What this Trial Is About
The goal of this clinical trial is to determine if attenuations in cardiac output drive the blunted blood pressure response during cycling exercise following a night of partial sleep deprivation in young healthy adults (%50 females). The secondary outcome is to assess sex differences. The main questions it aims to answer are: * Do reductions in plasma volume drive reductions in cardiac output and therefore blood pressure during exercise following a night of partial sleep deprivation? * Do sex differences exist? Participants will: * Visit the lab after a night of normal sleep and a night of partial sleep deprivation. * Keep a daily diary of their sleep and food/beverage intake. * Perform maximal and submaximal exercise on a cycle ergometer.
