| Duration of night waking (minutes) | 89.96 (49.86) | 97.43 (53.91) | −0.59 | – | 0.563 | – |

| Sleep efficiency (%) | 83.77 (9.69) | 81.49 (9.28) | – | −0.035 | 0.972 | – |
| Number of night-time awakenings | 3.45 (0.89) | 2.60 (1.55) | 2.19 | – | 0.049a | 0.67 |
| Regeneration | 2.57 (0.89) | 2.71 (0.79) | – | −1.36 | 0.17 | – |
Notes: Duration of night waking describes the discrepancy between time in bed and the sleep duration. Significant differences (P<0.05) are displayed in bold characters. Higher regeneration scores indicate a better regeneration.
