During hot weather it is important to cover not only the eyes, but also the entire head against the harmful effects of UV radiation. Hours of exposure to the sun can lead to skin burns, migraines, dizziness and even heat stroke. A light and airy hat with a wide brim that also protects the face and neck will provide the best protection. Elegant straw hats are increasingly replacing those made of plastic. They are affordable and available on stalls in almost every seaside resort.
