Brief Summary:
Study design A cross-over single-blinded treatment design will be used Participants will undergo 4 different conditions 1 low air flow and 23C 2 low air flow and 35C 3 high air flow and 23C and 4 high air flow and 35C Participants will be blinded to the air quality level however it is not possible to blind them to the temperature condition as they will be able to perceive it as different
Study population The population consists of healthy young and middle-aged adults of both sexes between 18 and 40 years
Intervention if applicable Each participant undergoes 4 conditions in randomized order Two conditions consist of poor air quality defined as 3000 ppm carbon dioxide and 23C or 35C temperature respectively

Detailed Description:
Objective This study aims to examine the effect of indoor air quality and temperature on human cognitive performance The main research objective of this study is to examine how indoor air quality and temperature affects cognitive performance respectively As a secondary objective it will be examined if a higher temperature of 35C compared to 23C amplifies the negative effect of low air flow vs high air flow on cognitive performance It will also be examined if human perceive the air quality as less pleasant under the higher temperature even if the air quality itself does not change in terms of carbon dioxide concentration Also the physiological reaction towards poor air quality and elevated temperature will be examined in isolation and interaction
Main study parametersendpoints The main study parameters are the achieved scores of the cognition test mainly derived from the Cambridge Neuropsychological Test Automated Battery CANTAB and the Cognitive Ability Task As secondary outcome the physiological response will be examined Specifically it will be investigated how the air quality and temperature affect the following physiological parameters Capillary blood CO2 and pH level salivary cortisol and a-amylase and serum cytokine response lung function heart rate respiration rate skin temperature core temperature blood pressure physical activity and metabolic rate
Primary Objective The main research objective of this study is to examine how poor indoor air quality in terms of low air flow compared to high air flow and elevated temperature of 35C compared to 23C affect cognitive performance respectively
Secondary Objectives The following secondary objectives will be investigated in this study
1 It will be examined whether the decline in cognitive performance is greater when low air quality to high air quality compared to when temperature levels are increasing from 23C to 35C
2 It will be examined whether a higher temperature of 35C compared to 23C amplifies the negative effect of poor air quality
3 It will be examined whether participants perceive the air quality as less satisfactory if temperature levels are higher indoors even when the air quality is unchanged It will be also examined to which physiological reactions poor air quality and elevated temperature lead Specifically the following objectives will be investigated
4 It will be examined whether metabolic rate is affected under poor air quality conditions or higher temperature indicated by a change in CO2 production and oxygen consumption
5 It will be examined whether poor air quality or higher temperature levels are associated with a stress response defined by a higher heart rate higher respiration rate higher blood pressure higher alpha-amylase and cortisol levels and a higher rate of non-exercise activity thermogenesis through increased physical activity
6 It will be examined whether lung function in terms of forced expiratory volume and forced vital capacity are reduced when participants are exposed to poor air quality in combination with a higher temperature of 35C
7 It will be examined whether blood capillary carbon dioxide concentration and blood pH level are elevated under worse air quality in combination with a higher temperature of 35C
