Sleep and HRV measures in the participants. Data is displayed as mean ± standard deviation (minimum - maximum). HF[ms2]: Absolute power of high frequency heart rate variability; %N1-REM: Proportion of the sleep stage to the total sleep time; REMD: REM density; REMF: REM fragmentation; REML: REM latency; RMSSD: Root mean square of successive differences.

| REML | 102.3±45.9 (0–238.0) |
| REMF | 9.8±4.0 (2.8–23.4) |
| %N1 | 5.7±3.8 (0.8–27.0) |
| %N2 | 54.5±9.3 (26–81.7) |
| %N3 | 21.7±10.6 (1.7–63.3) |
| %REM | 18.3±6.5 (2.0–35.0) |
| HF[ms2] | 1198.0±1069.5 (39.2–4788.6) |
| RMSSD | 54.3±26.8 (13.0–128.3) |
