The most helpful things you can do fall into two categories: reducing the physical pain itself and taking stress off her plate so she can rest. Period cramps are caused by real, measurable uterine contractions, not unlike labor contractions in miniature, so the pain is genuine and sometimes severe. Knowing what actually works, and showing up without being asked, makes a bigger difference than you might expect.
Why Period Cramps Hurt So Much
During menstruation, the uterus releases chemicals called prostaglandins that trigger contractions to shed its lining. These contractions squeeze blood vessels feeding the uterine muscle, temporarily cutting off oxygen, which is what produces the cramping pain. Some people naturally produce more prostaglandins than others, leading to more intense and prolonged cramps. This isn’t something she can control or push through with willpower. When cramps are bad, the pain can radiate into the lower back and thighs, and it often comes with nausea, fatigue, or headaches.
Heat Is Your Best Tool
A heating pad or hot water bottle on her lower abdomen is one of the most effective things you can offer. In a clinical trial comparing heat therapy to ibuprofen, 70% of participants using a heated patch achieved complete pain relief, compared to 55% using ibuprofen alone. That’s not a typo: heat outperformed a standard dose of anti-inflammatory medication. When the two were combined, relief came faster, especially in the first few hours.
Keep a heating pad plugged in and ready, or pick up adhesive heat patches she can wear under clothing. A warm bath works too. The heat relaxes the uterine muscle and improves blood flow to the area, directly counteracting what prostaglandins are doing. If she’s lying on the couch, bring her the heating pad before she asks for it.
Help With Pain Relief Timing
If she takes ibuprofen or naproxen for cramps, timing matters more than most people realize. These medications work by blocking prostaglandin production, so they’re far more effective when taken before the pain peaks. The ideal approach is to start taking them at the very first sign of cramps, or even the day before her period is expected to start, and continue on a regular schedule for the first two or three days. Waiting until pain is already intense means prostaglandins have had a head start, and the medication has to play catch-up.
You can help by keeping track of her cycle (plenty of apps allow partner access) and making sure she has medication on hand. Bringing her ibuprofen with a glass of water and a small snack (these medications are easier on the stomach when taken with food) is a simple, thoughtful move.
Food and Drinks That Actually Help
What she eats in the days around her period can dial cramp severity up or down. Refined sugar, red meat, dairy, fried foods, and coffee all promote inflammation and may increase prostaglandin release, which worsens cramping. Alcohol does the same. A research review found that meat, sugar, salt, oil, and coffee were all associated with more painful periods.
This doesn’t mean you should police what she eats. It means you can cook or order meals that happen to be helpful: salmon or other fatty fish, leafy greens, whole grains, fruits, and nuts. Anti-inflammatory foods work by keeping prostaglandin levels in check. Herbal tea (ginger or chamomile) is a good swap for coffee on heavy cramp days, and staying well hydrated helps reduce bloating and fatigue.
On the supplement side, magnesium (300 to 600 mg daily) and vitamin B1 (100 mg daily) have both shown benefits for reducing cramp severity when taken consistently over one to three menstrual cycles. These aren’t instant fixes, but if her cramps are a recurring problem, picking up a bottle of magnesium and suggesting she try it is a practical gesture.
Gentle Movement Helps (If She’s Up for It)
Exercise is probably the last thing she wants to hear about when she’s curled up in pain, but light movement genuinely reduces cramp severity. A clinical trial found that both aerobic exercise and yoga, done three times a week for about two menstrual cycles, significantly decreased pain, reduced stress and anxiety levels, and improved quality of life. The two approaches were equally effective for pain relief, though aerobic exercise had a slight edge for overall physical function.
The key word here is gentle. A slow walk around the block, some easy stretching on the floor, or a 20-minute yoga video can help increase blood flow to the pelvic area and release tension. Offer to do it with her. Don’t push it if she says no.
Take Things Off Her Plate
Pain is exhausting, and the mental load of daily tasks makes it worse. One of the most meaningful things you can do doesn’t involve any medical knowledge at all: just handle the logistics of life for a day or two. Do the dishes, take care of dinner, walk the dog, run the errand she was going to do. If you live together, clean the bathroom or do laundry without being asked.
Ask her directly what would help most. Some people want company and physical comfort (a back rub, someone to watch a movie with). Others want to be left alone with a heating pad and a dark room. Don’t assume. The question “What do you need right now?” is more useful than guessing, and it signals that you’re paying attention and available without being overbearing.
If you can roughly predict when her period starts, plan ahead. Stock the fridge, clear your schedule for that evening, have heating patches and her preferred snacks ready. Anticipating what she’ll need before symptoms hit shows a level of care that’s hard to fake.
When Cramps Might Be Something More
Normal period cramps are uncomfortable but manageable. If her pain is so severe that she regularly can’t go to work or school, can’t get through daily tasks, or isn’t getting relief from heat and over-the-counter medication, that’s worth paying attention to. Roughly 1 in 10 women of reproductive age has endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. Signs that cramps may be more than typical include pain during sex, pain with bowel movements, chronic pelvic pain between periods, and very heavy bleeding.
The tricky part is that endometriosis can only be definitively diagnosed through a minor surgical procedure, and many people go years without a diagnosis because they’ve been told their pain is “normal.” If her cramps seem disproportionately severe, you can support her by encouraging her to bring it up with a gynecologist and, if she wants, going with her to the appointment. Sometimes having a partner validate that the pain seems unusual helps someone advocate for themselves in a medical setting where period pain is too often dismissed.
What Not to Do
- Don’t minimize the pain. Saying “it can’t be that bad” or making jokes about periods erodes trust. The contractions are real and measurable.
- Don’t act disgusted. Periods are a basic biological function. If you’re uncomfortable talking about them, work on that privately.
- Don’t take mood changes personally. Hormonal shifts can cause irritability, sadness, or anxiety. If something she says during this time bothers you, bring it up after symptoms have passed, not in the moment.
- Don’t try to fix everything. Sometimes she doesn’t need solutions. She needs you to sit next to her, hand her a warm drink, and acknowledge that it sucks.
