EE: Room Conditions (2013)

• Assessment
  What are the room conditions (in terms of humidity, lighting and noise) required for RMR measurement in healthy and non-critically ill individuals?

  • Conclusion

    There were no studies identified to address room conditions (such as humidity, lighting and noise) required for RMR measurement in healthy and non-critically ill individuals.

  What are the room conditions (in terms of temperature) required for RMR measurement in healthy and non-critically ill individuals?

  • Conclusion

    Decreased room temperature (less than 20°C or 68°F) has been shown to increase resting metabolic rate (RMR) in healthy adults, relative to a room temperature of approximately 22° to 25°C or 72° to 77°F. The use of a blanket minimized this increase. Seasonality has also been shown to have an effect on RMR, with cold indoor room temperature resulting in greater increases in energy expenditure during the winter compared to the summer. No studies were found that evaluated the effect of increased room temperature (more than 25°C or 77°F) on RMR. Further research is needed to better define the thermoneutral room temperature range and to examine the effect of increased room temperature on RMR in the healthy and non-critically ill.
