In this episode of The Brain Architects, Lindsey Burghardt, MD, MPH, FAAP, moderates a conversation with Alison Lee, MD, MS, and Joseph Allen, DSc, MPH, on how air quality during pregnancy and early childhood impacts lifelong health and development. The discussion has a special focus on indoor air, where we spend more than 90% of our time. They cover science-informed, practical strategies to improve indoor air, from adopting pollutant-free products and ventilation systems to advancing policy changes and building designs that prioritize health. They also offer resources for taking action in your community to ensure children and their caregivers have cleaner air to breathe.
