It all started in 1933 with a paper by Howard Warren, a Princeton psychologist and president of the American Psychological Association, who spent a week at a German nudist camp a year earlier.
According to Ian Nicholson, Professor of Psychology at St. Thomas University in Fredericton, New Brunswick, Canada, in the Journal of the History of the Behavioral Sciences, Warren’s article, “Social Nudism and the Body Taboo,” “was a qualitative and largely sympathetic consideration of the social and psychological significance of nudism.”
Warren “described nudism in therapeutic terms, highlighting the ‘easy camaraderie’ and lack of ‘self-consciousness’ in the nudist park, in addition to a ‘notable improvement in general health,’” along with the principal perspective to return to nature.
Soon after, other articles were published in psychology journals that highlighted the benefits of nudism in contributing to healthy, well-adjusted kids and adults.
