Survey study, 2020

Can exercise and bright light help with depression in women with PMS?

In this study, women with PMS who added regular exercise and bright light exposure to their routine ended up with lower depression scores than those who didn't, but because the groups weren't randomly assigned we can't be fully sure the therapy itself caused the difference.

Early or limited evidence 803 women with PMS in a community depression and anxiety program, mean age 38.8

What they did

1,968 women in a community mental-health program were surveyed; 803 reported PMS (mean age 38.8). All filled out a 75-item depression questionnaire at start and end. The program taught exercise (40+ min, 5x/week) and bright light exposure (20-40 min/day). Groups were not randomised: 280 women adopted the routine, 125 did not.

What they found

Average depression score at the start was 15.3 (SD 15.3). Among those who adopted the exercise and light routine, the end-of-program average dropped to 6.2 (SD 5.5), and 29.6% said they no longer had PMS symptoms. Among those who didn't adopt it, the average was 7.7 (SD 5.5), with 27.2% symptom-free.

What it means for you

Exercise and light exposure may help ease PMS-related depression and could be a drug-free option worth considering, but this wasn't a controlled experiment: groups chose their own routine rather than being randomly assigned, so other factors could explain the difference.
