With climate change increasing seasonal temperatures and causing more frequent heatwaves, understanding these effects has become more crucial than ever. However, many of these studies involved short-term heat exposure in non-human animal models or in healthy human volunteers such as military recruits. Lead author, Professor Fadil Hannan from the Nuffield Department of Women’s & Reproductive Health at the University of Oxford, stated: 'We know very little about whether increased heat exposure due to climate change could affect endocrine health. We require research involving both the endocrine and global health research communities to assess the impact of rising temperatures and heatwaves on endocrine patients. The study, 'Endocrine effects of heat exposure and relevance to climate change,' is published in Nature Reviews Endocrinology.
