# Does thinking repeatedly about distressing thoughts make PMS worse, and can being mentally flexible help?

Women who thought repeatedly about worrying thoughts had more severe PMS symptoms. Being mentally flexible did not reduce this effect, meaning the link between overthinking and PMS remained strong and direct.

 Moderate study design

150 women aged 18 to 35

## What they did

150 women aged 18 to 35 completed questionnaires measuring rumination (repeatedly thinking about distressing thoughts), cognitive flexibility (ability to shift and adapt thinking), and PMS symptoms. Researchers used statistical analysis to test whether flexibility reduced the connection between rumination and PMS.

## What they found

Women with higher rumination reported more severe PMS symptoms. Rumination was also linked to lower cognitive flexibility. However, cognitive flexibility did not mediate the connection between rumination and PMS severity, showing that overthinking had a direct impact on symptoms.

## What it means for you

Overthinking directly worsens PMS and being mentally flexible does not change this link. This suggests other psychological factors may be important in PMS. The main limitation is the cross-sectional design, which cannot prove that rumination causes PMS rather than PMS causing rumination.
