1. Take a deep breath
Giving your energy level a quick boost can be as easy as taking a deep breath. Dr. Woodson Merrell, author of Power Up, suggests the following: Inhale quietly and slowly, allowing your abdomen to rise, to the count of 4, pause holding the air lightly to the count of 4, exhale slowly, allowing your abdomen to contract, to the count of 6. Repeat four times. The simple act of slow, deep breathing can be incredibly energizing—and relaxing.
