My HormonologyWhether you find it difficult to push yourself to exercise or you’re a gym rat who loves to work up a good sweat, here’s one more good reason to be regularly active: A new study reveals that doing so can reduce symptoms of premenstrual syndrome (PMS), such as irritability, the blues and sensitivity to pain.

In the study, a group of sedentary women suffering from PMS who did 60 minutes of aerobic exercise three times per week (such as brisk walking, biking or swimming) saw significant improvements in their symptoms after just eight weeks.

It may be that exercise helps reduce hormone imbalances that can trigger premenstrual symptoms and/or working out triggers a higher production of brain chemicals that boost mood and mask pain.
