Temperature variations in various species have marked changes in body metabolism with higher temperatures associated with increased ageing. The observation that diets with calorie restriction are associated with species longevity are now related to the heat shock genes and body temperature regulation. Temperature increases that induce temperature dysregulation are connected to non alcoholic fatty liver disease (NAFLD) and the induction of diabetes and neurodegenerative diseases. Specific microRNAs are associated with heat shock gene regulation and override body temperature regulation relevant to adipose tissue-liver defects and insulin resistance. In geriatrics and diabetics complete heat shock gene inactivation is associated with mitochondrial apoptosis relevant to defective hepatic dietary fat and drug metabolism. The connections between core body temperature defects and autoimmune disease have now become important to determine programmed cell death in many cells and tissues with relevance to the global chronic disease epidemic and species survival.
