Wear sunscreen, and avoid direct exposure to the sun.

A strong sunscreen and sun-protective clothing can help keep you safe this summer and every day of the year.

With summer here, it's time to reach for the sunscreen. But not everyone is convinced that skin protection is a necessity. "Older adults grew up at a time when unprotected skin exposure wasn't a cardinal sin, and many I talk to think a little sun is good for them. But older adults are actually at an increased risk for skin cancer, since their skin is no longer able to repair damage as efficiently as it once did," says Dr. Oon Tan, a dermatologist at Harvard-affiliated Massachusetts Eye and Ear Infirmary.

Eczema, an itchy, scaly skin disease that usually starts early in life, may make people more prone to heart disease and stroke, according to a study in the Jan. 8, 2015, Journal of Allergy and Clinical Immunology.

Researchers relied on data from more than 61,000 adults who took part in the 2010 and 2012 National Health Interview surveys. They found that people with eczema smoke and drink more and are less likely to exercise than people without the disease. (Sweating aggravates eczema, making exercise a challenge.) Other factors that boost heart disease risk—such as severe obesity, high blood pressure, and high cholesterol—were also more prevalent among people with eczema. So were sleep disturbances, which were linked to even higher odds of having those risk factors.

Long trips come with an increased risk of blood clots deep in the leg veins, which can have serious complications.
