简要总结
The goal of this clinical trial is to understand how environmental factors influence comfort and health. The main question it aims to answer is:
- do temperature, visuals, and sounds affect a person's physiology and perception?
Participants will watch short videos in 2 different climate-controlled environments and provide feedback on their thermal experiences.
详细描述
Participants will engage in a series of sessions in a climate-controlled environment, where researchers will manipulate temperature, visuals, and sounds to study their effects on various physiological measurements, including blood pressure, pulse rate, core temperature, and skin temperature. The study will take place in two distinct chambers, with each chamber designed to allow for precise control of environmental variables. Participants will be asked to watch short video clips in different thermal environments and provide feedback on their thermal experiences.

结局指标
主要结局
Change in blood pressure
时间窗: Baseline to 90 minutes
Measured using an automatic blood pressure monitor
Change in core temperature
时间窗: Baseline to 90 minutes
Measured using CORE core temperature device.
Change in thermal perception
时间窗: Baseline to 90 minutes
Thermal comfort will be assessed using a visual analogue scale (VAS) to measure perceptions of thermal sensation, preference, comfort, pleasantness, and self-perceived shivering. The thermal acceptance of the environment will be rated on a binary scale (acceptable/unacceptable).
Change in pulse rate
时间窗: Baseline to 90 minutes
Pulse will be measured using the Empatica Plus 4
Change in skin temperature
时间窗: Baseline to 90 minutes
Skin temperature will be measured at 14 sites using iButtons (DS1922L)
