paragraph_text: Function of clothing
  
  Serious books on clothing and its functions appear from the nineteenth century as European colonial powers interacted with new environments such as tropical ones in Asia. Some scientific research into the multiple functions of clothing in the first half of the twentieth century, with publications such as J.C. Flügel 's Psychology of Clothes in 1930, and Newburgh's seminal Physiology of Heat Regulation and The Science of Clothing in 1949. By 1968, the field of Environmental Physiology had advanced and expanded significantly, but the science of clothing in relation to environmental physiology had changed little. There has since been considerable research, and the knowledge base has grown significantly, but the main concepts remain unchanged, and indeed, Newburgh's book continues to be cited by contemporary authors, including those attempting to develop thermoregulatory models of clothing development.
