Note: SD: standard deviation; PSQI: The Pittsburgh Sleep Quality Index; VT: Vitality Scale; MH: Menth Health Scale; HAMD: Hamilton Depression Rating Scale; MHR: Mean heart rate; SDNN: Standard deviation of all RR intervals; nLF: Normalized low frequency; nHF: Normalized high frequency

p-value: adopt paired t-test; *: p < 0.05
