Partial- and whole-body thermal sensation and comfort, Part I: Uniform environmental conditions
نویسندگان
چکیده
Subjects exposed to uniform environments were polled for their local and overall (whole-body) thermal sensation and comfort. Sensation and comfort for local body parts vary greatly. In cool environments, hands and feet feel colder than other body parts. The head, insensitive to cold but sensitive to warm, feels warmer than the rest of the body in warm environments. Overall sensation and comfort follow the warmest local sensation (head) in warm environments and the coldest (hands and feet) in cool environments. Subjects evaluate neutral conditions as “comfortable”, never “very comfortable”, and overshoot of sensation and comfort during wholebody step-changes is small.

متن کاملRegional differences in temperature sensation and thermal comfort in humans.
Sensations evoked by thermal stimulation (temperature-related sensations) can be divided into two categories, "temperature sensation" and "thermal comfort." Although several studies have investigated regional differences in temperature sensation, less is known about the sensitivity differences in thermal comfort for the various body regions. In the present study, we examined regional difference...
