1. Drink a BIG glass of water.
Water is and will (probably) always be the most needed resource for the human body. After going 6-8 hours without any, it's no surprise that you need to replenish. Drinking a glass of water immediately after waking up in the morning will give your body what it needs and lower your chances of being tired and dehydrated later in the day.
2. Go for a run.
Running in the morning can be an excellent way to wake up both your body and your mind with endorphins. After a nice half-hour run and a shower, there's little chance you are going to be feeling sluggish and lethargic when you get to school, work, etc. Plus, you can go through the rest of your day with the satisfaction of knowing you've already worked out and have one victory under your productivity belt.
3. Drink a cup of coffee and read a good book.
I know some people don't drink coffee, and that's okay; tea or hot cocoa would do the trick as well (although you will miss out on the caffeine buzz...) This method is a simple and relaxing way to ease yourself into the day. I find that the mixture of the caffeine in the coffee and getting lost in a book does wonders for getting my mind turned on and energetic. Just be careful not to delve into something that's a bit dull or dry or you may find yourself falling right back asleep.
4. Cuddle your significant other or your pet.
This is just a really easy way to start your day on a positive note. Showing love and affection to others generally brings love and affection back to us. We are also more likely to love and nurture ourselves if we do so for others, so why not start that cycle first thing in the morning?
5. Spend some time outside.
Whether you're going to mow the lawn, work in the garden, or simply stare at a tree for 10 to 20 minutes. Being outside in the fresh air excites the senses and pulls you away from the strong, persistent grip of sleepiness. There's just something about being outside and breathing the nice fresh air that opens up and excites your mind.
