Influence of Ambient Temperature on Office Behaviors

Completed · Not applicable

Conditions studied: Obesity

In brief

Based on preliminary data and previous studies, we hypothesize that the ambient temperature experienced by an individual influences his or her food intake. Specifically, exposure to temperatures above the thermoneutral zone (TNZ) will decrease consumption in young adults in a sedentary situation. Researchers will execute a crossover randomized control trial specifically testing thermal exposure and its effect on individual female's food consumption.
