Find a relaxing and quiet place to sit down. Close your eyes, and begin by breathing in deeply through your nose from your belly up. Count to five, inhaling the entire time. Even when you think you can’t inhale any more, try to squeeze a little more air in. Allow your lungs and stomach to fully inflate. This enables oxygen to reach the deepest depths of your lungs to inflate all the alveoli and break up any toxins and pollutants that may have accumulated. Hold your breath for several seconds and then exhale over the course of another five count. When you think you can’t exhale any more, keep blowing from the deepest depths of your lungs and stomach! You should feel your chest and abdomen flatten inward. Repeat this breathing exercise 9 times. Performing this exercise on a daily basis will not only help cleanse your lungs, but it also helps relieve stress. It won’t take long before you notice positive improvements!
