How Do Temperature And Humidity Affect Executive Function
The impact of office noise on performance has recently been the topic of much debate. Several studies have tried to measure the effect of sound on office operation, but no consensus has been reached. Studies have tried to check the impact of ambient noise on degrees of fatigue and alertness, however, the results are combined. A range of investigators report that the results are consistent across a high number of categories, but conclusions are frequently controversial. A special laboratory test (EQ-i) was designed for the experimental evaluation of office sound. The test has proven to be a trusted tool for measuring the effect of sound on workplace productivity.
The EQ-i is based on two elements. 1 part measures the cognitive processing of workplace employees, while the other component measures the subjective reaction of office employees to different visual stimuli. The testing procedure is carried out in a quiet room with the noise of a personal computer turned off. A battery of tests is performed on a specific group of office employees. A subjective questionnaire is also carried out on each person to receive information in their working habits and feelings concerning the office environment. After a series of tests are conducted on a random sample of workplace personnel, a mean total score is calculated for every individual.
Several other explanations have been advanced to account for the results of the EQ-i results. Possible explanations are that office employees were not exposed to sufficient substantial intensity or low intensity sound during the testing interval, workplace equipment was malfunctioning or inaccurate, or the results were skewed due to several confounding factors. No alternative explanation has yet to be provided that can explain the results obtained from this test.
An evaluation study was conducted to ascertain the association between ambient temperature and indoor lighting at a medical setting. Researchers measured indoor lighting at four different points in the office area and found a strong and significant relationship between the two. The researchers attributed this connection to the impact of light on worker's moods. Indoor temperature was shown to be negatively associated with the mood of office employees as evidenced by a statistically significant increase in anxiety levels. The authors concluded that"the present review... suggests that there is a negative relationship between ambient temperature and mood among office workers."
In another study, researchers examined the impact of red vs. blue light on neurobehavioral testing. They quantified neurobehavioral testing at a dimly-lit room and found no real difference in performance between conditions. However, the researchers stressed the importance of using an appropriate neurobehavioral testing protocol and executing standardized psychological evaluations in clinical settings. They also highlighted that more studies must be done to examine the impact of reduced illumination on neurobehavioral testing.
A third research project attempted to measure the effect of temperature on reaction time in a laboratory setting. Researchers measured reaction time at a dimly-lit space and discovered that the response time increased when there was an increase in room temperature. But they worried that this wasn't a significant effect and was affected by the existence of different aspects. By way of example, a slight increase in temperature diminished the amount of beta action. What's more, the researchers emphasized that the impact of temperature on the reaction time could have significant implications for executive function evaluation.
The fourth research project tested the impact of temperature on executive function in an environment with two different light-sensitivity levels (daylight or dark). Two office workers, one with a day/night preference and another with a no-light preference, engaged in a job where their performance was tested using a reaction time paradigm. After completing the task, the performance of both office workers was compared. The results showed a significant main effect of temperature on the response time (p = 0.049). The authors concluded,"A different window of temperature advantage may contribute to executive processing rate " This study demonstrated that fever did really have a positive impact on reaction time as it was controlled for ambient lightness or darkness.
In general, these studies confirm the significance of fever for work performance. Specifically, they show that fever can modulate multiple areas of performance such as attention, mood, alertness, and mental functioning. Office employees are particularly susceptible to temperature changes, which is probably due to the inherently challenging nature of the work that involves sitting in front of a monitor or working with extreme lighting conditions.
