In this episode of the MSD Manual's Medical Myths Podcast, host Jason Rocker speaks with Dr. Jonette Keri, professor of dermatology and cutaneous surgery at the University of Miami Miller School of Medicine, to separate fact from fiction on the topic of sunscreen and sun protection. Dr. Keri explains the difference between mineral and chemical sunscreens, how each works, and which formulations may be better suited for certain skin types, and why broad-spectrum protection against both UVA and UVB rays is essential.

Hearing loss is common, but its effects can extend far beyond the ears. Dr. Larry Lustig, chair of Otolaryngology at Columbia University Medical Center, explains how hearing loss develops, the difference between conductive and sensorineural hearing loss, and when to seek medical attention. He also explores the connection between untreated hearing loss and brain health, including dementia, depression, and social isolation, along with advances in hearing aids, prevention strategies, and promising gene therapies for inherited hearing loss.

With hot summer days, we are excited to welcome Dr. Diane Birnbaumer, Emeritus Professor of Medicine at the David Geffen School of Medicine at UCLA, to discuss some myths about heatstroke and staying healthy in extreme temperatures.
