Our bodies are mostly water, yet the reality is most of us are partially dehydrated almost all the time. Now add an illness or hangover, and it causes us to dehydrate further. Your brain is just a big sponge full of fluid, and when alcohol or illness dehydrates us, that sponge dries out, leaving us with a pounding headache. By the time we realize it and start trying to hydrate, we’re already way behind. Drink as much water as you want—only about 50% will get absorbed, and it usually takes several hours before you’re re-hydrated and feeling better again. The quickest and most effective way to relieve the dehydration and replace vitamins and electrolytes is through IV therapy. In roughly half an hour, we can deliver a liter of fluids with electrolytes and vitamins directly into your bloodstream, resulting in the quickest and most effective form of rehydration.
