Interventions
Sleep restriction: a) Reduce bedtime to match actual sleep time, but ≥4.5 hours, and adjust bedtime according to sleep efficiency; b) Avoid daytime naps and maintain a regular wake-up time. Stimulus control: a) Reduce wakeful time in bed and rebuild a positive association between sleepiness and bed; b) Use the bed solely for sleeping and sexual activities; c) Only go to bed when feeling sleepy at night or at the designated sleep time; d) If unable to fall asleep within about 20 minutes of being in bed, leave the bedroom and engage in relaxation activities until feeling sleepy, then return to bed for sleep; if still unable to fall asleep within about 20 minutes, repeat the process; e) Wake up at the same time every morning, including weekends.
