Brief Summary

The purpose of this study is to explore the treatment of Low Level Light Therapy(LLLT) mitigate possible insomnia and psychological symptoms, when nurses have taken shifts.The investigators hope that the goal of this interventional research is to improve sleep quality and psychological symptoms of shift nurses in order to promote health.

Shift Work Type Circadian Rhythm Sleep Disorder

Keywords

Anxiety; Depression; nurses; LLLT

Outcome Measures

Primary Outcomes (1)

• psychological symptoms

  use scale:Depression Anxiety Stress Scale-21(DASS-21)measure psychological symptoms.There are a total of 21 questions on the scale, each with a score of 3 and a score of 0 to 63. The higher score mean a worse outcome,mean psychological symptoms are severe.The higher the score the more severe the symptoms, the lower the score the more minor.

  1 month,up to 4 weeks.measure every 1 week.Change from baseline DASS-21 at 1,2,3,4 weeks, a total of five times.

Secondary Outcomes (2)

• sleep symptoms

  1 month,up to 4 weeks.Change from baseline ISI at 2,4 weeks.

• instrument:Heart rate variability(HRV)

  Measure three days a week, two time points (T0, T1) for each measurement, T0=baseline, and T1=after 30mins,24 times in both groups.
