# Do sleep problems make PMS worse in shift-working nurses?

Yes, poor sleep quality and irregular sleep times are linked to worse PMS. Sleep quality also explains how work stress affects PMS.

 Moderate study design

258 nurses working shift schedules including night shifts

## What they did

Secondary data analysis of 258 nurses working shift schedules including nights. Researchers measured PMS, sleep patterns, sleep quality, and work stress using standardized questionnaires and devices like actigraphs.

## What they found

Average PMS score was 53.95, average sleep time was 7.52 hours, and sleep variability was 32.84%. Poor sleep quality and more irregular sleep times were both linked to worse PMS. Sleep quality completely explained the link between work stress and PMS.

## What it means for you

For shift nurses, improving sleep consistency and quality might help PMS symptoms. This study only included nurses, so results may not apply to other women.
