"Room temperature": > The American Heritage Dictionary of the English Language identifies room temperature as around 20–22 °C (68–72 °F),[1] while the Oxford English Dictionary states that it is "conventionally taken as about 20 °C (68 °F)".[2] The ideal room temperature may vary by place and culture; studies from Nigeria show a comfortable temperature range of 26–28 °C (79–82 °F), comfortably cool 24–26 °C (75–79 °F) and comfortably warm 28–30 °C (82–86 °F).[3] Owing to variations in humidity and (likely) clothing, recommendations for summer and winter may vary; a suggested typical range for winter is 23–25.5 °C (73–78 °F), with that for summer being 20–23.5 °C (68–74 °F).[4] Some studies have suggested that thermal comfort preferences of men and women may differ significantly, with women on average preferring higher ambient temperatures.[5][6][7] > The World Health Organization in 1987 found that comfortable indoor temperatures between 18–24 °C (64–75 °F) were not associated with health risks for healthy adults with appropriate clothing, humidity, and other factors. For infants, elderly, and those with significant health problems, a minimum 20 °C (68 °F) was recommended. Temperatures lower than 16 °C (61 °F) with humidity above 65% were associated with respiratory hazards including allergies.[9][10] * https://en.wikipedia.org/wiki/Room_temperature https://en.wikipedia.org/wiki/Room_temperature
