Though the act of mowing one's lawn is rigorous, it is a great form of exercise, which exposes one to fresh, outdoor air and sunshine. However, precautions need be taken against the inhalation of airborne irritants and pollutants, as well as against the suns powerful rays by appropriately applying sunscreen to exposed skin.

It is also important to note that proper handwashing is a must after working in any outdoor environment to remove contaminants from the skin surface, and from beneath the fingernails, including viruses such as H1N1.
