Outcome measures
Primary outcome
1. The intention of thermoregulatory behavior, using a questionnaire;
2. Energy expenditure, as measured using indirect calorimetry in a climate controlled respiration chamber.
Secondary outcome
1. Thermal comfort, using a questionnaire with a VAS;
2. Thermal sensation, using a questionnaire with a VAS;
3. Thermal environment, using a questionnaire with a VAS;
4. Skin temperature, using iButtons;
5. Core temperature, using an ingestible pill;
6. Skin perfusion, using Laser Doppler Flowmetry;
7. Blood parameters.
Background summary
The volunteers will be measured at home and in an experimental setting where they will be exposed to heat and cold during three different trails. This will be done in order to study the effect of physiological parameters on thermoregulatory behavior, and on thermal comfort and sensation.
Study objective
The intention to change behavior is related to changes in multiple physiological variables. Thermal comfort and thermal sensation are related to these physiological parameters. Furthermore, the intention of behavior is related to changes in thermal comfort and thermal sensation.
Study design
Participants will be instructed for a 24-hour measurement at home (1 hour) and will visit the research facility three times for 3.5 hour.
Intervention
Cold and heat exposure during three trials:
1. Protocol A is composed of a neutral-to-warm transition in ambient temperature (24°C to 32°C, with 4 K/h);
2. Protocol B is composed of a neutral-to-cold transition in ambient temperature (24°C to 16°C, with 4 K/h);
3. During protocol C ambient temperature will be varied between three fixed temperatures (16°C, 24°C and 32°C).
