Heat stress profoundly and unanimously reduces orthostatic tolerance. This review aims to
provide an overview of the numerous and multifactorial mechanisms by which this occurs in …

The purpose of this consensus document was to develop feasible, evidencebased
occupational heat safety recommendations to protect the US workers that experience heat …

Hemorrhage is a leading cause of death in military and civilian settings, and~ 85% of
potentially survivable battlefield deaths are hemorrhage-related. Soldiers and civilians are …

Heat stress followed by an accompanying hemorrhagic challenge may influence
hemostasis. We tested the hypothesis that hemostatic responses would be increased by …

Compensatory reserve represents the proportion of physiological responses engaged to
compensate for reductions in central blood volume before the onset of decompensation. We …

Exercise requires the integration of physiological mechanisms to enable both the respiratory
and cardiovascular systems to support the increased metabolic demands. During exercise …

Military and civilian emergency situations often involve prolonged exposures to warm and
very humid environments. We tested the hypothesis that increases in core temperature and …

Athletes and certain occupations (eg, military, firefighters) must navigate unique heat
challenges as they perform physical tasks during prolonged heat stress, at times while …

Thermoregulation is a process that allows us to maintain body core internal temperature.
Without thermoregulation, it would be impossible to maintain body functional capacity. All …

The time necessary for the initial appearance of ingested water as sweat during exercise in
the heat remains unknown. Based on the current literature, we estimated fluid transition …
