Sleep Quality and Perceived Stress Among Women

A pilot study evaluating 24 women using Somavedic Luna observed statistically significant improvements in sleep quality and a noticeable reduction in perceived stress, alongside reported gains in daily energy and physical comfort.

Participants and methods

PRUVN evaluated 24 women aged 30–40 who reported poor sleep and high perceived stress. Participants used Somavedic Luna at home and completed questionnaires before and after use.

The measures included the Pittsburgh Sleep Quality Index (PSQI), Perceived Stress Scale (PSS), Fatigue Assessment Scale (FAS), and custom questions about mood, energy, comfort and wellbeing. Changes were compared with each participant’s starting scores, using a statistical significance threshold of p < 0.05.

Results

  • Global PSQI sleep-quality scores improved significantly. PSS perceived-stress scores decreased by 7.5%, also a statistically significant change.
  • The report also identified statistically significant improvements in mood (+8.5%), energy (+10%), physical comfort (+13.3%) and aches and pain (−8.6%).
  • The separate custom sleep-quality question improved by 5%; this change was not statistically significant. Custom anxiety, stress, relaxation, mental acuity, fatigue and overall wellbeing scores, and the FAS score, also showed no statistically significant change.

Study context

The comparison was with participants’ own starting measurements, without a separate control group or blinding. The findings describe self-reported changes in this group of women. The report does not specify the duration of device use.
