First, a quick science snack. Plasma is about 90% water. So when you donate, you’re losing a serious chunk of fluid. Your body is like, “Hey, I’m running on empty here!”
Alcohol is a diuretic. That’s a fancy way of saying it pees out your water. Combine that with your already-thirsty veins, and you’ve got a recipe for a dizzy, headache-prone disaster. You know that awful feeling when you stand up too fast? Multiply it by ten.
Your Blood Pressure is Already Playing Hide and Seek
After donating, your blood pressure can drop. That’s normal. But alcohol? It lowers it even more. You might feel amazing for one second, then wake up on the floor wondering why the ceiling looks so interesting. Not a great look for your Saturday night.
