When your period starts, the most effective things you can do are manage pain early, choose the right menstrual products for your flow, stay physically active, and eat in ways that support your mood and energy. Most periods last three to seven days, and the first two days tend to be the heaviest and most uncomfortable. Here’s how to handle each part of it.
Start Pain Relief Early
Period cramps happen because your uterus contracts to shed its lining, and those contractions are driven by hormone-like compounds called prostaglandins. The more prostaglandins your body produces, the stronger the cramps. Anti-inflammatory painkillers like ibuprofen and naproxen work by blocking the enzyme that produces prostaglandins in the first place, which is why they’re more effective for cramps than other painkillers like acetaminophen.
The key is timing. Taking ibuprofen (400 mg every six to eight hours) at the first sign of cramping, or even just before you expect your period to start, prevents prostaglandin levels from building up. Naproxen works similarly, typically starting with a 500 mg dose followed by 250 mg every six to eight hours. Waiting until pain is severe means prostaglandins have already triggered intense contractions, and the medication has to work harder to catch up.
Heat also helps. A heating pad or hot water bottle on your lower abdomen relaxes the uterine muscle directly. Combining heat with an anti-inflammatory painkiller covers both the chemical and muscular sides of cramping.
Choosing and Changing Menstrual Products
Pads, tampons, menstrual cups, and discs all work well when used correctly. The main safety concern is how long you leave them in. The CDC recommends changing pads every few hours regardless of flow, and more often on heavy days. Tampons should be changed every four to eight hours, and you should never leave a single tampon in for more than eight hours. Menstrual cups should be cleaned every day after use.
Leaving a tampon in too long increases the risk of toxic shock syndrome, a rare but serious bacterial infection. TSS affects roughly 0.8 to 3.4 people per 100,000 in the U.S., so it’s uncommon, but the symptoms escalate fast: sudden high fever, a rash that looks like sunburn, nausea, vomiting, muscle aches, and confusion. If you develop these symptoms while using a tampon, remove it immediately and get emergency medical care.
If you find yourself soaking through a pad or tampon every hour for several hours in a row, passing large blood clots, or bleeding for more than seven days, your flow may be heavier than normal. Clinically, heavy menstrual bleeding is defined as losing more than 80 ml of blood per cycle, but a more practical definition is simply bleeding that interferes with your daily life. That’s worth bringing up with a doctor, because effective treatments exist.
Exercise Actually Helps
It’s tempting to skip workouts entirely, but moderate exercise is one of the better tools for reducing period symptoms. A clinical trial published in BMC Women’s Health tested a program of 150 minutes of moderate-intensity walking per week, spread over at least three days, combined with 30 minutes of strengthening and flexibility exercises twice a week. Participants followed this for about 12 weeks and saw meaningful improvement in menstrual symptoms.
You don’t need to push hard. Moderate intensity means a pace where you can still talk but couldn’t sing. Even a 10-minute walk counts as a session. The goal isn’t performance; it’s getting blood flowing, which helps relax uterine muscles and release your body’s natural pain-relieving chemicals. Yoga and stretching also work well, especially poses that open the hips and lower back.
What to Eat (and Why It Matters)
What you eat during your period can directly affect how you feel. Complex carbohydrates like whole grains, oats, sweet potatoes, and brown rice increase levels of tryptophan, a building block your body uses to make serotonin. Since serotonin levels tend to dip around menstruation due to hormonal shifts, eating these foods can help stabilize your mood and reduce irritability.
Staying hydrated is equally important. Water retention and bloating are common during your period, and drinking more water (not less) actually helps your body release that excess fluid. Reducing salt and caffeine intake can also ease bloating and breast tenderness. Iron-rich foods like spinach, red meat, lentils, and fortified cereals help replenish what you lose through bleeding, especially if your flow is on the heavier side.
Managing Mood and Energy
The emotional side of your period isn’t imagined. Fluctuating estrogen levels in the days before and during menstruation trigger a cascade of changes in brain chemistry. When estrogen drops, your brain produces less serotonin, dopamine, and acetylcholine. The result is a real, physiological basis for feeling tired, irritable, anxious, or low. Progesterone shifts compound this by affecting other brain chemicals involved in calm and sleep.
Nonpharmacological strategies that consistently help include regular physical activity, maintaining consistent sleep habits, and avoiding stacking stressful commitments during your heaviest days if you can help it. Warm baths can ease both physical tension and emotional stress. Cognitive behavioral techniques, even informal ones like noticing when your thoughts spiral and consciously reframing them, help some people cope with the more disruptive mood shifts. Complex carbohydrates, as mentioned above, support serotonin production from the dietary side.
If mood symptoms are severe enough to disrupt your work, relationships, or daily functioning every cycle, that pattern may point to premenstrual dysphoric disorder, which is a more intense version of PMS with effective treatment options.
Hygiene Basics During Your Period
Your vagina is self-cleaning, and that doesn’t change during menstruation. Washing the external vulva with warm water is enough. Avoid douching, scented washes, and fragrant wipes, all of which can disrupt the natural pH balance and make infections more likely. Scented pads and tampons fall into the same category.
Change your underwear daily, and if you’re using pads, wearing breathable cotton underwear helps reduce moisture buildup. Washing your hands before and after changing any menstrual product is a simple step that prevents introducing bacteria. If you use a menstrual cup, sterilize it in boiling water between cycles and clean it thoroughly with mild, unscented soap each day during your period.
Comfort Strategies That Make a Difference
Beyond the basics, a few practical adjustments can make your period significantly more manageable. Sleep with a towel under you if you’re worried about leaks, or wear period underwear as backup overnight. Keep a small kit in your bag with extra products, pain relief, and a change of underwear for unexpected heavy days. Dark-colored clothing on your heaviest days removes one more thing to worry about.
Track your cycle with an app or a simple calendar. After a few months, you’ll start to see your own patterns: when cramps are worst, which days are heaviest, and when mood dips tend to hit. That knowledge lets you plan ahead, whether that means pre-dosing pain relief, scheduling lighter workdays, or simply knowing that a rough afternoon is temporary and hormonally driven, not a reflection of anything actually going wrong in your life.
