Simple practices, lasting benefits

Rachel Campling

I am a Oxygen advantage functional breathing instructor, and a Physiology First leader with a qualification in children and young people's mental health.

After experiencing the benefits of breathwork in my own life, I was inspired to make these tools more accessible to to others - especially families, children and SEND communities who are often overlooked in the wellness space.

My workshops and courses are science backed, practical and adaptable, offering simple ways to bring functional breathing into daily life.

Grounded in science, guided by community

Physiology First is a wellness and education company that teaches the science of the body to improve physical and mental health.

Optimal health starts with understanding and addressing the body's foundational physiological needs, such as sleep, breathing, nutrition and exercise.

Health isn't something we "have"

It's something we have to DO.

Energy isn't something "have"

It's something we create by staying active.

We're supposed to feel like crap when we don't prioritize our health, it's a survival mechanism.

It's time to provide the next generation with education before medication, skills before pills, and the knowledge of their physiology, First.

The foundations of Physiology Flow

As an Oxygen Advantage instructor and Physiology First leader, I combine proven methods with a mission to make breathwork and exercise accessible, inclusive and practical for everyday life.
