Olivia Arezzolo

Olivia Arezzolo is an Australian sleep expert, author, and coach. Her book Bear, Lion or Wolf explores the concept of chronotypes — the biological variations that determine whether you're a morning person, a night owl, or somewhere in between — and offers tailored strategies for optimising sleep, energy, and performance based on your individual chronotype. Arezzolo draws on sleep science and practical coaching experience to make the book immediately actionable. Available as an audiobook and in print, Bear, Lion or Wolf appeals to readers and listeners seeking personalised, science-based approaches to better sleep and more energised days.
