No evidence of higher peak heat tolerance in the afternoon or with opportunity for thermal behaviour during low‐intensity work in uncompensable heat

open access: yesExperimental Physiology, EarlyView.
Abstract Heat tolerance is known to be limited by high brain temperature, but most findings pertain to strenuous exercise following artificially altered baseline temperature or with limited opportunity for behaviour. Therefore, we investigated the hypotheses that thermal perceptions, hyperventilation and cerebrovascular responses would be exacerbated ...
