Paul Lundgren Puts His Handprint On Training

Paul Lundgren Puts His Handprint On Training

Steven Munatones 10/07/2013 Open Water Swimming No Comment
This past week, Paul Lundgren trained 20 miles for three consecutive days in preparation for his upcoming 78-mile swim across Mexico’s Sea of Cortez.

In the process of spending hours on end, the fingers of his hands wrinkled up big-time. Why only wrinkle only on the hands and feet…and not all over?

The palms of the hands and soles of the feet have thicker skin and thicker layers of keratin than the rest of the body. This keratin helps keep the skin moist and absorb water easily. The dead keratin cells in the skin start to swell after being in the water for long periods of time. When the cells swell up, but the cell underneath do not, the temporary new surface area of the wrinkles are the result.

Which Lundgren will have after his sea crossing in the warm waters of the Sea of Cortez.
