#5. Take a power walk to beat a midday slump
Call it the 20-20 rule. As little as 20 minutes of low-intensity aerobic activity such as walking can give you a 20 percent surge in energy. Brain chemicals such as dopamine and serotonin are altered and cause the improved energy. Besides, that quick recharge just burned about 75 calories. Sure beats adding 250 spike-then-slump calories’ worth of Skittles.
