Dr Jim Bartley, author of Healing Headaches and co-author of Breathing Matters with Tania Clifton-Smith, is an eminent Auckland ear, nose and throat specialist. He has been a major force in developing and promoting endoscopic surgical techniques in the management of sinus disease. He is an Associate Professor in the Department of Surgery at Auckland University as well as in the Department of Biomedical Engineering at AUT University. He has active research interests into the antibacterial actions of vitamin D and the effects of CPAP on nasal physiology. Healing Headaches is the essential guide to managing headaches, migraines and stress headaches, including advice on sleep, relaxation, exercise, nutrition — including the recent discovery that gluten-free diets can prevent migraine — and pain management. Breathing Matters explains the important physiological role breathing plays, and shows how good breathing patterns can dramatically improve health and wellbeing in a number of areas from asthma and migraine to heart disease and gastro-oesophageal reflux.North andSouth called it a ‘fact-filled fascinating guide for the general reader’, adding ‘and probably a lifesaver for the breathing-afflicted’.
