Figure 7.

Surface temperature over the supraclavicular and sternal area as measured by thermal imaging at 24°C and 18°C (A) over 150 min of thermal challenge. (B) Temperature difference between supraclavicular area and sternal area. (C) Correlation between cumulative energy expended (EE) over baseline after 150 min of mild cold exposure and the change in temperature difference between supraclavicular and sternal areas after 150 min. (D) Correlation between EE over baseline after 150 min of mild cold exposure and sternal temperature after 150 min. (E) Correlation between EE over baseline after 150 min of mild cold exposure and supraclavicular temperature after 150 min.
