Participants will be recruited through Swiss Universities and Swiss Universities of Applied Science. The institutions host a broad range of students that are likely to match the inclusion criteria.
Exclusion Criteria:
Age of the participants is between 18-40 years, females and males equally distributed
Other: Elevated ambient heat · Other: Elevated relative humidity · Other: Exertion
Temporary exposure to increased ambient temperature +10°C (the effect of the intervention is fully and spontaneously reversible)
Temporary exposure to increased ambient relative humidity +40% (max. 90%) (the effect of the intervention is fully and spontaneously reversible)
Temporary exertion on an ergometer (1W/kg body weight) (the effect of the intervention is fully and spontaneously reversible)
The within and between subject heat strain marker variability in relation to specific heat stress sources (ambient heat, ambient humidity, exertion, and clothing)
The primary endpoint is the within- and between- subject heat strain marker variability of HR, CBT, WSR, and LSR in relation to various heat stress sources (increased ambient temperature, increased relative humidity, and exertion, all without and with additional clothing.
Time frame: Max. 7 days
Accuracy to detect the specific heat stress source (such as ambient heat, relative humidity) from different on- and in-body measurements
The models for the primary endpoints will be extended to explore the relationships between heat strain parameters, heat stress sources, as well as personal characteristics. Additionally, prediction of heat stress source will be explored.
Time frame: Max. 7 days
Assessment of short-term heart rate variability in context to each heat stressor.
Short-term HRV with a repeating time frame of 5min. Root mean square of successive RR interval (RMSSD; in \[ms\]) and the Standard-deviation of RR intervals (SDRR; in \[ms\]) will be computed with respect to each heat stress source.
Time frame: Max. 7 days
Temperature [°C] and relative humidity [%] of the microenvironment as an additional source of information for patterns to detect heat stressors
Features of temperature \[°C\] and relative humidity \[%\] of the microenvironment as additional model predictors.
Time frame: Max. 7 days
The relation between cognitive assessment and skin temperature
Correlation between subjective heat comfort (Visual Analog Scale, where +1 is comfortable and +4 is very uncomfortable) and baseline differential stress inventory (causes of stress, symptoms of stress, coping, stress stabilization) in relation to skin temperature \[°C\]
Time frame: Max. 7 days
The relation between STROOP assessment and different heat stressors
Correlation between changes in the STROOP assessment outcome (number of errors and time of decision \[ms\], between beginning and end of heat stress exposure) in context to the various heat stress sources, skin temperature, and thermal comfort.
Time frame: Max. 7 days
Novel Sweat Biomarkers for heat stress detection
Descriptive statistics for novel non-invasive biomarkers from sweat analysis with respect to heat stress source, including between- and within-subject variability
Time frame: Max. 7 days
Recording heat strain parameters with an all-for-one device
The 'reliability' (missing data per minute (\[%\]) and the 'accuracy' (HR \[bpm\] with 95% confidence intervals), CBT (in \[°C\] with 95% confidence intervals), and local sweat rate measurements (in \[g/h\] with 95% confidence intervals) of the wearable device in recording vital parameters.
Time frame: Max. 7 days
