Survey study, 1998

Does exercise help PMS?

Exercise was not linked to having less PMS. However, women with PMS who exercised regularly had significantly less anxiety than sedentary women with PMS.

Early or limited evidence 19 regularly exercising women and 20 sedentary women

What they did

Researchers compared 19 women who exercised regularly with 20 sedentary women. They tracked PMS symptoms across the menstrual cycle and measured anxiety levels.

What they found

The proportion of women with PMS did not differ significantly between the exercise and sedentary groups. Among women with PMS, those who exercised regularly had significantly reduced anxiety compared to those who did not exercise.

What it means for you

Exercise does not appear to prevent or reduce PMS itself, but may reduce the anxiety that often comes with PMS. The widespread belief that exercise helps PMS may actually come from its anxiety-reducing effects. This study was small and had no intervention group, so we cannot confirm exercise caused the anxiety reduction.
