By combining ingredients such as Ginseng, Guarana, and Caffeine,energy drinks and bars give you a quick boost of energy by increasing your heart rate. About an hour later you can actually feel more fatigued and less energetic than you were before you bought this energy booster.

There are a few things that you can do to keep your energy levels at an even keel, and not have any of the “crash and burn” symptoms later in the day. The first thing you need to do is get a good nights rest. Medical research says you should go to bed and get up at the same time each day. Getting your body on a set schedule, supplies it with a memory of when you should be alert and awake and when you should be relaxed and asleep.

If you fill yourself full of sugary, fatty foods, you will get that initial burst of energy, but may feel overly full and sluggish half an hour later. Eat more fresh fruits and vegetables, drink plenty of water, and exercise every day.

Pack small, healthy snacks or meals the night before,using fresh fruits, veggies,low fat yogurt, tuna or whole grain mini sandwiches. By raining yourself to eat differently, you can be healthier and keep your energy levels at an even keel all day.

Get your exercise by using the stairs instead of the elevator, park at the end of the lot and walk the distance, walk around the building once or twice on breaks and lunch time, and walk to someone else s desk instead of e-mailing them.
