“…It should be noted that working memory has been found to correlate with intellectual aptitudes (and especially fluid intelligence) better than measures of short-term memory and, in fact, possibly better than measures of any other particular psychological process (Daneman, Carpenter, 1980;Kyllonen, Christal, 1990;Daneman, Merikle, 1996;Engle et al, 1999;Conway et al, 2005). The present study of single acute cold exposure agrees with the few studies that have examined the effects of repeated exposures to cold temperatures which found either no effect of cold exposure or that performance is attenuated in complex cognitive tasks, while simple tasks remain unaffected (Ellis, 1982;Ellis et al, 1985;Enander, 1987;Thomas et al, 1989;Giesbrecht, 1993).The main aim in attention tests is accuracy and fast response (reaction, i. e. motor response to a visual stimulus). Analysis of attention tests results showed a decrement of correct answers percent in both attention tests, but significant decrement was only in the attention transfer test.…”

The effect of single acute cold water exposure on the cognitive function (short-term, working memory and attention) was examined in 25 male subjects who were exposed to 14 °C cold water (air temperature ~22 °C, rh ~45%) in the semi-recumbent posture (up to the shoulders) until the rectal temperature (Tre) dropped to 35.5 °C. 6 subjects were excluded from the study, because we do not reach a necessary condition to drop their (Tre) to 35.5 °C in 170 minutes during a passive cooling procedure. During the cold exposure rectal (Tre), skin (Tsk) temperatures, heart rate (HR) were measured and cold strain (CSI) was calculated. A cognitive test battery (EFFECTON-COLD) was administrated two times (randomized): as a control measurement (CONTROL) and after the single acute cold water exposure (COLD). After COLD Tre and Tsk significantly decreased (p < 0.05). The average of HR and COLD time was 82.61 ± 4.09 and 93.68 ± 8.66, respectively. The COLD induced CSI resulted as high cold strain (7.02 ± 0.22). The present study manifested that mild hypothermia and high cold strain experienced in humans during acute cold stress, impair memory and attention tests performance in more complex tasks (tasks requiring working memory, attention concentration, sustention and speed of information processing) while simple tasks remain unaffected (tasks requiring short-term memory and attention concentration for fast response).

Cold weather can have deleterious effects on health, tolerance, and performance. This paper will review the physiological responses and external factors that impact cold tolerance and physical performance. Tolerance is defined as the ability to withstand cold stress with minimal changes in physiological strain. Physiological and pathophysiological responses to short-term (cold shock) and long-term cold water and air exposure are presented. Factors (habituation, anthropometry, sex, race, and fitness) that influence cold tolerance are also reviewed. The impact of cold exposure on physical performance, especially aerobic performance, has not been thoroughly studied. The few studies that have been done suggest that aerobic performance is degraded in cold environments. Potential physiological mechanisms (decreases in deep body and muscle temperature, cardiovascular, and metabolism) are discussed. Likewise, strength and power are also degraded during cold exposure, primarily through a decline in muscle temperature. The review also discusses the concept of thermoregulatory fatigue, a reduction in the thermal effector responses of shivering and vasoconstriction, as a result of multistressor factors, including exhaustive exercise.

Methodik zur Quantifizierung der Auswirkung von moderater Wärmebelastung auf die menschliche Leistungsfähigkeit

Ambient thermal conditions have fundamental impact on human health, well-being and working performance. Due to the increasing amount of office-related work such as in naturally ventilated buildings, the impact of moderate thermal stress to individuals becomes more and more important to be understood. Based on available empirical research, a mathematical relation has been established which, however, shows disadvantages in terms of its eligibility as building design criterion. The method of meta-analysis, which is a well-established method of psychological research, can contribute to solve this problem in terms of providing further insight into the mentioned relation. In this paper, the method of meta-analysis is introduced and its potential is shown by practical illustrations, how occupant-based data may be integrated into building simulation
