Outcome Measures
Primary Outcomes (1)
The polysomnography between IH group and control group
Before and after the experiment, polysomnography was performed on both the experimental and control groups to record sleep latency, total sleep duration, as well as the duration and proportion of each sleep stage.
Baseline and Day 7
Secondary Outcomes (9)
Concentration of serum parameters between IH group and control group
Baseline and Day 7
The score of Insomnia Severity Index(ISI)
Baseline and Day 7
The score of the Flinders Fatigue Scale (FFS)
Baseline and Day 7

Study Arms (2)
IH group
ACTIVE COMPARATORParticipants will receive 10 times intermittent hypoxia (oxygen concentration: 13%) intervention.
Control group
SHAM COMPARATORParticipants will receive 10 times sham-hypoxia (oxygen concentration: 21%) intervention in 5 days.
Interventions
The intermittent hypoxia protocol refers to four cycles of 5 minutes hypoxia inhaling interval by 5 minutes normoxia, which is performed twice a day (at least 6 hours apart) in 7 days.
The sham intermittent hypoxia protocol refers to 45 minutes normoxia inhaling, which is performed twice a day (at least 6 hours apart) in 7 days.
