4. Pep up your workout
Studies show that the aroma and taste of peppermint can boost energy and make exercise feel easier. Put a dab of peppermint essential oil on the towel you use to wipe your forehead, or put some into a diffuser before you pop in an exercise DVD.
Tip: Fill your water bottle with unsweetened peppermint iced tea and take a sip during a workout. Researchers say it increases alertness and even improves endurance.
