Whether or not you’re someone who likes to eat first thing in the morning, it is important that you get water into your system as soon as you wake up. Drinking a glass of warm water in the morning not only rehydrates you, but it helps your body prepare for the rest of the day and whatever else you might be eating or drinking. Keeping hydrated in the morning also helps improve your mental performance. If you’d like to up the game a little bit more, add some lemon to the water.
