Watch a fascinating 58-minute Royal Institution Christmas Lecture from 1998 where Professor Nancy Rothwell explores how humans and animals maintain constant body temperatures despite changing environmental conditions. Dive into the depths of the ocean to learn how sharks stay warm, venture to the Arabian desert to understand why Bedouins wear dark robes, and witness a brave assistant demonstrate human temperature regulation in an ice bath. Discover the remarkable adaptations of various creatures, from chinchillas to Arctic penguins, as they cope with extreme temperatures. Learn about the critical relationship between chemical reactions in our bodies and environmental temperature, and how these processes keep us healthy. Part of a five-lecture series examining physiological processes and body balance, this third installment offers unique insights into temperature regulation across different species and habitats.
