Scientific Support for Nudity

Borrowed from a post in one of my groups, but I thought it deserved a wider audience.
Parts of the UK are currently experiencing a short heatwave. A news programme on BBC Radio 4 asked a Professor of Human Physiology for advice on keeping cool. Amongst other things, he said people should wear as little clothing as possible, preferably none. The interviewer asked if he was really recommending that people should be naked, to which he replied, "Of course. After all, we were designed to be naked. We should wear clothes only when necessary."
