简要总结
To determine whether PS150 (1) reduces insomnia symptoms, (2) improves sleep quality, (3) adjusts autonomic nervous system functioning, (4) reduces the severity of anxiety and depressive symptoms, and (5) adjusts microbiome and endocrine functions.
详细描述
One-hundred-forty participants with self-reported insomnia (PSQI≥ 7 & 22 > ISI ≥ 12) aged between 20 and 60 years old are estimated to be recruited and randomly assigned to two arms, the PS150 group and the placebo group, under the double-blinded trial. Participants take one capsule of probiotics or placebo after dinner for 30 days. Study measures include polysomnography (PSG), subjective sleep, depressive, and anxiety questionnaires, sleep diary, fecal sampling, saliva testing, and urine testing.

主要结局
Polysomnography (PSG)
时间窗: Baseline, day30
According to the polysomnography, we can analysis participants' brain waves (alpha,beta,theta,delta), sleep stages, and autonomic nervous system functioning to evaluate their objective sleep quality.
