Temperature

A cold environment provides a favorable starting point for the temperature decrease required for sleep. A one degree Celsius lower average body temperature is estimated to correspond to about nine additional years of average lifespan when LE0 is 75 years under healthy cold conditions. The Gompertz function lacks an explicit temperature term despite evidence that temperature affects lifespan. A cold room supports sleep better than a warm room. The needed temperature decrease for sleep is slightly less than one degree Celsius. The needed temperature decrease for sleep is approximately two to two and a half degrees Fahrenheit. Temperature showed no correlation with COVID-19 surge patterns across European regions. Published Drosophila and Calliphora stygia datasets supported the predicted linear relationship between ln(LE0/T) and 1/T. Early Drosophila experiments suggested that ambient temperature changes lifespan and that the temperature coefficient resembles a chemical reaction coefficient. The derived temperature relationship predicts that ln(LE0/T) is linear with 1/T. Temperature enters the model through the Arrhenius temperature dependence of the vital-unit shortening rate b. Env…
