This week, Dr. Kahn breaks down new research on erectile dysfunction (ED) as an early warning sign—a "canary in the coal mine"—for heart disease and cardiovascular events, including mortality. He also discusses the emerging role of endocrine-disrupting chemicals and highlights new findings suggesting that ED medications like Viagra and Cialis may reduce all-cause mortality and potentially lower the risk of dementia.

Additional topics include the connection between sleep apnea and Parkinson's disease, how skipping breakfast may raise cholesterol levels, the impact of high-polyphenol diets on resting heart rate, tai chi for improving sleep, alternate-day fasting, updates on the Watchman device, and new approaches to treating carotid artery disease.

This week, Dr. Kahn also highlights the Echo Flask—an elegant way to make hydrogen-rich water. You can order one at echowater.com for a discount.
