Linda Geddes is a Bristol-based journalist writing about the science of birth, death and everything in-between. Her first book, Bumpology, dealt with the birth part; her second, Chasing The Sun, explores the impact of sunlight on our bodies and minds. During her research, she spent a long weekend yard-sale shopping with the Old Order Amish, endured the Polar Night with the surprisingly cheerful residents of Arctic Norway, and stayed awake with bipolar patients on a Milanese psychiatric ward. She also persuaded her family to go cold turkey on artificial light to explore the impact on their sleep and well-being. Linda has a degree in cell biology and lives in Bristol.
