Bio Signals Lab — Health Analytics Dashboard
Visualize and understand your body's signals. Sleep quality, stress patterns, and heart rate trends — analyzed with data science for actionable health insights.
AI-Generated Health Insights
Automated analysis of your bio-signals detects patterns and provides actionable recommendations.
Your sleep quality is improving
Average sleep score: 82/100. Deep sleep percentage has increased by 12% over the past 7 days.
Stress levels are high mid-week
Peak stress detected Tuesday–Thursday. Consider mindfulness practice or physical activity on those days.
Resting heart rate is within normal range
Average resting BPM: 65. This is in the optimal range (60–70 BPM) for healthy adults.
Sleep Quality — Last 7 Days
Composite sleep score (0–100) based on duration, deep sleep %, REM %, and sleep continuity.
* Demo data. Connect a wearable device API for live data.
Stress Level Trends
Daily stress index (0–100) derived from heart rate variability and activity patterns.
Heart Rate Throughout the Day
Hourly heart rate readings (BPM). Elevated BPM after meals and exercise is expected.
Why Bio-Signal Analytics Matters for Your Health
Bio signals — electrical and physiological signals produced by the human body — carry rich information about your health. Modern wearable sensors can capture heart rate, skin conductance, temperature, and movement in real time.
By applying machine learning algorithms to this data, we can detect patterns that are invisible to manual inspection: early signs of stress, sub-optimal sleep stages, and recovery deficits.
The Open Web Lab Bio Lab demonstrates these techniques using publicly available research data and mock sensor readings. Explore the Sleep Analysis Dashboard for deeper sleep metrics, or read our guide to sleep data science.
Frequently Asked Questions
What is the Bio Lab?
Bio Lab is an interactive health-analytics dashboard that visualises bio-signals such as sleep quality, stress and heart rate trends.
Is the data shown real?
The dashboard uses illustrative sample data to demonstrate the visualisations. You can connect your own wearable export for personal numbers.
Which devices and formats are supported?
The roadmap supports common exports such as Garmin CSV, Apple Health XML and Fitbit JSON, parsed locally in your browser.
Is my health data private?
Yes. Any data you load is processed in your browser and is never uploaded to a server.
What is heart rate variability (HRV)?
HRV is the variation in time between heartbeats. Higher HRV generally indicates better recovery and autonomic balance.
What is a good sleep score?
Sleep scores combine duration, deep and REM percentages and continuity. Higher is better; consistently low scores suggest room to improve sleep habits.
Can this replace medical advice?
No. Bio Lab is for education and self-tracking only and is not a medical device or a substitute for professional advice.
Is Bio Lab free?
Yes. It is free to use with no signup required.
