Heat stress increases human morbidity and mortality compared to normothermic conditions.
Many occupations, disease states, as well as stages of life are especially vulnerable to the …

Heat stress, whether passive (ie exposure to elevated environmental temperatures) or via
exercise, results in pronounced cardiovascular adjustments that are necessary for adequate …

Heat and cold stresses have direct impacts on many of the fundamental control mechanisms
of stroke volume, such as preload, afterload, diastolic function or compliance, and systolic …

Humans control their core temperature within a narrow range via precise adjustments of the
autonomic nervous system. In response to changing core and/or skin temperature, several …

The sympathetic nervous system is a ubiquitous, integrating controller of myriad
physiological functions. In the present article, we review the physiology of sympathetic …

Passive heat stress reduces arterial carbon dioxide partial pressure () as reflected by 3 to 5
Torr reductions in end‐tidal carbon dioxide tension (). Heat stress also reduces …

The Frank–Starling 'law of the heart'is implicated in certain types of orthostatic intolerance in
humans. Environmental conditions have the capacity to modulate orthostatic tolerance …

This review provides an in‐depth update on the impact of heat stress on cerebrovascular
functioning. The regulation of cerebral temperature, blood flow, and metabolism are …

Higher oscillations of cerebral blood velocity and arterial pressure (AP) induced by
breathing with inspiratory resistance are associated with delayed onset of symptoms and …

We investigated 1) the regional distribution of cerebral blood flow (CBF), 2) the influence of
end-tidal Pco2 (PetCO2) on CBF, and 3) the potential for an extracranial blood “steal” from …
