The Bigger Picture of Human Health
• Your body and mind (and symbiotic organisms) versus the
world
• The world is stressful

The Bigger Picture of Human Health
• Adaptive biological organisms
• Health issues occur when:
• Acute stress exceeds chronic adaptation
• or
• A strong/chronic mismatch between our genes and our
environment

Why Heart Rate Variability (HRV)?
HRV can non-invasively measure the body’s response to
stress, and with enough data, its capacity to tolerate stress.
• Systemic, big picture metric
• Was expensive, now cheap and accessible
• Short, frequent measurements open new doors

HRV 101
• Temporal variation in heart beats
• Requires high degree of accuracy
• Many algorithms/calculations

HRV 101 – Autonomic Nervous System
● Controls stimulation of
“rest-and-digest” activities
essential for recovery
● Needed for long term
survival
● Controls stimulation of
“fight-or-flight” stress
response
● Needed for short term
survival
● Associated with stress
SympatheticNervous System (SNS)
ParasympatheticNervous System (PSNS)

HRV In The Research
• Decades of research
• 20,000+ studies in PubMed
• Increasing rapidly
• Still a lot to learn

Even the pre-diabetic stage, where individuals have impaired glucose
tolerance, is associated with lower HRV and decreased Parasympathetic
activity. It is believed that Parasympathetic modulation may decline with
an autonomic imbalance during the progression “from normal glucose
tolerance to impaired glucose tolerance and finally diabetes”.

Patients with HRV (SDNN) values above 100 showed a
significantly higher survival rate. Survival rates declined as
the Heart Rate Variability SDNN value decreased.

In osteopathic manual therapy, (as measured by HRV) a greater
parasympathetic response was found when stimulation was
performed in the cervical and lumbar regions, whereas a greater
sympathetic response was found when stimulation was
performed in the thoracic region.
