Skin cancer is one of the most common and preventable forms of cancer. Apply SPF of at least 30 to 50—every two to four hours you are outdoors or riding in a car. Routinely wearing a quality pair of sunglasses protects the eyes from cataracts, a condition common among older adults. Look for a pair with a label showing they block 100% of UVA and UVB rays. As we grow older, the body doesn’t adjust to changes in temperature and humidity as quickly as in younger days. This puts seniors at higher risk for dehydration and sun-related illnesses, like heat stroke – so make sure to keep hydrated!
