Several things genuinely help with period pain and discomfort, from over-the-counter pain relievers and heat therapy to exercise, supplements, and dietary changes. Most people with painful periods can find significant relief by combining two or three of these approaches. Here’s what works, based on clinical evidence.
Pain Relievers: Which Ones Work Best
Anti-inflammatory pain relievers are the fastest option for cramps. They work by blocking the production of prostaglandins, the chemicals your uterus releases during menstruation that trigger strong contractions, reduced blood flow, and pain. The key is choosing the right one and timing it well.
Naproxen sodium (Aleve) outperforms both ibuprofen and acetaminophen for period pain. In a pooled analysis of five clinical trials involving 443 women, naproxen provided noticeable pain relief within 30 minutes and was significantly more effective than ibuprofen at the six-hour mark. This longer-lasting effect makes it especially useful overnight or during a busy workday.
Ibuprofen (Advil, Motrin) still works well, particularly if you take it early. The best strategy with any anti-inflammatory is to start taking it at the first sign of cramps, or even a few hours before you expect them to begin, rather than waiting until the pain is already intense. Once prostaglandins have already flooded the area, pain relievers have to play catch-up. Acetaminophen (Tylenol) is the weakest option for cramps because it doesn’t reduce inflammation, but it’s a reasonable backup if you can’t tolerate anti-inflammatories.
Heat Therapy Rivals Medication
Applying heat to your lower abdomen is one of the most underrated period remedies. A meta-analysis of randomized controlled trials found that heat patches were actually more effective at reducing menstrual pain than analgesic medication. That’s not a small finding. Heat works by relaxing the uterine muscle, improving blood flow, and reducing the intensity of contractions.
The ideal temperature range is 40 to 45°C (roughly 104 to 113°F), which is what most commercial heating pads and adhesive heat wraps deliver. In the clinical trials, women wore heat wraps for 8 to 12 hours a day during the first two or three days of their period and reported substantial pain reduction. A hot water bottle, microwavable heat pack, or stick-on heat patch all work. The stick-on patches are particularly practical because they stay in place under clothing, letting you go about your day.
Combining heat with a pain reliever often provides better relief than either one alone.
Exercise and Movement
Working out during your period might sound unappealing, but exercise consistently reduces menstrual pain in clinical research. A large network meta-analysis found that all forms of exercise were effective at reducing cramps after eight weeks of regular activity. Aerobic exercise and yoga showed nearly identical pain reductions, so pick whichever you’ll actually do.
The mechanism is straightforward: exercise increases blood circulation, dilates blood vessels, raises your pain threshold, and triggers the release of endorphins. It also shifts your body’s inflammatory response in an anti-inflammatory direction. You don’t need intense workouts. Brisk walking, swimming, cycling, or a 20-minute yoga flow all count. The benefits build over time, so consistency matters more than intensity.
Supplements That Reduce Cramps
A few supplements have decent evidence behind them for period pain. None are miracle cures, but they can take the edge off, especially combined with other strategies.
- Magnesium glycinate helps relax smooth muscle, including the uterus. Cleveland Clinic recommends 150 to 300 milligrams per day, noting that magnesium glycinate is the best-absorbed form for cramps. Taking it daily throughout the month, not just during your period, tends to produce the best results.
- Ginger has anti-inflammatory properties that target prostaglandin production. Clinical trials use 750 to 1,000 mg of ginger powder per day, typically divided into three or four doses, taken during the first three days of menstruation. That’s roughly equivalent to a few capsules of powdered ginger supplement.
- Omega-3 fatty acids from fish oil reduced period pain intensity in a crossover trial after three months of daily supplementation. The effect was strong enough that women needed less ibuprofen as a backup. If you already eat fatty fish several times a week, you may be getting enough. Otherwise, a standard fish oil capsule daily is a reasonable approach.
- Vitamin B6 at doses up to 100 mg per day shows benefit for broader PMS symptoms, including mood changes and premenstrual depression. Doses above 200 mg per day can cause nerve problems, so more is not better here.
Managing Bloating and Fluid Retention
Premenstrual bloating is driven by hormonal shifts that cause your body to hold onto water and sodium. It typically peaks in the days before your period starts and improves once menstruation begins. Cutting back on salty foods during the week before your period can reduce how much fluid you retain. This means watching for hidden sodium in processed foods, restaurant meals, and packaged snacks, not just the salt shaker.
Drinking more water, counterintuitively, can help. When you’re well hydrated, your body is less likely to hold onto extra fluid. Potassium-rich foods like bananas, sweet potatoes, and leafy greens also support fluid balance.
TENS Units for Drug-Free Relief
A TENS (transcutaneous electrical nerve stimulation) unit sends mild electrical pulses through adhesive pads on your skin, interrupting pain signals before they reach your brain. For period cramps, pads are placed on the lower abdomen over the area of pain, using a high-frequency setting (50 to 100 Hz). Several companies now sell small, discreet TENS devices designed specifically for menstrual pain that you can wear under clothing.
TENS won’t eliminate severe cramps on its own, but it’s a useful add-on for people who want to reduce their reliance on medication or who can’t take anti-inflammatories.
Signs Your Pain May Need Medical Attention
Normal period cramps typically start within a few years of your first period, last 4 to 48 hours, and gradually improve as you get older. Pain that gets worse over the years rather than better, lasts longer than two days, or doesn’t respond to anti-inflammatories is a different pattern. This type of pain, called secondary dysmenorrhea, often has an underlying cause like endometriosis or fibroids.
Endometriosis is diagnosed in 25% to 38% of adolescents and young women with chronic pelvic pain. When standard treatments like anti-inflammatories fail to help, that number jumps to 50% to 70%. The pain isn’t always limited to your period. About 63% of young women with endometriosis experience pain both during and outside of menstruation, and roughly a third report intestinal pain or urinary symptoms. If your period pain is severe enough to regularly keep you home from work or school, or if you’re noticing pain during bowel movements, urination, or intercourse, those are patterns worth investigating with a healthcare provider.
