers identify issues and make adjustments. For example, they can pinpoint whether you’re getting enough deep sleep or identify factors disrupting your rest. This information can guide changes to bedtime routines or sleep environments to improve overall rest.

Physical Activity and Movement Tracking

Monitoring physical activity during pregnancy is just as important as tracking heart and sleep data. Staying active benefits both the mother and baby, but it’s essential to do so safely. Wearables make this easier by tracking steps, distance, calories burned, and exercise intensity.

These devices provide insights into daily movement patterns and how activity levels shift throughout pregnancy. Many wearables even offer pregnancy-specific recommendations, like reminders to move after long periods of inactivity, which can help improve circulation and overall health.

By keeping an eye on activity data, mothers-to-be can identify the best times to exercise and adjust their routines based on energy levels and how their body responds.

Stress Monitoring and Mental Health Insights

Stress management is another area where wearables shine. Devices equipped with EDA (electrodermal activity) sensors can measure stress levels by tracking changes in heart rate and respiratory rate. Research shows that stress can increase heart rate by an average of 1.40 bpm and respiratory rate by 0.20 breaths per minute.⁴

A study by Jang et al. introduced a graphene e-tattoo (GET) system capable of delivering high-fidelity EDA signals while minimizing motion-related interference. This system performed consistently during various activities over a 15-hour period and closely matched the accuracy of traditional EDA sensors.⁵

Many wearables also offer tools like guided breathing exercises and meditation prompts to help manage stress in real time. These features empower expectant mothers to take proactive steps to support their mental well-being.

Advanced Metrics: Blood Pressure, Glucose, and Contraction Tracking

Some advanced wearables go even further, monitoring blood pressure, glucose levels, and contractions. Blood pressure tracking is particularly helpful for identifying conditions like pregnancy-induced hypertension or preeclampsia. Real-time data analysis, often powered by AI, can alert users and healthcare providers to potential complications early on.

For women with gestational diabetes, certain wearables can integrate with continuous glucose monitors to track blood sugar levels throughout the day. This helps identify how diet, activity, and stress impact glucose control.

Specialized pregnancy wearables may also include contraction tracking, which monitors the frequency, duration, and intensity of contractions as delivery approaches. By integrating these advanced metrics with healthcare systems, providers can offer more personalized care and address potential issues before they escalate into serious complications.

Benefits of Wearable Health Trackers for Expecting Mothers

Wearable health trackers go beyond simply collecting data - they provide expecting mothers with practical insights, timely warnings, and tailored guidance to support both their health and that of their baby. These tools can make the journey through pregnancy safer and more reassuring.

Early Detection of Potential Health Complications

One of the standout advantages of wearable devices is their ability to establish individual baselines for vital signs and detect any deviations that might indicate complications. This kind of continuous monitoring can catch subtle changes that might otherwise go unnoticed. For example, research has shown that wearables can identify significant differences in heart and breathing rates between pregnant women with and without intraamniotic infection⁶. This means potential issues can be flagged in real time, prompting early consultations with healthcare providers - an especially valuable feature for high-risk pregnancies. Studies even suggest that wearables can often predict acute illnesses faster than relying on symptom reporting alone.⁷

Personalized Feedback for Energy, Nutrition, and Sleep

Wearables also offer practical, day-to-day guidance tailored to the needs of pregnant women. For instance, smartwatches can remind users to stay hydrated, helping them meet the recommended 8–12 glasses of water per day - a critical need during pregnancy, as blood volume can increase by as much as 50%. These devices also analyze sleep patterns, identifying issues like insomnia or sleep apnea and suggesting adjustments to improve rest. Additionally, by tracking metrics such as heart rate and blood pressure, wearables can help women recognize when to slow down and set realistic activity goals. A study in the Journal of Medical Internet Research highlighted how wearables significantly improved maternal health outcomes by enabling better monitoring and early detection of potential problems.⁸

Building Maternal Confidence and Peace of Mind

For many expecting mothers, pregnancy comes with a fair share of anxiety. Wearables help alleviate this by providing real-time health insights. By establishing a personalized health baseline, these devices allow women and their healthcare providers to distinguish between normal pregnancy changes and potential concerns. Many women report feeling more in control and less stressed when using wearables, as the data shifts their focus from vague worries to clear, actionable information.

Healthcare professionals also see the psychological benefits. Jenna Wallace, a pediatric psychologist at WVU, explains:

The data we are gathering can help obstetricians to encourage and guide their pregnant patients and also to provide peace of mind to female athletes who prioritize the well-being of their babies during this important stage of life.

This real-time information empowers women to take an active role in their prenatal care, fostering confidence and enabling early interventions if needed.
