Tip 1: Breathe Clean Air
While this study specifically looked at smoking, countless other studies have linked any form of air pollution to heart disease, cancer, and a shortened life. The message is simple. Make clean breathing a must. In addition to not smoking, you also don’t allow anyone to smoke around you. The same goes for electronic cigarettes. Besides smoking, air pollution can be a huge problem. Indeed, studies show that air pollution may rob you of up to 5.5 years of life! And when it comes to air pollution, indoor air quality is generally much worse than anything you may encounter outside of your home. For indoor air pollution, studies show that even breathing the stench of smoke on the clothes of smokers puts you at risk.
