Why Period Cramps Hurt So Much π£ β The Science Explained!
Menstrual cramps happen for a reason! π£ Every month, if an egg isnβt fertilized, your uterus sheds its lining (endometrium).
Hereβs what happens:
πΉ Special chemicals called prostaglandins trigger uterine muscle contractions
πΉ Contractions help push out blood and tissue
πΉ Nearby blood vessels get compressed, reducing oxygen to muscles
πΉ Pain signals travel to the brain, causing cramps in your lower abdomen, back, or legs
Cramps can range from mild to severe, but theyβre a normal sign that your body is working in rhythm with your menstrual cycle.
π‘ Learn why some periods hurt more than others and how your body naturally prepares for the next cycle.
