Studies<\/a> say somewhere between 45% and 95% of women experience menstrual cramps. That\u2019s a lot of us. And yet, most of us have spent years just\u2026 dealing with it, with no real explanation of why it actually hurts.<\/p>\n \u00a0There is something behind it, and understanding the period pain biochemical causes<\/strong> helps explain how bad your cramps get, how long they stick around, and honestly, why your whole body feels like it\u2019s going rogue every month.<\/p>\n It comes down to a chemical called prostaglandins.<\/p>\n Understanding it doesn\u2019t make the cramps disappear, but it does make them a lot less confusing. Once you know what\u2019s driving the pain, you can actually do something about it.<\/p>\n Prostaglandins are chemicals your body naturally makes. They\u2019re tiny messengers that help different parts of your body talk to each other and respond when something\u2019s up.<\/p>\n Basically, your body\u2019s own internal WhatsApp group, sending quick updates and instructions when needed.<\/p>\n So yes, prostaglandins are behind a lot of the uncomfortable stuff, fever, swelling, diarrhea, cramps, all of it.<\/p>\n Blog continues after the ad.\u00a0<\/em><\/p>\n But they\u2019re not the villain here. They\u2019re simply your body\u2019s way of detecting that something\u2019s wrong, responding quickly, and starting the process of protecting and healing itself.<\/p>\n To really understand how prostaglandins cause period pain<\/strong>, it helps to look at what\u2019s happening inside the uterus each month. Your uterus has a lining (the endometrium) that builds up every month in case of pregnancy. When pregnancy doesn\u2019t happen, your body needs to shed it. That\u2019s your period. Here\u2019s how prostaglandins come into that picture.<\/p>\n So, yes, menstrual cramps are not random. They\u2019re chemistry, and the connection between prostaglandins and menstrual cramps<\/strong> is one of the clearest period cramp causes<\/strong> science has mapped out.<\/p>\n Prostaglandins = Uterine contractions = Period cramps<\/p>\n But don\u2019t worry, Nua\u2019s Cramp Comfort Heat Patch<\/a> heats up in about 15 minutes and lasts up to 8 hours, so you\u2019re covered even during the most intense lower abdominal pain during period<\/strong> days.<\/p>\n Yes. Some of the prostaglandins your uterine lining releases make their way into your bloodstream. And once they\u2019re circulating in your blood, prostaglandin levels during menstruation<\/strong> can trigger reactions in other parts of your body too. Your gut, your muscles, your head. Which is why period symptoms feel so\u2026 everywhere.<\/p>\n So the next time you wonder why your whole body is off during your period, feel free to blame the prostaglandins.<\/p>\n When your body makes more prostaglandins than needed, your menstrual cramps can feel stronger and last longer. And a few everyday things can push those levels up:<\/p>\n Prostaglandins are produced as part of the body\u2019s inflammatory response. So, anything that causes inflammation, such as stress or poor sleep, can make your body produce more prostaglandins (a.k.a. more pain) during your period.<\/p>\n What you eat can affect how many prostaglandins your body makes.<\/p>\n In your teens or early twenties, your body naturally makes more prostaglandins as your period hormones haven\u2019t stabilised yet, which is why cramps can feel worse then. In fact, one study<\/a> found that 84% of women under 25 experience period pain, and 43% feel it every single cycle. But the good news is that it\u2019s temporary, and your menstrual cramps will get better as you grow up.<\/p>\n Some conditions can make your body produce much higher levels of prostaglandins, which is why the cramps feel much more intense than a typical period.<\/p>\n Painkillers and heat therapy are the best 2 ways to fight period cramps.<\/p>\n Painkillers like ibuprofen or naproxen work as prostaglandin inhibitors for cramps<\/strong>, stopping your body from making prostaglandins. Which is why they\u2019re most effective when taken early (before or right as your cramps begin), so they can stop prostaglandins from building up.<\/p>\n But it\u2019s not always easy to time that perfectly, because you don\u2019t always know exactly when your menstrual cramps will start. If you take the meds later, prostaglandins are already formed, so they may not work as well.<\/p>\n Plus, taking medication every month isn\u2019t something everyone is comfortable with, especially at a younger age. They can also come with side effects like acidity, stomach irritation, or nausea.<\/p>\n That\u2019s where simpler, non-medicine options for prostaglandins menstrual pain relief<\/strong> come in, like heat therapy. It helps your body deal with all the chaos that prostaglandins cause.<\/p>\n And interestingly, research<\/a> has shown that heat can be as effective as painkillers for period cramps. In fact, to date, around 50% of women rely on heat therapy for menstrual cramp relief<\/strong>.<\/p>\n Of course, the only issue is\u2026 you can\u2019t always walk around with a hot water bottle or find a plug point for electric heat pads. That\u2019s where something like Nua\u2019s Cramp Comfort Heat Patch<\/a> makes life easier. You just stick it onto your underwear, and it gives you steady, gentle heat while you go about your day.<\/p>\n Heat therapy is often a more reliable, effective, and safer option for period cramps compared to painkillers, and here\u2019s why.<\/p>\nWhat Are Prostaglandins?<\/h2>\n
