San Diego, California - A hat can make your summer outfit that much more attractive. 

Hats can also prevent melanoma or skin cancer, particularly if you are older and especially if your hairline is receding, adds the Association of Mature American Citizens.  And, while you are at it, don't forget to use a sunscreen that protects against both UVA and UVB rays, with an SPF factor of 15 or higher, when you go out of doors.  Those UV rays are not only harmful for your skin, they can damage your eyes, so get yourself a good pair of shades that block those harmful rays.  Besides, says AMAC, sunglasses will make you look cool.
