Health effects of dancing naked in cold, with hat

ANN ARBOR, Mich. (AP) — Anyone who's ever wondered how much good it does to wear a winter hat while venturing outside in the cold without clothes has a possible answer to that question, thanks to a new series of humor-laden videos being released by the University of Michigan's School of Public Health.

Andrew Maynard developed the Risk Bites series, available on YouTube. He is director of the university's Risk Science Center and a professor of environmental health sciences.

Maynard says he wants the series to give people credible and timely information on understanding human health risks.

In the videos, Maynard uses a white dry erase board and a black marker to draw lessons on topics like gun control, the plastics chemical BPA and the amino acid tryptophan.
