Your circadian rhythm is your body’s 24-hour internal clock, influencing sleep, metabolism, and energy. Disruptions can lead to health issues like poor sleep, diabetes, or cognitive decline. By monitoring key biomarkers - like melatonin, body temperature, heart rate, and cortisol - you can align daily activities with your natural rhythm for better health.
Key Biomarkers to Track:
- Melatonin: Regulates sleep-wake cycles.
- Body Temperature: Peaks during the day, drops at night.
- Heart Rate & HRV: Reflects energy and nervous system activity.
- Cortisol: Tracks stress and energy fluctuations.
Wearable devices and health apps now make it easier to monitor these markers, offering actionable insights to improve sleep, energy, and overall wellness. Start syncing with your body’s clock today.
How to Improve your Circadian Rhythm | Satchin Panda PhD
Main Circadian Biomarkers
Certain biomarkers provide insight into your body's internal rhythms, offering clues about how your biological clock operates.
Melatonin Production
Melatonin levels follow a predictable pattern, starting to rise a few hours before sleep and peaking in the early morning hours.
| Time Period | Melatonin Activity | Role |
|---|---|---|
| Evening (6–8 PM) | Production begins | Prepares the body for sleep |
| Night (2–4 AM) | Peak levels | Supports deep, restorative sleep |
| Morning (6–8 AM) | Rapid decline | Encourages wakefulness |
These melatonin shifts play a key role in sleep regulation. Alongside melatonin, your body temperature also provides clues about circadian timing.
Body Temperature Changes
Your core body temperature fluctuates about 1°F (0.5°C) over a 24-hour period:
- Peak: Around 6:00 PM (98.6°F/37°C)
- Trough: Around 4:00 AM (97.6°F/36.4°C)
These changes influence alertness and sleep. Higher temperatures during the day enhance focus and energy, while the evening drop signals it's time to wind down.
Heart rate patterns also follow a daily rhythm, aligning with these temperature shifts.
Heart Rate Patterns
Heart rate and heart rate variability (HRV) show distinct daily trends, with heart rates fluctuating by 10–20 beats per minute.
| Time Period | Heart Rate | HRV |
|---|---|---|
| Early Morning | Rises | Lower variability |
| Afternoon | Stabilizes | Moderate variability |
| Evening | Falls | Higher variability |
| Deep Sleep | Lowest rates | Consistent pattern |
Higher HRV during rest indicates better alignment with your circadian rhythm and is often linked to improved overall health.
Tracking these biomarkers can help you spot irregularities and make adjustments to maintain a healthy routine.
Wearable Devices for Tracking
Wearable technology now allows for continuous monitoring of circadian biomarkers, offering a detailed view of daily biological rhythms.
Sensor Technology
Wearable devices come equipped with various sensors to track key indicators of circadian health. Here’s a breakdown of the main sensor types:
| Sensor Type | Measurements | Technology |
|---|---|---|
| Optical (PPG) | Heart rate & HRV | LED & photodetectors |
| Temperature | Skin temperature | Thermistor |
| Accelerometer | Motion | MEMS |
Optical sensors rely on blood flow analysis to measure heart rate and heart rate variability (HRV). Temperature sensors track skin temperature, while accelerometers monitor motion to identify rest-activity cycles. Despite their advanced capabilities, these sensors have certain drawbacks.
Accuracy and Limits
Although wearables provide continuous data, their measurements are not without challenges:
- Heart rate monitoring can be disrupted by movement or physical activity.
- Skin temperature sensors don’t reflect core body temperature with complete accuracy.
- Placement and environmental factors can influence the reliability of all measurements.
While wearables are excellent for ongoing tracking, their precision doesn’t yet match that of clinical-grade equipment.

Health Apps and Data Analysis
Today's health apps take data from wearables and turn it into practical insights about your circadian rhythm. By using trusted algorithms, these apps provide accurate tracking of your body's internal clock.
Device-App Connection
Health apps connect to wearable devices through Bluetooth. This connection allows continuous data streaming, giving you near real-time updates on circadian biomarkers. With this steady flow of information, apps can provide a detailed view of your daily rhythms.
Data Integration
Once connected, advanced apps combine data from multiple sources. They integrate signals like movement, temperature, and light exposure to create a clear picture of your sleep-wake cycles and overall daily patterns.
Features to look for in circadian tracking apps include:
- Real-time trend visualization for biomarkers like heart rate, activity, and body temperature
- Custom alerts and advice to help you optimize sleep, exercise, and meal schedules
- Environmental data integration, such as light exposure, to better interpret your physiological signals
- Easy data export options for sharing detailed reports with healthcare professionals
These tools make it easier to get accurate, personalized insights that support a healthy circadian rhythm.
