In today’s world with its rampant air pollution, we should all be concerned with the health of our lungs. Obviously, the most important step for maintaining healthy lungs is not smoking. But if you are already a non-smoker, then consider additional steps to ensure healthy lungs. First, avoid areas with poor air quality as much as possible. This means staying indoors during rush hour and not spending times in smoky cafes or bars. Make sure to get enough exercise, by taking long walks or hikes as this will boost the strength of your lungs. Finally, eat apples and garlic, as both of these appear to contribute to healthy lungs.
