What researchers measure

Primary outcomes

  1. Insomnia severity index

    The Insomnia Severity Index Scale (ISI) will be used, which scale ranges from 0 to 28, with higher scores representing more severe insomnia. Specifically, 0-5 points represent excellent sleep quality, 6-10 points mean good sleep quality, 11-15 points indicate average sleep quality, and 16-21 points represent poor sleep quality.

    Time frame: 10 days

  2. Pittsburgh Sleep Quality Index

    The Pittsburgh Sleep Quality Index Scale (PSQI) will be used, which scale ranges from 0 to 21, with higher scores representing poorer sleep quality. In detail, 0-7 points represent insomnia of no clinical significance, 8-14 points mean sub-clinical insomnia, 15-21 points indicate moderate clinical insomnia, and 22-28 points represent severe clinical insomnia.

    Time frame: 10 days

Secondary outcomes

  1. Blood cell counts

    Time frame: 10 days

  2. Blood lipid level

    Time frame: 10 days

  3. tumor necrosis factor α [TNF-α], interleukin 1β [IL-1β] and interleukin 10 [IL-10]), 5-hydroxytryptamine (5-HT), norepinephrine (NE), dopamine (DA), brain-derived neurotrophic factors (BDNF).

    Detection of these factors in serum of patients using Elisa kit

    Time frame: 10 days

  4. Finger oxygen saturation

    Time frame: 10 days
