Descriptive statistics of daily stress and sleep reactivity.

	Predictor	Outcome	M (SD)
Sleep reactivity (to stress)	Stress	Diary TST	−0.08 (0.072)
	Stress	Acti TST	−0.036 (0.028)
	Stress	Diary sleep efficiency	−0.058 (0.068)
	Stress	Acti sleep efficiency	−0.008 (0.001)
Stress reactivity (to sleep)	Diary TST	Stress	−0.108 (0.078)
	Acti TST	Stress	−0.089 (0.068)
	Diary sleep efficiency	Stress	−0.036 (0.039)
	Acti sleep efficiency	Stress	−0.016 (0.001)

All reactivity scores are standardized. Bolded reactivity indices are the ones that significantly differ across individuals.
