Vitals & measurements
Understanding blood pressure numbers
Learn what systolic and diastolic values represent and why
repeated measurements provide more useful context.
Systolic pressure describes the pressure in the arteries when
the heart contracts. Diastolic pressure describes pressure between
beats. Blood pressure naturally changes with activity, stress,
position and measurement technique. A single reading should not
automatically be treated as a diagnosis.
Vitals & measurements
What can affect heart rate?
Rest, activity, emotional state, temperature and other factors
can change pulse rate.
Heart rate can increase during physical activity and can also
respond to stress, illness, stimulants and environmental factors.
Resting pulse should be interpreted alongside symptoms and the
circumstances in which it was measured.
Vitals & measurements
Getting a more reliable temperature reading
Measurement site, device type, recent activity and timing can
affect temperature readings.
Follow the device manufacturer's instructions and use a
consistent measurement method when tracking changes. Fever
interpretation also depends on age, symptoms and clinical context.
Metabolic & wellness
BMI: what the number can and cannot tell you
BMI is a screening calculation based on height and weight.
BMI can be useful at a population level but does not directly
measure body composition, fat distribution or overall health.
Muscle mass and other factors can affect how the number should
be interpreted.
Metabolic & wellness
Why glucose timing matters
Fasting and post-meal glucose values are interpreted using
different reference contexts.
The timing of a glucose measurement can substantially change
its meaning. Home meters also have measurement variability.
Persistent or concerning results should be discussed with a
healthcare professional.
Metabolic & wellness
Hydration and everyday fluid needs
Fluid needs vary with environment, activity, diet and individual
circumstances.
There is no single fluid amount that applies equally to everyone.
Heat, exercise, illness and dietary intake can change hydration
needs. Medical conditions can also require individualized guidance.
Monitoring & prevention
How to keep a useful vital log
Consistent dates, times, units and circumstances make personal
records easier to understand.
Record the measurement, date and approximate time. For readings
such as blood pressure, consistency in posture and measurement
technique can make trends easier to review with a clinician.
Monitoring & prevention
Home measurements versus clinical tests
Home devices can be useful for monitoring, but they are not
identical to clinical testing.
Device quality, calibration, technique and environmental
conditions can affect home measurements. Clinicians may also
use laboratory tests or repeated measurements when evaluating
a health concern.
Monitoring & prevention
When a reading deserves attention
Persistent unusual measurements, rapid changes and symptoms
can warrant professional assessment.
Seek appropriate medical care when a measurement is persistently
concerning, when a device repeatedly reports unusual values or
when symptoms accompany a reading. Emergency symptoms require
urgent local medical services.
