Room temperature
Room temperature is the air temperature inside a room, usually measured in degrees Celsius (°C). In studies and buildings, it can be recorded with sensors, building systems, or other temperature-monitoring devices.
What it is and what is measured
Room temperature means the temperature of the air inside a room, not the temperature of a person’s body or the outdoor weather. It is usually measured in °C using devices such as data loggers, building management systems, or room temperature controls. In research, scientists may record average indoor temperature, hourly ambient temperature, or a set air-conditioning temperature.

How room temperature matters
The effect of room temperature depends on context. For sleep, the best indoor temperature varies with climate, housing, ventilation, bedding, and sleepwear. In surgery, a cooler operating room can contribute to hypothermia, which means a core body temperature below 36.0°C. During anesthesia, the body’s normal heat-control responses such as shivering and vasoconstriction are weakened, and heat can move from the core to the body’s outer parts more easily.

How it is measured and compared
Studies do not all measure room temperature the same way. Some use objective instruments like data loggers or central temperature control systems; others rely on self-report questionnaires. In the operating room, ambient temperature may be recorded hourly and then grouped into ranges such as below 21°C, 21.0 to 22.9°C, or 23°C and above. In indoor-health studies, reported temperatures can be means, maxima, minima, or a target setting.

Limitations and cautions
Room temperature does not act alone. Outdoor climate, building design, ventilation, bedding, sleepwear, age, body size, illness, and anesthesia all change how temperature affects people. Evidence can also be limited by different study designs, different measurement methods, and settings that are mostly from high-income countries, which makes it harder to generalize results to other places.

SEE THE IDEA
How room temperature is used in studies
The air temperature inside the room is the main measurement.
Sensors, control systems, data loggers, or self-report are used.
Comfort, sleep, or body heat balance may change.
Climate, housing, bedding, ventilation, and surgery change the effect.
Room air is measured by a method, then interpreted in context to understand its effect on people.
Room temperature is an environmental measurement, but its meaning changes with the situation and with the method used to record it.
