Why it matters

PMS severity isn't fixed — it varies significantly from cycle to cycle based on lifestyle factors. Sleep quality in the luteal phase, alcohol consumption, dietary magnesium and B6 intake, stress load, and exercise frequency all affect how severe your PMS symptoms are. The cycles where PMS is worst are almost always cycles where several of these lifestyle factors went in the wrong direction simultaneously. Knowing which lifestyle factors amplify your PMS lets you meaningfully reduce its severity without medication.

When Normal helps

Normal tracks your PMS symptoms alongside your lifestyle patterns across multiple cycles. It finds which specific lifestyle factors — sleep, alcohol, stress, nutrition, movement — are most consistently associated with your worst PMS cycles versus your manageable ones.

How Normal finds it

Tell Normal about your PMS symptoms and when they start each cycle. Tell it how you've been sleeping, eating, moving, and managing stress. Over three to four cycles it finds the lifestyle patterns that are amplifying your PMS and the ones that reduce it.
