*Les Syndromes secs* examines dry mouth and dry eye syndromes in accessible, practical terms. Bernard Montain explains the role of saliva and tears in everyday comfort, explores common causes of persistent dryness, and considers how these symptoms may reflect broader imbalances in the body. Written for general readers rather than specialists, the book connects health education with practical guidance on prevention, self-care, and when professional medical attention may be needed. Its focus is on helping readers recognize and understand symptoms that are often dismissed or misunderstood, while offering a holistic perspective on hydration, bodily secretions, and quality of life.
