Room temperature is a common term to denote a certain temperature within enclosed space at which humans are accustomed. Room temperature is thus often indicated by general human comfort, with the common range of 7°C (44°F) to 32°C (90 °F),[citation needed] though climate may acclimatize people to higher or lower temperatures.
The term can also refer to a temperature of food to be consumed, which is placed in such a room for a given time. Furthermore, it may refer to a certain temperature within settings of scientific experiments and calculations.
For human comfort, desirable room temperature greatly depends on individual needs and various other factors. According to the West Midlands Public Health Observatory, 21 °C (73 °F) is the recommended living room temperature, whereas 18 °C (64.4 °F) is the recommended bedroom temperature. A study carried out at the Uppsala University, on indoor air quality and subjective indoor air quality (SIAQ) in primary schools, states that perception of high room temperature was related to a poor climate of cooperation. To achieve a good SIAQ, it recommends room temperature should be at a maximum of 31.0 °C (92.6 °F).
