Evelyn Hawthorne writes at the crossroads of physiology and everyday life, translating research in stress biology, sleep, and behaviour into language people can use before a crisis. Her work is guided by the old-new idea that capacity is stewarded, not spent. Drawing on interviews with clinicians, shift workers, founders, and carers, she offers warm authority and humane precision. When not writing, she times her coffee to the morning light and argues that a good night's sleep is a civic virtue.
