Here’s where it gets fun. Caffeine is a diuretic. It pees out water.
So if your headache is from dehydration, coffee is a double-edged sword. It might help with the pain (caffeine boosts painkillers), but it also dries you out.
One study showed that combining a little caffeine with water worked best. But too much caffeine? You’re back to square one.
It’s a delicate dance. You’re a headache detective. Drink water first. Then consider the coffee.
