Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
