Dr. Joshua Zeichner, an associate professor of dermatology at the Mount Sinai Hospital, was questioned of the potential reasons for the appearance of the red marks. Speaking to Business Insider, he explained, “Rashes on the hands can be caused by a variety of factors, ranging from infections to inflammatory conditions to external exposures.”
Of course, he added that it is not possible to diagnose a skin ailment from a single photo.
Further, Zeichner offered four explanations for Trump’s hand rashes, most of which are certainly less intriguing than the theories floating around the internet.
His hands are too dry?
One of the reasons for Trump’s red marks could be that his hands are too dry. The former president once revealed he’s been a “germophobe,” so this hypothesis of him likely washing his hands too often and making them dry may hold merit. Dry hands may also be a result of cold weather.
Golf-related blisters?
Being a passionate golf player, Trump spends time at the golf court and enjoys the game, so according to Dr. Zeicher, the red marks may result from “friction from activities like golf, weightlifting, or baseball.”
