Thermostat Temperatures Were Designed For Men

In many homes and offices, men and women are in a constant battle over the thermostat. A 2015 paper published in the journal Nature Climate Change pointed out the reason why: the model that defined the standard thermostat temperature of 71º F (22º C) was designed in the 1960s and based on the metabolic rate of a 154 lb (70 kg), 40-year-old man. This underestimates women's metabolic rate by up to 35%, which could explain why women prefer a temperature quite a bit higher: 77º F (25º C), according to one study. The authors of the Nature paper point out that if standards were to take more genders, ages, and body types into account, the benefits would go far beyond making people comfortable. We could save energy and reduce carbon emissions, too. Explore thermostat science with the videos below.
