Survey study, 2007

# Are women with severe premenstrual symptoms more sleepy before their period?

Yes, women with significant emotional or behavioral premenstrual symptoms are sleepier during the late-luteal phase before their period than women with minimal symptoms. However, this sleepiness is not explained by worse nighttime sleep.

 Early or limited evidence

10 women with significant emotional/behavioral premenstrual symptoms and 9 control women, mean age 26 years

## What they did

A study where 10 women with significant premenstrual symptoms and 9 women with minimal symptoms (mean age 26 years) spent one night in a sleep laboratory during the follicular phase and two nights during the late-luteal phase, including one with a 40-minute nap opportunity. Researchers measured sleep patterns, daytime sleepiness, and body temperature.

## What they found

Women with significant symptoms were sleepier and less alert during the late-luteal phase compared to women with minimal symptoms. Both groups had less deep sleep and more light sleep during the late-luteal phase. Body temperature was higher in both groups. The increased sleepiness in women with symptoms was not explained by differences in nighttime sleep or napping.

## What it means for you

Severe premenstrual symptoms are linked to increased daytime sleepiness before your period, even though nighttime sleep doesn't necessarily become worse. This is a small study, so results need confirmation in larger groups.
