Day alarm compared to day control and night alarm compared to night control for pre-treatment heart rate, peak heart rate, and heart rate reactivity measures

Heart rate variable	Day		Night
	Alarm	Control	Alarm	Control
Pre-treatment (beats·min-1)	74±3	73±3	59±3	63±4
Peak during mobilization (beats·min-1)	111±5	80±3*	122±5	93±6†
Reactivity (beats·min-1)	38±5	7±2*	56±4	30±5†

Note: Data presented as mean ± SEM; * denotes day control significantly different to day alarm condition; † denotes night control significantly different to night alarm condition; day conditions N = 12, night conditions: N = 10
