Sunburn easily occurs when tourists enjoy outdoor activities without proper clothing or applying sun protection lotion. The UV radiation on a sunny day in Phuket is very intense. Tourists should always put on sun protection lotion (SPF 15 or above) before sunbathing, swimming or doing other outdoor activities in which they are exposed to the sun. The sun protection lotion should be re-applied on the skin every 2-3 hours. Should tourists get sunburned, they should apply cool gel which can heal skin damage. Avoid sunbathing until the skin fully heals.
