If you are planning a trip to a sunny southern destination this winter, don’t forget to pack your sun smarts. Sunny vacation destinations are closer to the equator which means stronger, more damaging rays. A tropical climate is entirely different as the sun intensity is much stronger. The ultraviolet (UV) index is higher in tropical destinations, so it takes less time in the sun before you acquire a sunburn and irreversibly damage your skin. You can find more information on the UV index here.
