It’s another edition of the Midday Healthwatch, our monthly conversations about public health with Dr. Leana Wen. As we lean into our new year’s resolutions, Dr. Wen has written about some lifestyle changes we should consider, and how to get the most out of our exercise regimens. Dr. Wen is a former health commissioner of Baltimore, a columnist on health matters for the Washington Post, a medical expert at CNN and a scholar at George Washington University and the Brookings Institution.Email us at midday@wypr.org, tweet us: @MiddayWYPR, or call us at 410-662-8780.
