Objectives
- Understand circadian regulation as a fundamental health control system
- Recognise early signals of circadian dysregulation and temporal ageing
- Interpret sleep, metabolic, and blood pressure changes as circadian markers
- Apply chronotype and temporal pattern recognition to clinical practice
Pre-requisites
Completion of the Certificate in Anti-Ageing & Longevity Medicine or equivalent foundational training in longevity medicine principles.
Learners should have a working understanding of biological ageing mechanisms and systems-based clinical thinking.
Who Is It For
This module is designed for healthcare professionals seeking to expand their understanding of ageing medicine:
Development Outcomes
Course Aims & Objectives:
- Maintenance and development of knowledge and skill within your field of practice
- Expand assessment options for patients with circadian and sleep-related ageing patterns
- Integrate temporal assessment into existing clinical frameworks
In ageing medicine, circadian disruption is understood as a loss of temporal regulation, contributing to accelerated ageing, reduced resilience, and increased disease risk long before pathology is diagnosed.
1. The Circadian Regulatory System
Circadian regulation is governed by:
- The central circadian clock (suprachiasmatic nucleus)
- Peripheral clocks in metabolic, immune, and vascular tissues
- Light–dark signalling
- Timing of sleep, feeding, and activity
- Interaction with stress and autonomic regulation
This system ensures synchronisation between internal physiology and the external environment.
2. How Circadian Regulation Changes With Age
With advancing age:
- Circadian rhythm amplitude reduces
- Phase shifts become more common
- Synchronisation between central and peripheral clocks weakens
- Hormonal and metabolic rhythms flatten
- Recovery from circadian disruption slows
These changes reflect loss of temporal coordination, not simply poor sleep habits.
3. Early Clinical Signals of Circadian Ageing
Before formal diagnoses of sleep disorder or metabolic disease, clinicians may observe:
- Non-restorative or fragmented sleep
- Daytime fatigue despite adequate sleep duration
- Blood pressure non-dipping (failure to drop overnight)
- Cognitive variability across the day
- Mood instability or irritability linked to time of day
These are interpreted as early circadian ageing signals, not isolated symptoms.
4. Phenotype Connections
Certain phenotype patterns are commonly associated with circadian strain:
5. Systems Interpretation (Not Treatment)
Learners are trained to ask:
→Is circadian misalignment the driver or a symptom of other dysfunction?
→Is the pattern acute or chronic?
→Are overlapping metabolic, inflammatory, or vascular signals present?
6. Boundaries & Professional Scope
This topic does not teach:
- ✗Sleep medicine protocols
- ✗Light therapy prescriptions
- ✗Melatonin or pharmaceutical interventions
It focuses on understanding circadian ageing as a regulatory process.
