One of the best things you can do after you wake up: drink at least 16oz (500mL) of water. Water fires up your metabolism, hydrates you, helps your body flush out toxins, gives your brain fuel, and may even make you eat less.
Your body is 72% water, and you don’t have enough water in you when you wake up. Drinking a big glass of water first thing in the morning is a great way to rehydrate, and start kicking ass from the moment you wake up.
