So does drinking water help sickness go away? Not directly, no. It’s not the knight in shining armor that slays the dragon. But it is the squire who makes sure the knight has sharp armor and a full canteen. Without the squire, the knight is just a sad guy in heavy metal passing out from heat stroke.
Next time you are that puddle of misery on the sofa, don’t roll your eyes at the advice. Take a sip. Then take another. It won’t cure you overnight, but it will make the journey of being sick feel a lot less like a trek through the Sahara. Your body is doing heavy lifting—at least help it lift with a full tank.
