The Connection Between the Nervous System and Anxiety

One important measure is heart rate variability (HRV).

HRV refers to variation in the intervals between individual heartbeats. It provides information about autonomic regulation and has been studied in areas including stress, cardiovascular health, and psychological states.

Dr. Chirag Jain's work focuses on the relationship between anxiety during cancer treatment and physiological signals such as HRV. His research asks whether anxiety can be identified through measurable changes in the body's response rather than relying only on what a patient reports.

His work therefore approaches anxiety as both an emotional experience and a physiological event.

Why This Matters During Cancer Treatment

The connection between the nervous system and anxiety becomes particularly relevant in cancer care.

Cancer treatment can involve diagnosis, repeated investigations, chemotherapy, radiotherapy, procedures, waiting periods, and uncertainty about outcomes. Each stage can place different demands on a person's emotional and physiological systems.

A patient may appear calm while experiencing significant internal distress.

This creates an important clinical question: Can healthcare professionals recognise anxiety while it is happening, rather than only after the patient describes it?

Dr. Chirag Jain's work in Onco-Anxiology explores this question by examining anxiety across the cancer journey and its physiological dimensions.

From Understanding the Signal to Responding to It

HRV is not simply a number that labels someone as anxious.
