Antarctica has an extreme environment. The cold is a major health hazard. In the Northern Hemisphere, several homeless people die from hypothermia every winter. Visitors should be properly prepared and equipped for any visit. Waterproof and windproof gloves, coat, pants, and boots are an absolute necessity.
Other necessities that are often overlooked include sunscreen and sunglasses - summertime visitors will be exposed to the sun's rays from above and from reflections off of snow, ice, and water. Additionally, for those arriving by boat seasickness medicine is strongly encouraged - even the most seaworthy individual will feel queasy in a severe storm; check with your doctor before visiting to determine what medicine is appropriate.
