The most helpful things you can do for someone on their period come down to reducing physical pain, easing emotional stress, and handling practical needs so they don’t have to. Most people who menstruate experience some combination of cramps, fatigue, bloating, and mood shifts, and the right support can make a real difference in how manageable those days feel.
Help With Pain Relief First
Cramps are usually the biggest complaint, and they have a straightforward cause: the uterus produces hormone-like chemicals called prostaglandins that trigger contractions to shed its lining. Higher levels of prostaglandins mean stronger, more painful cramps. Anti-inflammatory pain relievers like ibuprofen work by blocking prostaglandin production, which is why they’re the go-to for period pain. The key detail most people miss is timing. These medications work best when taken at the first sign of cramping or discomfort, not after the pain has already built up. Taking them with food helps prevent stomach irritation.
Heat is the other reliable tool. A heating pad or hot water bottle on the lower abdomen increases blood flow to the area, which helps clear out the prostaglandins causing the cramping. Research comparing heat therapy to anti-inflammatory medication found that heat can achieve comparable pain relief with fewer side effects. If you’re grabbing supplies for someone, an adhesive heat wrap they can wear under clothes is especially practical since it lets them move around without holding a pad in place. Electric heating pads work well for when they’re on the couch or in bed.
A portable TENS unit is another option worth knowing about. It’s a small device that sends mild electrical pulses through pads stuck to the skin over the painful area. It works by interrupting pain signals and prompting the body to release its own natural painkillers. The evidence on its effectiveness for period pain is still limited, but many people find it helpful, and it’s something they can use at home alongside other methods.
Know What Products They Use
If you’re picking up supplies, ask what they need rather than guessing. Period products vary widely, and everyone has preferences. Here’s a quick overview so you’re not lost in the aisle:
- Pads come in different absorbency levels, from thin panty liners to thick overnight options. They’re the simplest to use and nothing is inserted into the body.
- Tampons also come in sizes based on flow (light, regular, super). They need to be changed every 4 to 8 hours.
- Menstrual cups are reusable silicone cups that hold more blood than tampons or pads and can be worn for 6 to 12 hours. They come in different sizes.
- Menstrual discs are similar to cups but sit in a different position and can be worn during sex. They last 8 to 12 hours and often come in one size.
- Period underwear has built-in absorbent layers and can be worn up to 12 hours depending on the absorbency level. It needs to be washed after use.
If they tell you a specific brand and size, take a photo of the packaging or have them text you a picture. Getting the wrong absorbency level can mean leaks or discomfort.
Why Mood Shifts Happen
Understanding the biology behind mood changes makes it easier to be patient and supportive rather than confused or dismissive. In the days before and during a period, estrogen drops to its lowest point in the cycle. Even in healthy women, low-estrogen phases are associated with increased negative mood. When estrogen is low, the brain’s ability to regulate emotional responses is reduced, which means reactions to stress, frustration, or sadness can feel more intense than usual.
There’s also a memory component that’s worth understanding. During the low-estrogen, high-progesterone phase right before a period, the brain processes and stores negative emotional information more strongly. This means upsetting events or stressful moments can hit harder and linger longer. None of this is exaggerated or “just hormones” in a dismissive sense. It’s a measurable neurological shift that affects how the brain handles emotions.
What this means practically: listen without trying to fix things, don’t minimize what they’re feeling, and avoid suggesting their emotions aren’t real or proportional. Sometimes the most helpful thing you can say is “that sounds really frustrating” rather than offering solutions.
Food, Drinks, and Supplements That Help
Staying hydrated helps with bloating (counterintuitively, drinking more water reduces water retention) and can ease headaches that sometimes accompany periods. Warm drinks like herbal tea do double duty by providing hydration and gentle heat to the abdomen.
Caffeine is worth being mindful about. It causes blood vessels to constrict, which can worsen cramps by reducing blood flow to the uterus. If the person you’re helping is a regular coffee drinker, they don’t need to quit entirely, but scaling back during the worst days of cramping may help. Salty foods tend to increase water retention and make bloating worse, so lighter meals with fruits, vegetables, and whole grains are a better bet.
For longer-term support, magnesium supplements have solid evidence behind them. A study using 250 mg of magnesium daily found significant reductions in PMS symptoms over two menstrual cycles, and combining magnesium with vitamin B6 (40 mg) was even more effective than magnesium alone. These supplements work best when taken regularly rather than just during the period itself. Other research has found magnesium specifically reduces water retention and pain symptoms.
Encourage Gentle Movement
Exercise is probably the last thing someone with cramps wants to hear about, but light activity genuinely helps. The body’s natural painkilling chemicals (beta-endorphins) tend to drop during the premenstrual and menstrual phases, which contributes to pain, headaches, and low mood. Moderate aerobic exercise raises those levels back up.
You don’t need to suggest a workout. Walking, easy swimming, or gentle stretching for about 30 minutes is enough to make a difference. Research on aerobic exercise and menstrual symptoms found that 30 minutes of moderate activity, done 3 to 5 times a week, significantly improved both physical and emotional premenstrual symptoms. Offering to go on a walk together removes the friction of doing it alone and makes it feel like companionship rather than a prescription.
Practical Things You Can Do Right Now
The most appreciated support is usually the simplest. Make tea, bring a heating pad, offer to cook or pick up food so they don’t have to think about it. If you share a household, take over tasks that require standing or bending, like dishes or laundry. Keep their preferred pain relief stocked before they need it. If they want company, be present. If they want space, give it without taking it personally.
Pay attention to their specific patterns over time. Some people have the worst pain on day one, others on day two. Some get intense fatigue, others get nausea. Learning what their period actually looks like for them, rather than assuming everyone’s experience is the same, is the difference between generic helpfulness and support that actually lands.
Signs That Pain Is More Serious
Normal period cramps are uncomfortable but tolerable and shouldn’t force someone to miss work, school, or daily activities. Pain that’s severe enough to regularly disrupt normal life, pain during sex, or pain during bowel movements and urination could point to a condition like endometriosis, where tissue similar to the uterine lining grows outside the uterus. Bleeding is another marker to watch. Clinically heavy bleeding is defined as more than 80 mL per cycle. Practical signs include soaking through a pad or tampon more than once per hour, passing blood clots larger than about an inch in diameter, or experiencing symptoms of iron deficiency like extreme fatigue and dizziness. If any of these patterns are consistent, it’s worth bringing up gently, not as a diagnosis, but as encouragement to talk to a doctor who can investigate further.
