ABOUT TYLER
I created the framework I needed for myself.

Functional Medicine & Stress Regulation Coach
Author of the Mindful Guide series
After a prolonged period of stress began affecting my health, I did what many people do: I had the standard tests done. Everything came back normal. But “normal” didn’t explain how I felt.
That experience deepened my interest in mindfulness and stress regulation, and led me into functional medicine, where I began to understand how profoundly sustained stress can influence systems throughout the body.
I learned how symptoms, lifestyle and biomarkers can reveal patterns that standard testing alone may miss. Over time, those insights became the basis of the Stress Signature framework.
Today, I use that framework to help people decode what their body is telling them, recognise the patterns beneath their symptoms and turn that understanding into clear, practical priorities.
Why Mindful Guide?
Mindfulness was one of the first tools that helped me understand my own relationship with stress. It showed me that health is not only about what happens in the body, but also about how we respond to the demands placed on it.
That idea became the foundation of the Mindful Guide books and, later, Mindful Guide Health: practical guidance that brings together awareness, behaviour and modern health science in a way that can actually be applied to everyday life.
Timeless pillars. Personal by design.
Health is built on interconnected systems. At the base is the nervous system. When it is under sustained stress, the effects can ripple through sleep and circadian rhythm, hormonal signalling, metabolism, digestion and immune function.
Many of the pillars of health are timeless: sleep, movement, nourishing food, light, connection and recovery. Modern science helps us understand how these pillars interact, where individual needs differ, and which levers matter most for each person.
The goal is not to optimise everything at once. It is to regulate what is under strain, strengthen the pillars that need support, and create the conditions for the body to move back towards balance.
A broader view of health
My work draws on training across several areas that often overlap in real life rather than existing in isolation.
Functional medicine
Stress regulation and mindfulness
Gut health and the microbiome
Women’s hormone health
Nutrition and lifestyle health
Biomarkers and personalised health patterns
From patterns to priorities
The Stress Signature framework grew out of a simple problem: symptoms can look disconnected even when they are part of the same underlying pattern.
The framework helps bring those signals together, identify which systems may be under the greatest strain, and make it easier to decide what deserves attention first.
It is not a diagnosis. It is a way of creating context, reducing guesswork and turning complexity into a clearer starting point.
Decode. Regulate. Restore.
Decode the pattern behind how you feel and what may be driving it.
Regulate the systems under strain with the lifestyle changes most relevant to your pattern, while reducing the demands that keep them under pressure.
Restore your capacity for steadier energy, stronger recovery and greater resilience by creating the conditions that support your body’s natural ability to recover and restore balance.
A clearer starting point begins with understanding the pattern.
The free Self-Scan identifies your primary and secondary Stress Signatures and helps show which systems may need the most support.
