About this study
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Visual stimulationOther
Participants will watch a 10-minute snow- or fire-themed video
Acoustic stimulationOther
Participants will listen to a natural sound from fire burning or snow falling
CombinationOther
Participants will undergo both visual and acoustic stimulation
| Study group | Role | What they receive |
|---|---|---|
| Climate-controlled chamber | Experimental | Participants will be in a climate-controlled chamber. Temperature will vary by 5 degrees both warmer and colder. Receives: Other: Visual stimulation; Other: Acoustic stimulation; Other: Combination |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in thermal perception
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).
Measured: Baseline to 90 minutes
Change in pulse rate
Pulse will be measured using the Empatica Plus 4
Measured: Baseline to 90 minutes
Change in skin temperature
Skin temperature will be measured at 14 sites using iButtons (DS1922L)
Measured: Baseline to 90 minutes
Change in blood pressure
Measured using an automatic blood pressure monitor
Measured: Baseline to 90 minutes
Change in core temperature
Measured using CORE core temperature device.
Measured: Baseline to 90 minutes
