6 Caffeine-free ways to boost energy

Give massaging your ears a try, because all of your body's energy passes through

your outer ear, applying pressure to your ear may help invigorate your entire body. Simply pinch the rim of each ear between your thumb and pointer finger and rub.

And if the light in your office or room is dim, change it. A brighter light will help keep you focused. Blue light will give you a calm alertness while a red light bulb will give you an afternoon wake up call.

Now for tip number five: exercise. Exercise is proven to give you the boost you need while also burning calories. They don't call it runners high for no reason.
