Mitochondria

If you've ever felt exhausted and wondered what your body is doing - this book is for you.

Mitochondria are mentioned everywhere now: fatigue, ageing, illness, longevity, "energy optimisation." But most people are given a label, not an explanation.

In Mitochondria: Energy, Illness, and Why So Many People Feel Depleted, James Barrett explains what mitochondria actually are and how energy really works in the human body - in plain language, with calm authority, and without selling you a protocol.

This is not a biohacking guide.
It's not a supplement plan.
It's not a promise.

It's a clear, humane map of why energy changes - especially after stress, illness, inflammation, and long periods of pressure.

Inside, you'll discover:

a simple, readable explanation of what mitochondria do

why energy drops even when you're "doing everything right"

how fatigue can be protective, not defective

why chronic stress and constant alertness are metabolically expensive

the hidden trap of optimisation culture

what actually supports mitochondria: nourishment, movement, rest, circulation, and safety - without targets or obsession

If you want a steady, intelligent explanation that helps you understand your body without turning your life into a project, this book will meet you there.
