Airway health is an important but often overlooked area of medicine, and studies have connected poor airway health to sleep, cognitive, behavioral, and physical problems. Dr. Shereen Lim is breaking new ground in this field with her book Breathe, Sleep, Thrive, a comprehensive guide to breathing and airway development. It covers the issues that can arise from poor airway health to what steps can be taken to prevent and reverse damage, focusing on children’s development in particular.
