In the tropics, the desert or at high altitudes you can get sunburned surprisingly quickly, even through cloud cover. Use a sunscreen, a hat and barrier cream for your nose and lips.
Calamine lotion is a good way to soothe mild sunburn.
Protect your eyes with good quality sunglasses, particularly if you will be near the sand, sun or snow. Prickly Heat Prickly heat is an itchy rash caused by excessive perspiration trapped under the skin. It usually strikes people who have just arrived in a hot climate. Keeping cool but bathing often, using a mild talcum powder or even resorting to air-conditioning may help until you acclimatize. Heat Exhaustion Dehydration and salt deficiency can cause heat exhaustion.
