Key points • The capacity for humans to withstand a haemorrhagic challenge is reduced while heat stressed. • Identification of changes in central blood volume during simulated haemorrhage may help identify the mechanisms by which tolerance to haemorrhage is reduced during heat stress. • We found that the magnitude of reduction in central blood volume to a simulated hemorrhagic challenge is approximately three fold greater when individuals are heat stressed. • Volume loading did not change the relative magnitude of the reduction in central blood volume to that simulated haemorrhagic challenge. • These data show that greater reductions in central blood volume during a simulated haemorrhagic challenge while heat stressed may be a primary mechanism for impaired capacity to withstand that challenge in this thermal condition. |
