Scientists Uncover a Surprising Connection Between Appetite and Sun Exposure
Recent studies from Tel Aviv University show that women are not affected by sun exposure on their hunger levels, but males are. The study shows how the metabolic pathway is engaged differently in men and women. It was carried out utilizing lab models. Males of both animal and human species, as well as those exposed to the sun, are reportedly triggered to produce a protein called p53 that repairs any DNA damage that may have been done to the skin as a result of the exposure. The body produces the hunger-inducing hormone ghrelin in response to p53 activation. In females, the hormone estrogen stops p53 from interacting with ghrelin, preventing the desire to eat after being in the sun. The ground-breaking investigation was directed by professor Carmit Levy and Ph.D. candidate Shivang Parikh of the Department of Human Genetics and Biochemistry at TAU's Sackler Faculty of Medicine. In addition to the Tel Aviv Sourasky (Ichilov), Assuta, Meir, and Sheba Medical Centers, Drs. Yiftach Gepne...
