Analyzation of recovery nights
R1R
Between BR and R, there were significant differences in N1 in heart rate, in N1 in pNN50 and during W in SDNN, so we examined if there was a recovery effect during the following two recovery nights.In heart rate we found differences between R and R1R (In SDNN, pairwise comparisons revealed a difference between R (65.25 ms (± 26.73)) and R1R (92.56 ms (± 35.04)) in WASO (Regarding HR and pNN50 in light sleep stage N1 respective WASO, there is a recovery effect within the first two nights following the intervention night towards the values of baseline night.In N1, pNN50 did statistically not differ in BR and R vs R1R and R2R.
