Children are less proficient at regulating internal body temperatures, especially during physical activity, increasing the potential for heat-related illnesses during periods of elevated outdoor temperatures. Recent studies suggest that playgrounds and bounce houses create microclimates with potentially dangerous conditions elevating the risk of heat-related illnesses. The present pilot study extends the inquiry to children's outdoor playhouses to determine if the same capability of creating microclimatic conditions of elevated thermal risk exists. Air temperature ( degrees C) and relative humidity (%) measurements were collected from inside two playhouses and the outside ambient environment over a 6-h period on a clear, warm, summer day. Measurements were used to calculate the National Weather Service (NWS) heat index for both playhouses and the outside environment. Results from a Kruskal-Wallis test demonstrated significant differences (p < 0.001) and post hoc test procedures indicated that playhouse A and playhouse B had significantly higher heat index values than the outside environment. Little is known about the thermal risks created by children's outdoor play equipment. This study adds to the preliminary work in this field, but continued research is warranted to fully understand the thermal safety of children's outdoor play equipment.
