Correlation of Heart Rate with Subjective and Objective Sleep Parameters

Heart Rate [bpm]	∆ Bad	∆ Good	∆ Bad	∆ Good
	Subjective Sleep		Objective Sleep
∆ Sleep Quality	0.193	0.013	0.012	0.283
∆ SOL	0.029	−0.262	0.011	−0.278
∆ WASO	−0.112	−0.304	0.245	0.453*
∆ NWAK	−0.017	0.154	0.085	0.244
∆ Sleep Depth	0.085	0.029	−0.037	0.313

Notes: Correlations were calculated separately for the “good” and “bad” conditions. All parameters are corrected for the values obtained in the neutral condition (∆ Bad: “bad” – “neutral” and ∆ Good: “good” – “neutral”). * Indicates p ≤ 0.05.
