Period cramps happen because your uterus contracts to shed its lining, and the intensity of those contractions depends on your levels of prostaglandins, hormone-like substances that drive pain and inflammation. The higher your prostaglandin levels, the worse the cramping. The good news: multiple approaches can reduce pain significantly, and many of them work as well as painkillers.
Why Period Cramps Hurt
Your uterus is a muscular organ, and during your period it squeezes to push out its lining. Prostaglandins trigger those contractions. They peak during the first two days of bleeding, which is why cramps are usually worst at the start of your period. When prostaglandin levels run high, the contractions can temporarily cut off blood flow to the uterine muscle, creating that deep, achy pain that radiates into your lower back and thighs.
Almost everything on this list works by either lowering prostaglandin production, relaxing the uterine muscle, or interrupting pain signals before they reach your brain.
Take Anti-Inflammatory Medication Early
Over-the-counter anti-inflammatory drugs like ibuprofen and naproxen work by blocking prostaglandin production at the source. The key detail most people miss: they’re far more effective if you start taking them one to two days before your period begins, or at the very first sign of bleeding, rather than waiting until pain peaks. This lines up with when prostaglandin levels start climbing.
For ibuprofen, the standard over-the-counter dose is 200 to 400 mg every four to six hours, up to 1,200 mg in 24 hours. For naproxen sodium, start with 220 to 440 mg, then 220 mg every 12 hours. Take them on a regular schedule for the first two to three days of your period rather than waiting for pain to return between doses. This keeps prostaglandin levels consistently suppressed instead of letting them spike and crash.
Use Heat Therapy
A heating pad on your lower abdomen or back is one of the oldest remedies for cramps, and the evidence behind it is surprisingly strong. A 2025 meta-analysis pooling 22 trials and nearly 2,000 women found that heat therapy provided pain relief comparable to anti-inflammatory drugs. In some comparisons, heat performed slightly better. And it came with about 70% fewer side effects, making it a solid option if painkillers upset your stomach or you prefer to avoid medication.
You can use a plug-in heating pad, a microwavable heat pack, or adhesive heat patches that stick to your skin under clothing. Aim for a comfortable, sustained warmth rather than high heat. Heat works by relaxing the uterine muscle and increasing blood flow to the area, counteracting the constriction that prostaglandins cause. For the best results, combine heat with anti-inflammatories rather than choosing one or the other.
Move Your Body Regularly
Exercise is the last thing most people feel like doing during cramps, but consistent movement across your cycle can reduce how much pain you experience when your period arrives. A clinical trial comparing aerobic exercise and yoga, both done three times per week over two menstrual cycles, found that both approaches reduced pain severity, lowered anxiety and stress levels, improved blood flow to the uterus, and increased quality of life. The type of movement mattered less than doing it consistently.
You don’t need intense workouts. Brisk walking, swimming, cycling, or a yoga flow all count. The benefits build over time, so this is more of a long-term strategy than a quick fix for cramps you’re having right now. That said, gentle movement during your period, like a walk or light stretching, can provide some immediate relief by boosting circulation and releasing endorphins.
Try a TENS Machine
A TENS (transcutaneous electrical nerve stimulation) unit is a small, battery-powered device that sends mild electrical pulses through adhesive pads on your skin. It works by overwhelming the nerve signals carrying pain from your uterus to your brain, essentially turning down the volume on cramp pain. Units cost around $25 to $50 and are reusable.
For period cramps, set the frequency to 80 to 100 Hz with a pulse width around 100 microseconds. The intensity should feel strong but not painful. Place two electrodes on your lower back at roughly waist level and two more either lower on your back (near your tailbone) or on your lower abdomen over the area of pain. You can wear a TENS unit under your clothes during the day, which makes it practical for work or school.
Use Acupressure Points
Two pressure points have the most evidence for menstrual pain relief. The first is SP6, located on the inner side of your calf, about three finger-widths above your ankle bone, just behind the edge of the shin bone. The spot is often naturally tender. Press firmly with your thumb for about one minute, then repeat on the other leg after 20 to 30 minutes.
The second is LI4, found on the back of your hand in the fleshy area between your thumb and index finger. Press firmly and move your thumb in small circles for two to three minutes. You can repeat this several times a day. Neither of these points will replace medication for severe cramps, but they can take the edge off and are useful when you don’t have other options available.
Consider Magnesium and Vitamin B1
Two supplements have decent evidence for reducing period pain over time. Magnesium, taken at 300 to 600 mg daily, decreased menstrual pain compared to placebo across multiple small trials. It helps relax smooth muscle, including the uterine wall. You can also increase magnesium through food: fish, nuts, seeds, and dark leafy greens are rich sources.
Vitamin B1 (thiamine) at 100 mg daily improved menstrual pain in research, but only after at least 30 days of consistent use. This isn’t a take-it-when-you-need-it supplement. Plan on one to three months of daily use before evaluating whether it’s helping. Neither supplement is a substitute for the faster-acting approaches above, but they can reduce your baseline pain level over time so that other remedies work better.
Signs Your Cramps Need Medical Attention
Normal period cramps start within a day or two of bleeding and ease up after two to three days. Pain that falls outside this pattern may signal an underlying condition like endometriosis, fibroids, or adenomyosis. Pay attention if your cramps have gotten progressively worse over time, if pain starts well before bleeding or persists after it stops, if over-the-counter medication barely touches the pain, or if you’re also experiencing unusually heavy bleeding, pain during sex, or pain with bowel movements. These patterns point to secondary causes of cramping that need diagnosis and targeted treatment rather than general pain management.
