Praise for Everything I Know About Cortisol

Hannah is my most trusted advisor when it comes to hormones – in particular cortisol – so when she shared she was writing a book on the topic, I knew it would become my stress-management manual. Reading Hannah's words is like having your hand held by your most switched-on friend.

Melanie Macleod, HELLO!

Cortisol has been blamed for everything from mood swings to belly fat, and the wellness industry has made a fortune from your fear. Here, nutritionist and hormone specialist Hannah Alderson explains why the science tells a very different story, and why the hormone you have been fearing might be the one worth listening to.

Translating complex science into practical, digestible chapters, the book will change the way you think about stress, hormones and your nervous system.
