Association between energy indicators estimated every 15 s and heart rate measured every 15 s during the sleep period (HR).

Energy Indicators	Model 1	Model 2
Energy Indicators	Estimate (95% CI)	Estimate (95% CI)
L_Aeq,15s (dB(A)) *	0.85 (0.79;0.90)	0.71 (0.65;0.76)
L_Aeq,aero,15s (dB(A)) *	0.17 (0.04;0.30)	0.005 (−0.13;0.14)
L_A90,15s (dB(A)) *	0.44 (0.36;0.52)	0.18 (0.10;0.25)

Model 1: univariate model including energy indicators separately; Model 2: multivariate model including energy indicators separately together with gender, age, body mass index (BMI), physical activity, tobacco consumption, alcohol consumption, cardiovascular disease, hypertension and elapsed time after sleep onset. * Per 10 dBA increase; Bold values are statistically significant p < 0.05.
