Decoding Your Charts: How to Read Your Body’s Hidden Rhythms

The Complete Guide to Comprehending Your 24-Hour Physiological Data

You’ve worn your Watch2Care Vital for 24 hours. You’ve seen your Daily Health Score. But if you look deeper into the app, you’ll find something even more fascinating: the raw data charts.

To the untrained eye, these might just look like squiggly lines. But to a trained eye, they are a narrative of your day—revealing how well you slept, how your heart handled stress, and even the state of your mental health.

Most standard wearables hide this raw data from you, offering only simplified averages. We believe you deserve the full picture.

In this guide, we will teach you how to read the 5 critical charts in your daily report. Think of this as the "User Manual" for your own physiology.

 

1. The 24-Hour Heart Rate Distribution: Your Daily Energy Wave

What it is: This chart visualizes your heart rate (HR) continuously throughout the day and night. It isn't just a line; it uses a color-coded system to tell you exactly what physiological state you were in at any given moment.

The Color Code:

  • Blue: You are in an Awake State.

  • Green: You are in an Active Sleep State.

  • Red: You are in an Active State (Exercise/Movement).

  • Gray: You are in a Resting State.

  • Yellow: Indicates an Irregular Heartbeat.

 

The "Healthy" Pattern:

Ideally, you want to see a clear distinction between day and night. People with good circadian rhythms show a higher average heart rate during awakening (Blue) and a lower average heart rate during sleeping (Green), with a significant difference between the two.

 

Warning Signs to Watch For:

  • The "Cliff-Like" Drop (Paroxysmal Bradycardia):


    Look at your Green (Sleep) section. If you see the line suddenly plunge deep down—like a cliff—this is a sign of Paroxysmal Bradycardia.

    • Common Symptoms: Chest tightness, chest pain.

 

  • The "Peak-Like" Rise (Idiopathic Tachycardia):
    Look at your Blue (Awake) section. If you see sudden, sharp spikes that look like towers reaching for the top of the graph, this is Idiopathic Tachycardia.

    • Common Symptoms: Anxiety, palpitations.

 

  • The "Intersection" (Disrupted Circadian Rhythm):
    If your Awakening (Blue) line is low and your Sleeping (Green) line is high, causing them to intersect or show minimal difference, your biological clock is disrupted.

    • Common Symptoms: Unable to fall asleep while sitting or lying down.

 

  • The "Sawtooth" Sleep (Fluctuating Heart Rate):
    If your Green line fluctuates wildly up and down during the night.

    • Common Symptoms: Frequent dreaming and easy awakening.

 

2. The 24-Hour Pulse Wave Variation: Heart & Vessel Coordination

What it is: This is the most advanced chart on your watch. It plots two lines over 24 hours to show how your cardiovascular system is cooperating.

  • Blue Line: Myocardial Contractility (How hard your heart muscle is pumping).

  • Red Line: Vascular Elasticity and Peripheral Resistance (The resistance in your blood vessels).

 

Warning Signs to Watch For:

  • The "Synergistic Rise": High Viscosity
    If BOTH the Blue and Red lines rise high together, it means your heart is pumping hard and your vessels are resisting.

    • What it means: Unless you are pregnant or a rapidly growing child, this indicates High Blood Viscosity (thick blood) and ischemia (lack of blood supply) to important organs like the heart, brain, and kidneys.

 

  • The "Dispersion": Mental Stress
    If the lines become separated, messy, or show increased "dispersion", it indicates a disconnection in your cardiovascular regulation.

    • What it means: This pattern is commonly seen in states of Anxiety or Depression.

 

3. The Body Movement Distribution: Your Vitality Meter

What it is: This chart tracks your physical vitality.

  • Healthy Pattern: Individuals with strong vitality (like children) typically exhibit agile and hyperactive movements.

  • Low Vitality Pattern: Individuals with weak vitality (like the elderly) exhibit slow and reduced movements.

 

Warning Sign:

  • Decreased Physical Strength:
    If the chart shows low intensity and short duration of body movements throughout the day.

    • Common Symptoms: Fatigue, loss of appetite, emaciation (weight loss), wheezing when moving, shortness of breath, low speech, and low work efficiency.

4. The Poincaré Plot: Your Stress Map

What it is: This scatter plot looks like a cloud of dots. It measures your Heart Rate Variability (HRV).

  • Healthy Pattern: The dots should be distributed near the midpoint of the diagonal line. The cloud should be long, wide, and have a large area.

 

The "Drift" Patterns:

When your nervous system is out of balance, the "cloud" drifts to one corner.

  • Lower Left Drift: The "Anxiety" Pattern (Sympathetic Excitation)

If your cloud shrinks and moves toward the bottom left corner, your Sympathetic Nervous System is in overdrive.

    • Mild Symptoms: Dry mouth, fast heartbeat, sweating, loss of appetite, insomnia, and feeling "on edge".

    • Severe Symptoms: Head swelling/pain, redness in face/eyes, ringing in ears (tinnitus), cold sweat on hands/feet, irritability, and restlessness.

 

  • Upper Right Drift: The "Depression" Pattern (Parasympathetic Excitation)
    If your cloud moves toward the top right corner, your Parasympathetic Nervous System is over-dominant.

    • Mild Symptoms: Drooling, slow heart rate, low interest in activities, feeling melancholy, few words or movements.

    • Severe Symptoms: Grief/desire to cry, inferiority/self-blame, suspicion/overthinking, social withdrawal, or even suicidal thoughts.

     

 

5. The Respiratory Poincaré Plot: Your Breath Quality

What it is: Similar to the heart rate plot, this visualizes the rhythm of your breathing cycle-by-cycle.

  • Healthy Pattern: The points should be distributed near the midpoint, appearing long, wide, continuous, and regular in shape.

 

Warning Signs to Watch For:

  • The "Irregular" Cloud (Obstructed Tract):
    If the dots are scattered without a clear shape, it indicates an obstructed respiratory tract.

    • Symptoms: Inspiratory dyspnea (difficulty breathing in) or expiratory dyspnea (difficulty breathing out).

 

  • The "Discontinuous" Cloud (Lack of Coordination):
    If the cloud is split into separate islands of dots (discontinuous), it indicates a lack of coordination in your respiratory center.

    • Symptoms: Apnea (breathing pauses), alternating deep and shallow breathing, or irregular "sigh-like" breathing.
