Episode 3: Physiology of the Season

In this special holiday edition of the podcast, we’ll talk to Perry Barboza of the institute of arctic biology at the university of Alaska in Fairbanks and Lisa Leon of the U.S. Army Research Institute of Environmental Medicine in Natick Massachusetts.

Dr. Barboza explains how a reindeer’s physiology allows survival under such frigid winters with so little food and Dr. Leon will look at how humans adapt to extremes of heat and cold. They will also give us some pointers on how to help Santa, Rudolph and the gang as they circumnavigate the globe.

Thanks for listening to Life Lines and thanks to the good folks at, especially “Radio Mall” and “Filmhits” who shared the Christmas music and sleigh bell sound effects we used in the show.
